Ultralow carbon vehicles and supercredits

Also available in the following languages:

In 2009, the EU set legally-binding targets for new cars to emit 130 grams of carbon dioxide (CO2) per kilometer (g/km) by 2015 and 95g/km in 2020.1 The Commission recently proposed a review of the way the 2020 target should be met.2 This confirmed the 95g/km value but reintroduced supercredits (additional rewards for sales of ultralow carbon vehicles) that weaken the target.

This paper outlines why and how the market for ultralow carbon cars should be supported without reducing the wider benefits of improving the efficiency of conventional cars.
