Colombia is deeply committed to climate change policies, as evidenced by Law N° 1931 (2018), which outlines actions to adapt to climate change and reduce greenhouse gas emissions, aiming to decrease the vulnerability of the population and ecosystems while promoting a sustainable, low-carbon economy. The National Statistical office of the country, Departamento Administrativo Nacional de Estadística (DANE), is dedicated to developing integrated environmental and economic data, and regularly compiles and disseminates selected accounts from the System of Environmental-Economic Accounting (SEEA). However, to effectively implement climate change mitigation and adaptation strategies, Colombia requires substantial amounts of granular, relevant, and reliable data for evidence-based planning. In this context, a mission took place from July 17-21, 2023, funded by the Swiss State Secretariat for Economic Affairs (SECO) and hosted by DANE. During this mission, discussions with authorities focused on key priorities, identifying feasible developments such as enhancements to existing SEEA energy and emissions flow accounts, mineral and energy asset accounts, and the establishment of domestic carbon footprints.

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 policy at the subnational level is sometimes framed as being counterproductive, because climate change is considered a collective action problem that can be best addressed in a coalition that should be as large as possible. Using comprehensive data from US states on climate policy and policy outcomes, we show that state-level policy is effective in accelerating the adoption of solar energy. Crucially, however, state policies also have positive spillovers to other states, by making it more likely that neighboring states adopt climate policy as well. By proportionally attributing the spillover effects, we find that many US states achieve more climate benefits through the spillovers to other states than within their own jurisdiction. In a further step, we distinguish between climate policies in the energy sector and policies addressed either at other sectors or greenhouse gas emission (GHG) reductions generally. We find that climate policies in the energy sector are distinct from other climate policies in two ways: They have a significant effect on solar capacity growth and they diffuse more broadly.

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.
