The good news is that the US, and to a lesser extent China and the EU have improved their policy since COP26. Bad news is the rest of the world on average went backwards. Good news though is that on net we still get about half of the overall effect, and that's going to be a reduction half a billion tons of CO2e per year in 2030. Bad news is that it still isn't enough to limit things to 2 °C. Good news is that if we really implement all our pledges we might make it.

Even better news is that it's evident that action by any one of those blocs (US, EU, China, India) is going to be substantial. Of course, if all of us worked together that would be even better, and just because they're like half the world's population doesn't mean the other half won't have any effect.
