In spite of progress made to date and the significant long-term ambition announced by many countries, climate policy actions remain insufficient to meet the Paris Agreement objectives. While several international initiatives aim to track and monitor climate policies, there is not yet a 'go to' place for a comprehensive inventory of policy actions and best practices worldwide. Such a platform would also ideally serve to compare policies’ effectiveness reflecting the diversity of country circumstances. Progress in this direction would help to promote an ambitious but globally more coherent and better-coordinated approach to emission reductions through a broad range of policies. This report lays out a roadmap for data and analytical work to support this aim, with a view to enhancing global dialogue and building trust on issues spanning climate change mitigation policies and their macro-economic repercussions. Key elements to strengthen the assessment and comparison of countries’ climate change mitigation policies across countries include: broadening and deepening the stocktaking of mitigation policies; extending and agreeing on an operational methodology for estimating the impact of these policies on emissions and on potential metrics to compare them; and assessing the broader economic effects of different climate policies.

Construire des sociétés plus équitables, connectées, cohésives et durables figure en tête des priorités politiques, mais plusieurs défis se dressent sur la voie de la réalisation de cet objectif. Le rapport se concentre sur trois défis clés auxquels les décideurs sont confrontés dans la quête de sociétés meilleures : combler les fractures numériques, lutter contre les contenus préjudiciables diffusés en ligne et utiliser efficacement les technologies numériques pour lutter contre le changement climatique et d'autres problèmes environnementaux. Ce rapport donne un aperçu des tendances clés dans les pays de l'OCDE et les économies partenaires, et propose des actions politiques qui peuvent aider les décideurs à aborder ces trois défis critiques, ainsi qu'une meilleure mesure. Le rapport s'appuie sur des travaux antérieurs sur le sujet et vise à éclairer le débat et la discussion sur la manière de garantir que les fractures, biais et inégalités d'aujourd'hui ne se perpétueront pas à l'avenir.

This report reviews evidence that overshooting 1.5°C may push the earth over several tipping points, leading to irreversible and severe changes in the climate system. If triggered, tipping point impacts will rapidly cascade through socio-economic and ecological systems, leading to severe effects on human and natural systems and imposing important challenges for human adaptation. Of particular concern are the likely collapse of the West Antarctic and Greenland ice sheets and the abrupt melting of permafrost grounds in the Arctic, which would result in additional sea-level rise and greenhouse gas releases, leading to more warming. Based on the most recent science and consultations with renowned experts, Climate Tipping Points: Insights for Effective Policy Action argues that it is no longer appropriate to consider the risk of crossing tipping points as low-probability. Overshooting 1.5°C may likely lead to irreversible and severe impacts, which must be avoided, heightening the urgency to drastically reduce emissions within this decade. The report calls for a shift in how tipping points are treated in climate policy today and provides recommendations on how climate risk management strategies can better reflect the risks of tipping points in the areas of mitigation, adaptation and technological innovation.

The consequences of climate change in developing countries are worsening fast: many ecosystems will shortly reach points of irreversible damage, and socio-economic costs will continue to rise. To alleviate the future impacts on populations and economies, policy makers are looking for the spaces where they can make the greatest difference. This report argues that intermediary cities in developing countries are such spaces. Indeed, in the context of fast population growth and urbanisation, these small and medium-sized cities silently play an essential role in the rapid transformation of human settlements, not least by supporting the massive flows of population, goods and services between rural and metropolitan areas. Most of those intermediary cities are still growing: now is therefore the time to influence their dynamics, and thereby the entire design of urbanisation in those regions, in ways that limit the exposure of urban dwellers to climate shocks and avoid carbon lock-in. To that end, based on fresh evidence and policy analysis on the challenges faced by these agglomerations in the context of climate change, the report makes the case for new development approaches to avoid the unsustainable paths followed by too many cities in the recent past.

Artificial intelligence (AI) systems can use massive computational resources, raising sustainability concerns. This report aims to improve understanding of the environmental impacts of AI, and help measure and decrease AI’s negative effects while enabling it to accelerate action for the good of the planet. It distinguishes between the direct environmental impacts of developing, using and disposing of AI systems and related equipment, and the indirect costs and benefits of using AI applications. It recommends the establishment of measurement standards, expanding data collection, identifying AI-specific impacts, looking beyond operational energy use and emissions, and improving transparency and equity to help policy makers make AI part of the solution to sustainability challenges.

India has achieved major progress in its energy sector over the last two decades. Still, investment needs to scale up considerably to meet the government’s ambitions to achieve 500 GW of renewable energy capacity and energy-intensity reductions of 45% by 2030. Targeted application of public funds, alongside international climate and development finance, can crowd in investors and channel private capital to meet India’s clean energy goals. The Clean Energy Finance and Investment Roadmap of India highlights key actions needed to accelerate the development of energy efficiency measures in micro, small and medium enterprises, offshore wind and green hydrogen production. The report provides a comprehensive overview of the initiatives to date and challenges to scale up investments. It also provides a number of tailored recommendations for the Government of India, development partners and the private sector.

The communication sector is undergoing high-paced developments driven by the digital transformation of our economies and societies. Technological convergence has led to an evolving competitive landscape and new challenges arise around privacy and security concerns. Communication regulators are increasingly acknowledging the positive and negative effects of communication infrastructures and services on the environment. Moreover, there is a growing need to ensure the resilience of networks, stemming partially from the effects of climate change. In consequence, the key question for OECD policymakers is no longer whether regulatory structures need to change, but rather how. This report explores the critical role communication regulators play in an increasingly connected society. It identifies the challenges stemming from the digital transformation of our societies, the main policy objectives pursued by communication regulators, measures to address current and future challenges, as well as the importance of strengthening the capabilities of communication regulators of the future.

Spectrum is a limited national resource that enables our digital world. Mobile broadband services rely on these invisible airwaves to function, making spectrum indispensable to bridge connectivity divides. It also supports the provision of wireless services across the economy, from education to healthcare to industry, and enables applications such as satellites, GPS and the Internet of Things. Spectrum must be efficiently managed to achieve broader social and economic goals. As such, the stakes of spectrum management decisions are high and the challenges complex. This report discusses the effective stewardship of this essential asset in the context of wireless communication services, presents trends in policy, and discusses future considerations for management. It finds that well-designed and transparent licensing regimes, including auctions, foster investment and innovation, and that flexible frameworks (e.g. sharing or unlicensed spectrum) can promote efficient use.

Small island developing states (SIDS) have been acutely affected by the economic impacts of the COVID-19 pandemic. This paper takes a broader perspective to explore how the revenue effects of this crisis in SIDS are connected to their unique financing and development challenges. It also suggests how SIDS governments and development co-operation providers can better partner together to strengthen mobilisation of domestic revenues – in particular tax revenues – in the recovery post-COVID-19.

Since the 1990’s, the countries of Eastern Europe, the Caucasus and Central Asia (EECCA) have made great progress in pursuing economic development that is also environmentally sustainable. The countries, in collaboration with the GREEN Action Task Force hosted by the OECD, has developed a number of policies aiming to improve environmental quality and social well-being, while creating opportunities for strong economic growth and decent jobs in the region. This report was prepared as the OECD contribution to the ninth 'Environment for Europe' (EfE) Conference (5-7 October 2022). In this context, this report aims to: (i) take stock of progress on policy developments towards a green economy in the EECCA countries; (ii) showcase selected contributions from of the Green Action Task Force that integrate environmental and climate considerations into development pathways of the EECCA countries, and mobilise finance for action; and (iii) provide an outlook for the future, including priority actions that the Task Force in co-operation with the EECCA countries should take to enhance the momentum for green economy transition in the region.
