Australia’s 2023 International Development Policy (IDP) sets clear commitments on strengthening the integration of climate change into its development programme. The 2023 IDP and Australia’s Climate Change Action Strategy (2020-2025) set a target, starting from financial year 2024/25, to have a climate change objective for at least half of all new bilateral and regional investments valued at more than AUD 3 million, aiming to reach 80% by 2028/29. In 2022-2023, Australia committed 45.0% of its total bilateral allocable ODA (USD 1.1 billion) in support of the environment and the Rio Conventions, up from 35.8% in 2020-2021. A higher share (45.0%) of total bilateral allocable ODA (USD 1.1 billion) also focused on climate change overall compared to 34.4% in 2020-2021 (OECD, 2025[7]). This trajectory indicates that Australia is on track to meet its targets.
In line with the Declaration’s emphasis on the need to scale up climate action, Australia’s 2023 IDP commits to increase the total number of climate-related investments. However, Australia has largely relied on its existing ODA budget to reach its climate targets. At COP29, Australia strengthened its climate finance commitment with an expectation to deliver AUD 3 billion (USD 2 million) in global climate finance over 2020-2025. However, this will largely be achieved through existing ODA commitments, rather than new and additional climate finance (OECD, 2025[8]).
Australia integrates climate objectives into its development programmes. At the country level, climate change risks and opportunities are considered through Development Partnership Plans, which are aligned with partner governments’ Nationally Determined Contributions and National Adaptation Plans, and through programme design at investment level. Guidance to integrate climate into development programmes was issued in May 2024 for DFAT staff and key implementing partners. A new Climate Resilient Communities Facility (AUD 208.5 million, 2024/25 to 2028/29) aims to incentivise DFAT country and regional programmes to integrate climate change across the development programme and increase climate investments over time.
Australia’s development co-operation has a strong focus on supporting climate adaptation and resilience, in line with the priorities of Small Island Developing States (SIDS), as called for in the Declaration. Reflecting this focus, in financial year 2022/23, Australia targeted a greater proportion of its climate ODA commitments to adaptation (42.5%) than to mitigation (22.9%) (OECD, 2025[7]). Australia’s support for climate adaptation in Pacific Island countries has a strong focus on disaster resilience and preparedness. This includes supporting community-based disaster risk reduction initiatives, work with Indo-Pacific governments, regional organisations, and partners to scale-up anticipatory approaches and improve the planning and availability of disaster risk financing, greater regional response capabilities, and humanitarian supply stores positioned closer to disaster-prone areas. Australia is also investing in climate and disaster resilient infrastructure under the Pacific Climate Infrastructure Financing Project (PCIFP), implemented through AIFFP. Australia is also a member of multilateral initiatives such as the Coalition for Disaster Resilient Infrastructure, the Blue Dot Network, and the G20 Infrastructure Working Group.
Australia uses blended finance mechanisms to mobilise additional private sector investment to address climate challenges, for example to deliver off-grid renewable energy projects in remote and rural communities under PCIFP. In 2023, Australia launched the AUD 250 million Australian Development Investments (ADI), which focuses on climate resilience and gender equality. ADI is an expanded version of its predecessor, the Emerging Markets Impact Investment Fund, which was established in 2020. This aligns with the Declaration’s call for the use of ODA to leverage additional public, private and blended finance. ADI also supports the integration of gender lens investing through technical assistance grants to investee funds and portfolio companies. This supports its implementation of the Declaration’s emphasis on gender responsive, equitable climate action. DFAT reports that its blended finance mechanisms are demonstrating strong climate outcomes. In 2024, ADI portfolio companies reportedly abated 110 608 tons of CO₂eq, comparable to removing an estimated 23 405 gasoline-powered cars from the road for a year. In addition, DFAT reports that ADI’s investments added 145.60 MW of new solar capacity, enough to power around 145 000 households annually across Southeast Asia.
Australia advocates on behalf of Pacific Island countries in line with the Declaration’s recognition of the challenges faced by SIDS in accessing international climate and environment funds. Australia advocates for increased recognition of the distinct challenges faced by Pacific SIDS to climate threats and backs their calls for increased access to concessional finance for climate resilience in multilateral contexts, including in its support to global climate funds such as the Green Climate Fund. Australia has also aimed to address the climate finance gap faced by Pacific SIDS through supporting regional funds, including a AUD 100 million foundational contribution to the Pacific Resilience Facility.
Australia’s 2023 IDP commits to expanding support for environmental protection and biodiversity conservation, but only 4% of its ODA is focused on environmental issues as a principal objective, compared with the DAC average of 9.6% in 2022-2023. In the same period, 4% of Australia’s screened bilateral allocable ODA (USD 106.1 million) focused on biodiversity overall, down from 6.5% in 2020-2021. The small proportion of, and decline in, Australia’s biodiversity ODA contrasts with its aims to promote the sustainable management and use of ocean and coastal resources in the Pacific, in line with the aims of the Declaration. Australia will support Palau’s Chairing of AOSIS (2025-2026) by helping resource AOSIS’ negotiating capacity to strengthen the ability of SIDS to shape outcomes in the Intergovernmental Negotiating Committee on Plastic Pollution, the Agreement on Marine Biodiversity of Areas beyond National Jurisdiction (BBNJ Agreement), and the Third United Nations Ocean Conference. Further support for biodiversity and the environment in its climate finance and development programming would strengthen Australia’s implementation of the Declaration and align with its support for regional priorities and vulnerabilities.
