The City of Helsinki’s Urban Environment Division has implemented a carbon limit of 16 kg/m2 over a 50-year period for all residential apartment buildings, with exceptions for diverse geometry and parking facilities.
This initiative aims to achieve carbon neutrality in Helsinki by 2035 and reduce the environmental impact of new building projects. The limit considers both operational carbon (emissions from building energy use) and embodied carbon (emissions from construction materials).
The calculation follows the Environmental Ministry’s low-carbon assessment method, emphasizing a lifecycle approach. Architects and engineers can contribute to meeting the limit by using low-carbon materials, designing energy-efficient buildings, and incorporating renewable energy sources.
