How to decarbonise the heating system in Helsinki with as little biomass as possible? One million euro Helsinki Energy Challenge in search for truly sustainable heating solutions for the City of Helsinki – and other cities around the world!

"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
