LCCP vs. eco-efficiency.

Author(s) : RIVA M., FLOHR F., MEURER C.

Summary

The contribution of anthropogenic greenhouse gases to global warming has become one of today's most urgent environmental issues. International treaties endeavor to achieve a reduction of the most relevant greenhouse gases. Concerning refrigeration technology, CO2 from energy production and direct emissions of f-gases used as refrigerants (HCFCs and HFCs) can contribute to global warming. These indirect and direct emissions are interdependent. Different assessment approaches are used to identify the most effective solutions for refrigeration systems and refrigerants with respect to a reduced environmental impact. Simplistic models consider only the global warming potential of the used refrigerant together with releases during operation of the system. The TEWI concept (Total Equivalent Warming Impact) extends the scope of the assessment to the CO2 arising from energy supply required during operation of the system. The LCCP (Life Cycle Climate Performance) evaluates the complete environmental impacts from cradle to grave, from manufacture of the refrigeration system, to the use of the system and finally to the end-of-life management. All these assessment approaches aim to describe the environmental impact of refrigeration systems. However, a conclusion about the optimally achievable result in terms of environmental impact cannot be derived unless the economic aspect of limited financial resources is taken into consideration. Therefore, the concept of eco-efficiency complements the LCCP with this crucial aspect. Using the example of a supermarket refrigeration system the authors show how the input data for the different environmental assessment methods are obtained. The notably different results of the different tools are discussed. The outlook considers other areas of refrigeration, e.g. MACs and stationary A/C systems, where the concept of eco-efficiency can also provide valuable insights.
