Lomborg: ‘Global green transition cost is now $14+ trillion’ – ‘Over $2 trillion/year’ – But ‘Still, CO₂ emissions set another record last year’

Climate campaigners tell you green is cheap

It isn't

Global green transition cost is now $14+ trillion, rising with over $2 trillion/year (2% of global GDP)

105x our spending to avoid hunger

Some people suggest that while green is expensive, the benefits are much greater

Well, no:

The benefit of net-zero is $4.5 trillion/year, but the cost $27 trillion

(much larger costs and benefits, because we're currently only doing a bit of net-zero currently)… pic.twitter.com/2wT08AVc36
