DHC: cost-effective carbon reduction and more jobs.

District Heating and Cooling (DHC) has proven to be a major contributor to Greenhouse Gas (GHG) reduction in many member countries and recognition of DHC's importance is growing. In fact, many countries where it is established are renewing their commitment to DHC as they find new ways to use the technology to reduce environmental impacts. DHC facilitates linkages between supplies that are environmentally desirable and end users that could not otherwise make use of those energy sources.

District Heating not only offers excellent opportunities for reducing environmental pollution, but also for achieving the goal of saving energy. It is an extremely flexible technology which can make use of any fuel including the utilisation of waste energy, renewables and, most significantly, the application of combined heat and power (CHP).

It is by means of these integrated solutions that very substantial progress towards environmental targets, such as those emerging from Kyoto can be made.

With regard to District Heating and Cooling there are myths and misconceptions that cloud the real fact that, where based on waste heat utilisation these systems are more efficient than the direct use of natural gas. It is an extremely flexible technology involving the increased use of indigenous or abundant fuels, the utilisation of waste energy and, last but not least, combined heat and power production.

District Heating and Cooling consist of pipe networks that enable other technologies such as combined heat and power to realise its potential by recycling or reusing waste heat. Energy efficiency results not only in a saving of fuels, but also in a consequent reduction of environmental pollution.

This policy paper clears up misconceptions that surround District Heating and Cooling and explains why DHC must be considered as part of the solution to a cleaner and sustainable future.
