T&E: tests show cars powered by electrofuels emit high levels of criteria pollutants

Green Car Congress

Proponents claim that if renewable electricity is used and CO 2 is captured from the air, then the e-gasoline and e-diesel are climate-neutral fuels that will also reduce pollution. A 10% blend was chosen due to existing fleet and EN228 standard compatibility. The emissions were compared to the standard E10 EU gasoline.
