There was less-than-subtle finger-pointing at China in the Sept. 22 front-page article “Big Oil’s heirs join call for action as climate summit opens.” An ordinary traveler to China, I witnessed that country’s practices concerning the environment.

In Beijing and other cities, drivers are not allowed on the road every day. License plate numbers determine which days a car can be on the road.

Relatively well-off Chinese live in small spaces, using far less energy than a U.S. family. A family of three or more might occupy 700 square feet.

Traditional restaurants serve tiny portions (in stir fry) of animals such as cow and lamb, the raising of which is a major contributor to climate change. In agricultural southern China, crops are raised without petrochemical fertilizers. I also did not see any large combines or gasoline-powered farm machinery.

Without diminishing the importance of international cooperation regarding carbon dioxide, let’s acknowledge that the average Chinese is leaving a much smaller environmental footprint than the average American.
