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.

The basic 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.

SPINE@CPM – the operational prototype for industrial LCA databases

Raul Carlson, project manager and developer of the database:

The 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.
