      "heading": "Green investment",
      "content": "- Radically transforming the energy system requires scaled-up investments for:\n  - shifting from fossil fuels to renewables;\n  - smart electricity networks;\n  - energy efficiency measures;\n  - electrification in sectors like transport, buildings, and industry;\n  - R&D for low-carbon technologies.\n- Investment dynamics:\n  - In many sectors, reducing emissions involves higher upfront investment for new infrastructure but lower recurrent costs due to reduced fuel consumption.\n  - Investment is described as hump-shaped: an increase in the next 20 years and a decrease to recent historical levels after that.\n- Aggregate investment needs:\n  - An estimated additional $6 to 10 trillion in global investments, both public and private, are needed in the next decade to mitigate climate change.\n  - This amounts to a cumulative 6-10 percent of annual global GDP.\n  - According to International Energy Agency data, about 30 percent of additional investment, on average globally, is expected to come from public sources — that is a cumulative 2-3 percent of annual GDP for the decade 2021 to 2030.\n  - The remaining 70 percent would be private.\n- Policy levers to mobilize investment:\n  - Use COVID-19 fiscal recovery packages to invest in a low-carbon transition.\n  - Move toward comprehensive green budgeting to examine “brown” and “green” incentives and align budgets with nationally determined contributions (NDCs) and the Paris Agreement goals.\n  - Improve investment frameworks, create pipelines of bankable projects, and use international public financing to reduce perceived risks and bring down the high cost of capital, especially in emerging and developing economies.\n  - Financial sector policies: require disclosures of climate-related risks and establish a common taxonomy of green and brown assets to channel financial flows into sustainable investments."

      "content": "- A just transition has domestic and international dimensions.\n- Domestic measures:\n  - Help households struggling to afford basic necessities pay for higher energy costs.\n  - Support coal miners and other workers and communities dependent on high-carbon sectors for their livelihoods.\n- International measures:\n  - Financial support is necessary for developing economies, which are expected to incur greater costs in the transition yet have limited means to pay.\n  - Many developing economies are prepared to ramp up their NDCs if they receive climate finance.\n  - Because many of the world’s lowest-cost mitigation opportunities exist in emerging and developing economies, climate finance advances global interest by enabling those opportunities."
