What Does China Know That We Don't?

New Scientist has reported that Chinese companies are threatening to release vast amounts of a highly potent greenhouse gas, HFC-23, into the atmosphere unless they are paid a hugely profitable amount in carbon credits. They write:

Nobody needs HFC-23. It is a waste by-product of the manufacture of a refrigerant called HCFC-22, used mostly in developing nations. To curb the release of HFC-23 into the atmosphere, the signatories to the Kyoto protocol agreed to pay carbon credits to refrigerant manufacturers that agree to capture and destroy it. The manufacturers can then sell the credits to western companies that want to offset their obligations to cut emissions of other greenhouse gases, under a Kyoto scheme known as the Clean Development Mechanism (CDM).

The offer only applies to HCFC-22 plants that were built before 2000. Even so it has proved highly lucrative. By some estimates, the value of the carbon credits is up to 100 times the cost of incinerating HFC-23. The resulting income of Chinese companies alone is estimated to reach $1.6 billion by 2012. ...

As a result, the "waste gas" HFC-23 has become much more profitable to refrigerant factories than HCFC-22 itself. Watchdog groups like the London-based Environmental Investigation Agency (EIA) say the compensation system ends up providing a strong incentive to overproduce HCFC-22, using methods that maximise the output of HFC-23.

Cutting a long story short, a review was started at the behest of the European Union, a threat was issued to release vast quantities of the gas, and the review was cancelled.

So let's get this clear:

• Billions of dollars, or Euros or something, are being paid to China to not release this gas.
• But that is only logical if releasing the gas is so damaging to us that it is worth paying the blackmail.
• But there is only one atmosphere!
• So if the gas damages us, it must damage China also.
• But China is willing to go ahead anyway.

So either China is suicidal, or:

(I.e., they are bluffing.)
