The Commission has opened a new laboratory to test fuel consumption and emissions from lorries and buses in more realistic conditions than are used in general 'type approval' tests.
The new facility, at the EU’s Joint Research Centre in Italy, will contribute to implementing the Euro VI emissions standards agreed last year, and will also help develop future emissions standards for heavy vehicles.
Environmental organisations have criticised existing vehicle tests for giving emissions readings that are much lower than the vehicles emit in real driving conditions.
