Australia raises climate ambition with new targets and financial boost for decarbonisation

On 18 September 2025, Australia took a significant step forward in its climate policy by announcing a new national emissions reduction target of 62% to 70% below 2005 levels by 2035. This ambitious commitment, articulated by Prime Minister Anthony Albanese and supported by senior ministers and the Climate Change Authority (CCA), marks a substantial escalation from the previous 43% reduction goal set for 2030. The announcement was grounded in scientific evidence and practical planning and coincided with the release of Australia’s first national climate risk assessment, which quantified the severe economic risks posed by climate change to the nation’s economy.

To support the achievement of this robust target, the Australian government has unveiled a comprehensive AU$7 billion climate finance package. Central to this is a AU$5 billion Net Zero Fund within the National Reconstruction Fund designed to assist industries in decarbonisation, alongside an additional AU$2 billion boost to the Clean Energy Finance Corporation (CEFC) to accelerate renewable energy initiatives. The CCA’s recommendation for the 62% to 70% reduction range emerged after extensive consultation and analysis, describing the target as ambitious yet achievable, though it necessitates halving emissions across multiple sectors within the next decade.

The government’s commitment also aligns with efforts to modernise Australia’s energy landscape beyond emissions reductions. A notable development within this policy framework is the AU$1.1 billion investment announced on 17 September dedicated to a 10-year Cleaner Fuels Program. This initiative aims to stimulate private sector investment in domestic renewable diesel and sustainable aviation fuel (SAF) production. By fostering a homegrown SAF industry, Australia intends to enhance energy security and economic resilience while capitalising on abundant feedstocks such as canola, sorghum, sugar, and waste. The CEFC projects that this burgeoning industry could reduce carbon emissions by approximately 230 million tonnes CO₂-e cumulatively and contribute an estimated AU$36 billion to the Australian economy by 2050, creating thousands of jobs in renewable energy and advanced manufacturing sectors.

Nevertheless, the path to these emissions targets is not without challenges. The CCA’s 2035 Targets Advice report highlights the rapidly expanding energy demands of artificial intelligence (AI) technologies and data centres as significant risks to Australia’s emissions reduction efforts. Projections suggest that by 2050, data centres supporting AI systems could consume up to 12% of the national electricity grid, with an annual growth rate of 25%. This growing demand calls for strategic energy management solutions, including co-location of data centres with battery storage and increased investment in energy-efficient technologies to mitigate emissions risks.

Alongside these technical and investment challenges, regulatory frameworks concerning sustainable investment have been under scrutiny in Australia. The Treasury’s recent consultation on the introduction of a Sustainable Investment Product Label regime attracted mixed responses from industry bodies. Some responsible investment organisations warned that a rigid, one-size-fits-all labelling system could destabilise Australia’s superannuation system by excluding certain high-quality products and creating onerous compliance burdens. Conversely, a major accounting body advocated for stricter naming, marketing, and disclosure rules to combat greenwashing, proposing a hybrid regulatory framework combining principles-based standards with mandatory disclosures and minimum asset thresholds. As the consultation phase has concluded, stakeholders await decisions on how the government will balance competing demands to shape a credible but flexible labelling regime.

On the global stage, Australia’s recalibrated emissions target and financing commitments correspond with broader efforts to harmonise climate-related standards and grow sustainable finance markets. In Europe, Denmark launched the first sovereign green bond fully compliant with the newly developed European Green Bond Standard (EuGBS) in September 2025. This framework, produced in alignment with the EU Taxonomy and Green Bond Principles, sets a new benchmark for transparency and environmental integrity in sustainable finance. Denmark’s issuance of a DKK 7 billion 10-year green bond funds taxonomy-aligned projects supporting the green transition, including energy transformation, sustainable transport, and nature restoration. This landmark issuance is viewed as a potential template for sovereign sustainable finance markets globally, offering investors greater certainty over environmental credentials.

Furthermore, an important partnership between the International Organisation for Standardisation (ISO) and the Greenhouse Gas Protocol was announced in early September 2025. The collaboration seeks to unify and co-develop global standards for greenhouse gas (GHG) emissions accounting and reporting, merging the ISO 1406X family of standards with the GHG Protocol’s corporate and scope-based standards. This integration aims to reduce fragmentation in climate reporting, improving the technical rigour, policy relevance, and usability of GHG frameworks. Such harmonisation is expected to enhance transparency for investors and facilitate better capital allocation decisions amid the global energy transition.

Despite these national and international efforts, broader analyses from the United Nations Climate Change Secretariat indicate that while global greenhouse gas emissions may start to decline within the next decade if current pledges are fully implemented, the anticipated 10% reduction by 2035 significantly trails the 60% cut necessary to limit warming to 1.5°C. This shortfall underscores the urgency of stronger climate action as countries gather for forthcoming COP30 negotiations. Notably, major emitters like the United States are currently scaling back climate policies, and key players such as China and the European Union have yet to finalise or submit enhanced targets, adding uncertainty to global efforts.

For industrial decarbonisation stakeholders in Australia and beyond, the evolving policy landscape underscores the complexity of balancing ambitious emissions reductions with sectoral realities and technological advances. Australia’s increased 2035 target and financial commitments mark a pivotal advancement in the country’s climate strategy, one that will demand coordinated action across government, industry, and finance to navigate emerging energy challenges, regulatory developments, and opportunities arising from burgeoning clean fuel industries and international sustainable finance frameworks.
