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.

Climate change presents an unprecedented long-term challenge to the French and global economy. While France has made significant progress towards reducing greenhouse gas emissions, important additional policy efforts will be needed to meet key mitigation targets. Decarbonization costs and risks can be significant, highlighting the need to identify efficient and equitable fiscal and regulatory policy options to meet emission goals. To accelerate the green transition and mitigate its costs, France has increasingly relied on green spending measures, which could be complemented by higher carbon pricing and other revenue-neutral schemes. Recycling of revenues via cash transfers could offset the price impact on lower-income households. Over the medium term, new measures for road transportation, such as distance-based charges, could also be considered. Ensuring a timely and orderly climate transition will be critical to mitigate the credit risk impact on banks. French banks should also continue to mitigate climate transition risks by integrating them into their governance, strategy, and risk management processes.

This paper assesses the economic effects of climate policies on different regions and countries with a focus on external adjustment. The paper finds that various climate policies could have substantially different impacts on external balances over the next decade. A credible and globally coordinated carbon tax would decrease current account balances in greener advanced economies and increase current accounts in more fossil-fuel-dependent regions, reflecting a disproportionate decline in investment for the latter group. Green supply-side policies—green subsidy and infrastructure investment—would increase investment and saving but would have a more muted external sector impact because of the constrained pace of expansion for renewables or the symmetry of the infrastructure boost. Country characteristics, such as initial carbon intensity and net fossil fuel exports, ultimately determine the current account responses. For the global economy, a coordinated climate change mitigation policy package would shift capital towards advanced economies. Following an initial rise, the global interest rates would fall over time with increases in the carbon tax. These external sector effects, however, depend crucially on the degree of international policy coordination and credibility.
Large reductions in global emissions are needed for the world to be on track to meet global temperature goals. Asia-Pacific countries have a critical role in emissions reduction given their large and rising share in global emissions. This paper discusses the main opportunities and behavioral responses for reducing emissions, and commonly used mitigation instruments. It then considers key design issues for carbon pricing, with a focus on emissions trading schemes (ETS), describes measures to overcome the obstacles to carbon pricing, and discusses experiences with carbon pricing relevant for Asia-Pacific economies. Lastly, the paper covers complementary policy reforms, including reinforcing mitigation instruments, public investment, fuel tax reform, green industrial policies, and supporting reforms to the energy sector. Carbon pricing, including ETSs can be the centerpiece of climate mitigation strategies for most countries, particularly if ETSs are designed to mimic some of the administrative and economic attractions of carbon taxes and implemented appropriately.

This technical assistance conducts a climate policy diagnostic for Jordan, covering climate adaptation and mitigation policy, as well as enabling institutions. Jordan faces acute challenges of climate-food-water nexus—innovative climate policy approaches are key, given limited fiscal space. While Jordan needs to strengthen the investment climate for climate investment through streamlining existing policies and alleviating critical barriers, making social policy more shock-responsive and strengthening risk management can go a long way in building resilience. As climate-related risks globally intensify, the government is encouraged to move toward a risk-informed policy and financing strategy.

Mauritania requested capacity development from the Fiscal Affairs Department on carbon taxation, fossil fuel pricing and fiscal aspects of hydrogen development. This is a high-level summary of the technical assistant and the recommendations provided to the authorities. The report assesses options to gradually introduce a carbon tax to bring the country in line with its Nationally Determined Contribution for 2030 and net-zero pledge for 2050, including targeted support for vulnerable households. It then reviews approach to price fossil fuel products and proposes a revised methodology better aligned with international petroleum markets, along with a fiscally neutral smoothing mechanism to mitigate the impact of abrupt price changes on Mauritanian consumers. Finally, the report evaluates fiscal aspects related to the development of the low and zero-emissions hydrogen to ensure the country continues to position itself as an attractive investment destination without foregoing future revenue streams.
