Earlier this year, the U.S. Environmental Protection Agency announced it’s working on new rules to decrease NOx and other pollutants present in vehicle emissions. January’s announcement will not be the only major one relating to worldwide vehicle emissions, with China 6a set to come into force this year. Similarly in Europe, the EU’s next phase of emissions standards (Euro 6) comes into effect in 2021, under which the average CO2 emissions of new cars can be no more than 95g/km under real driving conditions. This limit will drop by a further 15% in 2025, and 37.5% in 2030.
