New study on EV from Germany....wow it is getting confusing now

A German automotive consultancy Berylls Strategy Advisors:
"As we know electric cars do not release carbon emissions, but the problem lies in the production of their lithium-ion batteries. The energy required to make the cells results in a high carbon footprint. It is so high that the automotive experts have estimated that an electric vehicle in Germany would take more than 10 years to break even compared with an efficient combustion engine’s emissions.
Dr. Jan Burgard, managing partner at Berylls said in a statement, “Electric cars appear to be the panacea and reduce emissions by 35 %. After all, electric vehicles do not emit any carbon dioxide while driving – at least that is a widely held opinion. EV might not be as eco-friendly as the industries think it is. Unfortunately they do not improve the situation. After all, electricity generation – including for electric cars – is still strongly dependent on fossil fuels in many EU countries. The climate does not care whether carbon dioxide comes from the exhaust pipe or whether it is released when lignite is burned to generate electricity or in energy-intensive battery production.”
The study states that building a 500 kilograms EV car battery or bigger in a fossil fuel-powered factory will result in 74% more carbon emissions than producing a traditional vehicle. Burgard says that it is time to re-consider the diesel approach if the world wants to reach the environmental targets of 2030 EU CO2"
