Fortum and the City of Espoo have committed to carbon-neutral district heating in the district heating network operating in the Espoo, Kauniainen and Kirkkonummi regions in the 2020s. The development work has since been accelerated with a new intermediate goal to discontinue the use of coal in 2025. The accelerated project for carbon-neutrality in 2020's is called Espoo Clean Heat.
The new generation of district heating is based on replacing fossil fuels with smart and flexible solutions, e.g. by utilising waste heat, renewable electricity, geothermal energy, and bioenergy. Artificial intelligence optimises the district heating system’s operations.
