Lex Fridman Podcast · #339 – Climate Change Debate: Bjørn Lomborg and Andrew Revkin · 18 Nov 2022 podcast

So we used to be big.

But in the 21st century, we'll be a small bit player.

And so we're basically spending a lot of money.

And remember, a trillion dollars is a lot of money that could have been spent on a lot of things that could have made humanity better on something that will only make us a tiny bit better.

Now, it will do some good.

The reasonable estimates is if you do a cost-benefit analysis, and again, technically, it's really, really complicated, but the basic idea is very, very simple.

You just simply say, what are all the costs on one side and what are all the benefits?

The costs are mainly that we have to live with more expensive energy.

You have to

forego some opportunities.

You have to have more complicated services, that kind of thing.

The benefit is that you cut carbon emissions and that eventually means that you'll have less climate damage.

You'll have lower temperature rises and so on.

If you try to weigh up all of those, it's reasonable to assume

that the EU policies will deliver for every dollar you spend, it'll deliver less than a dollar, probably about 30 cents back on the dollar, which is a really bad way to spend dollars because there's lots of other things out in the world where you could do, you know, multiple, you know, so for instance, if you think about tuberculosis or education of small kids or nutrition for small kids and those kinds of things, every dollar you spend will do like 30 to $100 worth of good.

So there are much, much better places where you could spend this money.

Likewise, the US is thinking of going net zero by 2050.

It's not actually going to happen, but it's sort of a thing that everybody talks about.

Biden is talking a lot about it.

If you look at the models that indicate how much will that cost, it's not implausible that this will cost somewhere between $2 and $4 trillion per year by mid-century.
