:::That claim is truth only for direct tailpipe or onboard emissions. The PHEV article here presents a summary for PHEVs in the US. The W2W emissions depend on the regional power generation grids, some regions are truly cleaner, and several are worst than ICEs, and for most, conventional electric-hybrids are cleaner. See also this study here. Nevertheless, no such a claim is made in the article, and I already delete the content mentioned above and included the wiki links to the above mentioned section and other wiki articles. Or am I missing something? -
