The row over hydrofluorocarbon-23 offsets – which have a much greater warming effect than carbon dioxide and linger in the atmosphere for 200 years – has intensified before international climate negotiations in Durban this month.
Since 2005, Chinese firms have received the bulk of the $6bn in carbon credits for the reduction of these gases, which are produced in the manufacturing of refrigerant chemicals. The money has mostly come from European firms that have bought the offsets under the clean development mechanism, but this source of funding will come to an end next year. The EU has banned HFC-23 offsets because they are inefficient: the value of credits is 70 times the cost of destroying HFC-23 gases.
There are also widespread suspicions that Chinese and Korean firms have cynically created hydrofluorocarbon facilities in order to qualify for credits, which can generate twice as much income as selling the refrigerant. But Europe's decision has angered Chinese officials responsible for administering the system, which has generated $1.3bn in tax revenues for the state.
