Unavoidable. They're playing catch up. It seems fairly obvious to me that we should say "Total emissions by some date (say 2080) should equal some value (say X) and we calculate from the Industrial Age to that date and apportion according to what percentage of the Earth you own". The West polluted from 1900 to 2020 and reaped the rewards. The cutbacks The West must make must be proportional. Otherwise it's like inheriting all your wealth from a thief and then making thievery a blanket crime.
