Topic of the practice

Presentation of experiences from the first eco-labelled district heating and district cooling in Sweden

Good Practice Information

Norrenergi, which is an energy company owned by the cities of Solna and Sundbyberg, and the Swedish Society of Nature Conservation (SSNC), was the first energy company in Sweden offering its customers district heating and district cooling awarded with SSNC's Good Envrionmental Choice eco-label. Norrenergi produces about 1 TWH district heating every year. More than 50% of the heat production comes from large heat pumps which use residual waste water as heat source. Heat is also produced in hot water boilers, which are fuelled with wood briquettes, pellets and tall oil pitch. Bio fuels account for 27%, tall pitch oil for 13% and fossil oil for 2%. Noorenergi also produces about 70 GWh district cooling every year. District cooling is generated by heat pumps, cooling machines and cold sea water. There are strict environmental requirements on district heating/cooling certified in accordance with "Good Environmental Choice".
For example, no more than 10% of the supplied heat or cooling may orginate from non-renewable energy sources; the plants' efficiency must be at least 70% and the plant must have a control system to trace the origins of the biofuels; the suppliers of wood fuel must fulfil the demands for certification according to the Forest Stewardship Council or practicing equivilent principals aiming at sustainable forestry practices. Wood fuel may not come from illegal logging or forests with high conservation values. Palm oil may not be used as biofuel; heat or cooling from heat pumps must come from geothermal sources, lakes, solar energy or process water from food industry. Electricity used for heat pumps must come from renewable sources.

Evidence of success

This best practice shows that eco-labelling of heat production can result in improved routines in energy companies of requirements on contractors and higher motivation within the company to work with reducing the negative impacts of its activities. It also shows that eco-labelling is a possibility for energy companies to improve their credibility towards their customers.
