Urgent action to cut greenhouse gas (GHG) emissions is needed now. Early next year, all countries will set new emissions targets for 2035 while revising their 2030 targets. Global GHGs must be cut by 25 and 50 percent below 2019 levels by 2030 to limit global warming to 2°C and 1.5°C respectively. But current targets would only cut emissions by 12 percent, meaning global ambition needs to be doubled to quadrupled. Further delay will lead to an ‘emissions cliff edge’, implying implausible cuts in GHGs and putting put 1.5°C beyond reach. This Note provides IMF staff’s annual assessment of global climate mitigation policy. It illustrates options for equitably aligning country targets with the Paris Agreement’s temperature goals. It also provides guidance on modelling needed to set emissions targets and quantify climate mitigation policy impacts.
Sierra Leone faces important development challenges. This includes dealing with the impacts of climate change such as rising temperatures, more frequent extreme hot days, and increasingly erratic rainfall patterns, with intensified single-day precipitation events. This is especially important given the country’s strong dependence on agriculture and hydropower. Climate change also requires improved Disaster Risk Management (DRM) and more forward-looking risk assessments. On the mitigation side, competing development needs have led to rapid urbanization and deforestation requiring a more integrated approach to land policy, planning, and forest protection. The country also needs substantial investments in its electricity, water, and waste sectors but private investment is lacking. The mission reviewed the current fiscal policies supporting climate action and provided recommendations to support the long-term climate resilience in Sierra Leone, while aligning with its overall development objectives.
Achieving the Paris Agreement’s temperature goals requires cutting global CO2 emissions 25 to 50 percent this decade, followed by a rapid transition to net zero emissions. The world is currently not yet on track so there is an urgent need to narrow gaps in climate mitigation ambition and policy. Current mitigation pledges for 2030 would achieve just one to two thirds of the emissions reductions needed for limiting warming to 1.5 to 2oC. And additional measures equivalent to a global carbon price exceeding $75 per ton by 2030 are needed. This IMF Staff Climate Note presents extensive quantitative analyses to inform dialogue on closing mitigation ambition and policy gaps. It shows purely illustrative pathways to achieve the needed global emissions reductions while respecting international equity. The Note also presents country-level analyses of the emissions, fiscal, economic, and distributional impacts of carbon pricing and the trade-offs with other instruments—comprehensive mitigation strategies will be key.
There is growing interest in international coordination over climate mitigation policy. Climate clubs or international carbon price floors could complement the Paris Agreement by helping to deliver the near-term cuts in global greenhouse gas emissions needed to contain global warming to 1.5 to 2oC. To ensure inclusivity, these arrangements need to account for varying mitigation policies across countries, including carbon pricing, fuel taxes, subsidy reform, and non-pricing approaches like regulations. A transparent methodology is needed to compare and monitor mitigation effort by countries implementing diverse policy packages. This paper presents and illustrates a methodology for converting climate mitigation policies and targets into their carbon price equivalents and applies it to the Group of Twenty (G20) countries.
This paper discusses potential elements of a comprehensive strategy for making headway on Türkiye’s net zero emissions pedge for 2053. These elements include: (i) aligning 2030 emissions commitments with long term neutrality; (ii) implementing a carbon price rising to an ilustrative $75 per tonne by 2030; (iii) enhancing acceptability through using carbon pricing revenues efficiently and equitably and including competitveness measures; (iv) introducing various feebate schemes (the fiscal analogue of regulations) to reinforce mitigation incentives in the power, industry, transport, building, forestry, and agricultural sectors. According to modelling results a phased revenue-neutral $75 carbon price reduces CO2 emisisons 21 percent below baseline levels in 2030, raises revenues of 1.7 percent of GDP, avoids 11,000 air pollution deaths over the decade, while imposing an average burden on households of 3 percent of their consumption (before revenue-recycling). With revenues used for targeted transfers and labor tax reductions the overall policy is pro-poor and pro-equity (average household is better off by 0.4 percent).
To stabilize the climate, global greenhouse gas emissions must be cut by 25 to 50 percent by 2030 compared to 2019. Such an unprecedented rate of decarbonization necessitates climate mitigation policies across countries, notably carbon pricing, fossil fuel subsidy reform, renewable subsidies, feebates, emission rate regulations, and public investments. To design and implement effective, efficient, and equitable policies, governments need tools to assess economic, environmental, fiscal, and social impacts. To support this effort, the IMF and World Bank are making their joint Climate Policy Assessment Tool (CPAT) available to governments. CPAT is a transparent, flexible, and user-friendly model covering over 200 countries. It allows for the rapid quantification of impacts of climate mitigation policies, including on energy demand, prices, emissions, revenues, welfare, GDP, households and industries, local air pollution and health, and many other metrics. This paper describes the CPAT model, its data sources, key assumptions, and caveats.
Internationally coordinated climate mitigation policies can effectively put the world on a path toward achieving the agreed Paris temperature goals. Such coordination could be initiated by large players, such as China, the US, India, the African Union, and the European Union. We find that the implications for fiscal revenues over time will be shaped by a combination of rising carbon prices, the gradual erosion of existing fuel tax bases, and possible revenue sharing arrangements. Public spending rises during the transition to build green public infrastructure, promote innovation, and support clean technology deployment. Countries will also need financing for compensating vulnerable household...
Addressing climate change will entail major challenges for economic growth, employment, inflation, and public finances. Mitigating the impact of global warming will yield benefits and costs that are yet to be quantified and defined for the global economy and for nations, workers, households, and companies. The Green Frontier: Assessing the Economic Implications of Climate Action offers research originally presented at a major conference at the Peterson Institute for International Economics in June 2023 in Washington, DC, organized to shed light on this still unexplored field of study and recommend policies for the future.
Chile: Selected Issues
Urgent and aggressive action to cut greenhouse gas emissions this decade is needed. As countries take stock of the Paris Agreement, this Note provides IMF staff’s annual assessment of global climate mitigation policy. Global ambition needs to be more than quadrupled: emissions cuts of 50 percent below 2019 levels by 2030 are needed for 1.5 degrees Celsius, but current targets would only achieve 11 percent. We provide options for ratcheting-up ambition equitably. Implementation could be accelerated via agreements on minimum carbon prices. Drastic increases in mitigation investment are needed, requiring policies to shift private sector incentives. Climate finance should be scaled-up, with a new goal aligned with needs in developing countries. The development and diffusion of low-carbon technologies should be accelerated collaboratively. Overall, the Paris Agreement is making progress, but a response to the Global Stocktake that prioritizes decisive action this decade is critical.
