Reducing greenhouse gas emissions
Australia has made commitments to reduce its greenhouse gas emissions and has outlined various strategies to achieve this goal. The Australian government's Powering Australia plan aims to create jobs, reduce energy costs, and lower emissions by promoting renewable energy sources. This plan aims to capitalise on Australia's abundant natural resources to drive growth and establish the country as a renewable energy leader.
To encourage the adoption of renewable energy, the Australian Renewable Energy Agency (ARENA) provides funding for low-emissions technology and renewable energy projects. Additionally, the Renewable Energy Target (RET) scheme incentivises the generation of electricity from renewable sources, contributing to emissions reduction.
The Australian Carbon Credit Unit (ACCU) scheme is another initiative that provides incentives for organisations and individuals to adopt emission-reduction practices and technologies. The Climate Active program, under this scheme, encourages Australian businesses to become carbon neutral by offering the Climate Active Carbon Neutral Standard certification.
Australia has also pledged to stop financing fossil fuel projects abroad, although it continues to face challenges in reducing its domestic fossil fuel emissions. The government's approval of new coal mine projects and ongoing support for the oil and gas industry are misaligned with its emission reduction commitments and the Paris Agreement's goals.
To achieve net-zero emissions by 2050, Australia needs effective climate policies that decarbonise all sectors. This includes transitioning away from coal and gas exports and embracing clean energy technologies such as solar panels, wind turbines, and electric cars. While Australia has made some progress, stronger collective action and policy implementation are necessary to address the urgent threat of climate change.

Improving water governance
Australia is highly vulnerable to the effects of climate change, with the country already experiencing an increase of over 1.5 °C in average annual temperatures since the beginning of the 20th century. This has led to an increase in extreme weather events such as heatwaves, bushfires, droughts, and floods, as well as a longer fire season. Climate change is also causing water management problems, with changes in precipitation exacerbating existing water availability and quality challenges.
To address these issues, Australia has implemented various strategies and policies. The country has made commitments to reduce greenhouse gas emissions and transition to renewable energy sources. The Australian government has introduced schemes such as the Australian Carbon Credit Unit (ACCU) and the Renewable Energy Target (RET) to encourage emission reductions and promote renewable energy generation. Additionally, Australia has pledged to stop financing fossil fuel projects abroad and has developed plans to capitalize on its renewable energy resources and attract investment in clean industries.
However, there are still challenges and gaps in Australia's climate change response, particularly in water governance. While the Murray-Darling Basin has seen the establishment and reform of sophisticated water policy frameworks, these policies may not be adequate to address the escalating uncertainties surrounding adaptation pathways as the climate continues to warm.
To improve water governance in the context of climate change, Australia can consider the following actions:
- Enhance National, Multidisciplinary Collaboration: Water security in Australia can be improved by fostering collaboration between various disciplines and sectors at the national level. This includes engaging experts from different fields, such as hydrology, climate science, ecology, and social sciences, to develop comprehensive and adaptive water management strategies.
- Revision of Water Act and Basin Plan: The Australian government should prioritize the revision of the Water Act and Basin Plan by 2026 to address the increasing challenges posed by climate change. This revision should incorporate the latest scientific data and projections to ensure that water governance decisions are robust and adaptable to future climate scenarios.
- Strengthen Drought Resilience: As climate change intensifies droughts, long-term government-provided drought support is essential. This includes investing in drought-resistant infrastructure, promoting water conservation and recycling technologies, and developing drought contingency plans to ensure water security for communities and industries.
- Improve Water Quality: Climate change impacts water quality through increased temperatures, altered precipitation patterns, and ecological disruptions. Australia should implement measures to protect and restore water bodies, reduce pollution from agricultural and industrial sources, and enhance wastewater treatment processes to ensure safe and sustainable water resources for all.
- Water Pricing and Trading Mechanisms: Implementing water pricing reforms and market-based mechanisms, such as water trading or incentive schemes, can promote efficient water use, encourage conservation, and help manage water scarcity.
- Community Engagement and Education: Empowering communities through knowledge sharing and engagement is vital for effective water governance. Educating the public about water-related challenges and providing information on water conservation practices, sustainable land management, and the impact of climate change on water resources can foster a sense of collective responsibility and drive behavioral changes.
By implementing these strategies, Australia can improve water governance and enhance its resilience to the impacts of climate change on water resources.

Managing the impact of floods
Flooding is one of the costliest extreme weather events in Australia. Intense rainfall and subsequent floods can have devastating impacts over large areas, and their effects may persist for long periods. Climate change is expected to make storm and flood events more severe.
To manage the impact of floods, local councils in NSW, with assistance from the NSW Government, are responsible for implementing flood risk management strategies in their service areas. This includes considering how to develop flood-prone land appropriately, the viability of flood mitigation structures, and educating communities about flood risks. The NSW Government's Flood Data Portal provides information and support to local councils for managing flood risk before, during, and after floods.
The NSW Government is also adapting through the Floodplain Management Program and investing in research and the development of robust climate change projections. Local data on east coast lows and flash flooding is being gathered to help NSW plan for future events, as larger-scale climate models cannot provide detailed regional projections.
In Queensland, the Chief Scientist's Office has published "Understanding Floods: Questions and Answers" to explain fundamental flood concepts and risk management strategies. The report covers flood causes, impacts, forecasting, and flood risk management, with input from leading experts.
In the Gippsland Lakes, an artificial entrance to the ocean created in the 19th century has exacerbated the impacts of chronic salinisation. While engineering solutions can reduce saltwater and freshwater exchange, they may also pose challenges, such as surge barriers disrupting fish movements.

Reducing the risk of unprecedented wildfires
Australia has been experiencing an increase in average annual temperatures, with warming occurring at twice the rate over the past 50 years compared to the previous 50. This has resulted in the country becoming more prone to extreme heat, bushfires, droughts, floods, and longer fire seasons. While there have been some positive developments, such as the AUD 22.7 billion Future Made in Australia plan, which aims to capitalise on renewable energy and reduce reliance on coal and gas exports, more needs to be done to reduce the risk of unprecedented wildfires.
One key strategy is to focus on reducing greenhouse gas emissions, which are currently three times the global average per capita, with coal being responsible for 30% of these emissions. The Australian government has committed to reducing emissions by upgrading the electricity grid to support more renewable power and developing a Net Zero 2050 plan. Additionally, the Renewable Energy Target (RET) scheme encourages more electricity generation from renewable sources, and the Australian Renewable Energy Agency (ARENA) finances low-emissions technology and renewable energy projects.
Community-based efforts also play a crucial role in reducing the risk of wildfires. Groups like Landcare Australia help communities mobilise by providing funding and knowledge-sharing support for sustainable land management, natural habitat restoration, and enhancing biodiversity. Protecting local ecosystems is essential for advancing sustainability and productivity, benefiting all Australians.
Furthermore, addressing water management issues is vital. Changes in precipitation have exacerbated water availability and quality challenges, impacting both commercial and residential use. Implementing effective water governance decisions and collaborating nationally and multidisciplinary is essential to enhance water security in Australia.
While Australia has made some progress in reducing emissions and adapting to climate change, continued and accelerated efforts are necessary to mitigate the risk of unprecedented wildfires. This includes international cooperation, collective action, and holding governments and corporations accountable for their policies and practices.

Mitigating the health impacts of climate change
Climate change poses significant and growing threats to the well-being of Australians, with altered disease patterns, increased risks to food and water security, and more frequent and intense extreme weather events. Mitigating the health impacts of climate change in Australia requires a comprehensive approach involving government policies, community initiatives, and individual actions. Here are some key strategies to address these challenges:
Policy Responses
The Australian government has implemented various policies to reduce greenhouse gas emissions and build a more sustainable and resilient health system. The National Health and Climate Strategy, launched in December 2023, outlines priorities for the next five years, focusing on health system resilience, decarbonisation, international collaboration, and a "Health in All Policies" approach. This strategy aims to address the health and wellbeing impacts of climate change and reduce the health system's emissions, waste, and contribution to climate change. Additionally, the government has introduced the Australian Carbon Credit Unit (ACCU) scheme, the Renewable Energy Target (RET) scheme, and the National Greenhouse and Energy Reporting (NGER) scheme to reduce emissions and promote renewable energy sources.
Sustainable Transport and Agriculture
Encouraging sustainable transport options, such as active transport (walking and cycling), investing in public transport, and transitioning to electric vehicles can reduce transport-related emissions and improve air quality. This has significant health co-benefits. Additionally, implementing sustainable agricultural practices, such as improved livestock management, soil carbon sequestration, and preventing deforestation can reduce agricultural emissions and enhance food security.
Climate-Informed Early Warning Systems
Developing climate-informed early warning systems that incorporate socio-environmental factors and web-based search query data can effectively predict and control outbreaks of climate-sensitive infectious diseases. Integrating these systems with mHealth applications and artificial intelligence chatbots can facilitate targeted early warnings to stakeholders and communities.
Community and Individual Actions
Beyond government responses, community and individual actions are crucial for mitigating climate health effects. This includes reducing energy consumption at home, making sustainable consumer choices (such as reducing meat consumption and buying local and seasonal food), and supporting local initiatives to build climate-resilient communities.
Workforce Training and Education
Equipping healthcare professionals with the knowledge and skills to address the health impacts of climate change is essential. This includes understanding the risks posed by climate change, such as the increased incidence of heatstroke for outdoor workers and the challenges faced by rural communities in accessing healthcare during extreme weather events.
