The 500 most polluted cities on earth:
187 of the Top 500 are in China (as well as 100 of the Top 222).
98 are in India.
The EU has 36 of the top 500, and they are all in Poland, Czech, Bosnia, and Macedonia.
Not one is in the US. NONE.
87% the rest are in the rest of Asia. (Iran and Saudi Arabia have 3 in the Top 5).

And now look at this:
2015 carbon dioxide emissions by country:
1. China 10.6 billion tons
2. USA 5.2
3. EU (all) 3.5
4. India 2.5
5. Russia 1.8
(Note: 10.6 > 5.2+3.5+1.8... yes, you read that right... China already spews more than US-EU-Russia combined)

Now check this out:
Under the Paris Agreement, China "promises" (and we can always trust Communist regimes with Social Issue promises 17 years out) to "peak" (meaning increase until it gets there) its emissions at a level "only" 34% higher than current emissions...
(Source: Reuters 6/30/2015 - http://www.reuters.com/article/us-france-china-climatechange-idUSKCN0PA1G420150630)
well 34% of 10.4 bn tons is 3.5 bn tons... which is equal to the entire output by the entire EU combined today. China already spews as much as the US-EU-and-Russia COMBINED, is the most polluted nation on earth... and gets to ADD another EU on top of that... while paying nothing... and the Western world has to cut back, and finance the developing countries.
