The cost of creating new computers has got to be pretty high to the environment (I've heard 85% of lifetime carbon emissions from computers are from the manufacturing process), and I strongly suspect that we don't take that into consideration since we greenwash ourselves by forcing China to do our dirty work, chastising them for it, and then patting ourselves on the back for buying "more energy efficient chips".
We need an index of lifecycle costs for products and services, broken down by phase (material production, manufacturing, logistics, operations, disposal, etc.). It's especially needed because those costs are often externalized for buyers (i.e., they aren't built into the price - you don't pay the true cost of gas, for example; many costs are externalized to everyone else). How else can consumers, manufacturers, policymakers, etc. make anything like an informed decision?
I'm surprised someone like the Sierra Club, Consumer Reports, a scientific group, a government group, etc. doesn't undertake it. Yes, it's a bunch of work, there would be uncertainty, but it's essential and better than nothing.
This is why people keep bringing up a carbon tax. It does a lot of the work to internalize all those externalities so individuals or groups don't have to try and figure all this stuff out.
Yes, unfortunately even the best intentioned individuals have very limited ability to make meaningful carbon-minimizing decisions. Carbon tax is such a sensible solution!
They aren't; among other things, most environmental harm is externalized. When you buy things that produce climate change or microplastics, the cost of the impact is paid by society generally.

But aren't those made regardless if the people with old computers upgrade to them or not? I guess over time, they'll make less if people buy less, but the ones we'd purchase today has already been made, and might as well replace less energy efficient devices than just being added to the global count.
