Helsinki takes seriously its responsibility in fighting the climate change. Our goal is a carbon-neutral Helsinki by the year 2035. More than half of the carbon dioxide emissions in Helsinki currently originates from heating our city. More than half of our heat is now produced with coal. That's why we are preparing Helsinki Energy Challenge, by which we seek innovations, technologies and impactful solutions for sustainable heating. And we are in a rush – the Finnish government has decided to ban coal use in energy production from 2029 onwards.

One million euro Helsinki Energy Challenge in search for sustainable, long-term solutions for our future heat production. Join us in solving our Challenge: How can coal be replaced in the heating of Helsinki with as much carbon-neutrality as possible and as little biomass as possible?


"Climate change is the most crucial challenge of our time and Helsinki is one of the leading cities championing the fight against it. Helsinki Energy Challenge aims to find solutions for Helsinki but also more broadly for other cities around the world. Our partners will play a key role in achieving this goal. The C40 network collaborates with the Challenge already at the development phase. World Economic Forum’s Global Future Council is one of our partners in ensuring our success and the global relevance of the Challenge."

– Jan Vapaavuori, Mayor of Helsinki
