There is an electricity/gas crisis, a food crisis, a water crisis, crises of both methane and carbon dioxide emission, and many more. governments are doing a lot of beating around the bush, when they could solve them all quickly.

You tax the scarce thing at a high enough rate that consumption drops sharply. You use the tax income to subsidise the people who really need the thing.

Take methane for example. You calculate (roughly) how much methane is produced per kilo of beef, per litre of petrol, per tonne of fertiliser, per metre squared of concrete building. Then you add a tax on each product, fairly, according to how much methane it produces. But this causes prices of beef, grain, concrete buildings, and everything else to rise slightly. So you give back the tax as UBI, or doles increases, or VAT or income tax reductions.

So the affordability of food does not rise at all, yet there is a strong incentive to use less fertiliser, and to farm and buy meat which produces less methane.

There is nothing complicated about this. It can be done quickly.
