Trump promise to repeal Biden climate policies could cost US billions, report finds

Trump, however, has called this spending wasteful and vowed to erase it.

The reasoning of Trump for this:
I'm 78 years old, spending money on the safety of climate and the earth in the future, will not benefit me, a sociopathic malignant narcissist, in any way.

USA is polluting 4 times the global average per capita, meaning about 5% of the global population is producing about 20% of the world pollution.
If USA decide to do nothing, it's a huge setback for the world, and very irresponsible.
