The Slovak Republic has reduced some environmental pressures over the past decade. However, it needs to do more to reduce air pollution, improve waste and wastewater treatment and move towards carbon neutrality. Since 2011, the country has taken important steps to improve its biodiversity policy. Slovakia needs to now align its strategy with the Kunming-Montreal Global Biodiversity Framework and the EU Biodiversity Strategy for 2030. Most species and habitats are in an unfavourable state and biodiversity considerations are not sufficiently integrated into sectoral policies.

This is the third Environmental Performance Review of the Slovak Republic. It provides an evidence-based assessment of the country's progress towards its environmental goals over the past decade. The 29 recommendations aim to help Slovakia improve its environmental performance, giving special focus to biodiversity and forests in the context of climate change.

Chile has made important strides on its environmental agenda in recent years with the passage of the Framework Law on Climate Change, the establishment of the Biodiversity and Protected Areas Service and the ratification of the Escazú Agreement. However, the country has made limited progress in decoupling environmental pressures from economic growth. Greenhouse gas emissions have continued to rise and the country is not on track to reach its legally binding target of net zero by 2050. Chile is well-positioned to achieve its targets for biodiversity, while air pollution remains a serious public health challenge and waste management relies heavily on landfilling. Chile is facing a severe and deepening water crisis that requires concerted action to improve water allocation and water quality, and to strengthen water governance. The review provides 36 recommendations to help Chile improve its environmental performance, with a special focus on water management and policies.

This is the third Environmental Performance Review of Chile. It provides an independent, evidence-based evaluation of the country’s environmental performance since the previous review in 2016.

A megadiverse county, Costa Rica is known globally for its success in reversing deforestation and pursuing a growth model based on the sustainable use of its environmental resources. However, energy use and related greenhouse gas emissions increased in the last decade. Private cars are a major and growing source of emissions affecting climate and air quality. Waste disposal still relies on landfills, and much wastewater is untreated. Costa Rica’s extensive protected area network and pioneering programme of payments for ecosystem services have helped reduce biodiversity loss and extend forests’ carbon sequestration capacity. However, more should be done to tackle pressures on biodiversity from development of infrastructure and settlements, tourism, farming and fishing. The sheer scale of investment needed to achieve the Sustainable Development Goals calls for improving the efficiency of public spending, mobilising private finance, strictly enforcing regulations and providing adequate incentives.

This is the first OECD Environmental Performance Review of Costa Rica. It evaluates the country’s progress towards sustainable development, with a special chapter focusing on biodiversity, and provides 52 recommendations.

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.

The global energy crisis has moved energy security to the fore of the international policy agenda and boosted the momentum behind the deployment of clean energy technologies. Investment in clean energy is accelerating at a faster rate than for fossil fuels, helping bring peak oil demand into view. Oil 2023, the IEA’s medium‑term outlook, provides a comprehensive overview of evolving oil supply and demand dynamics through to 2028.

The report examines how a stronger drive by governments towards a low-emissions future and changes in behaviour will impact oil market fundamentals in the coming years. Oil 2023 explores some of the challenges and uncertainties that lie ahead, including upstream investment, sources of new supply growth, spare capacity and shifting patterns of oil demand. It also provides insights as to how these changing dynamics will affect refining and trade flows.

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.

Portugal managed to decouple several environmental pressures from economic growth over 2013-19. It played a leading role in the approval of the European Climate Law and adopted the Portuguese Framework Climate Law in 2021. This needs to be swiftly implemented to achieve carbon neutrality by 2050, improve climate resilience and protect ecosystems. Portugal has stepped up adaptation efforts but needs to do more to address multiple threats, including coastal erosion, floods, droughts and forest fires. The country is lagging behind in waste management. Meanwhile, the increase in freshwater abstractions in water-scarce southern regions is a concern.

This is the fourth Environmental Performance Review of Portugal. It provides an evidence-based assessment of the country's progress towards its environmental goals over the past decade. The 26 recommendations aim to help Portugal improve its environmental performance, giving special focus to carbon neutrality.

Hydrogen and carbon capture, utilisation, and storage (CCUS) are set to play important and complementary roles in meeting People’s Republic of China’s (hereafter, “China”) pledge to peak carbon dioxide emissions before 2030 and achieve carbon neutrality before 2060. Hydrogen could contribute to China’s energy system decarbonisation strategy, such as through the use as a fuel and feedstock in industrial processes; in fuel cell electric transport, and for the production of synthetic hydrocarbon fuels for shipping and aviation. The analysis of scenarios in this report suggests that while hydrogen from renewable power electrolysis could meet the majority of hydrogen demand by 2060, equipping existing hydrogen production facilities with CCUS could be a complementary strategy to reduce emissions and scale-up low-emission hydrogen supply.

This report was produced in collaboration with the Administrative Centre for China’s Agenda 21 (ACCA21). It explores today’s hydrogen and CCUS status in China, and the potential evolution of hydrogen demand in various sectors of the Chinese economy through 2060, in light of scenarios developed independently by the IEA and the China Hydrogen Alliance. The report also provides a comparative assessment of the economic performance and life cycle emissions of different hydrogen production routes. Finally, the report discusses potential synergies and regional opportunities in deploying CCUS and hydrogen, and identifies financing mechanisms and supporting policies required to enable the deployment of hydrogen production with CCUS in China.

Over the past decade, the United Kingdom has reduced several environmental pressures while growing its economy. Ahead of its presidency of the 2021 UN Climate Change Conference of the Parties, it has led the way by raising its national ambition. However, air pollution, deteriorating natural assets and missed biodiversity targets are all concerns. Further efforts are needed to achieve net zero greenhouse gas emissions by 2050, prepare for climate change, reverse biodiversity loss and ensure a more resource-efficient circular economy. Strengthening co‑ordination between the United Kingdom and devolved governments, as well as enhancing coherence between sectoral and environmental policies will be key.

This is the third Environmental Performance Review of the United Kingdom. It evaluates progress towards green growth, with a special chapter focusing on waste, materials management and the circular economy.

Norway has made progress on the path towards green growth over the past decade. The country is a frontrunner in many environmental areas and invests heavily in technological development and innovation to support its green transition. It set many ambitious national environmental targets across all sectors, including for climate mitigation; Norway aims to achieve climate neutrality by 2030. While not a member of the European Union, Norway has aligned its action with many EU regulations and goals, sometimes more stringently than members. Despite progress in many areas, the country still faces multiple challenges, including sustainable consumption patterns and biodiversity protection. The review provides 30 recommendations to help Norway further improve its environmental performance, with a special focus on sustainable land use and biodiversity management.

This is the fourth Environmental Performance Review of Norway. It provides an independent, evidence-based evaluation of the country’s environmental performance over the past decade.

Finland has a strong reputation as a leader in environmental policy and sustainable development. It committed to become carbon neutral by 2035 and to pioneer the world’s first circular economy. However, it is not fully on track to meet its ambitious goals. Greenhouse gas emissions fell in the last decade, but they need to decline at a much faster pace to meet the target. Waste generation, material consumption and nutrient losses to water bodies have continued to rise. Agriculture and a large forestry sector exert pressures on the country’s biodiversity. Targeted policy measures are needed to provide adequate incentives, boost investment and innovation and steer the economic recovery from the COVID-19 crisis towards the green transition. Finland should move from good strategy making to effective and coherent implementation. It needs to get the right policies in place, to secure sufficient resources and ensure continued and broad public consensus.

This is the third Environmental Performance Review of Finland. It evaluates progress towards green growth and sustainable development, with a special chapter focusing on climate change mitigation and well-being.

Lithuania’s rapid economic growth has increased many environmental pressures. The country has declared ambitious medium- and long-term climate change mitigation goals. However, existing policies will not be enough to meet them. Total greenhouse gas emissions have not declined over the last decade, while those from transport have been rising rapidly. Lithuania needs to build on its impressive progress in moving away from landfilling to reduce waste generation and steer towards a circular economy. Water pollution with nutrients from the increased use of fertilisers and insufficiently treated wastewater must also be addressed. These efforts require improved integration of environmental considerations into sectoral policies and a whole-of-government approach to environmental management.

Lithuania is implementing a series of positive changes in environment-related taxation. However, the trend of declining public environmental expenditure should be reversed. One priority area is additional investment in public transport and improvements in cycling and walking conditions that would help steer user behaviour towards sustainable transport modes.

This is the first OECD Environmental Performance Review of Lithuania. It evaluates progress towards green growth and sustainable development, with a special chapter focusing on sustainable mobility.
