| EPS - Navigating through facts and opinions
Bengt Steen, author of the impact assessment method EPS:
The EPS system (Environmental Priority Strategies in product design) was
developed as an aid in product development. The system is basically
a set of hierarchic principle requirements, such as working
with aggregated impact indices, with transparency as an
available option, operationality, estimation of uncertainty,
and a default database. The EPS default method is operative
and includes a default database. The default method has been
updated a few times. The present version is called EPS 2000d.
idea behind the EPS system is that it should be used in the
same way as cost calculations in the design process. If a
material or a process has high environmental costs it should
trigger the designer to look for something else or be careful
to allow for recycling of the material so that some of the
impact cost is paid back at the end of life for the product.
The unit of the weighted and aggregated impacts in the EPS
2000d method is ELU, Environmental Load Unit. One ELU is equal
to an environmental damage cost of one EUR, but we have chosen
to express the damage cost in another “currency” than EUR
because there are some specific exchange rules between the
damage costs and the real money, like no discounting of future
impacts and equal values for equal damage all over the globe.

operational prototype for industrial LCA
Raul Carlson, project manager and developer of the database:
SPINE@CPM LCA database was established to facilitate any
type of industrial LCA studies of products and business
activities. The LCI-part of the database holds
well-documented data that describes resource use and
emissions from different industrial production
processes, plants and supply-chains.
