The rapid advances of artificial intelligence (AI) in recent years have led to numerous creative applications in science. Accelerating the productivity of science could be the most economically and socially valuable of all the uses of AI. Utilising AI to accelerate scientific productivity will support the ability of OECD countries to grow, innovate and meet global challenges, from climate change to new contagions. This publication is aimed at a broad readership, including policy makers, the public, and stakeholders in all areas of science. It is written in non-technical language and gathers the perspectives of prominent researchers and practitioners. The book examines various topics, including the current, emerging, and potential future uses of AI in science, where progress is needed to better serve scientific advancements, and changes in scientific productivity. Additionally, it explores measures to expedite the integration of AI into research in developing countries. A distinctive contribution is the book’s examination of policies for AI in science. Policy makers and actors across research systems can do much to deepen AI’s use in science, magnifying its positive effects, while adapting to the fast-changing implications of AI for research governance.

This paper investigates the role of fiscal federalism in driving ecological transition, a key challenge in the United Nations’ Sustainable Development Goals agenda. The ecological transition seeks a sustainable society that prioritises natural resource preservation and reduces environmental impacts. The study investigates the link between fiscal federalism institutions and ecological transition policies, focusing on regional and local governments’ role in implementing environmental goals. Despite subnational governments’ commitment to green objectives, comprehensive plan implementation has been limited due to local governments’ incentive schemes and capacity constraints. The paper examines the potential of fiscal federalism institutions, such as fiscal rules, transfers and capacity-building programs, to support ecological transition policies. The research emphasises engaging regional and local governments in the green agenda and highlights the need for tailored approaches in multi-level fiscal governance to effectively achieve environmental goals. By investigating fiscal federalism’s potential contribution to ecological transition, the paper offers valuable insights for policymakers addressing environmental challenges through a multi-level governance approach.

The System of Environmental Economic Accounting Central Framework (SEEA CF) was adopted in 2012. In one decade, it has expanded to 92 countries, including most OECD countries. However, there is still work to be done by national statistics producers to increase the use of SEEA statistics. This paper focuses on the SEEA stocks and flows accounts, providing examples of where they are already used to support public policy making in high-priority areas such as climate change, environmental sustainability, the circular economy, and management of ecosystems and freshwater, as well as feeding into indicators, dashboards and other frameworks. Although these examples show that SEEA statistics are already informing public policy making in many countries, there are still important 'influence gaps'. The second part of this paper discusses why these gaps exist and what can be done about them.

The United States, the world’s largest economy, has made progress in reducing several environmental pressures while maintaining one of the highest Gross Domestic Products per capita in the world. It has decoupled emissions of greenhouse gases, air pollutants, water abstractions and domestic material consumption from economic and population growth. However, high consumption levels, intensive agricultural practices, climate change and urban sprawl continue to put pressure on the natural environment. Despite the recent acceleration of action to address climate change, further efforts are needed to achieve the goal of net-zero greenhouse gas emissions by 2050. The United States is also among the major contributors to marine litter with serious consequences for communities and the environment. The review provides 30 recommendations to help the United States improve its environmental performance, with a special focus on marine litter and a cross-cutting focus on environmental justice. This is the third Environmental Performance Review of the United States. It provides an independent, evidence-based evaluation of the country’s environmental performance over the past decade.

This report presents the policy recommendations resulting from the National Dialogue on Water in Indonesia, which took place between June 2022 and March 2023. Getting water resources management right, underpinned with appropriate financing mechanisms, is a prerequisite for realising Indonesia’s ambitious national economic growth agenda to become one of the top five global economies by 2045. The Dialogue, therefore, centred around two priority areas: 1) financing water infrastructure and 2) non-structural measures for flood disaster risk reduction. The report explores several instruments to enhance the financing of water services in Indonesia, such as the advantages and disadvantages of uniform water tariffs, independent economic regulation, pollution charges and demand management instruments. The report recommends the utilisation of land value capture as an additional source of financing. It also explores how water information systems for disaster response, flood forecasting and early warning can reduce flood disaster risk. The National Dialogue on Water in Indonesia is part of a regional initiative with the Ministry of Environment of the Republic of Korea, the Asia Water Council and the OECD.

Expanding on the findings of Brick by Brick: Better Housing Policies, this second volume delves into key trends shaping housing policies in the post-COVID-19 era. The first chapter provides an overview and discusses the need to monitor the pandemic's impacts on housing affordability, address the energy crisis through low-carbon housing initiatives, maintain financial resilience amid fluctuating housing cycles, and facilitate the reshaping of housing markets in response to remote work and environmental concerns. The second chapter focuses on the decarbonisation of the housing sector. It recommends a mix of carbon pricing, energy-efficiency certification and regulation, and subsidies to meet net-zero targets while accounting for housing market specificities. The chapter also calls for deploying complementary policies to limit adverse impacts on low-income households. The third chapter examines housing finance, focusing on the tension between supporting mortgage borrowing and promoting financial resilience. It also discusses the rise of non-bank real estate finance and the potential for mortgage finance to support housing decarbonisation. The fourth chapter explores how the new work-life balance, enabled by the rise of remote work, is reshaping housing demand and proposes a set of tailored urban policies to address this shift. Overall, the report provides a comprehensive blueprint for housing policies in the post-pandemic world.

This paper explores the nexus between decarbonisation and intergovernmental fiscal relations, focusing on related challenges and reform options. It highlights the significant role of subnational governments in tackling climate change. Subnational and national governments share responsibilities in areas such as taxation, spending and regulation pertaining to environmental protection, as well as climate change mitigation and adaptation, which calls for effective intergovernmental co-operation to align policy objectives and implementation strategies. The paper outlines decarbonisation requirements across sectors and discusses subnational government involvement in service delivery, investment, revenue generation and regulatory frameworks. Policy options to strengthen subnational contributions to national decarbonisation goals are presented. While focusing primarily on OECD countries, the paper acknowledges the need for improved information on subnational decarbonisation efforts in both advanced and developing countries.

Israel’s rapid economic and population growth along with a high degree of urbanisation continue to exert significant pressure on the environment. Israel has raised its climate ambitions in recent years, though is not on track to reach greenhouse gas reduction targets. Enhancing biodiversity protection, addressing water pollution and adapting to the impacts of climate change require further action. Israel has taken a number of key steps to advance its zero waste and circular economy agenda. However, further efforts are required to improve waste management and introduce an economy-wide shift to a circular economy. The review provides 24 recommendations to help Israel improve its environmental performance, with a special focus on waste management and circular economy. This is the second Environmental Performance Review of Israel. It provides an independent, evidence-based evaluation of the country’s environmental performance over the past decade.

Colombia has prioritised the use of renewable energy to expand and improve electricity services for its population in zones non-interconnected to the national grid. Recent policies and regulations have supported this ambition with successive measures to strengthen investment conditions for distributed renewable energy, like standalone solar photovoltaic (PV) solutions and hybrid solar PV mini-grids. Still, the distributed renewable energy market in non-interconnected zones is relatively immature, reflected by the high costs for connecting new users. New business and financing models will be critical to bringing down the cost of renewable energy technologies, accessing private equity and debt in larger volumes, and ultimately progressing towards replacing existing inefficient and polluting diesel generation systems. Building on international experiences, this paper discusses approaches to strengthening investment conditions, looking at support mechanisms and de-risking instruments used elsewhere, which can help bridge the financing gap in Colombia.

Germany has continued to improve its environmental performance over the past decade. It has ambitious climate targets with the aim to reach climate neutrality by 2045 and achieve negative emissions after 2050. Nevertheless, Germany will need to further accelerate climate action, particularly in the buildings and transport sectors, and address the triple crisis of energy, climate and biodiversity in an integrated and holistic manner. As part of its energy crisis response, Germany has taken a series of measures, which are historic in size and scope. They are set to massively accelerate its green energy transition in the coming years. It is also scaling up its engagement on climate change adaptation across all government levels and has initiated an ambitious programme to foster investments in nature-based solutions. This is the fourth OECD Environmental Performance Review of Germany. It provides 28 recommendations to help Germany further improve its environmental performance.
