I found you can calculate your emmisions for your petrol car using this formula:
- Premium petrol - L/100 km x 23.414 = CO2 grams/km
- Regular petrol - L/100 km x 22.847 = CO2 grams/km

So for a car getting 8L/100km emissions are 183g CO2/km.
What surprised me is that for half the countries listed, you are actually better off driving a gas car than electric. Canada would depend entirely where you live, becuase I think our graph number is greatly distorted for Alberta by the hydro resources east and west of us. I'm sure Alberta's number would be over 200.
Anyway, maybe I'm missing something big here becuase it doesn't seam to make much sense given our current energy mix to go electric. I thought it was guaranteed to have lower CO2 emmisions, but I guess it depends where you live. Am I missing something? |
Nope not missing anything. Areas of the world that primarily use coal fired boilers to feed steam turbines are going to pollute a considerably more than other methods. Coal is filthy all around as if you have ever worked or visited a coal fired plant you would find that the entire facility is contaminated by fine coal dust. Touch anything that looks clean and you will have black on your hands.
