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.

Ireland’s progress in delinking the economy from environmental pressures has been uneven in the last decade. Greenhouse gas emissions, waste generation and nutrient pollution rose with strong economic growth between the mid-2010s and the inception of the COVID‑19 pandemic. The country’s dispersed settlement pattern implies that roads are the dominant transport mode. Climate, circular economy and biodiversity policies have gained renewed impetus, with various ambitious policy initiatives and large public investment plans. These need to be swiftly implemented to alleviate the growing pressures from intensification of agricultural practices, demographic development, urban sprawl and road traffic. Encouraging businesses and households to take action is key. This requires providing consistent price signals for the use of energy and natural resources and for better managing travel demand, while taking into account affordability, employment impact and regional disparities. This is the third Environmental Performance Review of Ireland. It evaluates progress towards green growth and sustainable development, with a special chapter focusing on sustainable mobility and freight.

Belgium has made progress in decoupling several environmental pressures from economic growth, in improving wastewater treatment and in expanding protected areas. Regions have achieved high levels of recovery and recycling, and have pioneered circular economy policies. However, further efforts are needed to progress towards carbon neutrality, reduce air and water pollution, reverse biodiversity loss and consolidate results of circular economy initiatives. Strengthening co‑ordination between the federal government and the regions, and among the regions, as well as enhancing policy coherence will be key factors of progress. As the COVID-19 emergency passes, recovery efforts should focus on putting the country back on track to meet the Sustainable Development Goals. Investing in low-carbon and natural infrastructure, promoting circular economy, strengthening carbon prices and phasing out environmentally harmful subsidies should be priorities. This is the third Environmental Performance Review of Belgium. It evaluates progress towards sustainable development and green growth, with special features on biodiversity and waste, materials management and the circular economy.

Luxembourg has made progress in decoupling environmental pressures from economic growth, treating wastewater and managing waste and materials. It has also positioned itself as an international centre for green finance. Yet, it remains one of the most carbon- and material-intensive economies in the OECD. The country is a crossroads for freight traffic and attracts thousands of daily cross-border commuters. This exacerbates greenhouse gas emissions, air pollution and road congestion. Urban sprawl, landscape fragmentation and agriculture exert strong pressures on biodiversity. To steer its economy towards a greener model, Luxembourg has set ambitious environmental objectives. Greening taxation, providing stronger price signals, promoting eco-innovation and the circular economy, mainstreaming biodiversity into all policies, and investing in low-carbon infrastructure and sustainable mobility, should be priorities. This is the third Environmental Performance Review of Luxembourg. It evaluates progress towards green growth and sustainable development, with special chapters focusing on two major issues: air quality and mobility, and biodiversity.

Greece has undergone extensive reforms to cope with a deep recession over the past decade. It has made progress in decoupling air pollutant emissions from GDP and improving the conservation status of natural habitats. However, the country faces challenges in managing waste and water, and addressing air pollution. It is highly vulnerable to the impact of climate change. The energy mix has shifted towards cleaner fuels, but the economy strongly relies on fossil fuels. Progress towards sustainable development requires effective implementation of ambitious climate mitigation and adaptation policies, strengthening environmental governance and enhancing coherence between environmental and energy, transport, agriculture and tourism policies. This is the third Environmental Performance Review of Greece. It evaluates progress towards sustainable development and green growth, with special features on climate change mitigation and adaptation, and biodiversity conservation and sustainable use.

Denmark's energy and carbon intensities are among the lowest in the OECD area. Green taxation as a share of GDP is the highest in the OECD, and the country is a leader in eco-innovation. Denmark has also achieved impressive results in the material recovery of most waste streams and reached a political agreement to move to a circular economy. It is an international standard setter for chemical risk assessment. However, municipal waste generation remains the highest in the OECD area. Many bodies of water do not reach good ecological status. Levels of exposure to fine particles remain above international standards. Terrestrial biodiversity suffers from the lack of well-connected protected areas. Further steps will need to be taken to achieve the stated goal of a climate neutral economy by 2050. This is the third Environmental Performance Review of Denmark. It evaluates progress towards sustainable development and green growth, with special features on waste, materials management and the circular economy and chemicals management.

Latvia has come a long way in improving its environmental performance and the well-being of the population. Large amounts of investment have helped increase the use of renewables, improve energy efficiency of homes, reduce greenhouse gas emissions and extend access to water and waste services. However, convergence with more advanced OECD economies is far from being accomplished. Forestry and agriculture play a key economic role, but exert increasing pressures on biodiversity. Mainstreaming biodiversity considerations into economic development policies should be a priority. Accelerating the transition towards a low-carbon and circular economy will require major investment in sustainable infrastructure, more waste prevention and recycling and stronger economic instruments. This is the first Environmental Performance Review of Latvia. It evaluates progress towards sustainable development and green growth, with special features on waste and circular economy, and biodiversity conservation and sustainable use.

This report provides a cross-country review of waste, materials management and circular economy policies in selected OECD countries, drawing on OECD’s Environmental Performance Reviews during the period 2010-17. It presents the main achievements in the countries reviewed, along with common trends and policy challenges, and provides insights into the effectiveness and efficiency of waste, materials management and circular economy policy frameworks. As the selected reviews were published over a seven-year period, information for some countries may be more recent than for others. Nevertheless, the policy recommendations emerging from the reviews may provide useful lessons for other OECD countries and partner economies.

Indonesia is the world’s fourth most populated country, and the largest archipelagic one. Vibrant economic growth has lifted millions of people out of poverty. Economic success, however, has come at a high environmental cost. Rapid land-use change and reliance on fossil energy make Indonesia one of the world’s largest greenhouse gas emitters. Deforestation and pollution are putting pressure on its megadiverse ecosystems. Environmental services such as water supply, sanitation and waste management need to be further expanded and improved. Advancing to a greener economy will require continued efforts to develop policies, strengthen institutions and secure sufficient resources. This is the first Green Growth Policy Review of Indonesia. It examines progress towards sustainable development and green growth, with a special emphasis on the nexus of land use, ecosystems and climate change.
