I know the USA is boycotting for a different (and a very bad) reason, but I feel like (with hindsight) it would have been a smart move for other countries to abandon this conference and demand something better.
Demand from whom? If major players decide they don't give a shit, then this is the way it is.
And China does produce and installs tons of solar panels, windparks and batteries, but they also build as much coal plants as they can. African leaders all in all seems loud to use climate change as a means to get more developement funds/compensation and that's it. The arab world gets angry if the oil output gets reduced. Then there is south america, where from what I know of personal interactions, climate change is largley a unknown term, unless it is used to somehow attack the "west".
But yes, what to expect if the richtest country does not lead by example.
This is our climate we are talking about, failure to address climate change has dire consequences. I am simply asking our leaders to act accordingly, nothing less.
