Climate change is sadly, totally irrelevant. There are so many other types of pollution that are completely ignored due to the emphasis on CO2. In China there are factory cities with giant lakes of sludge. They expense is to make our semi-conductors, flash memory and other electrical components. There is a tremendous amount of waste from the batteries (although Li-Ion batteries are cleaner to produce than the previous generations; and Musk is building a plant in the US at least).
The true problem is consumerism and planned obsolescence. Phones should last 10 years. They should have standard components like a PC. There should be one kernel that runs on all of them, like a PC. Old laptops should be re-purposed. We need to actually be able to recycle a Pentium 3 instead of shipping all our e-waste to Africa and China where kids pick through them for inefficient amounts of metals.
We need to stop consuming as much stuff. We need to pay higher prices for components that last longer, have a more complete recycling cycle and companies should actually be praised for not meeting sales targets if it means their old stock is simply lasting longer and no longer needs replacement. You shouldn't buy a new laptop if the old one is "two years old and running slow."
I'm not saying CO2 isn't a problem, but the sole focus on it is saddening because it's not the problem itself. It's a symptom of an extremely consumerist society. You cannot replace every gas vehicle with an electric one over the next 20 years. We simply don't have the resources. There are 4 barrels of oil that go into ever set of tiers, not to mention all the plastic and trim. We are getting more wind turbines and solar to better power those cars, yes .. cars that will simply never be built.
We need to reduce cars, have better train systems in every city, live smaller, consume less and make things last. No amount of CO2 emission reduction will solve the actual problem of increasing mass consumption, not until our population starts to curb.
Unfortunately, I don't think we'll see any real changed in the developed world until the next bubble bursts or the next major collapse.
