The UCS has been regularly publishing data on whether grid charged EVs or ICE had lower CO2 in the USA. Even their oldest data in 2012 shows a clear improvement, based on the assumption of grids not getting cleaner with non-hybrids being worse everywhere in the US, and hybrids only competitive with EVs in the worst grid areas:
Their updates obviously showed continual progress from there as the grid cleaned up, a process which continues, as does lower carbon footprint batteries (LFP is half the carbon of NCM) and higher efficiency EVs.
It would be interesting for them to revisit the old projections with the 12 years of newer grid data and calculate the real numbers and compare them with their conservative estimates.
