There's a repeated pattern there, where developed nations got the benefit of decades of uncurbed consumption, then they belatedly get to work trying to curb it, and developing nations that finally would have had a turn are expected to follow suit. It's similar with greenhouse gas emissions.
My idea for dealing with this kind of thing involves all the major consumer nations coming together to set a common trade standard with regard to other nations, which standards could involve things like environmental compliance and labor standards, where meeting the standards would assure low trade tariffs (and failing to meet them would mean losing economical access to ALL the major consumer nations). Start out year one with a very easy standard, then ramp it up a bit every year, always keep each incremental step small enough that the easiest path will be compliance. Doing that, other nations can be coaxed to come up to advanced-nation standards much faster than they otherwise would.
The problem, though, is that the "new world order" loons lose their shit any time you talk about setting common policy on anything with other nations, insisting that it's a violation of American First principles and a breach of our sovereignty. So, they'll derail any effort like that, leaving the advanced nations in a situation where it's every country for itself, and countries like China can easily play us off against each other. For example, if Germany and the US each have separate policy with regard to China, then each knows that if it raises trade barriers against China on, say, automotive components, in order to punish China for bad conduct, the other will then have cheaper components in its cars and will be more competitive on the global market. As long as people can be kept paranoid about giving up sovereignty to any international organization, countries like China know that little will be done to confront them, because whoever tried to go it alone that way would only end up hurting itself.
