Surge In Global Action Highlights Australia’s Stance On Climate Change

Sydney Morning HeraldNick O'Malley

International action on climate change has surged with General Motors announcing it will cease making petrol and diesel cars by 2035 and the United Nations secretary-general calling for wealthy nations to abandon coal and set net-zero emissions targets.

It followed the Biden administration announcing a slew of climate initiatives in the US, including executive orders to create a White House Office of Domestic Climate Policy and a National Climate Task Force, end fossil fuel subsidies, suspend oil and gas exploration on federal land, and place climate change at the “centre of our national security and foreign policy”.

The measures suggest the administration is determined to follow through on the ambitious climate agenda it laid out during the campaign.

Tennant Reed, the principal national adviser at the Australian Industry Group, the peak industry association, said “it is remarkable how much genuine investments of political capital, organisational effort and of personnel the Biden administration – and the Biden campaign before it – has made on climate”.

“They’ve assembled a very strong team, and not just of people who have ‘climate’ in their job title. They are prioritising climate in staffing a range of key policy and economic roles. It is a very big deal,” Mr Reed said.

He said GM’s announcement not only to abandon the manufacture of light internal combustion vehicles but to pursue net-zero emissions by 2040 in its own right suggested that American industry is taking notice of the Biden administration’s ambitions.

UN Secretary-General Antonio Guterres called on wealthy nations to reach key milestones by the time the COP25 climate talks begin in Glasgow in November during an address early on Friday morning, Australian time.

He said nations that were responsible for 65 per cent of global emissions had announced plans to reach net-zero by 2050 and by November he hoped that figure would be 90 per cent.

He said no new coal-fired power plants should be built and wealthy nations should abandon coal by 2030, and all nations aim to end its use by 2040. A carbon price should be embraced and an end date for financing all fossil fuels, starting with coal, should be introduced.

Mr Reed said Australia risked reputational damage if it was seen to be not acting, but he said the government’s funding of new technologies announced last year should not be discounted.

“Ultimately the motivator here should not be about how we are seen; we need to ask … is Australia going to prosper in a world that is successfully acting on climate?

“With such a huge number of customers for thermal coal, metallurgical coal and natural gas, committing to net-zero emissions by 2050 and 2060, we have a lot of adjusting to do.”

A spokesman for Energy and Emissions Reduction Minister Angus Taylor said Australia is playing its part in the global response to climate change by meeting and beating our international commitments.

“As the PM has said: ‘Australia’s policies, when it comes to reducing emissions, are set here in Australia, in Australia’s national interests’. And our responsibility is to set that in a way that is consistent with the demands and needs and views of the Australian people and the science that supports that. And we have got a great track record.”

G.M. Will Sell Only Zero-Emission Vehicles By 2035

New York TimesNeal E. Boudette |

The move, one of the most ambitious in the auto industry, is a piece of a broader plan by the company to become carbon neutral by 2040.

The days of the internal combustion engine are numbered. General Motors said Thursday that it would phase out petroleum-powered cars and trucks and sell only vehicles that have zero tailpipe emissions by 2035, a seismic shift by one of the world’s largest automakers that makes billions of dollars today from gas-guzzling pickup trucks and sport utility vehicles.

The announcement is likely to put pressure on automakers around the world to make similar commitments. It could also embolden President Biden and other elected officials to push for even more aggressive policies to fight climate change. Leaders could point to G.M.’s decision as evidence that even big businesses have decided that it is time for the world to begin to transition away from fossil fuels that have powered the global economy for more than a century.

G.M.’s move is sure to roil the auto industry, which, between car and parts makers, employed about one million people in the United States in 2019, more than any other manufacturing sector by far. It will also have huge ramifications for the oil and gas sector, whose fortunes are closely tied to the internal combustion engine.

A rapid shift by the auto industry could lead to job losses and business failures in related areas. Electric cars don’t have transmissions or need oil changes, meaning conventional service stations will have to retool what they do. Electric vehicles also require fewer workers to make, putting traditional manufacturing jobs at risk. At the same time, the move to electric cars will spark a boom in areas like battery manufacturing, mining and charging stations.

Electric cars today are the fastest-growing segment of the auto industry, but they still make up a small proportion of new car sales: about 3 percent of the global total, according to the International Energy Agency. Sales of such cars jumped last year in Europe and China, but they remain niche products in the United States. They are bought primarily by affluent early adopters who are drawn to the luxury models made by Tesla, which dominates the business, and by environmentally conscious consumers.

A spokesman for Ford Motor declined to directly comment on G.M.’s move but said his company was “committed to leading the electric vehicle revolution in the areas where we are strong.” Several other automakers, most of them European, have previously pledged more modest steps in the direction that G.M. says it is headed. Daimler, which makes Mercedes-Benz cars, has said it would have an electric or hybrid version of each of its models by 2022, and Volkswagen has promised an electric version for each of its models by 2030.

G.M. said its decision to switch to electric cars was part of a broader plan to become carbon neutral by 2040. “General Motors is joining governments and companies around the globe working to establish a safer, greener and better world,” Mary T. Barra, G.M.’s chairman and chief executive, said in a statement. “We encourage others to follow suit and make a significant impact on our industry and on the economy as a whole.”

G.M.’s announcement comes just one week after Mr. Biden signed an executive order directing the Environmental Protection Agency and the Transportation Department to quickly reinstate tough auto fuel-economy rules put in place during the Obama administration, and one day after he signed a follow-up order directing the federal government to purchase all-electric vehicles. He is also pushing for a new economic recovery package to include funding to build 500,000 electric vehicle charging stations, and to create a system of rebates and incentives for purchasing electric vehicles.

On Thursday, a White House spokesman, Vedant Patel, welcomed G.M.’s new commitment. “We applaud efforts by the private sector to further embrace renewable and clean energy technologies,” he said. “As the president and many others have said, efforts like this will help grow our economy and create good-paying union jobs.”

G.M.’s move appears to follow a pattern by Ms. Barra of responding quickly to changes in the White House. It was Ms. Barra who, in the early days of the Trump administration, met with the new president in the Oval Office and asked him to roll back the tough Obama tailpipe pollution rules.

Four years later, her company’s evident about-face has won her the good will of those working to put those rules back in place.

“This move by G.M. is a big deal,” said Margo Oge, a former Obama administration official who played a lead role in developing the tough fuel economy standards and now informally advises the Biden administration and auto companies. “This helps the Biden-Harris administration to focus on long-term decarbonization of vehicles rather than just cleaning up the Trump mess.”

The chief executive of Audi, the luxury car company owned by Volkswagen, said customers would ultimately determine the speed of the transition to electric cars. “Ten years ago, nobody would have been able to foresee the enormous speed of change,” Markus Duesmann, the chief executive, who is also head of technology for Volkswagen, said in a statement.

Ferdinand Dudenhöffer, a veteran industry analyst, said that even if European carmakers had not put a date on internal combustion’s demise, there was a consensus that electric cars would dominate within 10 or 15 years. “Mary Barra is a good C.E.O.,” Mr. Dudenhöffer said. “She has the right strategy.”

Mr. Biden made clear on his first day in office that he intends to make tackling climate change one of the driving forces of his agenda. Chief among them are the federal standards on auto tailpipe pollution, which is the nation’s single largest source of heat-trapping greenhouse gases.

The Obama-era standards had required automakers to achieve an average of 54.5 miles per gallon by 2025, which would have eliminated about six billion tons of planet-warming carbon dioxide pollution over the lifetime of the vehicles, and required a large-scale transition to hybrid and electric vehicles. The Trump administration rolled back the standard to about 40 miles per gallon, essentially eliminating the need for companies to invest in such technology.

The Biden administration is expected to announce by April that it will introduce rules requiring cars to reach an average of about 51 miles per gallon by 2026. The proposal is also expected to include additional provisions aimed at boosting the production and sales of electric vehicles.

The American Petroleum Institute, which represents oil and gas companies, said automakers would do what they felt was right for their businesses. But the group’s senior vice president, Frank Macchiarola, said policymakers ought to protect the right of consumers “to choose what kind of car they want to drive.”

The vision of an all-electric future represents a dramatic shift in thinking at G.M. Just over 20 years ago, it developed an experimental electric car called the EV1 and leased it to a select group of customers. The car was praised by environmentalists. But seeing little profit potential in the EVI and American tastes shifting toward S.U.V.s, the automaker ended the effort. It even went so far as to take cars back from customers and destroy them, an episode chronicled in the documentary “Who Killed the Electric Car?”

G.M.’s reputation was further damaged in environmental circles in the 2000s as it produced larger and larger S.U.V.s. None engendered more scorn than the hulking Hummer H2, introduced in 2002. It weighed more than 6,600 pounds — twice the weight of a Honda Accord — and had a fuel economy of just 10 miles per gallon.

But by 2008, gas prices were rising and G.M.’s focus on trucks and S.U.V.s left it especially vulnerable just as the financial crisis hit. Its lack of fuel-efficient cars was a contributing factor in the troubles that led the company into a government-backed bankruptcy.

That history continues to dog G.M., and some experts said they were not convinced that the company would make the transition to electric cars as quickly as it had promised, in part because Ms. Barra or her successors could simply change their minds.

“To borrow a phrase from Thomas Edison, what consumers and the climate need are commitments that are 1 percent inspiration and 99 percent perspiration,” said David Friedman, a vice president of Consumer Reports. “Strong aspirations are important and inspirational, but firm production plans and strong policies are what move the market and the climate.”

But some in the environmental movement said they trust G.M. The company is working with the Environmental Defense Fund to develop a “shared vision” of leaving internal combustion vehicles behind. “E.D.F. and G.M. have had some important differences in the past, but this is a new day in America,” the group’s president, Fred Krupp, said in a statement.

G.M. said it would increase the use of renewable energy, and would eliminate or offset emissions from its factories, buildings, vehicles and other sources.

The company plans to spend $27 billion over the next five years to introduce 30 electric vehicles, including an electric Hummer pickup truck that it expects to start delivering to customers this year. Currently its main fully electric offering in the United States is the Chevy Bolt, a small car. The company sells several electric models in China.

“This is a guardedly bold move,” said Erik Gordon, a business professor at the University of Michigan who follows the auto industry. “It’s not that risky. Fifteen or 20 years from now, who knows where we might be? Mary Barra won’t even be C.E.O. But right now it’s hugely symbolic. This is very forward-looking.”

G.M. stock jumped after its announcement and closed up 3.5 percent, reflecting a growing consensus among investors that electric cars represent the future, and that Tesla and other electric carmakers will eventually dominate the auto industry, while businesses that do not make the transition to electric vehicles will do poorly.

Of course, even if G.M. and other automakers are able to move to an all-electric fleet by 2035 or 2040, combustion engine cars and trucks are likely to be on the roads for at least several decades to come in the absence of a huge government program designed to encourage people to replace them more quickly. There are more than 250 million vehicles on U.S. roads; the vast majority burn gasoline or diesel, and are on average about 11 years old.

(AU) Climate Change Puts Regional Communities At Risk, Better Regional Planning Needed: Experts

Domain -  Jack Needham

The risk of fires in Australia's south east is set to intensify, according to a new report. Photo: iStock

Regional communities anywhere near the bush are at increased risk of fire as the climate changes, and better planning is needed to avoid building in danger zones, experts warn.

A recent study found climate change made last year’s Black Summer bushfires worse, and predicted climate change would intensify the risk of similar events occurring in Australia’s south-east.

“There’s a whole range of ways that climate change is acting in south-east Australia to increase fire risk and that is something that will continue in the years ahead,” study lead author and ANU climate scientist Professor Nerilie Abrams told Domain. The review paper was published in the Communications, Earth and Environment journal.

Professor Abrams said communities located “anywhere near bush areas” would be at increased risk as a result.

“Those places are lovely to live in but there is an increased risk,” she said.

She warned Australians not to become complacent as a result of this year’s milder conditions following the devastation of the Black Summer bushfires.

“One of the takeaways from these studies is it would be very dangerous to write off what happened last summer as a freak, one-off event. This is a consequence of climate change and we would expect these events to become more frequent in the future.”

The comments come after a wave of city dwellers sought a tree-change during the pandemic, moving to regional towns in search of more space.

Stating that bushfires are something Australians will have to “learn to live with”, Professor Abrams said steps could be taken to improve community resilience, including the adoption of recommendations from the Bushfires Royal Commission, which handed down its final report in October 2020.

“[We should be doing] the type of things that we saw coming out of the royal commission into how we make our communities more resilient in the future,” she said.

“[That includes] planning as to where are the safe places to build new communities, looking at entry and exit points in communities – a major danger is communities with only a single entrance point.

“There’s a whole host of adaptions that we are going to need to put in place and improve from, making sure that people have bushfire survival plans, making sure they are bushfire ready and making sure that there isn’t fuel around the house.”

Andrew Gissing, general manager – resilience at risk management consultancy Risk Frontiers, said recent development trends meant an increasing number of Australians were likely living in areas of high bushfire risk.

“We’re building more and more into bushland. In a lot of ways it’s unavoidable because we have greater population,” Mr Gissing said.

He identified areas such as Macquarie Park and Ryde in Sydney as areas of the city where new development had seen urban areas encroach on bushland.

Proximity to bushland had been a key factor in whether homes were affected by fire during the NSW south coast fires in 2020, according to Mr Gissing.

He said 45 per cent of buildings destroyed during those fires were 10 metres from bushland and 80 per cent were within 100 metres of bushland.

But while “risk avoidance” was always preferable, Australia’s growing population meant that placing outright bans on development was unrealistic.

“As [the] population grows greater, there’s greater demand to accommodate [it] and greater pressure to develop into areas at risk,” he said.

“Sometimes people don’t necessarily have an option of whether they can live in a bushfire area or not.”

Instead, authorities should be doing more to ensure that new buildings – already built to stringent fire safety standards – remain compliant with building codes after their initial approval, as recommended by the Bushfires Royal Commission.

“For example, one of [the] conditions of approval may not have been to have wooden structures around the home but in later years when the home may have passed ownership, structures have been added,” he said.

“As a principle, we really need to ensure our building code measures are maintained over time.”

There are also steps homeowners in bushfire-prone areas can take to mitigate risk.

“Simple things like cleaning up the fuel [that] exists there, the vegetation around the home, making sure there’s space around the home [and] making sure that gas bottles are not located right on the side of the property,” Mr Gissing said.

(AU) Australia Needs To Stop Thinking That Setting A Target Of Zero Emissions By 2050 Is Good Enough

The Guardian

Political parties have to tell us what they are doing to keep within our carbon budget

We need to change how we talk about climate change policy. No longer can we hand out pass marks for irrelevant targets that sound good but actually fail to prevent climate change.

Back in 2018, the IPCC announced that we had 12 years to limit temperatures to 1.5C above pre-industrial levels.

This set off a lot of focus on different numbers: net zero by 2050 or 2045, 45% cuts by 2030 or 2035, 26% by 2030:


It’s no surprise that voters didn’t really grasp what is going on, because these targets actually disguise the reality of the task at hand and serve only to confuse.

Right now, the Morrison government remains wedded to a 26% cut in emissions from 2005 levels by 2030 and yet are on target for just 22%.

Before the last election the ALP pledged a 45% cut by 2030, but now is fudging because the government itself is unwilling to set a target beyond 2030 until after the next election.

Last year the talk was that the ALP would push the 45% cut out to 2035.

You can understand why voters tune out a bit – I mean is there much difference between 45% by 2030 or 2035, or between getting to zero by 2045 or 2050?

Yes there is – a massive difference.

And the reason is why a report last week by the Climate Targets Panel argues we need a 50% cut by 2030.

For, you see, the numbers we should focus on are not 2045 or 2050 but 6,161 and 3,521.

Or, to be precise: 6,161Gt C02-e and 3,521Gt C02-e.

These are the actual amount of carbon we can emit to keep temperatures below either 1.5C or 2C above pre-industrial levels.

The carbon emitted last year doesn’t get wiped away – it stays, adding to the impact of climate change.

Because we know the impact of carbon on temperatures, we can estimate how much more carbon can be emitted before there is too much in the atmosphere to prevent temperatures rising by certain amounts.

Research by Melbourne University climate scientist Malte Meinshausen done for the Victorian government estimates that Australia’s share of the global carbon budget is 6,161Gt C02-e in order to stay below a 2C increase, and 3,521Gt C02-e to stay below a 1.5C increase.

If we emit more than that we are contributing towards those higher temperatures.

This is the true vandalism of the Abbott-Turnbull-Morrison governments – their choices to increase emissions mean much greater cuts now are needed.

Think of it like a bank account.

Imagine you have $61,610 to last you for 30 weeks. That works out at $2,053 dollars to spend a week. But what if you spend $48,880 in the first 10 weeks?

Oops. You just used up 79% of your budget in a third of the time.

This is what we are currently projected to do with our carbon budget.

The latest government projections are for Australia to emit 4,880Gt C02-e in the 10 years to 2030.

If we keep on that path, we will use up all of our 2C budget of 6,161GT C02-e by 2033:


 And this is where the difference between those median-term targets matter.

Were the ALP to extend its median target of a 45% cut to 2035, that would actually be a pledge to use up all of our carbon budget by 2035.

A target of a 45% cut by 2035 is a target to fail.

The reason why the Carbon Target Panel argues we need a 50% cut by 2030 is because that trend will keep us from using up all of the 2C budget.

The bad news? Even that target will have us use up the carbon budget of 3,521GT C02-e we need to limit ourselves to limit temperatures below 1.5C.

The only way we can keep within the 1.5C budget it to target net zero emissions by 2035 – that would require cutting emissions by nearly three quarters by 2030:


The problem is that because emissions stay in the atmosphere, even if the government were to announce it will target net zero emissions by 2050, given how much will have been emitted by 2030 we will still go more than 50% over our carbon budget:


This is why, if Scott Morrison comes out and pledges getting to zero by 2050, no one should give him any credit whatsoever.

Unless he explains how he will do so and keep within our carbon budget, the pledge will be meaningless.

Currently if we want to do it in a nice straight line, we need to reach 50% cuts by 2030 and net zero by 2045.

That is the least disruptive timeline.

But if we keep on the current rate, so much of our budget will we have used by 2030 that we will need to slash emissions drastically and get to next zero by 2036:


A target of 45% cut by 2035 gives us no hope, and a target of 45% by 2030 means we would need to then get to zero by 2042.

So we need to stop thinking that setting a target of zero emissions by 2050 is good enough – we need to be asking what political parties are doing to keep within our carbon budget.

And if they don’t know, then we should treat their policies with the contempt they deserve.

(AU) Climate Change And Canberra’s Fossilised ‘Functional Realities’

Sydney Morning HeraldNick O'Malley

There was a telling moment bound up in an awkward pause during a parliamentary hearing on Friday into a climate change bill proposed by the independent MP Zali Steggall.

Liberal MP Trent Zimmerman asked a witness – Dr Angela Frimberger, a biologist turned climate activist – whether it was reasonable for a government to direct independent expert advisers to not provide them with advice that they did not want to hear and had no intention of acting upon.

The exchange was significant because in the unlikely event Steggall’s bill became law, it would legislate a net-zero emissions by 2050 target and create an independent climate change commission to provide the government with advice on how to reach that goal.

Zimmerman’s point was, should such a commission be created, why shouldn’t the government of the day order it not to provide advice over the reinstitution of a price on carbon, given neither party wanted to pursue such a policy?

“I would have thought it was not an unreasonable proposition to say that a government could indicate to a commission the parameters it was prepared to consider so [the commission] did not go down the path of providing advice that would have no functional reality in policy,” Zimmerman said.

Australia leading world with record renewable take-up, new data finds
In the pause that followed, you could hear the collective agony of the scientists who have begged politicians the world over for decades for meaningful climate action.

“But if carbon pricing was the most effective mechanism to achieve the outcome, then shouldn’t the government take advice from the independent body whose sole purpose is to provide that advice?” responded Frimberger after a beat or two.

“If the majority of the political spectrum has already made a determination that it is not prepared to go down that path, then it is meaningless in some ways,” said Zimmerman, ceding no ground.

Frimberger tried again: “But shouldn’t the majority of the political spectrum take expert advice?”

At this point the chairman stepped in and put the debate out of its misery, with Zimmerman presumably still certain of the primacy of “functional reality” and Frimberger still apparently more concerned with, well, reality.

Functional reality has retarded climate action in Australia – longer than it has in comparable nations – in large part because we create our wealth not just by the use of fossil fuel but by its export. But around the world, functional reality is being rapidly overwhelmed by climate reality.

Capital markets are abandoning fossil fuels and turning to green technology. Governments in Europe, Asia and now the United States are supercharging the shift with net-zero targets.

Last week the world’s largest investor, BlackRock, with more than $10 trillion in funds under management, reaffirmed that climate change and associated risk management would remain at the heart of its investment strategy.

Since then the London-based asset management group Aviva announced that not only would it divest from carbon-heavy businesses, it would no longer provide credit to them. It set a three-year timetable for companies to announce net-zero targets and strategies.

In an opinion piece published in the Financial Times over the weekend entitled Wall Street’s new mantra: green is good, the financial journalist and author Gillian Tett writes she has identified a significant shift in attitudes towards so-called environmental, social and governance (ESG) criteria – the standards companies set for their operations that can be tested and measured by the market.

Not long ago ESG was ring-fenced from general operations, used as a tool to signal good intentions to investor activists who wanted to change the world.

Morrison eyeing more ambitious climate target of net zero by 2050
Capital markets are abandoning fossil fuels and turning to green technology. Governments are supercharging the shift with net-zero targets.

Today, argues Tett, it is at the heart of operations, used by companies seeking to “avoid reputational risks, retain customers and employees, and sidestep losses”.

Tett quotes Anne Finucane, vice-chair of Bank of America, who estimates that of $US110 trillion in assets under professional management today, about 40 per cent have some sort of ESG consideration.

If green is now good according to global financial markets, how long will both parties back brown industries at the cost of rapid emissions reduction?

The support for Steggall’s bill suggests that, outside Parliament, the desire for rapid reductions is broad. It has been backed not just by groups such as the Clean Energy Council – which represents Australia’s renewable energy industry – but by the Australian Industry Group, the Business Council of Australia, the Planning Institute of Australia and the Property Council of Australia.

What's a 'just transition' and can you switch to green energy without sacking coal workers? 
This attitude is reflected in polls, such as that conducted by the Lowy Institute in 2019 which found that six in 10 Australians believed global warming is “a serious and pressing problem” about which “we should begin taking steps now even if this involves significant costs”.       

Despite this, both major parties remain home to supporters of old industries that scientists – and markets – believe must be abandoned.

Announcing a new climate spokesman in Chris Bowen, Labor plans to focus on the message that addressing climate change will prove to be a boon rather than a burden to the economy. It is betting that this message will be echoed in the markets too.

It is hoping that the functional reality – which is to say the political reality – and the scientific reality have finally converged.

Engineers Have Built Machines To Scrub CO₂ From The Air. But Will It Halt Climate Change?

The Conversation

Climeworks




Author
is Professor & ARC Future Fellow, University of Sydney. 
On Wednesday last week, the concentration of carbon dioxide in the atmosphere was measured at at 415 parts per million (ppm). The level is the highest in human history, and is growing each year.

Amid all the focus on emissions reduction, the Intergovernmental Panel on Climate Change (IPCC) says it will not be enough to avoid dangerous levels of global warming. The world must actively remove historical CO₂ already in the atmosphere - a process often described as “negative emissions”.

CO₂ removal can be done in two ways. The first is by enhancing carbon storage in natural ecosystems, such as planting more forests or storing more carbon in soil. The second is by using direct air capture (DAC) technology that strips CO₂ from the ambient air, then either stores it underground or turns it into products.

US research published last week suggested global warming could be slowed with an emergency deployment of a fleet of “CO₂ scrubbers” using DAC technology. However a wartime level of funding from government and business would be needed. So is direct air capture worth the time and money?

Direct air capture of CO2 will be needed to address climate change. Shutterstock

What’s DAC all about?

Direct air capture refers to any mechanical system capturing CO₂ from the atmosphere. Plants operating today use a liquid solvent or solid sorbent to separate CO₂ from other gases.

Swiss company Climeworks operates 15 direct air capture machines across Europe, comprising the world’s first commercial DAC system. The operation is powered by renewable geothermal energy or energy produced by burning waste.

The machines use a fan to draw air into a “collector”, inside which a selective filter captures CO₂. Once the filter is full, the collector is closed and the CO₂ is sequestered underground.

Canadian company Carbon Engineering uses giant fans to pull air into a tower-like structure. The air passes over a potassium hydroxide solution which chemically binds to the CO₂ molecules, and removes them from the air. The CO₂ is then concentrated, purified and compressed.

Captured CO₂ can be injected into the ground to extract oil, in some cases helping to counteract the emissions produced by burning the oil.

The proponents of the Climeworks and Carbon Engineering technology say their projects are set for large-scale investment and deployment in coming years. Globally, the potential market value of DAC technology could reach US$100bn by 2030, on some estimates.

Big challenges ahead

Direct air capture faces many hurdles and challenges before it can make a real dent in climate change.

DAC technology is currently expensive, relative to many alternative ways of capturing CO₂, but is expected to become cheaper as the technology scales up. The economic feasibility will be helped by the recent emergence of new carbon markets where negative emissions can be traded.

DAC machines process an enormous volume of air, and as such are very energy-intensive. In fact, research has suggested direct air capture machines could use a quarter of global energy in 2100. However new DAC methods being developed could cut the technology’s energy use.

While the challenges to direct air capture are great, the technology uses less land and water than other negative emissions technologies such as planting forests or storing CO₂ in soils or oceans.

DAC technology is also increasingly gaining the backing of big business. Microsoft, for example, last year included the technology in its carbon negative plan.

Opportunities for Australia

Australia is uniquely positioned to be a world leader in direct air capture. It boasts large areas of land not suitable for growing crops. It has ample sunlight, meaning there is great potential to host DAC facilities powered by solar energy. Australia also has some of the world’s best sites in which to “sequester” or store carbon in underground reservoirs.

Direct air capture is a relatively new concept in Australia. Australian company Southern Green Gas, as well as the CSIRO, are developing solar-powered DAC technologies. The SGG project, with which I am involved, involves modular units potentially deployed in large numbers, including close to sites where captured CO₂ can be used in oil recovery or permanently stored.

If DAC technology can overcome its hurdles, the benefits will extend beyond tackling climate change. It would create a new manufacturing sector and potentially re-employ workers displaced by the decline of fossil fuels.

Looking ahead

The urgency of removing CO₂ from the atmosphere seems like an enormous challenge. But not acting will bring far greater challenges: more climate and weather extremes, irreversible damage to biodiversity and ecosystems, species extinction and threats to health, food, water and economic growth.

DAC technology undoubtedly faces stiff headwinds. But with the right policy incentives and market drivers, it may be one of a suite of measures that start reversing climate change.

(AU) Net Zero, Saving Koalas And Forest Wars: The Crucial Environment Battles Looming In Australia

With the Morrison government looking increasingly isolated on climate policy and under pressure to fix conservation laws, will 2021 bring change?

The trainwreck of 2020 was not limited to a global community hit by the worst pandemic in a century. The Australian environment fared no better.

The year started amid the continent’s most widespread bushfires on record. As the Guardian revealed, an estimated 3bn animals were killed or affected. Subsequent major government reports outlined the extent to which the country’s unique environment was in decline long before the fires hit.

The damage from the fires could not be divorced from the climate crisis, which also triggered a third mass bleaching event on the Great Barrier Reef in five years.

But political debate on these pressing environmental issues – specifically, the need to transform conservation laws or introduce a climate plan to live up to the Paris climate agreement – remained stuck as the Morrison government resisted meaningful action on both fronts.

Will 2021 bring a change? Adam Morton and Lisa Cox look at some of the major climate and environmental questions the country will face this year.

Rising pressure to act on climate

Scott Morrison ended 2020 notably isolated on climate change, having been embarrassed when the British and French governments rejected his push to be given a speaking slot at a global leaders’ climate ambition summit.

The prime minister appeared surprised by the snub, which left him in climate pariah territory with the leaders of Saudi Arabia, Brazil and Russia.

If he was surprised, he shouldn’t have been: the invitation to the summit made clear only leaders offering substantial new commitments would be given a slot, and Morrison had merely flagged that Australia may not follow through on a widely condemned plan to use a carbon accounting sleight of hand to meet national emissions targets.

A major political and diplomatic question will be how the government responds to what is certain to be escalating pressure. The US will be key. The Biden administration has no shortage of problems needing its attention, but has made clear climate is near the top of its priorities.

The new president has pledged to use “every tool of American foreign policy to push the rest of the world” to do more. His climate envoy, John Kerry, set out the scale of the challenge for business leaders at a G20 forum, including that coal needed to be phased out five times faster than it is now.

More than 120 countries, including the major powers of America, Asia and Europe, have mid-century net zero emissions or carbon neutrality goals, but Morrison – despite calls and rising action from business leaders, investors and state governments – continues to resist, and deny that Australia is out of step.

The expectation is this can only last so long, but the message from the incoming US leadership and the climate ambition summit is that moving on the 2050 target alone will not be enough.

The focus ahead of the November climate conference in Glasgow will increasingly be on what Australia – with no meaningful policies to reduce emissions from transport or major industry and which is still promising a “gas-led recovery” and approving new coal projects – will do before 2030 to live up to the commitment it made in Paris five years ago.

Relying on the states to increase support for renewable energy, as many did last year, will not be enough.

Fixing failing environmental protection

In the wake of the fires, last year’s official assessment of the state of Australia’s natural environment by Graeme Samuel, the former competition watchdog chief, could hardly have been more dire.

An interim report in July found Australia’s environment was in an unsustainable state of decline, and that the national conservation laws – the Environment Protection and Biodiversity Conservation Act – were ineffective and needed substantial change.

Meanwhile, the auditor general’s office found the government and federal environment department were failing in their duty to protect nature.

Conservation groups were not surprised on either front. Australia has the world’s highest rate of mammal extinction due to what is widely agreed to be the failure of successive governments to protect the wildlife for which the country is renowned.

Funding for environment programs was cut by more than a third after the Coalition was elected in 2013. Some was restored last year, much of it directed to “congestion busting” – increasing the pace at which industry and business development proposals were assessed.

The government’s response was to try and fail to ram through legislation to transfer responsibility for approving major developments that affect the environment to the states and territories, barely giving lip service to the need to strengthen environmental protection.

It is still yet to release Samuel’s final report, which it has been sitting on since October. That will have to change when parliament returns next month if the government lives up to its legislative requirements. It is also expected to release the national environmental standards that Samuel said were needed to accompany the devolution in assessment powers to the states.

Several questions will follow. Will the standards be designed to not just maintain but improve the state of the Australian environment? Will they be specific enough that they can be meaningfully and legally tested?

And, given the government has rejected the push for an independent environment regulator, can the public be confident the new standards will be enforced?

Attention will also turn to whether the Senate crossbenchers will continue to oppose the government’s legislation if there are not steps to improve the monitoring and health of the country’s growing list of threatened species – at least 170 of which still have no plan for their recovery.

Will the Great Barrier Reef bleach again?

Australia’s most globally recognisable natural landmark suffered through its third major coral bleaching event since 2016 last year. Most of the damage was near the southern end around Mackay – an area that was mostly left untouched in 2016 and 2017. It means reefs along the full length of the 2,300km wonder have been severely affected over the past five years.

There are still healthy and vibrant areas and some damaged coral will recover, but a significant amount of shallow water coral died.

As recently as a few weeks ago, there were concerns this summer might be a fourth year of severe bleaching out of six. But Prof Terry Hughes, from James Cook University, says the risk has reduced since Christmas thanks to cooler, cloudier and wetter weather, in part due to the cooling La Nina over the Pacific.

An assessment by the US National Oceanic and Atmospheric Administration suggests the risk of bleaching is greatest north of Cairns, and a warmer than expected February could still change projections, but Hughes says the chance of a non-bleaching year is “pretty good”.

It is a less positive story in the west. The CSIRO has forecast a marine heatwave for the Western Australian coastline early this year, with temperatures expected to hit the highest level in a decade.

The Ningaloo Coast and Shark Bay, both world heritage listed areas, are threatened by warming ocean temperatures that could affect ecosystems and fisheries that have not recovered since a marine heatwave in 2011.

Saving the Koala

The capriciousness of New South Wales politics was on full display last year when the deputy premier, John Barilaro, threatened, but failed to resign ostensibly over a policy designed to protect koalas, just months after the iconic species was devastated by the summer bushfires.

A compromise deal between the governing Liberal and National parties over the koala state environmental planning policy failed. Instead, NSW reverted to an old koala policy, from 1995, with a promise to develop a new one this year.

It meant that, despite a state inquiry finding the species was on track for extinction in NSW by 2050, nothing new has been done to improve its protection.

Whether that can be addressed will be a test for both state and federal governments. It is linked to the broader issue of ongoing habitat destruction, one of the main threats to not just the koala, but Australian wildlife generally.

Sussan Ley, the federal environment minister, has set an October deadline for the threatened species scientific committee to assess whether east coast koala populations have been affected enough to warrant a national endangered listing – a step that should trigger greater protection.

Meanwhile, the government continues to sanction clearing of the forests that koalas rely on. Late last year Ley approved a quarry proposal that would clear 50 hectares of koala habitat near Port Stephens in NSW.

It is a similar story at state level. The NSW environment minister, Matt Kean, has set a target to double the state’s koala population by 2050, but forestry operations and mining proposals in koala and other threatened species’ habitat continue, and the state government has continued to weaken land-clearing laws.

Stalling on electric vehicles

Analysts say the shift to EVs is inevitable, with new models forecast to match fossil fuel vehicles on price by as early as 2025, but Australia trails other countries in their uptake, with fewer affordable models available.

A long-delayed Morrison government electric vehicle policy – now rebadged as a broader “future fuels” strategy – was due late last year, but has yet to be released. A leaked draft suggests it will not include direct incentives for consumers to switch to battery-powered cars.

Other countries have seen a climate and economic advantage in moving now. Britain and Japan – major countries that, like Australia, use right-hand-side drive cars – announced late last year they would ban the sale of new petrol cars by 2030 and 2035 respectively and introduce incentives to drive the change.

Australia appears headed in the other direction with no significant incentives, and with some states planning to introduce road-user charges on EVs and hybrids. Victoria and South Australia are heading down this path, and NSW is considering it.

Academic analysis has suggested this would further deter uptake of the technology unless offset by other support. Meanwhile, national transport emissions continue to rise.

The forest wars (redux)

Court decisions loom large over native forest logging in two Australian states this year, and an industry that spent much of last year under siege.

A judgment is due next month in a case brought by the Bob Brown Foundation against Tasmania’s state-owned forestry agency, arguing its native forest logging is inconsistent with federal laws. Conservationists argue the forest agreement in the state is not valid as it lacks a legally enforceable requirement that the state protect threatened species.

It follows a similar case in Victoria last year, when a federal court judgment banned logging in 67 coupes in Victoria’s central highlands on the basis that the state’s agency, VicForests, had breached a regional forestry agreement between the state government and Canberra.

In basic terms, the ruling challenged a controversial effective exemption from environmental laws granted to logging under the agreement. The agency is appealing.

Major retailers are increasingly refusing to sell paper logged by agencies without forest stewardship council, or FSC, certification - and both the Tasmanian and the Victorian agencies have failed to get it.

It means the court decisions could have significant ramifications for plans to continue native forest logging at current levels until 2030, in Victoria’s case, or indefinitely in Tasmania. And they could have major ramifications for threatened species protection.
