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.

Tourism has been hit hard by the depth and duration of the crisis triggered by the COVID-19 pandemic. Just as the sector was starting to rebound, the economic fallout from Russia’s aggression against Ukraine has dealt a fresh blow to recovery prospects. The 2022 edition of OECD Tourism Trends and Policies analyses tourism performance and policy trends to support recovery across 50 OECD countries and partner economies. It examines the key tourism recovery challenges and outlook ahead, and highlights the need for co-ordinated, forward-looking policy approaches to set tourism on a path to a more resilient, sustainable and inclusive future. Evidence on the significance of the tourism economy is presented, with data covering domestic, inbound and outbound tourism, enterprises and employment, and internal tourism consumption. Tourism policy priorities, reforms and developments are analysed and examples of country practices highlighted. Thematic chapters provide insights on building resilience in the tourism ecosystem and promoting a green tourism recovery.

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.

How can fossil fuel producers and mineral-rich developing countries design realistic, just and cost-effective low-carbon transition pathways? Taking into account the heterogeneity of low-carbon trajectories, the Equitable Framework and Finance for Extractive-based Countries in Transition (EFFECT) provides options for policy makers, industry and finance institutions in search of the answers. The report aims to help them seize the transformational opportunities linked to sustainable, low-carbon growth. It identifies ways of mitigating the transition’s impacts on fossil fuel industries, workers and poor households, and of preventing the risks of high-carbon lock-in and stranded assets. Recognising the shared responsibility of consuming and producing countries in reducing fossil fuel production and use, EFFECT advocates for transformative partnerships for technology transfer, green finance and capacity building. Ultimately, it supports an equitable sharing of the transition’s benefits and costs, both across and within countries.

Building more equitable, connected, cohesive and sustainable societies is at the top of policy agendas, but several challenges stand in the way of achieving this goal. The report focuses on three key challenges policy makers face in the pursuit of better societies: bridging digital divides, combatting harmful content online, and effectively harnessing digital technologies to fight climate change and other environmental problems. This report provides insights into key trends across OECD countries and partner economies, and offers policy actions that can help decision makers tackle these three critical challenges, together with better measurement. The report builds on previous work on the topic and seeks to inform further debate and discussion on how to ensure that today’s divides, biases and inequalities are not perpetuated into the future.

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.
