Climate finance encompasses two major goals: **Climate mitigation finance** (supporting low-carbon/zero-carbon projects: renewable energy, EVs, energy-efficient buildings) and **Climate adaptation finance** (supporting projects addressing climate change impacts: flood defense infrastructure, heat-tolerant crops, early warning systems). Currently approximately 80% of global climate finance flows to mitigation, with only approximately 20% toward adaptation — yet the most climate-vulnerable developing countries need adaptation funding most, making this imbalance a core issue in international climate finance negotiations.
## Green Bond Market
Green bonds are bonds specifically raising funds for projects with clear environmental benefits. Key characteristics: raised funds must be used for designated green projects (renewable energy, clean transport, green buildings, water management, etc.); issuers must disclose fund use and project environmental benefits per Green Bond Principles (GBP, issued by ICMA); third-party certification provides market quality assurance. Global green bond market: issuance exceeded $500 billion in 2023; China is one of the world’s major green bond issuers, with the People’s Bank of China publishing the Green Bond Endorsed Project Catalogue as the domestic green standard reference.
## ESG Investment and Climate Risk
Institutional investors (pension funds, insurance companies, sovereign wealth funds) increasingly incorporating ESG (Environmental, Social, Governance) considerations is bringing climate risk into mainstream investment decision-making. Core frameworks: **TCFD (Task Force on Climate-related Financial Disclosures)**: recommends companies disclose climate-related risks and opportunities in financial reports across four dimensions (governance, strategy, risk management, metrics and targets); **Transition Risk**: “stranded asset” risks for fossil fuel-related assets under tightening policy environments; **Physical Risk**: direct loss risks to corporate assets and supply chains from climate events like flooding and extreme heat.
## Developing Countries’ Climate Finance Difficulties
Developing countries (especially the most vulnerable small island states and low-income African nations) face structural barriers accessing climate finance: higher financing costs (higher borrowing costs due to lower sovereign ratings), complex application procedures (GCF’s application process is complex with high local institutional capacity requirements), insufficient funding scale (the “Loss and Damage” fund established at COP27 in 2022 still has a huge gap between developed countries’ committed funds and vulnerable nations’ needs).
