Première économie mondiale, les États-Unis ont progressé dans la réduction de plusieurs pressions environnementales tout en conservant l’un des produits intérieurs bruts par habitant les plus élevés au monde. Les émissions de gaz à effet de serre et de polluants atmosphériques, les prélèvements d’eau et la consommation intérieure de matières y ont été découplés de la croissance économique et démographique. Les niveaux de consommation élevés, les pratiques agricoles intensives, le changement climatique et l’étalement urbain continuent toutefois d’exercer des pressions sur le milieu naturel. Malgré l’accélération récente de l’action publique face au changement climatique, des efforts supplémentaires sont nécessaires pour atteindre l’objectif de neutralité en gaz à effet de serre d’ici à 2050. Par ailleurs, les États-Unis figurent parmi les principaux producteurs de déchets marins, lesquels ont de graves conséquences pour les populations et l’environnement. Le présent rapport contient 30 recommandations visant à aider les États-Unis à améliorer leurs performances environnementales, et accorde une attention particulière à l’enjeu des déchets marins et à la problématique transversale de la justice environnementale. Troisième Examen environnemental consacré aux États‑Unis, il propose une évaluation indépendante, fondée sur des données factuelles, des performances environnementales du pays au cours de la dernière décennie. La présente version abrégée contient le résumé, de même que l’évaluation et les recommandations officielles du rapport. Le rapport complet est disponible en anglais sur le site Internet de l’OCDE.

La rapide croissance économique et démographique que connaît Israël et son fort degré d’urbanisation continuent d’exercer des pressions significatives sur l’environnement. Le pays a relevé ses ambitions en matière de climat ces dernières années, mais n’est pas parti pour atteindre ses objectifs de réduction des émissions de gaz à effet de serre. De nouvelles mesures s’imposent pour mieux protéger la biodiversité, combattre la pollution de l’eau et s’adapter aux effets du changement climatique. Israël a pris une série de mesures importantes au service de ses ambitions de réduction à zéro des déchets et de circularité de l’économie. Il doit toutefois redoubler d’efforts pour améliorer la gestion des déchets et mettre l’économie dans son ensemble sur la voie de la circularité. L’examen formule 24 recommandations qui visent à aider Israël à améliorer ses performances environnementales, et accorde une attention particulière à la gestion des déchets et à l’économie circulaire. Avec ce deuxième Examen environnemental d’Israël, l’OCDE propose une évaluation indépendante, fondée sur des données factuelles, des performances environnementales du pays au cours de la dernière décennie. La présente version abrégée contient le résumé, de même que l’évaluation et les recommandations officielles du rapport. Le rapport complet est disponible en anglais sur le site web de l’OCDE.

The paper presents the understanding of and attitudes towards climate change and climate policies in Ukraine, using a survey on a representative sample of more than 1 500 Ukrainians. The survey was carried out between October 2021 and February 2022 and presents the situation before Russia’s large-scale invasion of Ukraine. The survey tests support for three main climate policies in detail: a green infrastructure programme, a carbon tax with cash transfers and a ban on combustion-engine cars. It shows that support for climate policies depends on three key factors: how people perceive the effectiveness of the policies in reducing emissions, how they perceive distributional impacts on lower-income households (inequality concerns), and if they think their household will gain or lose from the policy. The survey also shows that when citizens receive information that specifically addresses these concerns, they exhibit stronger support for the policy. How the policy is designed also matters: Ukrainians widely accept a carbon tax when its revenues finance green investments and/or compensate lower-income households. The paper highlights seven considerations for Ukraine policymakers to design measures that are effective and supported by citizens. Following Russia’s war of aggression and once conditions are right, Ukrainian policymakers can also use the survey results to guide the reform of the environmental tax system- one of the goals in Ukraine’s recovery and reform agenda. The survey in Ukraine that the paper describes was conducted as part of a large-scale OECD international survey of attitudes toward climate policies carried out on over 40 000 respondents in twenty countries.

This new web format for Country Notes on Fossil Fuel Support provides interactive on-line access to the latest data from the OECD Inventory of Support Measures for Fossil Fuels by country – identifying and estimating the value of support arising from policies that encourage the production or consumption of fossil fuels. The web version allows users to download, share and play with the data. Interactive graphics enable data visualisation, in national currency, by beneficiary and by energy product. These Country Notes provide, for each of the 50 economies covered in the Inventory, a snapshot of energy market structure, the current state of energy prices and taxes, and recent developments and trends in fossil fuel support. Data and country notes for the EU Eastern Partnership (EaP) countries have been collected and prepared as part of the GREEN Action Task Force.

The SME Policy Index: Eastern Partner Countries 2024 – Building resilience in challenging times is a unique benchmarking tool to assess and monitor progress in the design and implementation of SME policies against EU and international best practice. It embraces the priorities laid out in the European Union’s SME Strategy for a sustainable and digital Europe and is structured around the ten principles of the Small Business Act for Europe, which provide a wide range of measures to guide the design and implementation of SME policies. This report marks the fourth edition in this series, following assessments in 2012, 2016, and 2020. It tracks progress made since 2020 and offers the latest key findings on SME development and related policies in the countries of the Eastern Partnership (EaP). It also identifies emerging challenges affecting SMEs in the region and provides recommendations to address them. The 2024 edition benefits from an updated methodology that also offers a deeper analysis of policies to support the digital transformation of SMEs.

This adverse outcome pathway links inhibition of aromatase activity in teleost fish during gonadogenesis to increased differentiation to testis resulting in a male-biased sex ratio in the population, and ultimately, reduced population sustainability. Most gonochoristic fish species develop either as males or females and do not change sex throughout their life span. However, in species where sexual differentiation is controlled at least to some degree by environmental factors, there can be a window of development during gonadal differentiation that is sensitive to a variety of exogenous conditions. During this window, endocrine active chemicals, aromatase inhibitors in particular, have the potential to alter gonad development and sex differentiation. This AOP is referred to as AOP 346 in the Collaborative Adverse Outcome Pathway Wiki (AOP-Wiki).

This adverse outcome pathway links androgen receptor agonism in teleost fish during gonadogenesis to male-biased sexual differentiation and consequently, reduced population growth rate. Sex determination in teleost fishes is highly plastic; it can be genetically or environmentally influenced. Species with environmentally-based sex determination in particular can be very sensitive to exogenous chemicals during the period of differentiation. Exogenous hormones are of ecological concern because they have the potential to alter gonad development and sex differentiation. This AOP is referred to as AOP 376 in the Collaborative Adverse Outcome Pathway Wiki (AOP-Wiki).

This study evaluates the progress of fossil-fuel subsidy reform in Ukraine since its launch in 2016 using the OECD 'bottom-up', inventory, approach. It also identifies major subsidy schemes that need significant reform. The report reflects the energy subsidy policies and reforms in Ukraine prior to Russia’s full-scale invasion in February 2022. The analysis covers: budgetary transfers, government revenue foregone (or tax expenditure), induced transfers in the form of cross-subsidies or below market tariffs and transfer of risk to government. The study also covers fossil-fuels subsidies to production and consumption, particularly, for natural gas, coal and electricity generated from fossil fuels while support for energy efficiency and renewables is considered for comparative purposes. This report also briefly discusses the taxation and energy pricing policies in Ukraine that have had direct or indirect impact on the evolution of fossil-fuel subsidies in the country. Detailed estimates of all individual support measures are provided in the Annexes to the report.

Lung fibrosis is a dysregulated or exaggerated tissue repair process resulting in the thickening or scarring of lung tissue. It involves the presence of sustained or repeated exposure to a stressor and intricate dynamics between several inflammatory and immune response cells, and the microenvironment of the alveolar-capillary region consisting of both immune and non-immune cells, and the lung interstitium. This AOP is applicable to a broad group of stressors of diverse properties e.g. metal dusts, pharmacological products, fibres, microorganisms, chemicals, including novel technology-enabled stressors such as nanomaterials. This AOP is referred to as AOP 173 in the Collaborative Adverse Outcome Pathway Wiki (AOP-Wiki).

The scale of Uzbekistan’s green transition requires a marked increase in private financing to fill the existing spending gap. The outsized role of the state in Uzbekistan’s economy and its underdeveloped domestic capital market act as significant constraints and call for a diversification of sources to finance the green transition. Since 2021, Uzbekistan has made green bonds a central part of its strategy to fill the financing gap and mobilise new sources of capital for its domestic green infrastructure projects. This publication explores the current market and institutional set-up in Uzbekistan, the reforms that have led to recent issuances of both sovereign and corporate thematic bonds, and the remaining barriers to further uptake of the instrument. The report also provides policy recommendations related to the market's institutional set up, Uzbekistan's regulatory framework for debt capital markets and emerging opportunities for further green bond use aimed at key stakeholders, including policy makers and market participants.
