In order to to clarify and calm the controversy, the Italian research institute RSE - Research on the Energy System has published a document that summarizes the results of various studies in this regard, conducted from 2015 to today. Among these we also find research promoted by the manufacturers themselves, such as Rimac and Volvo - not surprisingly two of the brands most committed to the electricity sector -, but also by public bodies.
The RSE document opens with a necessary premise: electric vehicles are not the solution to all evils, as they are still polluting in the production phase - more than a vehicle with a thermal engine, in terms of CO2 created during production - but they significantly reduce emissions during the use phase . Data in hand, there should no longer be any doubts about the environmental goodness of electric vehicles, but those who are against it struggle to face reality.

Taking into consideration several studies, and harmonizing the data collected where they were not exactly consistent, RSE came to the conclusion that to make a correct analysis between the life cycle of a thermal car and that of a electric car, many factors must be taken into account, including CO2 emissions during production and use, battery life (which is often underestimated precisely in order to make a critique), the different energy sources that can be used for produce and recharge the car, and the estimate of energy consumption to be done using real data and not those of the homologation cycles.
