Although some effort has been done, if the full global warming effect is considered, also the parasitic methane emissions should be taken in account and not only CO2 for electric vehicles. Not just -20% (2020), but big changes are needed to counter the global warming problem. Drastic solutions are ultralight electric vehicles instead of the actual heavy ones. If the technology is well developed, it can reduce CO2 emissions by a factor 5 compared to usual electric vehicles (2050 target). It has also effect on the indirect CH4 emissions in electricity, but also at tire dust, which might be even the biggest source of particulate matter PM10-PM2.5. A vehicle concept F2E for two electric is proposed, towards a very good compromise between energy, comfort, cost, global warming and pollution
