Most pollutants actually come from brake pads, so lack of ice will only knock total emissions down 30ish precent. But everyone likes to think its only the engine. Also consider the impact of mining copper and lithium. Its still in favor of conventional cars by a wide, but closing, margin.
- alex_duf 10y ago> Most pollutants actually come from brake pads It's the first time I'm hearing about that, the good news is that with electric cars and regenerative breaking you barely use the mechanical break. Also, I wouldn't qualify it as being "Most". Most of the particles yes, but not most of the green-house gas, which could reach a theoretical 0 if the production of energy is managed correctly. I guess it all depends on everyone's definition of "pollution" I found this paper about brake pads and their impact on micro particles: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4315878/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4315878/

If driven properly, the brake pads on an electric car will almost never get used, eliminating the majority of those emissions too.
