The climate change and the indirect health effects have taken to a growing attention in reducing the greenhouse gas emissions (GHG). Road transportation has the highest footprint (70% vs. other transports), hence the European Union (EU) has reinforced the regulatory framework, establishing the rule out of internal combustion engines architectures (ICE) by 2035. To gradually approach the transition, the law provides for an intermediate step in 2030 setting -55% of GHG compared with 1990. All this translates in a widespread interest for greener technologies as full-electric vehicles (BEVs), leading historical Carmakers to innovate their fleet. In most Countries the energy generation is not close to be carbon neutral, because it is still derived by coal or other fossil fuels.
