EPS is a systematic approach to choose between design options in product and process development. Its basic idea is to make a list of environmental damage costs available to the designer in the same way as ordinary costs are available for materials, processes and parts. The designer may then calculate the total costs over the products life cycle and compare optional designs.
The EPS system, (Environmental Priority Strategies in product design) was developed to meet the requirements of an everyday product development process where the environmental concern is just one among several others. The development of the EPS system started in 1989 on request from Volvo and as a co-operation between IVL Swedish Environmental Research Institute, Volvo and the Swedish Federation of Industries (within the competence center Swedish Life Cycle Center (former CPM).
Since then it has been modified several times during projects, which have involved several companies, like in the Swedish Product Ecology Project and in the Nordic NEP project.
EPS includes an impact assessment (characterisation and weighting) method for emissions and use of natural resources, which can be applied in any Life Cycle Assessment (LCA).
The results of the EPS impact assessment method are damage costs for emissions and use of natural resources expressed as ELU (Environmental Load Units). One ELU represents an externality corresponding to one Euro environmental damage cost.
The latest previous version of the EPS impact assessment method was published in 2000. The present version was released 2015. The latest previous version of the EPS impact assessment method was published in 2000. The present version was released 2015 and has been developed within a project coordinated by Swedish Life Cycle Center (http://lifecyclecenter.se.
EPS 2015 are made in two versions:
The reason for developing two versions is the uncertain but important valuations of near-term climate forcers (NTCF) such as Nitrogen oxides (NOx) and Sulphur dioxide (SO2) emissions.
The 2000 version is replaced by the 2015 versions which can be downloaded below. For each version there is one excel file presenting the damage costs for emissions and use of natural resources and one excel file showing the calculations made for deriving damage costs via characterisation and weighting factors.
