G20 Climate, Sustainability, Energy and Climate Finance Commitments

The report tracks G20 climate commitments from 2008 to 2024, noting a shift from general statements to specific goals like phasing out inefficient fossil fuel subsidies and implementing the Paris Agreement. It highlights the disruptive impact of US withdrawals from the Paris Agreement under the Trump administration and the challenges of institutional memory within the G20. For its 2025 presidency, South Africa focuses on 'solidarity, equality and sustainability', with specific priorities for Africa-focused energy access, climate-resilient agriculture, and scaling adaptation finance.

• G20 commitments to phase out inefficient fossil fuel subsidies began at the 2009 Pittsburgh Summit, with a joint report indicating that doing so by 2020 could reduce greenhouse gas emissions by 10% by 2050. However, progress has been varied; a 2012 compliance report showed member countries collectively scored 0.58 out of a possible +1 rating.
• The United States has repeatedly dissented from G20 consensus on climate action during the Trump administration, withdrawing from the Paris Agreement in 2017 and again on 20 January 2025.
• Climate finance commitments for developing countries have evolved from a goal of jointly mobilising $100 billion annually by 2020 to a 'floor' of $100 billion annually as of the 2023 New Delhi Summit. By 2024, developed nations settled on a target of $300 billion per year by 2035.
• The G20 suffers from a structural lack of institutional memory due to the absence of a permanent secretariat or centralised archive, leading to fragmented work and the tendency for annual agendas to revisit previously addressed topics.
• South Africa's 2025 G20 presidency, themed 'solidarity, equality and sustainability', prioritises the Global South through initiatives such as an Africa-focused roadmap for decentralised energy access, the establishment of climate financing for small farmers, and the development of a 10-year infrastructure plan for Africa.
