General non-discriminatory carbon tax. Investing heavily in nuclear. Just 2 obvious ideas that noone is even trying.

Most of climate change is caused by fossil fuels. The rest are caused e.g. by factory farming (plant & animal - e.g. pesticide rundown), plastic pollution, etc.
If we had boundless nuclear energy, not only would fossil fuels become price inefficient, we could devote the extra energy we generate into synthetic fossil fuels, carbon capture, reducing pollution, etc. Almost all of these are energy bound right now.
