United States EPA vs Volkswagen: defeat devices on diesel passenger cars






SEFIRA Project is following the developments of the breaking news about the accusation from the United States EPA to Volkswagen of cheating on real driving emissions on its diesel fleet. The controversial relationship between declared, tested and real drive emission (RDE) has already been described in the past years by several indipendent researches. This case has been opened thanks to the effort of the International Council on Clean Transportation. In our SEFIRA Policy Brief #2 we highlighted this problematic issue in connection with the Clean Air Package discussion and negotiation process, still ongoing in the EU Parliament. SEFIRA has stressed the importance of matching the technical devices for emission reduction with the adoption of non-technical measures to foster relevant behavioural and ecological changes to improve air quality.

Socio Economic implications For Individual Responses to Air Pollution policies in EU +27

SEFIRA has the objective of creating a European coordination of transdisciplinary scientific and socio-economic resources in order to support the review and implementation of air quality legislation by the European Commission (EC) led by DG Environment. SEFIRA will coordinate some of the best scientific and socio-economic resources and will review air quality policies and legislation at the interface between environmental, economic and social sciences in order to achieve a deeper understanding of these complex issues. The main fields involved in the action will be atmospheric sciences, environmental and legal sociology, anthropology, geography and economics.
