China's Cities

China has a rather low level of urbanization today (about 53%), compared with 75-80% in the U.S. and Europe – but this is changing very rapidly.

Some 300-500 million Chinese citizens will move to urban areas over the next twenty years. Urban residents use 2 to 3 times as much commercial (i.e., non-biomass) energy as rural ones, and Chinese cities already face severe environmental problems.

I have been working in Chinese cities since 1990, on a series of projects:

Pollution control for coal combustion

Urban air pollution control

。Guangzhou (NOx)
。Guiyang (SO2)

Clean Energy

I've worked on landfill gas, energy efficiency (for industry and buildings), and various other energy projects in China.
