What are the stats on the carbon cost of making a new EV vs driving your current vehicle into the ground before making a new purchase. From my uneducated perspective, it's still more environmentally friendly to just keep driving your current rig until it dies vs the massive environmental cost of making any new vehicle.
Fair comment, especially if the existing vehicle is paid off. Everyone has their own set of circumstances and usage pattern.
Building an EV produces roughly 1.5 - 1.8 times more CO2 than equivalent size ICE vehicle. Ranges due to varying sizes, energy sources, supply chains:
5-7 tons for ICE
8-10 tons for EV
In-use emissions are zero at the vehicle itself for the EV - including non GHG nasties like NO2, CO and particulate carbon (soot). In BC and the PNW, our power grid is almost 100% hydro, so the lifetime emissions are far lower for EV, the CO2 emitted during its life is minimal, regardless of km driven or size of vehicle.
CO2 for ICE, we all know that varies with km driven, size, driving habits, etc. A half ton pickup with a small block V8 driven 20,000 km annually is going to generate 7 tons a year of CO2.
End of life recycling creates CO2 as well. About 2 tons for ICE, 3 tons for EV.
Taking the high side numbers (assuming trucks). ICE half ton:
Build: 7 tons
Use: 105 tons (15 years @ 7/year)
End of life: 2 tons
Total: 114 tons CO2 emitted
EV pickup:
Build: 10 tons
Use: 2.4 tons (.16 tons/yr, share of hydro carbon footprint)
End of life: 3 tons
Lifetime: 15.4 tons CO2 emitted.
For us in the PNW, it's no contest, even for a truck driven only 10,000 km a year. The cost savings are huge, will easily pay off the purchase price difference.
Most of Canada's power grid is supplied by non FF sources, primarily hydro and nuclear - almost 80% non FF. The argument that power grid is carbon fired doesn't apply very much for us.
Everyone's situation is different, but in general, the biggest and
quickest change most of us could make in reducing daily carbon output would be to switch to EV. The other major area for individuals is our homes. That takes more effort, time and money. But if you're looking for a vehicle anyway, consider your driving habits and if EV would fit the majority of situations. I know I still have to work out how to charge when on the road, but highway trips are only 10% or so of my annual driving.
