Research project:

Development of regional characterization factors for acidification on a global scale.

Project summary:

With the globalization of markets, assuming that the entire life cycle emissions of a product system occur within a specific geographical area (e.g. as Europe or Canada) is no longer a suitable assumption for regional impact categories, such as acidification, since the impact of a same elementary flow varies from an emission location to another. Although spatial variability within a continent, e.g. between countries in Europe, has already been evaluated as being significant, current LCIA approaches do not allow to consistently assess and compare emissions occurring from different continents as the characterization factors (CFs) provided by existing regional LCIA methodologies are obtained with different characterization models. Thus, a model covering a worldwide scale, but also able to account for local conditions needs to be developed to provide consistent regionalised CFs worldwide.
