Based on the mix of generating sources going into the grid , in some locations a bigger reduction in carbon emissions could be achieved by switching to vehicles with a lightweight internal combustion engine ( ICE ) instead of EVs , according to a study by MIT and the Ford energy agency . The principal research scientist Randolph Kirchain said he does not want to undermine EVs as a viable and short - term option for most of the US , but argues the need to understand the most effective measures for reducing emissions , so policies and incentives are put in place to “ produce the best outcomes ” .
Based on the mix of generating sources going into the grid, in some locations a bigger reduction in carbon emissions could be achieved by switching to vehicles with a lightweight internal combustion engine (ICE) instead of EVs, according to a study by MIT and the Ford Motor Company. MIT principal research scientist Randolph Kirchain said he does not want to undermine EVs as a long- and short-term solution for most of the US, but argues the need to understand the most effective measures for reducing emissions, so policies and incentives are put in place to “produce the best outcomes”.
