where we work / Europe


With more than 15 million cars and trucks sold annually, the 28-member European Union is the world's most important vehicle market. Every fourth vehicle sold worldwide is produced in or imported into Europe, and its influence on the business decisions of major global vehicle manufacturers is significant.

Traditionally, the EU has set the pace for the reduction of greenhouse gases from transport and conventional pollutants. Europe is home to a large number of innovative vehicle manufacturers and suppliers, providing advanced technologies that help reduce emissions from transportation.

Italy’s car market needs to make a U-turn

Like magic! How to make high vehicle CO2 emissions simply disappear
On June 26, the BMVI finally published the CO2 measurement results we had been waiting for. But in the interim the Ministry re-tested 29 of the original vehicle models. Only a subset of those results, data on 19 out of the 29, was published and in many cases, the vehicles show lower CO2 emissions during the retest than according to their official type-approval value. Those are impressively good results—and strikingly different than the initial results from 2016.
