Expressing targets in absolute terms is an improvement over the gameable ways of expressing things we have now
But 2050 is unreasonably far away. Civilization could have collapsed by then, or sooner. There is no safe speed to apply needed changes. Any timeline that is not "now, immediately, without delay" risks politicians saying it's deferable or not their job, or saying that whatever unmetered thing they do in the interim, no matter how feeble, is all that's required to set up future success.
Plus some other nations will not do their part. It matters for everyone to. But everyone must overachieve hugely to cover others' failures.
We need governments to just say "now, highest priority, all hands on deck, all other considerations secondary". Talk of far off dates, with paced action, is just so much spinning of fairy tales and will get us all killed.
