Multifactor productivity is a comprehensive measure of productivity where the underlying production function accounts for multiple factor inputs, traditionally labour and produced capital. While single-factor productivity is intuitively simple, such measure offers a biased picture of the economy because it attributes all variation in output growth to a single factor input (e.g. consumption of fossil fuels or material resources) while the role of other factors is ignored. Multifactor productivity aims at addressing this shortcoming, and as such it is a valuable component of the OECD set of Green Growth headline indicators. This paper presents further progress in measuring the EAMFP and related growth accounting indicators in 52 countries for 1996-2018. An important novelty is the inclusion of renewable natural resources such as land, timber and fisheries, and ecosystem services such as coastal and watershed protection. Exploratory results on accounting for renewable energy resources are also included.

The Mitigation Work Programme (MWP) was established at COP26 to urgently enhance mitigation ambition and implementation in this critical decade. This paper explores how the MWP could build on and amplify relevant existing efforts, within and outside the UNFCCC, to trigger the rapid scale up of mitigation efforts required to keep the temperature goal of the Paris Agreement within reach. As a multilateral platform backed by the legitimacy and convening power of the UNFCCC, the MWP could help to raise awareness of available tools and solutions, build momentum behind relevant ongoing mitigation-related initiatives without being prescriptive, and deliver more effective, targeted mitigation efforts across all fronts in the near-term. This paper also outlines potential options for the annual decision on the MWP which provides an important opportunity to maintain attention on the need to urgently scale up mitigation efforts and encourages learning-by-doing. The annual MWP decision could be structured around different mutually supportive elements including lessons learned from the MWP’s first year, follow-up from MWP activities and related mitigation commitments at previous COPs, synergies with other UNFCCC processes, and how to complement the global stocktake.

L’Observateur de l’action climatique est une des principales publications du Programme international pour l’action sur le climat (IPAC). Cette synthèse couvre les mesures relatives à la lutte contre les changements climatiques et les progrès accomplis en vue de la neutralité carbone dans 51 pays de l’OCDE et partenaires de l’OCDE. Cette année, le rapport contient un résumé des informations relatives aux émissions de gaz à effet de serre, une évaluation des aléas climatiques et les dernières tendances en matière de mesures relatives à la lutte contre les changements climatiques. Les décideurs politiques et les acteurs de terrain sont les destinataires de cette synthèse dont les résultats montrent que, à moins d’être plus ambitieux et d’accroître significativement l’envergure des actions en faveur du climat à l’échelle nationale, les pays ne relèveront pas le défi de la neutralité carbone.

This report analyses current trends of adaptation finance provided and mobilised by developed countries for developing countries. It explores potential action areas for international providers to scale up funding for climate change adaptation, including by unlocking the potential of the private sector. The analysis is anchored in the context of the USD 100 billion climate finance goal, initially set for 2020 and extended to 2025, while also providing insights to the broader and longer-term objective of supporting developing countries’ ability to adapt to the adverse impacts of climate change.

Ce rapport présente les tendances agrégées du financement climatique annuel fourni et mobilisé par les pays développés pour les pays en développement sur la période 2013-2021. Les tendances sont présentées par thème climatique, secteur, par instrument financier et par groupe de pays bénéficiaires pour la période 2016-2021. Le rapport fournit également des recommandations clés pour les bailleurs de fonds internationaux afin d'augmenter le financement de l'adaptation et de mobiliser plus efficacement le financement privé pour l'action climatique, qui sont à la fois des priorités politiques importantes et des éléments représentants un défi à l’heure actuelle. Les recommandations de ce rapport se basent sur deux publications de l'OCDE sur l'augmentation des financements privés pour le climat et l'adaptation.

This report explores evidence-based action areas to increase and accelerate the mobilisation of private finance for climate action in developing countries, and the role of international public finance providers in doing so. It draws on best-available data to provide disaggregated analysis of the sectoral, geographic and other features of private finance mobilised by public climate finance and presents key economy-wide, sector-specific, and institutional challenges to private finance mobilisation. The analysis is anchored in the context of the USD 100 billion climate finance goal, initially set for 2020 and extended to 2025, while also providing insights related to mobilising private finance for climate action in developing countries more broadly.

Extended Producer Responsibility (EPR) is a policy approach that makes producers responsible for their products at the post-consumer stage of the lifecycle. It has been widely adopted by governments and companies across the OECD membership and beyond and is currently most commonly used for electronics, packaging, vehicles, and tyres. The success of EPR in increasing material recovery rates has triggered a debate about expanding the use of EPR to additional product groups. Additionally, there is a debate about expanding producer responsibilities to additional impact categories, which go beyond the traditional use of EPR to cover end-of-life costs that occur at the domestic level. This paper presents a discussion of relatively novel applications of EPR to additional product groups (plastic products beyond packaging, textiles, construction materials, and food waste) and to environmental impacts (design considerations, pollution and littering) that occur throughout the product lifecycle. Based on select case studies, this report evaluates the successes and challenges that early adopters of applying the EPR approach to new product groups or additional environmental impact categories have experienced. It reviews the arguments for further application of EPR, possible limitations and provides guidance on when and how to best apply an EPR.

This paper provides empirical evidence on the short and long-term sectoral effect of environmental policy stringency on CO2 emissions, exploiting longitudinal data covering 30 OECD countries and more than 50 sectors. The analysis relies on the OECD Environmental Policy Stringency (EPS) index, a composite index tracking climate change and air pollution mitigation policies. Estimates obtained from panel regressions suggest that more stringent environmental policies are associated with lower emissions, that the effect builds over time and differs across sectors depending on their fossil fuel intensity. A one unit increase in the EPS index (about one standard deviation), is associated with 4% lower CO2 emissions in the sector with median fossil fuel intensity after two years and by 12% after 10 years. For sectors in the top decile of the fossil fuel intensity distribution, the estimates point to a decline in emissions by 11% after two years and 19% after ten years. Environmental policies targeted at energy, manufacturing and transport sectors have the largest potential impact on emissions. Illustrative policy scenarios based on these results indicate that achieving emission reductions consistent with net-zero targets will require raising the stringency of environmental policies more drastically and rapidly than in the past.
