The greenercars environmentalist website ranks all cars cleanliness (from factory to disposal). They list the Prius ICE-based car every bit as efficient/clean as an EV.
They also rank the new diesels (designed to run on sulfur-free fuel) as being only a few percent less clean than the Prius & other hybrids:
55 Prius, Civic hybrid
51 Fusion hybrid
47 Jetta TDI, Audi A3, Gulf TDI
46 Beetle TDI, Passat TDI
Out of 100 max score. The cleanest cars ever made (according to greenercars) were the ICE-based Civic CNG, and the 70 mpg Insight hybrid (both ranked 4% cleaner than the Prius or an EV)
