Q&A: How can Australia achieve climate change net-zero emissions by 2050 or earlier? - Lethal Heating Editor BDA

Key Points
Australia aims to reach net-zero greenhouse gas emissions by 2050 or sooner, and the Federal Government has outlined priorities to achieve this goal.

The plan emphasises clean electricity, electrification and efficiency, an expansion of clean fuels, investment in new technologies, and scaled carbon removals. [1]

Every sector of the economy will need to reduce emissions quickly, including electricity, transport, buildings, industry, and agriculture. [2]

The task requires coordinated action by federal and state governments, local councils, business, investors, communities, and households. [3]

Success depends on clear policy signals, streamlined planning and approvals, stronger industrial strategy and public finance that leverages private capital. [6]

Households and firms must adopt electric vehicles, heat pumps, rooftop solar, efficient appliances and lower-carbon diets and supply chains. [4]

Scientific and economic modelling shows delaying action increases long-term costs and the risk of more extreme climate impacts. [2]

Practical examples from councils, regional projects and public finance bodies show that rapid progress is feasible when regulation and investment align. [6]

Failing to meet net-zero by 2050 would increase damage from heat, fire, flood, and drought and create economic and social costs that are far higher than the price of early action. [5]

Why net zero by 2050 matters

Net zero means balancing greenhouse gases emitted with removals, so the net increase in atmospheric greenhouse gases is zero.

Scientists and policy bodies say net-zero is essential to limit warming and avoid the worst physical and economic impacts of climate change. [2]

Every year of delay adds cumulative carbon to the atmosphere and makes stabilisation harder and more expensive.

Failing to achieve net-zero by mid-century increases the frequency and severity of heatwaves, fire weather, floods, and droughts in Australia.

The cost of inaction shows up in damaged infrastructure, disrupted supply chains, rising insurance costs, and pressure on health and emergency services. [5]

It also risks stranded fossil-fuel assets and lost opportunities in growing global markets for low-carbon exports such as green metals and hydrogen. [6]

National and government action

The Climate Change Act 2022 provides the legislative foundation for Australia’s emissions targets and annual reporting obligations. [3]

In 2025 the Federal Government set a stronger near-term target and outlined a Net Zero Plan that organises effort around five decarbonisation priorities. [1]

Key domestic levers include tightening the Safeguard Mechanism, accelerating grid connection approvals and reforming planning to speed deployment of renewable generation and transmission. [2]

Tax incentives and production credits for critical minerals and renewable hydrogen are designed to anchor supply chains and attract investment. [6]

Public finance vehicles such as the Clean Energy Finance Corporation are already mobilising large capital commitments to deliver projects and unlock private funding. [4]

Sectoral change and who must act

  • Electricity: the grid must move to near-100 per cent low-emissions generation supported by storage, demand response and better interconnection. [2]
    That requires transmission upgrades, reform of market design and faster approvals for large-scale renewables and long-duration storage. [2]
  • Transport: light-vehicle fleets must electrify rapidly and governments must build charging infrastructure and tighten fuel efficiency rules. [2]
    Freight, shipping, and aviation need low-carbon fuels and efficiency improvements and pathfinding policies for hydrogen and sustainable aviation fuels. [6]
  • Buildings: new homes and commercial buildings should be zero-emissions-ready and existing buildings must be retrofitted with insulation, electric heating and induction cooking. [2]
    Regulation, targeted subsidies and consumer incentives will be necessary to lift retrofit rates at scale.
  • Industry: heavy industry requires low-carbon process heat, hydrogen and carbon-capture where necessary, alongside circular materials strategies. [2]
    Industrial clusters located near cheap renewable energy or hydrogen supply will lower costs and speed deployment. [6]
  • Agriculture and land: farmers can reduce methane and nitrous oxide emissions through feed, fertiliser, and manure practices and expand on-farm carbon storage through reforestation and soils. [2]

Australian case studies and evidence

The Climate Change Authority’s Sector Pathways Review compiles sector-by-sector options and shows feasible routes to net-zero with current and near-term technologies. [2]

CSIRO’s pathway modelling provides technical scenarios and demonstrates that rapid decarbonisation is technically feasible if policy and investment align. [3]

The Clean Energy Finance Corporation reported record commitments and shows public finance can mobilise private capital at scale when policy signals are clear. [4]

Media reporting and independent analysis from 2025 record the government’s higher near-term targets and the policy measures intended to meet them. [1]

Challenges and the path ahead

Major obstacles include grid congestion, planning and approval delays, workforce shortages and the higher upfront cost of some clean technologies. [2]

Coordinated governance across federal, state and local levels is difficult but essential for efficient rollout and avoiding regulatory whiplash.

A carefully managed just transition is required for workers and regions dependent on fossil fuels, and that requires retraining, targeted investment and clear regional development plans. [4]

Early and well sequenced policy reduces the risk of locking in high-emissions infrastructure and lowers the long-run cost of transition. [2]

Consequences of failure and urgency

Failing to reach net-zero by 2050 increases the likelihood of more severe climate extremes and raises long-term adaptation costs for governments and households. [5]

Economic consequences include stranded assets, higher insurance premiums, disrupted industries and weaker performance in emerging low-carbon export markets. [6]

By contrast, a credible, well governed transition can create jobs, attract investment and sustain Australia’s economic competitiveness in a decarbonising global economy. [4]

Q&A: How can Australia prepare for more frequent and severe natural disasters linked to climate change? - Lethal Heating Editor BDA

Key Points
  • Australia faces more frequent heatwaves, bushfires, floods, droughts, cyclones, and coastal inundation.[1]
  • Vulnerable groups include the elderly, remote and low-income communities, First Nations people, and coastal populations.[2]
  • Recent case studies: the Black Summer bushfires and the 2022 Northern Rivers floods.[3]
  • Preparation must combine mitigation (emissions cuts) and adaptation (early warning, resilient infrastructure).[4]
  • Safeguarding requires land management, insurance reform, community training, habitat corridors and species migration planning.[5]

Australia Faces a Rising Wave of Climate-Driven Natural Disasters

Australia is already experiencing a rising burden of severe natural disasters driven by climate change.

Heatwaves, bushfires, floods, droughts and coastal inundation are intensifying in both frequency and severity.

Those in remote regions, older age brackets, First Nations communities and low-income coastal towns are most exposed.

Recent events such as the 2019–20 Black Summer bushfires and the 2022 Northern Rivers floods show the urgent need for concerted adaptation.

National and local strategies must combine emissions reductions, early warning systems, resilient design, ecological resilience and social equity.

Types and Frequency of Major Disasters

Australia faces several disaster types that climate change is amplifying.

Heatwaves are becoming more frequent, lasting longer, and reaching higher peak temperatures.[6]

The State of the Climate report says Australia has seen an increase in extreme heat events over land and ocean.[6]

A recent study estimated that between 2016 and 2019 heatwaves caused 1,009 deaths in Australia.[7]

Bushfires are worsening.[1]

Climate change leads to more “dangerous fire weather days” and longer fire seasons, especially in southern and eastern Australia.[1]

In the Black Summer 2019–20, over 24 million hectares burned and more than 3,000 homes were lost.[1]

Floods and heavy rainfall events are intensifying.[1]

Warmer air holds more moisture, so storms release more rain in concentrated bursts.[1]

Recent east coast lows, for example in June–July 2025, caused flooding across parts of New South Wales.[8]

Droughts and dry conditions are projected to become more common in many regions, especially the south and east.[1]

Tropical cyclones are not expected to become more frequent overall, but a larger share may reach high intensities.[1]

Coastal inundation and sea level rise will exacerbate storm surges and land loss.[1]

Vulnerable Areas and Populations

Some places and people face much greater risks than others.

Coastal zones and low-lying areas are vulnerable to sea-level rise, storm surge, erosion and saltwater intrusion.[9]

Rural and remote communities with limited access to services face heightened exposure to fire, flood isolation, and heat stress.[2]

Older adults, people with chronic illnesses, children, those on low incomes, and socially isolated residents are more vulnerable during extreme events.[2]

Biodiversity and ecosystems also face uneven threat.[10]

Bushfire “mega-studies” link the 2019–20 fires to dramatic wildlife loss and habitat collapse.[10]

Coral reef systems, such as the Great Barrier Reef, suffer from repeated bleaching triggered by marine heatwaves.[11]

Recent Case Studies

The Black Summer bushfires (2019–20) remain a stark example of climate-intensified disaster.[3]

They burned more than 24 million hectares, destroyed thousands of properties and killed or injured many, including wildlife.[3]

The 2022 Northern Rivers floods in New South Wales marked one of Australia’s costliest disasters.[1]

Multiple river systems overflowed, lives were lost, infrastructure was wrecked, and recovery stretched for years.[1]

How to Prepare — Safeguarding People, Property and Nature

  • Australia needs both mitigation (cutting emissions) and adaptation (adjusting to change).[4]
  • Without strong emissions reductions, dangers will accelerate.[4]
  • Early warning systems and forecasting must improve.[12]
  • Land and fuel management is vital.[5]
  • Resilient infrastructure and building codes must evolve.[7]
  • Ecosystem protection and restoration matter.[10]
  • Insurance and economic policies must be reformed.[13]
  • Community engagement and equity must guide adaptation.[13]
  • Animal and plant protection approaches include wildlife rescue networks, seed banking, captive breeding and habitat corridors.[10]
  • Monitoring, research, and iterative learning are essential.[14]

Conclusion

Australia faces a rising toll from climate-driven disasters: heatwaves, bushfires, floods, droughts, cyclones and coastal inundation.[1]

Those in remote, coastal and marginal areas—especially older, lower-income and First Nations communities—are most exposed.[2]

The Black Summer bushfires and the Northern Rivers floods show the damage is already underway.[3]

Australia must act decisively: cut emissions, build resilient systems, protect ecosystems and empower communities.[4]

Only through integrated, equitable adaptation and mitigation can the nation safeguard its people, economy, and biodiversity in a hotter world.

Q&A: What health issues are linked to climate change in Australia, and which populations are most vulnerable? - Lethal Heating Editor BDA

Key Points
  • Extreme heat, bushfires, and floods are now the leading climate-linked threats to health. [1]
  • Respiratory problems and heart disease spikes have been recorded after major climate disasters. [3]
  • Climate change spreads mosquito-borne and exotic diseases into new areas. [9]
  • Young people, elderly, Indigenous Australians, those in poverty or with chronic conditions are most at risk. [5]
  • Urgent action is needed to modernise healthcare, adapt communities, and reduce emissions. [2]

Australia faces a growing public health crisis as climate change intensifies heatwaves, worsens air quality, spreads new diseases, and leaves increasing numbers of people shaken by disaster and stress.

Rising temperatures and extreme weather events are already leading to more heat-related and respiratory illnesses, with lasting consequences for mental health.​

The most at-risk groups include older adults, children, Indigenous Australians, low-income households, and those with pre-existing medical conditions.​

Case studies since 2020 reveal sharp increases in hospital visits during heatwaves and bushfires, and scientific data show urgent adaptation and healthcare reforms are needed.​

Tackling these health risks demands rapid action across all sectors to build resilience, support vulnerable communities, and cut greenhouse gas emissions.​

Extreme Heat and Heat-related Illnesses

Australia has warmed by over 1.5°C since 1910, with heatwaves becoming longer, more frequent, and more severe.[4]

Heat kills more Australians than any other natural disaster, and at least 49,000 years of healthy life are lost annually to cardiovascular disease triggered by hot weather.[6]

Recent modelling shows the number of deaths associated with heat-exacerbated heart disease could double or triple by 2050 if global warming trends persist.[6]

Children, older adults, outdoor workers, and people with chronic medical issues face particular danger during heatwaves.[5]

The “urban heat island” effect amplifies risk in major cities, where nights often fail to cool down and air pollution worsens.[5]

Respiratory Conditions and Air Quality

Climate change drives more frequent and intense bushfires, producing smoke that chokes cities for weeks.[3]

During the 2019–2020 “Black Summer” bushfires, an estimated 417 excess deaths and over 3,000 cardiovascular-related hospital admissions were linked to smoke exposure.[3]

Asthma and hay fever attacks also spike, owing to increased pollen release during hotter, longer springs and bushfire smoke.[7]

People with asthma, lung disease, heart conditions, and children are most susceptible.[5]

Mental Health Impacts

Extreme heat and disasters take a mounting toll on Australians’ mental wellbeing.[8]

Research finds nearly half of the mental and behavioural disorder burden by 2050 could stem from higher temperatures alone.[8]

Young people are particularly vulnerable, especially those exposed to climate disasters or who already experience financial hardship.[11]

Post-traumatic stress disorder, depression, and anxiety rise in disaster-hit areas, while many report a sense of climate-related distress and loss.[12]

Vector-borne and Infectious Diseases

Rising temperatures and shifting weather patterns allow disease-carrying mosquitoes and exotic viruses to thrive further south and for longer periods.[9]

Recent outbreaks of Japanese encephalitis, which caused several deaths in 2022, underline growing risks linked to changing bird migration and mosquito ranges.[9]

Experts warn other diseases, such as those spread by bats or other insects, may follow as climate disruptions intensify.[9]

Disproportionate Impact on Vulnerable Populations

Older adults, children, people with disabilities, pregnant women, Aboriginal and Torres Strait Islander peoples, and those living in poverty or rural and remote areas are at the highest risk.[5]

Communities with fewer resources, such as limited cooling, inadequate housing, or less access to medical care, often suffer far greater health impacts during and after disasters.[10]

Australians: Here is Climate Change Action We All Can Take - Lethal Heating Editor BDA

Key Points
  • Australians of all ages can take climate action suited to their stage of life[1]
  • Practical steps include clean energy, sustainable transport, ethical investment, and civic advocacy[2]
  • Community and intergenerational collaboration amplify impact and resilience[3]

All Australians can act on climate change in ways that fit our lives and values.

Climate change affects everyone, but the way we respond can depend on our stage of life, resources, and influence.

From students to retirees, Australians can act together to reduce emissions, protect the environment, and strengthen community resilience.

Students: Learning, Leading, and Inspiring

Young Australians are already at the forefront of climate activism and education.

Students can push for climate literacy in schools, join sustainability clubs, and participate in youth climate movements.[1]

They can encourage their schools to install solar panels, switch to renewable electricity providers, and promote waste reduction programs.[2]

Even simple changes such as walking, cycling, or using public transport to get to school reduce emissions and set powerful examples for others.[3]

Young Adults: Choosing Sustainable Lifestyles

For Australians in their 20s and 30s, lifestyle choices can make a big impact.

Opting for low-carbon diets, avoiding fast fashion, and minimising car use are effective ways to shrink personal footprints.[4]

Renters can choose energy-efficient appliances and ask landlords about insulation and renewable energy options.[5]

Supporting ethical banks and super funds that divest from fossil fuels will channel money toward clean industries and sustainable growth.[6]

Parents and Families: Building Habits and Hope

Parents hold unique power to influence future generations through their choices and conversations.

Teaching children about energy use, biodiversity, and climate science builds awareness and action.[7]

Families can adopt low-waste lifestyles, grow food in home or community gardens, and invest in home efficiency upgrades.[8]

Collective actions, like joining local environmental groups or advocating for school solar programs, strengthen communities while lowering emissions.[9]

Homeowners: Cutting Energy and Costs

Homeowners have opportunities to reduce emissions through energy upgrades and smart design.

Installing rooftop solar, battery storage, and efficient heat pumps can slash household emissions by up to 70 per cent.[10]

Upgrading insulation, draught-proofing, and LED lighting delivers immediate savings while improving comfort.[11]

Rebates and incentives through programs like the Federal Home Energy Upgrade Fund make these improvements more accessible.[12]

Workers and Business Owners: Driving Change in the Economy

Australia’s workforce can help accelerate the transition to a low-carbon economy.

Workers can push employers to adopt sustainability targets, switch to renewable power, and reduce waste.[13]

Small businesses can cut costs and attract customers by adopting green certifications or carbon-neutral practices.[14]

Choosing suppliers with strong environmental standards magnifies the impact across supply chains.[15]

Community Members: Acting Locally

Neighbourhood and community initiatives can scale up climate action rapidly.

Participating in local sustainability groups or tree-planting events builds resilience and solidarity.[16]

Advocating for better public transport, bike lanes, and local renewable projects ensures equitable and long-term benefits.[17]

Community energy cooperatives, like Hepburn Wind in Victoria, show how citizens can own and profit from clean energy.[18]

Retirees: Legacy and Mentorship

Older Australians can combine wisdom and financial influence to help shape a sustainable legacy.

Retirees can install energy-efficient systems, support local conservation efforts, and advocate for climate-aware policy.[19]

Investing retirement savings in ethical funds and mentoring younger activists amplifies impact across generations.[20]

Many retirees also volunteer with Landcare or community gardens, helping restore ecosystems and community spirit.[21]

Policy Engagement: Voices That Matter

Individual action gains strength when paired with civic participation.

Australians of all ages can write to MPs, attend town meetings, and vote for policies supporting renewable energy and environmental protection.[22]

Grassroots advocacy has repeatedly influenced national energy policy and helped secure stronger emissions targets.[23]

Democracy and climate action are deeply linked, and every voice adds weight to the call for change.[24]

Australia Braces for a Summer of Climate Extremes - Lethal Heating Editor BDA

Key Points
  • Above-average temperatures forecast across much of Australia.[1]
  • High fire danger warnings in southern/eastern states.[2]
  • Flooding risk persists for eastern regions.[4]
  • Insurance losses due to extreme weather among world’s highest.[3]
  • Community and government adaptation crucial for resilience.[5]

The coming Australian summer is forecast to bring above-average temperatures, worrying fire weather, and a complex mix of heavy rain and dry spells in different regions.[1]

Communities across eastern and southern Australia should brace for hotter days and heightened risks, especially in fire-prone areas, while selected eastern regions see an increased chance of flooding.[2]

Economists, ecologists, and sociologists warn of far-reaching social, economic, and ecological disruptions, with insurance claims and government expenditure on disaster response forecast to rise sharply.[3]

Australian culture faces another season of adapting: heatwaves will change community events, disrupt festivals and sports, and place new stress on vulnerable groups.[4]

Policymakers are being urged to ramp up climate mitigation strategies, including emergency planning, green infrastructure, and community education.[5]

Temperature and Heatwaves: Forecasts and Risks

Daytime temperatures are forecast to be above average for most of the continent outside parts of coastal New South Wales.[1]

Maximum temperatures are likely to surpass historical averages by 1-4°C in many areas, with Victoria and Tasmania facing the highest chances of unusual heat events.[1]

Multiple days above 35°C will be common in the southern and eastern interiors, while humid heatwaves may afflict Darwin and northern regions.[2]

Heatwaves are expected to last longer than in previous years, putting pressure on vulnerable Australians, especially elderly populations in major cities and remote communities.[4]

Public health warnings have already been issued, urging people to monitor for dehydration, heat stress, and respiratory problems.[2]

Fire Weather: Escalating Dangers

Fire danger warnings have been declared early, especially in southern and eastern Australia, where warm and dry conditions will align with strong winds.[2]

The Bureau of Meteorology’s forecast points to heightened fire risks for the Greater Sydney region and much of Queensland, with bans and emergency response teams already on standby.[2]

While some parts of eastern Australia may see more rain, brief dry spells and intensifying heat can rapidly elevate bushfire danger even in normally wet regions.[1]

Climate projections suggest bushfires could become more intense and erratic, with fire seasons starting earlier and lasting longer over the coming years.[4]

Rainfall Patterns: A Mixed Picture

Rainfall outlooks remain complex, with the possibility of above-average rain for much of the southeast and northeast—as much as 60-80% above median in some regions—while other areas have equal chances of dry or wet conditions.[1]

Heavy storms and tropical weather are anticipated to peak in January to March, which could bring flash flooding and disruptions to transport and agriculture.[4]

Recent shifts in the Indian Ocean Dipole and La Niña climate patterns influence forecasts, with uncertainty over how ocean temperatures may amplify extremes.[1]

Social and Economic Impacts

Extreme heat and volatile weather will place additional strain on health systems and emergency response services, especially in regional communities.[2]

Rising insurance costs, home repairs, and crop losses represent significant economic threats, with Australia ranking among the world’s highest for per capita weather-related insurance claims.[3]

Remote and Indigenous communities face unique cultural and social disruptions, including lost land and interrupted traditional events due to floods or fires.[4]

Ecological and Cultural Impacts

Warming conditions endanger native wildlife, with heat stress, shifting migration patterns, and habitat loss threatening struggling species such as koalas, bandicoots, and numerous birds.[4]

Coral bleaching risk rises as elevated sea surface temperatures persist along the coast, particularly following the record-breaking ocean heat now observed in the region.[1]

Australian cultural life—festivals, sports, and family gatherings—will adapt in response to extreme heat, with cooling spaces, altered schedules, and new health safety measures becoming the norm.[4]

Political Actions and Required Mitigation

Governments and local councils are encouraged to intensify efforts to protect communities from climate impacts this summer.[5]

Important strategies include strengthening emergency management, updating fire response plans, building green infrastructure, and increasing community engagement on heat awareness.[2]

Individual actions—staying informed through official sources, preparing emergency kits, supporting vulnerable neighbours—will be crucial in boosting local resilience.[5]

Conclusion: Adapting for a Safer Future

Australia faces a challenging summer marked by rising heat, serious fire risks, uncertain rainfall, and evolving climate realities.[1]

Through collective action and government leadership, there is potential to buffer communities and ecosystems against the worst impacts, and lay the groundwork for long-term climate resilience.[5]

Queenstown Tasmania 2050: A Mining Town Faces the Heat of Climate Change - Lethal Heating Editor BDA


Key Points
  • Queenstown projected to warm by 1.6°C to 2.9°C by 2050[1]
  • Increased frequency and severity of heatwaves predicted[2]
  • Fire danger season expected to lengthen and intensify[5]
  • Winter rainfall up, summer rainfall down after 2050[6]
  • Policies by 2025 focused on adaptation, but stronger action required[3]

Climate Change Shifting Queenstown’s Future

Queenstown, Tasmania, is bracing for a climate-altered future shaped by more extreme weather, social adaptation, and shifting economic prospects. 

Rising temperatures, intensifying heatwaves, and an evolving rainfall pattern are forecast to transform life in this rugged mining town by the middle of the century.[1]

Scientific models indicate that Queenstown and its surrounds will experience hotter days, longer fire danger seasons, and more pronounced changes in when and how rain falls.[2]

The local government’s climate response, shaped by recent statewide plans, is attempting to shore up resilience and reduce emissions.

However, experts warn that more dramatic action is needed to protect livelihoods and landscapes.[3]

From economic risks to cultural shifts, the impacts of climate change will touch every aspect of Queenstown’s community.[4]

Rising Temperatures and Heatwaves

By 2050, Queenstown is expected to be warmer by at least 1.6°C under a low-emissions scenario and up to 2.9°C if global emissions track current trends.[1]

This warming will result in hotter summers and milder winters, with average daily minimum temperatures rising faster than daily maximums.[1]

Heatwaves—extended periods of high temperatures—will be more frequent and last longer, raising health risks for older residents and children.[2]

Tasmanian models suggest that days over 35°C could double in some regions, impacting outdoor work, sports, and tourism.[2]

Shifting Rainfall Patterns

Climate forecasts for Queenstown and Tasmania’s west show total annual rainfall may not change dramatically, but its distribution will.[1]

Winter rainfall is projected to increase significantly, while summer rainfall is set to decline after 2050.[6]

This seasonal imbalance will challenge water resource management and could affect local agriculture and wilderness ecosystems.[7]

Less summer rain and higher evaporation rates could exacerbate periods of drought and stress the region’s forests and rivers.[1]

Intensifying Fire Weather

Queenstown’s fire danger season, already a concern in remote western Tasmania, is forecast to lengthen and intensify.[5]

Spring and summer will see more days classified as “high fire danger,” driven by warmer temperatures, lower humidity, and shifting wind patterns.[5]

This raises the likelihood of total fire bans and creates operational challenges for local emergency services.[5]

Ecologically, bushfires pose a threat to World Heritage areas and endangered species, altering habitats and community structure.[5]

Socially, repeated evacuations and property risk may increase community anxiety and stress.[5]

Economic and Social Impacts

Queenstown’s economy, which is strongly linked to mining, small-scale agriculture, and eco-tourism, faces emerging strain from climate change.[8]

Reduced summer rainfall and more frequent fires could disrupt tourism, damage infrastructure, and affect mining operations reliant on water.[7]

Higher temperatures and changing rainfall will force local farms to adapt crops and livestock, requiring new technology and investment.[7]

Socially, increased heatwaves and emergencies may strain local health systems, demand new community support structures, and challenge vulnerable residents.[5]

Cultural and Ecological Change

Ecologically, Queenstown’s forests and rivers, already recovering from mining’s legacy, are vulnerable to temperature-driven stress and altered rainfall.[1]

More frequent fires and invasions of new pests and weeds could dramatically change local flora and fauna.[5]

Cultural heritage, including Indigenous connections to land, faces disruption as traditional practices must adapt to changing conditions.[9]

Community events, outdoor recreation, and tourism will also need to adjust to more unpredictable and extreme weather.[4]

2025 Policy Action vs. 2050 Needs

The Tasmanian government’s 2023–25 Climate Change Action Plan prioritises resilience, emissions reduction, research, and adaptation grants.[3]

Measures include emissions cuts, support for clean transport, and updating regional climate models.[10]

Yet, climate experts argue these steps must be rapidly scaled up to match the projections for Queenstown by 2050, with deep emission cuts, stronger community preparedness, infrastructure upgrades, and safeguarding natural assets becoming essential.[11]

Without more ambitious action, projected impacts may overwhelm available resources and threaten long-term sustainability.[3]

Conclusion: Future at a Crossroads

By 2050, climate change will reshape Queenstown’s weather, the economy, landscape, and social fabric.[1]

The community’s ability to adapt through strengthened policies, grassroots action, and innovation will determine whether challenges become opportunities.[4]

A focused, collective push to cut emissions and boost resilience will help Queenstown weather the coming storm.[3]

The decisions made today set the trajectory for the next generation.[4]

The 2025 EAT-Lancet Commission on healthy, sustainable, and just food systems presents new evidence-based insights on nutrition and human health, within safe and just planetary boundaries. 
New to this Commission are updates to the planetary health diet, measurement and assessment of the impact food systems have in driving transgressions of planetary boundaries, an exploration of multi-dimensional and underlying issues of food justice, new research and extensive modelling insights, and transformative and action-based recommendations and roadmaps.
The Commission lays the foundations for food systems to take a central role in the post-SDG era, presenting global, regional, local, and individual means to achieve that while creating and retaining a just social foundation, that protects human health and minimises harms to planetary health.
Adoption of a plant-rich “planetary health diet” could prevent 40,000 early deaths a day across the world, according to a landmark report.

The diet – which allows moderate meat consumption – and related measures would also slash the food-related emissions driving global heating by half by 2050. 

Today, a third of greenhouse gas emissions come from the global food system and taming the climate crisis is impossible without changing how the world eats, the researchers said.  

Food production is also the biggest cause of the destruction of wildlife and forests and the pollution of water.

The planetary health diet (PHD) sets out how the world can simultaneously improve the health of people and the planet, and provide enough food for an expected global population of 9.6 billion people by 2050.

The diet is flexible, allowing it to be adapted to local tastes, and can include some animal products or be vegetarian or vegan. 

However, all versions advise eating more vegetables, fruits, nuts, legumes and whole grains than most people in the world currently eat. In many places, today’s diets are unhealthy and unsustainable due to too much meat, milk and cheese, animal fats and sugar.

People in the US and Canada eat more than seven times the PHD’s recommended amount of red meat, while it is five times more in Europe and Latin America, and four times more in China. However, in some regions where people’s diets are heavily reliant on starchy foods, such as sub-Saharan Africa, a small increase in chicken, dairy and eggs would be beneficial to health, the report found.

Severe inequalities in the food system must also be ended to achieve healthy and sustainable diets, the researchers said. The wealthiest 30% of the world’s population generates more than 70% of food-related environmental damage, it found. 

Furthermore, 2.8 billion people cannot afford a healthy diet and 1 billion are undernourished, despite enough food being produced globally. The food system is also failing the 1 billion people living with obesity, the report said.

“What we put on our plates can save millions of lives, cut billions of tonnes of emissions, halt the loss of biodiversity, and create a fairer food system,” said Prof Johan Rockström, who co-chaired the EAT-Lancet Commission that produced the report. “The evidence is undeniable: transforming food systems is not only possible, it’s essential to securing a safe, just, and sustainable future for all.”

“This is not a deprivation diet,” said Prof Walter Willett of the Harvard TH Chan school of public health, and another commission co-chair. “This is something that could be delicious, aspirational and healthy. It also allows for cultural diversity and individual preferences, providing flexibility.”

The report, published in the Lancet, was produced by 70 leading experts from 35 countries and six continents. It builds on the 2019 report that introduced the PHD, but includes new evidence of the health benefits of the diet.

“We have been able to look at this diet in relation to health outcomes such as total mortality, diabetes, respiratory diseases, heart disease, stroke, etc and we found very strong inverse relationships” said Willett. The diet was also linked to reduced cancer and neurodegenerative diseases.

Overall, the researchers estimated global adoption of the PHD could prevent 15m early deaths a year in adults. The estimate did not include the impact of the diet reducing obesity, meaning it is probably an underestimate.

The PHD recommends plant-rich, flexible diets, including:

  • Fruits and vegetables – at least five portions a day
  • Whole grains – three to four portions a day
  • Nuts – one portion per day
  • Legumes (beans, peas, lentils) – one portion per day
  • Dairy – one serving of milk, yoghurt or cheese per day
  • Eggs – three to four a week
  • Chicken – two portions a week
  • Fish – two portions a week
  • Red meat – one portion a week

Dr Marco Springmann from UCL in the UK and an author of the report said the differences between the PHD and current diets vary: “What needs to be reduced differs a lot. In low income countries, it’s the starchy foods and grains, whereas in high income countries it is animal-sourced foods, sugar, saturated fats, and dairy. It’s insane how much dairy is consumed in Europe and North America.”

The data underlying the report is available online and can be used to tailor different planetary health diets for the tastes of people in specific countries and of different ages. The website also shows how much the diets reduce deaths, improve nutrition, and cut environmental impacts. 

“Hopefully this will lead to more science-based policymaking,” said Springmann.

The PHD is better than current average diets for many nutrients, including fatty acids, fibre, folate, magnesium and zinc. Adequate iron and vitamin B12 could be provided by green leafy vegetables, fermented soy foods and algae, the researchers said.

Moving diets towards the PHD could be achieved by helping consumers make better everyday choices, said Prof Line Gordon, director of the Stockholm Resilience Centre, for example by shifting taxes to make healthy foods cheaper, and putting warning labels on unhealthy foods. “But it is not just about getting prices lower, it’s also about bringing purchasing power up so that people can afford a healthier diet” she said.

“Our recommendations are grounded in scientific evidence and real-world experience,” Gordon said. “Changes are already under way, from school meal programmes to regenerative agriculture and food waste reduction initiatives.” England banned price promotions on unhealthy foods on Wednesday and will ban advertising such foods online.

The report estimates that food-related ill health and environmental damage costs society about $15tn a year. It said investments to transform the food system would cost $200bn to $500bn a year, but save $5tn.

Alongside a shift in diets, the report calls for other changes to the food system, including cutting the loss and waste of food, greener farming practices, and decent working conditions, as a third of food workers earn below living wages.

The launch of the PHD in 2019 led to attacks from meat industry interests. Rockström said: “The [new report] is a landmark achievement. It is a state-of-the-art scientific assessment that quantifies healthy diets for all human beings in the world and the environmental boundaries all food systems need to meet to stay safe. So we have a really rigorous foundation for our [results]. We are ready to meet that assault.”
