Residents in Lauttasaari and Maunula can compare emissions from housing companies
In Helsinki, the Lauttasaari district association investigated the carbon dioxide emissions of residential buildings in the Lauttasaari and Maunula districts. The populations of these urban districts are comparable to those of small municipalities.
Data on energy consumption and energy renovations of housing companies were collected from the boards of housing companies, as well as through property management offices, open databases, and the databases of Helsinki City Housing Ltd. Based on the actual heating, electricity, and water consumption, estimates of carbon dioxide emissions were calculated for each housing company that provided data. Residents can view and compare the emissions of housing companies on a map. Events have been organised for residents, and information has been shared about ways to improve energy efficiency in their housing companies.
Results expected from the subproject
During the project, 12.4% of residential buildings in Lauttasaari and Maunula reported their energy consumption data. Based on this data, accurate carbon emissions were calculated for 2021, 2022, and 2023. From 2021 to 2023, the carbon emissions of Lauttasaari’s residential buildings decreased by 664,155 kgCO2e (-18.3%) and those of Maunula by 363,480 kgCO2e (-6.6%), amounting to a total reduction of 1,027 tCO2e. The largest reductions were recorded in housing companies that transitioned from district heating to geothermal heating during the project.
Private transport emissions were calculated for Lauttasaari and Maunula for 2022. Passenger cars in Lauttasaari produced 14.6 ktCO2e and in Maunula 4.5 ktCO2e. Emissions from vans were 0.9 ktCO2e in Lauttasaari and 0.2 ktCO2e in Maunula. Due to time constraints, private transport emissions for 2023 could not be calculated, leaving emission changes during the project unquantified.
Given the short duration of the project (April 2023–May 2024), it is not yet possible to reliably assess the impact of its measures on the carbon emissions of buildings and traffic.
