On another note, and I haven't verified the information yet, the claim is that electric cars consume a huge amount of Co2 in their production. The question then is simple I suppose, how much Co2 does each kind of vehicle make over its life cycle?
Thanks again

Ok, big and complicated questions. Rather than the simple "Just Stop Oil" message.
Right, oil alternatives. Castrol is named after a plant used for oil. Mineral oils generally perform better and are cheaper (it's still used to lube jet engines), but we could stop growing food and start growing oil instead. If you followed the Wiki link or followed up on the last few lines of my quote you would note that "palm oil" performed better than sperm whale oil for some uses. Of course there are or were environmental questions about palm oil plantations. I should know I use to hold shares in a palm oil producer.
CO2 from car production. Well, we could talk about how many cars use more Aluminum than steel. Aluminum needing electricity to process, which was traditionally produced using hydropower but is often done so using coal fired power plants in some countries. Steel does need CO2 emissions. But let's not go there. Instead let us ignore the biased claims and examine the facts. Logically it's not the amount to produce an EV, but the amount EXTRA if it does take extra. The thing that is different between a EV and IC car is the motor, batteries and steel gears.
So more copper and less gears (smelting copper and iron needs CO, and converts it to CO2). Though Aluminum is also a good conductor of electricity and heat. Lithium extraction is not CO2 intensive, but relatively environmentally damaging. Of course the claim was about CO2. I'd personally say that the argument is a bit moot and the Anti-EV lobby clutching at straws. However it is possible in my opinion that EV's do require extra CO2 emission if neither car were ever used.
Fueling one from wind turbines or nuclear power though might make a difference to total CO2 emissions. Especially if you include the refining process that produces petrol in the equation.
Ps artificial fertilizers are normally produced using natural gas. Although I will accept that oil and gas are the same industry and that you can't really extract one without the other. I doubt that "Just Stop Oil" realize the fact, or object to fertilizers produced using gas.
