Abstract

There are major gaps in the measurement of the adoption and stringency of countries’ climate actions and policies, notably in a manner coherent across countries, time, sectors, and instrument types. The Climate Actions and Policies Measurement Framework (CAPMF) aims to fill this gap. It is the most extensive structured and internationally harmonised climate mitigation policy database available to date. Currently, it comprises 130 policy variables, grouped into 56 policy instruments and other climate actions, covering 50 countries and the EU-27 as a block for the period 1990–2022. Results indicate that countries strengthened their climate action between 1990 and 2022 in terms of policy adoption and policy stringency, although at different paces. Policy adoption, policy stringency and policy mixes changed over time and differ substantially across countries and country groups. Importantly, regression analysis suggests a significant relationship between stronger climate action and greater emission reductions. Mitigation policies helped reduce emissions by about 12% in the last 5 years; most of this effect is attributable to a reduction in the energy intensity of the economy, and only residually to other factors such as a reduction of GHG intensity.

气候行动与政策衡量框架:监测和评估各国减缓行动的数据库
摘要 在衡量各国采取的气候行动和政策及其严格程度方面存在重大差距,特别是在国家、时间、部门和工具类型之间的一致性方面。气候行动与政策衡量框架(CAPMF)旨在填补这一空白。它是迄今为止最广泛的结构化和国际统一的气候减缓政策数据库。目前,该数据库包括 130 个政策变量,分为 56 个政策工具和其他气候行动,涵盖 1990-2022 年期间的 50 个国家和欧盟 27 国。结果表明,在 1990 年至 2022 年期间,各国在政策采用和政策严格性方面加强了气候行动,尽管速度不同。政策采用、政策严格程度和政策组合随着时间的推移而变化,并且在不同国家和国家组之间存在很大差异。重要的是,回归分析表明,更有力的气候行动与更大的减排量之间存在显著关系。在过去 5 年中,减排政策帮助减少了约 12%的排放量;这一效果大部分归因于经济能源强度的降低,仅有部分归因于其他因素,如温室气体强度的降低。
