Yes! Energy renovations are the most effective climate action that a housing company can take. The energy consumption of buildings is the single largest source of carbon dioxide emissions in Helsinki, and improving the energy efficiency of old residential buildings is vital if Finland is to achieve its goals in mitigating climate changes. The energy consumption of dwellings and other buildings accounts for over half of Helsinki’s total carbon dioxide emissions. This is why the City is also encouraging private property owners to improve their energy efficiency.
