Of course "others" can too, if by that you mean other countries with a population that is affluent enough to demand green politics. The problem is that these countries only have a small share in global carbon emissions, so even setting lofty goals there will accomplish very little in the big picture.

On the other hand, all the emergent economies have no (internal) political pressure to do much about pollution, much less about CO2 emission. However, what they tend to have in common is that they export a lot products to these affluent countries.
