No, I'm not kidding.
China, which rejects criticism that it is doing too little to confront climate change, says that its population is now 1.3 billion against 1.6 billion if it had not imposed tough birth control measures in the late 1970s.
The number of births avoided equals the entire population of the United States. Beijing says that fewer people means less demand for energy and lower emissions of heat-trapping gases from burning fossil fuels.
"This is only an illustration of the actions we have taken," said Su Wei, a senior Foreign Ministry official heading China's delegation to the 158-nation talks from Aug 27-31.
He told Reuters that Beijing was not arguing that its policy was a model for others to follow in a global drive to avert ever more chaotic weather patterns, droughts, floods, erosion and rising ocean levels.
But avoiding 300 million births "means we averted 1.3 billion tonnes of carbon dioxide in 2005" based on average world per capital emissions of 4.2 tonnes, he said.
Pro-abortion global warming zealots in this country should have to choose sides on this one.
