Canada expects to announce this week that all new cars will have to be zero emissions by 2035, a senior government source said, as Ottawa is set to unveil new regulations in the latest example of countries around the world pushing for electrification.

    Interested to see where that data comes from, as looking at the lifetime emissions of an EV vs an ICE vehicle inclusive of fuel EVs are generally significantly lower emissions. If you’re only considering the emissions associated with the manufacture of the vehicles, EVs do result in more GHG, but very quickly once both vehicles are actually in use the benefits of EVs become apparent.

      While somewhat misguided, they do still kinda have a point: Car centric culture really does have a high environmental cost regardless of power source. Switching from ICE to EV is a good start, but we also need to address urban sprawl, and push for better mass transit as well as cycling infrastructure.

      I’m working from memory, but I think I have heard their claim before, and the data it is based on is probably 20 years out of date. The proportion of electricity produced by methods like solar and wind did not used to be what it is today, and the production method of electricity plays a significant role in lifecycle analysis of electric vehicles.

      The Cambridge link you provided notes that electric vehicles are not better for the environment in Poland because most of their electricity is produced by burning coal. It also compares France and the UK, and notes the difference between emissions because of the different production mix of electricity.

      Under current conditions, driving an electric car is better for the climate than conventional petrol cars in 95% of the world, the study finds.

      The only exceptions are places like Poland, where electricity generation is still mostly based on coal.

      Average lifetime emissions from electric cars are up to 70% lower than petrol cars in countries like Sweden and France (which get most of their electricity from renewables and nuclear), and around 30% lower in the UK.

        I believe I saw similar comparing US states, but do not have a link. The numbers I remember is 1-2 years in states with more natural gas, nuclear, and renewable energy, up to 14 years for West Virginia and Wyoming as still mostly coal

          IIRC, if you pick the worst state for power sources (W. Virginia) and the worst EV (the Hummer), you end up with a pathological combination that emits more CO2 than any ICE over its lifetime. Literally any other combination, and it’s better.
