NYC carbon emissions

Cities, even rich ones, perform differently. In this list of 12, 

starting with the dirtiest, New York comes in fifth. 

These are greenhouse gas emissions per person 

(What's with Washington?):

1. Washington, D.C., U.S. — 19.7 tons of CO₂ equivalent
2. Glasgow, UK — 8.4 tons
3. Toronto, Canada — 8.2 tons
4. Shanghai, China — 8.1 tons
5. New York City, U.S. — 7.1 tons
6. Beijing, China — 6.9 tons
7. London, U.K. — 6.2 tons
8. Tokyo, Japan — 4.8 tons
9. Seoul, South Korea — 3.8 tons
10. Barcelona, Spain — 3.4 tons
11. Rio de Janeiro, Brazil — 2.3 tons
12. Sao Paulo, Brazil — 1.5 tons

Cities differ because some have lots of factories, some don't.
Some have more refrigerators, air conditioners, fancy appliances
than others. Some have more modern, tighter buildings, more
office towers, more public transit. (Washington is warmer,
often stifling, is that why it's such an emitter? Can we blame air
conditioning?) npr
