I think some kinds of global carbon tax + other green house gasses (GHG) done at a WTO type level.

Stop telling people what they can/cant do this and focus on pricing the damage points. Puts costs against goods like meat production, petrol cars, private jets etc. Rather than moralise, put a price on them and give people the choice. This will encourage farms to use seaweed to reduce cattle methane or bring in electric planes or goods that last longer.

Ideally this could be taxed at a national level. And for countries that wont, put export/import tariffs on them from the trading block to meet the cost they should have taxed. Monies raised must go towards environmental improvement measures e.g. buying land for forest regrowth or carbon scrubbing.

Obviously huge global plan with masses of detail and nothing is perfect, but generally I feel putting agreed globally consistent costs on GHG emission seems the best way to redirect the world to better behaviours.

So affluent people can go on as usual and low income families are priced out of travel and heating.

It's not that simple.

I feel its simple to say "It's not that simple" whilst not trying to show an alternative.

Any solution is going to have downsides. For right or wrong, it doesn't seem realistic to make some solution where a wealthy upper echelons take all or even the majority of the weigh of a global problem.

Most of the world is low income, and you need to bring in the mass market for change. And there will be issues for sure but if you dont force change across the entire market little will change. Like do you expect we make a rule where people below $20k income to keep using petrol cars without any new cost but everyone else goes electric? Bad example? Maybe some proportional carbon/GHG tax system? Doing that at an individual level would be very difficult.

Id love to be wrong but I dont see a solution where we make global changes of any real significance and dont effect low income people, which is much of the world. Do you?
