Electric Cars Emit 50 Percent Less Greenhouse Gas Than Diesel, Study Finds

entirely_fluffy shares a report from The Guardian: Electric cars emit significantly less greenhouse gases over their lifetimes than diesel engines even when they are powered by the most carbon intensive energy, a new report has found. In Poland, which uses high volumes of coal, electric vehicles produced a quarter less emissions than diesels when put through a full lifecycle modeling study by Belgium's VUB University. CO2 reductions on Europe's cleanest grid in Sweden were a remarkable 85%, falling to around one half for countries such as the UK. The new study uses an EU estimate of Poland's emissions -- at 650gCO2/kWh -- which is significantly lower than calculations by the European commission's Joint Research Centre science wing last year. The VUB study says that while the supply of critical metals -- lithium, cobalt, nickel and graphite -- and rare earths would have to be closely monitored and diversified, it should not constrain the clean transport transition. As battery technology improves and more renewables enter the electricity grid, emissions from battery production itself could be cut by 65%, the study found.
