"Climate change is a global crisis that will not be solved through quick fixes. With the Helsinki Energy Challenge we are seeking new innovative solutions, even if it would mean significant changes to our existing system. We invite innovators from all around the world to use Helsinki as a testbed for truly sustainable solutions for urban heating. Taking this next step might lead to a revolutionary breakthrough in our fight for a more sustainable city life."
– Mayor of Helsinki, Mr. Jan Vapaavuori
