Reduced carbon footprints of buildings: new Finnish standards and assessments

The Nordic countries are working towards regional carbon neutrality ahead of the European Union’s goals. Finland is aiming at carbon neutrality by 2035, and developing a set of policies, including legislation for low-carbon construction. The new approach includes normative carbon limits for different building types before 2025. Finland’s Ministry of the Environment has developed an assessment method and will develop a generic emission database. The database will cover all main types of products and materials, sources of energy, modes of transportation as well as other main processes such as site operations and waste management. Furthermore, the criteria for green public procurement have been developed from the viewpoint of reducing the climate impacts of buildings: incorporating global warming potential and climate benefits. However, there are several open questions regarding both the assessment method and the database. These questions are outlined and discussed. The consideration of the foreseen decarbonisation of energy, the relation of the generic data to specific data and the requirements for generating valid generic data are key issues of discussion. The Finnish assessment method is also compared with the methodological development in other Nordic countries and to the proposed Level(s) framework of the European CommissionPeer reviewe
