On July 25, the European Commission implemented a law that informs automakers how to use “eco-innovations,” for cars sold in the European Union, in an effort to meet vehicle emissions reduction targets. Automakers can offset their carbon emissions target by as much as 0.4 ounces per mile if automakers fit new cars with an emissions-cutting device or technology that helps cut CO2 emissions and is not taken into account in determining the level of CO2 emissions from vehicles. Eco-innovations include devices that reduce vehicle electricity requirements and thus fuel consumption, enhanced energy storage systems, or devices that use solar or wind energy.
