Finnish companies and municipalities invested more than €2.1 billion between 2017 and 2025 under voluntary energy efficiency agreements, cutting annual energy use by 18.6 terawatt-hours compared with baseline levels, the government said.

The scheme, agreed between the state and industry sectors, allowed Finland to meet the EU’s strict energy efficiency obligations without new national legislation, said Sari Multala, Finland’s minister of the environment and climate. Some 780 companies and 160 municipalities and joint municipal authorities signed on to the 2017–2025 agreement period, together accounting for nearly 60% of the country’s total energy consumption.

Participants carried out a combined 34,500 energy efficiency measures over the period, supported by around €170 million in state energy subsidies. The government said the measures had cut Finland’s annual carbon dioxide emissions by up to four million tonnes.

A new agreement period covering 2026 to 2035 has already begun, according to the Ministry of Economic Affairs and Employment, the Ministry of the Environment, the Energy Authority and Motiva, which jointly issued the results.
