Lauttasaari-Seura ry: Towards carbon-neutral city districts

Avoin ry:n karttakäyttöliittymä

The aim of the Lauttasaari-Seura subproject is to look into and decrease the emissions from buildings and private transport in two Helsinki districts, Lauttasari and Maunula. In addition, the project develops methods for reaching the area’s residents and encouraging other districts to join the climate work.

Buildings’ energy consumption and energy renovation data made visible with a map interface

During the project, the realised carbon emissions from buildings in Lauttasaari and Maunula are surveyed. The data on the housing companies’ energy consumption and energy renovations is collected directly from the boards of housing companies, as well as building management agencies, open databases and the databases of the Helsinki City Housing Company (Heka).

Based on the collected data, the realised carbon emissions of a housing company can be calculated using an application that will be developed. Avoin ry, a partner of the subproject, manages a map interface through which it is possible to inspect the carbon emissions of housing companies and other data relating to energy efficiency. The map interface can be found at:

The project group provides information to residents on improving the energy efficiency of the housing company. Through the map interface, residents can independently inspect and compare the energy consumption and energy renovation data of their own housing company with other housing companies.

Towards low-emission traffic

During the project, the emissions of the private transport of Lauttasaari and Maunula residents are being surveyed in cooperation with Traficom. The aim is to increase residents’ awareness of the significance of their own choices and encourage them to choose low-emission forms of transport in their daily lives.

The project group informs and influences residents’ transport habits primarily through communications and events. With the subproject’s actions, the emissions of Lauttasaari’s and Maunula’s private transport is expected to fall by 10 per cent.

Residents as active environmental influencers

The Hiilineutraalit kaupunginosat (Carbon Neutral City Districts) subproject was born thanks to the activity of residents. Lauttasaari-Seura’s Carbon Neutral Lauttasaari 2030 project group has worked on a volunteer basis since 2020 to promote and spread awareness of climate and environment issues. Active work for climate issues has also been carried out in the Maunula district of Helsinki over the last few years. Lauttasaari-Seura and Maunula-Seura see residents as active influencers who are interested in the development of their own home area and environment.

During the project, residents are regularly informed of its progress and results. The project group publishes data in, among others, the Lauttasaari and the Maunulan Sanomat newspapers, the project’s home page and in social media channels. In addition, results will be presented in Lauttasaari-Seura’s upcoming climate seminars and other possible events. The project group delivers data on the project’s progress to Helka ry, through which climate activity will, hopefully, expand to Helsinki’s other districts.

Results expected from the subproject

  1. At least 10 per cent of buildings in Lauttasaari and Maunula report their energy consumption data to the project while it is ongoing.
  2. The emissions of private transport decrease by 10 per cent during the project in Lauttasaari and Maunula.
  3. With the project’s actions, carbon dioxide emissions decrease by a total of 1,000 tCO₂e during the project and two years after its end.
