ISG 0524 Paul Krugman: Empire of Carbon

[Just JJ]

summary
...China plays a key role which has become the largest producer of carbon dioxide.

I would say "China has become the largest producer of carbon dioxide." or "China has played a key role as the largest producer of carbon dioxide.". What do you say?

What a about "China has played a key role among the main economic entities" ??

Words:
1. not so much ... as ...: If you say that sb's words go unheard, you're expressing criticism because sb refuses to pay attention to what is said or take it into consideration.

The explanation does not make sense to me.

Oops. I copied the wrong one. Here is the correct one.

1. not so much ... as ...: If you say that sth is not so much one thing as another, you mean that it is more like the second thing than the first.

My summary:

... it’s unfair to place constrains on China which developed countries didn’t face during their development;

I think it should be "constraints", right? In all the dictionaries I looked up, "constrain" is a verb.

You're right. Thanks for pointing it out.
