Electric and hybrid penetration by 2030 based on new CO2 targets
![]()
The EU has published the “Fit for 55” proposal which will require 55% reduction in tailpipe CO2 by the end of the decade. The Biden administration will also revise the SAFE standards and has announced a 50% electrification target by 2030 (including plug-in hybrids). Here is a look at the implications for powertrain scenarios based on the CO2 targets alone.
