The EU is leading the way on stringent laws requiring automakers to reduce carbon dioxide emissions on vehicles sold in the member countries. An 18% average CO2 reduction will be required by 2015 and vehicles must have an average emissions level less than 130 grams per kilometer.

“Under the phase-in, 65 percent of Europe’s new-car fleet must meet the target in 2012; 75 percent in 2013, 80 percent in 2014 and 100 percent beginning in 2015.

To meet the 130g/km average, the EU will give carmakers individual targets based on the weight of their cars. The targets range from 122g/km for Fiat and 137g/km for BMW and Daimler.” (Source: Automotive News)

Here in the United States, California has the strictest emissions requirements but with a new administration stepping in and a set of policy makers known as the Green Dream Team, it is likely that the United States will adapt more strict emissions limits as well.
