Fiscal spending policies adopted in the wake of the COVID-19 pandemic have been presented as a unique opportunity to “build back better” and re-ignite the economy while accelerating the transition to a low-carbon economy. This paper analyses 1 166 funding measures announced by 51 countries and the European Union in 2020-21 to support development and diffusion of low-carbon technologies. These measures – amounting to USD 1.29 trillion – can make an important contribution to filling the climate investment gap, particularly in emerging technologies such as carbon capture, usage and storage and green hydrogen. A modelling analysis suggests that they could have large impacts on greenhouse gas emissions and bring about significant co-benefits in terms of clean sectors’ output growth and reductions in fossil fuel imports.

Alors que les plastiques sont des matériaux extrêmement utiles, la production de plastiques et la production de déchets continuent d'augmenter avec une aggravation des impacts environnementaux, malgré les réponses des politiques internationales, nationales et locales, ainsi que les engagements du secteur de l'industrie. Le besoin urgent de rendre le cycle de vie des plastiques plus circulaire appelle à une expansion des politiques nationales et à une meilleure coopération internationale pour atténuer les impacts environnementaux du plastique. Le premier de deux rapports, ces Perspectives visent à informer et à soutenir les efforts politiques pour lutter contre les rejets de plastique. Le rapport quantifie les niveaux actuels de production, d’utilisation, de génération de déchets et les principaux impacts environnementaux tout au long du cycle de vie des plastiques et identifie les opportunités de réduction des externalités négatives. Il étudie également comment l'utilisation de plastique et la génération de déchets de plastiques ont été affectés par la pandémie de COVID-19 dans les différentes secteurs et régions. Les Perspectives identifient quatre leviers essentiels pour infléchir la courbe des matières plastiques : un soutien plus important aux marchés des plastiques recyclés, stimuler l’innovation technologique, une action publique nationale plus ambitieuse, et une meilleure coopération internationale.

L’Examen de l’OCDE des pêcheries 2022 rassemble des données sur la gestion des pêches et les mesures de soutien connexes, qui y sont analysées afin d’éclairer la prise de décisions en faveur d’une pêche durable et résiliente, qui soit source d’emplois, d’alimentation et de revenus pour les générations à venir. Y sont évalués l’état de santé et la productivité des stocks halieutiques, et étudiés les moyens de mieux les gérer. L’Examen repose sur l’analyse d’une version actualisée de la base de données de l’OCDE « Estimation du soutien à la pêche et à l’aquaculture (ESPA) », qui constitue l’ensemble de données par pays le plus complet et le plus détaillé dont on dispose sur le soutien public accordé au secteur dans les pays de l’OCDE et d’autres puissances halieutiques. Les aides et services qui composent ce soutien sont classés en fonction du risque qu’ils favorisent des pratiques non durables en l’absence d’une gestion efficace des pêches. En dernier lieu, les auteurs proposent des lignes d’action envisageables pour mettre fin au soutien à la pêche illicite, non déclarée et non réglementée (INN) et étudient la question de savoir comment éviter la pollution plastique des mers et océans due aux engins de pêche perdus.

The automotive sector is important across OECD countries in terms of value-added and R&D, but is also heavily affected by the green and the digital transformations. This paper offers a novel and holistic view of the automotive sector and its surrounding ecosystem based on a combination of Inter-Country Input-Output (ICIO) tables, patent data, mergers and acquisitions (M&A) transactions, cross-country micro-distributed data and firm-level balance sheet data. It identifies the boundaries of this industrial ecosystem including connected sectors (e.g. upstream and downstream) as well as knowledge and technology providers (e.g. universities or the digital industry). The paper documents emerging trends at the geographical and technological levels and provides a comprehensive assessment of the ecosystem’s changing microstructure, with a growing role of young and digital-intensive companies. Finally, it provides recommendations for effective public policies to support the automotive ecosystem, with a focus on innovation, competition and the growth of young firms.

The transition to climate neutrality requires cost reductions in existing clean technologies to enable rapid deployment on a large scale, as well as the development of emerging technologies such as green hydrogen. This policy paper argues that science, technology, innovation, and industrial (STI&I) policies focusing on developing and deploying low-carbon technologies are crucial to achieving carbon neutrality. It notes however that the current level of innovation is insufficient to meet the net-zero challenge due to a policy emphasis on deployment rather than research and development (R&D) support. The paper explores the rationale for more ambitious STI&I policies targeted at R&D for climate neutrality and provides policy recommendations for an effective innovation policy for net-zero, including its interaction with the broader climate policy package.

The economic consequences for firms investing in green innovation, and therefore their incentives to innovate, are not well understood. This paper empirically assesses the economic returns on innovation in cleaner vehicles. The analysis uses data on passenger car market shares and patents for car manufacturers operating in eight countries for the period 2005-2021. The results show that, when vehicle fuel prices increase, firms having previously successfully filed patents related to both electric and hybrid vehicles and fuel efficiency experience an increase in their market share. This increase takes place between 7 and 8 years after the patent stock is accumulated for patents related to electric and hybrid vehicles and between 8 and 15 years for patents related to fuel efficiency. The analysis also finds that in contexts where fuel price salience is high, price increases generate larger and earlier competitiveness returns for firms having previously invested in cleaner technologies.

Despite calls for the reform of incentives, including subsidies, harmful to biodiversity, including under the Convention on Biological Diversity and its 2011-2020 Aichi Targets, very few countries to date have undertaken what is considered the first step in this process, namely, to identify and assess the types and magnitudes of any incentives in place at the national level which are harmful for biodiversity or the environment more broadly. This paper begins with a brief literature review on subsidies harmful to biodiversity, followed by a detailed review and comparison of the existing national level studies to identify and assess subsidies and other incentives harmful to biodiversity or the environment. The report concludes with guidance and good practice insights to identify and assess subsidies and other incentives harmful to biodiversity, at national level.

OECD Regions and Cities at a Glance presents indicators on individual regions and cities since the turn of the new millennium. It provides a comprehensive picture of past successes and likely challenges that regions and cities in OECD members and partner countries will face in their efforts to build stronger, more sustainable and more resilient economies. By relying on a combination of traditional and more innovative data sources, OECD Regions and Cities at a Glance describes the evolving nature of spatial disparities within countries from a multidimensional perspective. New topics covered by this edition include the economic impact of recent shocks, such as the pandemic and the energy crisis, housing affordability, climate change and digitalisation.

Understanding adults’ attitudes towards the environment is necessary to gauge the opportunities and challenges of creating effective and politically-feasible climate policies. Using data from the Wellcome Global Monitor 2020, the European Social Survey (Round 8), World Values Survey and EM-DAT, this paper examines how adults’ environmental attitudes vary within and across countries and details how environmental attitudes are associated with adults’ engagement in pro-environmental behaviours and support for environmentally-friendly policies. The paper explores whether the extent to which individuals prioritise the environment over the state of the economy or vice versa depends on individuals’ exposure to natural disasters or negative labour market conditions. Results indicate that people’s economic vulnerability and the sectors they work in impact their attitudes towards their environment and support for public policy. Furthermore, the findings suggest that increases in unemployment and exposure to natural disasters influence the extent to which individuals prioritise the environment.

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 a structured and harmonised climate mitigation policy database that informs about countries’ climate action. The CAPMF was developed under the International Programme for Action on Climate (IPAC). It comprises 128 policy variables, grouped into 56 policy instruments and other climate actions, covering the 52 countries participating in IPAC and the period 2000-2020. The CAPMF is the most comprehensive internationally harmonised climate-related policy database currently available. Results indicate that IPAC countries strengthened their climate action between 2000 and 2020 in terms of both policy adoption and policy stringency, although individual countries progressed at different paces. Policy mixes in many countries changed from cross-sectoral to a more sectoral focus and from non-market to market-based approaches. Importantly, results suggest a positive relationship between stronger climate action and greater emissions reductions but further analysis is needed to fully assess policy effectiveness.

Afin de limiter les risques liés au changement climatique, la transition vers la neutralité en émission de gaz à effet de serre (GES) doit être accélérée. Les pays peuvent recourir à un large éventail d'instruments politiques pour réduire les émissions. Ce rapport montre comment les prix explicites du carbone, les taxes énergétiques et les subventions ont évolué entre 2018 et 2021. Ces instruments jouent un rôle important parmi les leviers d’action dont disposent les gouvernements. Tous les instruments présents dans le rapport ont pour effet de modifier directement le prix à payer pour émettre des GES ou de modifier les prix de l’électricité. Leur réforme peut contribuer grandement à la réalisation des objectifs climatiques tout en réduisant la pollution de l’air et de l’eau et en améliorant la situation des finances publiques. Le rapport porte sur 71 pays responsables collectivement de quelque 80 % des émissions mondiales de GES et de la consommation d’énergie. Les prix explicites du carbone et les taxes et subventions énergétiques sont détaillés par pays, secteur, produit et instrument. L’utilisation d’une méthodologie commune garantit la comparabilité entre pays. Des indicateurs synthétiques facilitent l’établissement de comparaisons et aident les décideurs publics à suivre les progrès accomplis et à repérer les possibilités de réforme.

This paper explores what the first global stocktake (GST1) under the Paris Agreement could usefully do in relation to two elements of its mandate on adaptation, namely, to review the adequacy and effectiveness of adaptation, and to enhance the implementation of adaptation action. This paper also discusses potential outputs from GST1, and how they could facilitate the intended outcomes of the process on adaptation, taking into account a learning-by-doing approach. This paper highlights that a comprehensive collective assessment of the adequacy and effectiveness of adaptation requires data that is currently not available for various reasons. Nonetheless, this paper finds that the GST’s ability to incorporate learning and its scope for continuous improvement provides an important opportunity to develop, apply and refine approaches and methodologies over time to better address the GST’s mandate on adaptation in subsequent cycles. The paper concludes that the GST1 process could help to inform and enhance Parties’ adaptation efforts by identifying priority data needs and gaps, increasing understanding of different approaches to assessing adaptation actions, identifying enabling factors for effective adaptation, and building linkages with parallel processes including on the Global Goal on Adaptation. In this way, the GST1 could play an important role in helping to set a foundation for improved approaches and data on adaptation over time that can feed into future GSTs and support the long-term goals of the Paris Agreement.

“Authorisation” is a new but as yet undefined component of the guidance for implementation of Article 6 of the Paris Agreement. Authorisation is important as it triggers both corresponding adjustments and reporting requirements. This paper identifies and analyses open questions related to what is authorised, by what process, for what purpose, the format and timing of authorisation, and how any ex-post changes to authorisation can be made. The answers to these questions can affect the attractiveness for Parties and the private sector to participate in Article 6 cooperation. The paper also outlines areas of Article 6.2 guidance that could be usefully clarified at the international level, and implications of different options for the domestic implementation of Article 6 authorisation provisions, drawing from examples of a few frontrunner Parties who have already established bilateral agreements and domestic structures for international cooperation under Article 6. The paper concludes that some of the open questions could be clarified at the international level, such as how to report any changes to authorisations and if the authorisation needs to be provided concurrently by the participating Parties. Other questions could be clarified at the national level by the participating Parties providing the authorisation. These include whether participating Parties can choose to include additional elements in their authorisations, and which roles authorised entities could play.

Water infrastructure investments are typically capital-intensive and long-lived, involving significant costs and benefits. Their performance over operational lifetimes is highly dependent on the vagaries of the hydrological cycle and subject to the risks and uncertainties associated with climate change. The challenge is to make the best use of scarce financial resources to deliver desired water services in the context of these complicating factors. Ideally, planning for water-related investments should be robust to known hazards and flexible to adapt to an uncertain future. This paper presents a conceptual and analytical framework to sequence water-related investments along “Strategic Investment Pathways”. This approach considers a range of diverse investments over multiple scenarios and evaluates options relative to stakeholder-defined goals. It explicitly considers key dynamic processes, interdependencies and feedbacks within the water system. The aim is to inform investment decisions that contribute to water system resilience through effective and adaptive management over time.
