Bridging the Gap: How to Finance the Net-Zero Transition

The report identifies a massive shortfall in climate finance, with annual requirements projected to reach $9 trillion by 2030. It highlights a stark disparity between developed nations and emerging markets, noting that the latter face higher capital costs and institutional weaknesses. The authors analyze various mobilization tools, including concessional finance, sustainable debt, and hybrid mechanisms like blended finance. Case studies of the EU's Green Deal and the US Inflation Reduction Act illustrate different strategic approaches, while the report concludes with design principles—coherence, fairness, and appeal—to make market instruments more effective at altering consumer behaviour.

• Global annual climate finance requirements are projected to reach $9 trillion by 2030 and exceed $10 trillion annually between 2031 and 2050, yet only $1.2 trillion was invested in 2021/2022.
• There is a significant disparity in climate finance distribution; developed countries received 44% of total tracked capital in 2021-22, while emerging markets and developing economies (excluding China) received only 14%.
• Developing countries face severe barriers to private investment, including capital costs that are often five to ten times higher than in developed nations, alongside political uncertainty and a lack of bankable project pipelines.
• The energy sector requires the most substantial investment, with cumulative capital needs exceeding $125 trillion by 2050 and annual needs of $4.5 to $5.7 trillion by 2030.
• Fossil fuel subsidies remain a major obstacle to the transition, with $1.3 trillion in explicit and $5.7 trillion in implicit subsidies recorded in 2022.
• The sustainable debt market reached a cumulative size of $4.4 trillion in 2023, though issuance for sustainability bonds and development bank projects saw substantial declines that year.
• The EU's Emissions Trading System (EU-ETS) helped reduce emissions from European power and industry plants by approximately 47% between 2005 and 2023.
• The EU's Carbon Border Adjustment Mechanism (CBAM) aims to prevent carbon leakage by pricing imports from countries with laxer climate policies, though it may increase the cost of delivered steel from India and China by 56% and 49% respectively by 2034.
• The US Inflation Reduction Act (IRA) is projected to reduce US greenhouse gas emissions by 33% to 40% below 2005 levels by 2030 through a mix of tax credits, grants, and regulatory policies.
• To effectively alter consumer behaviour, the report proposes three design principles for market instruments: coherence (ease of understanding), fairness (accounting for socio-demographic variations), and appeal (linking revenues to R&D and subsidies).
