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.
