Finland’s forests, once a crucial carbon sink, have become a source of emissions, raising concerns over the country’s climate policy and carbon neutrality targets. According to the latest data from the Natural Resources Institute Finland (LUKE), Finland’s forests emitted 1.12 million tonnes of CO2 equivalent in 2023. This shift began gradually around 2010 and has accelerated since 2018. By 2021, Finland’s forests had transitioned from absorbing carbon to releasing it. The main causes are declining forest growth, increased logging, and rising emissions from forest soil. The land use, land-use change and forestry (LULUCF) sector, which includes forests, emitted a total of 11.8 million tonnes of CO2 equivalent in 2023. This makes it one of Finland’s largest emission sources, surpassing emissions from sectors such as agriculture. LUKE’s report highlights three key reasons behind the decline of Finland’s forest carbon sink.
