China put forth the clearest set of conditions yet for accepting a binding pledge to cut greenhouse gas emissions after 2020, Bloomberg reported. Xie Zhenhua, head of China’s delegation to this year’s UN climate talks in Durban, South Africa, said that developing countries – including China – should continue their voluntary targets to limit emissions until a new treaty would take effect after 2020. However, any such commitment would depend on five conditions, ranging from developed-country climate aid to an extension of existing rich-country pledges after the current protocol expires. The statements are the most defined set of conditions yet made by China to adopting binding targets. But some analysts say the conditions set by China are nearly irreconcilable with the EU’s position and both may be trying to engineer a stalemate to avoid blame for not extending any emissions limits.
