Introduction of excess heat in a district heating system can provide an opportunity for reduction of carbondioxide emissions. Combined heat and power plants produce both heat and electricity and introduction of heat-drivenabsorption cooling in an integrated district heating and cooling system can increase the potential for electricityproduction which in its turn may reduce carbon dioxide emissions when replacing other, more carbon intensive,electricity production. Depending on what assumptions are made for marginal electricity production the carbon dioxideemissions of the system will vary. In this paper the introduction of industrial excess heat and absorption cooling isanalyzed for an integrated district heating and cooling system using three different types of fuel and two sources ofelectricity production. The results show that introduction of excess heat will reduce the use of resources but dependingon what other electricity production will be replaced in the surrounding system, the carbon dioxide emissions are notnecessarily reduced. Absorption cooling increases the heat demand and thus increases the use of resources but can stillreduce the carbon dioxide emissions if the increased production of electricity is assumed to replace electricity from coalcondensing power plants. If the increased electricity production replaces electricity from average Nordic electricityproduction, introduction of absorption cooling will increase the carbon dioxide emissions.
