Everything past 2030 is a kick the can approach and is not actually being pursued by anyone with any genuine effort. The people that made those pledges know they probably won’t still be working in 2035+. It’s not actually their problem, it’s the next guy’s problem. And if they don’t lay the groundwork or create steps for the next guy to meet their promised goals… Well, that’s also the next guy’s problem. They know they’ll be happily retired or in a different position by the time those promises are supposed to come to fruition. And if they’re not, they can just shrug and say something about a changing economy, or point out how no other country is meeting their goals (because again, almost no one is actually pursuing this in good faith), or, what’s more likely, just never bring up or acknowledge the goal again and hope everyone moves on/forgets.
