As part of the Hotmaps project which developed a database and toolbox for strategic heating and cooling planning, the city of Frankfurt has set the targets of reducing by 50% CO2 emission by 2030 and become carbon-neutral by 2050. At the beginning of the project Frankfurt´s heating system was approximately fuelled at 70% by fossil gas.

One of the first results concerns the quantitative scenario analysis which showed that 60-80% of the buildings’ heat demand in the city should be covered by district heating, especially to use the large amount of excess heat.
