Yep, even including all of that they are cleaner.This is including the manufacture of the batteries, with the mining and all that? The articles I've found all boil down to theory; 'one day'/'working toward' using more eco-friendly materials to build the batteries with. One article I recently read even talked about how they've found some of these materials on the ocean floor and will begin digging that up. That hardly sounds like a step in the right direction, so I'm very interested in some reliable information to counter that. That's what I'm concerned about, because I don't question that ultimately - at the consumer level - EVs will be greener.
One of the main misdirections the anti-EV lobby use is to put an 'apples and oranges' comparison together and happily include the impact of production being higher in EVs, but forget to include the impact of fuel production and distribution when looking at ICE vehicles. Petrol and Diesel don't magically appear at a service station (as the models they use assume), and the oil deposit to service station impact of Petrol and Diesel production has a massive impact.
In regard to your point about it being better to keep running old cars over new ones, unfortunately, that doesn't stack up, as the longer a car is driven the more fuel use becomes the major factor in terms of environmental impact, and its double hit, as older cars are less efficient and ecologically sound than more modern ones to start with and get worse as the age (because the older they are the less likely they are to be well maintained). While the numbers will vary, one study puts the split (in terms of lifetime emissions) at 75% from driving it, 19% from the production and transportation of the fuel it uses and 6% from its manufacture. Now that report was written back in 2000, a more recent one (from 2014) shows a quite different split, with one VW model having 68% from use, 9% from the supply of fuel (because it's using less), 1% from the recycling of the car at the end of its life and 22% from manufacture.
Now while at first glance that looks worse (22% vs 6%) this once again is not a direct comparison, because the overall CO2 for the latter vehicle is far lower, these factors still make the more modern vehicle more ecologically sound than the earlier one, despite production being a higher percentage. EVs can take this concept even further, lowering the whole life CO2 impact to a half or lower of the 2014 model, and even more below the 2000 model. The end result is that from an environmental point of view, yes getting a new or used EV and driving it into the ground is going to be better than taking any older car and doing the same.
