Comment on Canada to announce all new cars must be zero emissions by 2035
Fisk400@feddit.nu 9 months agoAre you saying that the emission resulting from an EVs production is the same as the emission from and olds car production and lifetime of fuel usage combined?

Production of batteries, handling discarded batteries, breaking of minerals FOR the batteries, and producing the electricity have all been shown to be worse for the environment than than the entire life of a traditional car

You got something to back that up? The last study I read (I think it was from Volvo comparing one of their EVs against the ICE version of the car) showed between 60 and 80 thousand miles (depending on the energy generation mix) was the tipping point where EVs became better.
And that was probably about 5 years ago, there’s been a lot of significant development in EVs since then.

Well, please show me a trustworthy study of the difference between ICE and EV emissions per mile during their lifetime. The ones I’ve read always say “in their lifetime”, but they don’t take into account EV batteries need changing after about 10 years … And batteries are as we know the “big bad” of EVs. The absolutely only true comparison would be all emissions from all sources spread out over either per mile or per year. A combustion car can easily last 20 years, which isn’t really a fair comparison to the 10 years.

Hey you made the claim in the first place, you have the burden proof. Don’t attempt to shift it.

Na mate, I asked first.

Conventional ICE can last 30 years, with engine and trans rebuild, which is trivial from a materials standpoint.
We have multiple 30 year old ICE vehicles that still get 30mpg, have air conditioning and unlimited heat.
EV will never compete with that unless we find new ways to make batteries.

No calculation I hage ever read has ever shown that. There is an initial increase of emission from the new cars production, which is why there are discussion about retrofitting existing cars, but even if we never improve our battery technology there is a dramatic gain in lowered emissions.
