A senior negotiator informed Reuters that China is willing to include its voluntary carbon emissions target in a binding UN resolution, which could potentially put pressure on developed countries to extend the Kyoto Protocol. The success of UN climate talks in Mexico's Cancun beach resort relies on reaching an agreement on solidifying national emissions targets beyond 2012 when the current round of Kyoto carbon caps expire. China's willingness to compromise is contingent on the United States agreeing to enforceable emissions reductions and an extension of the Kyoto Protocol, which currently applies to nearly 40 developed countries excluding the US. Developing countries are in favor of continuing the protocol, while industrialized supporters such as Japan, Russia, and Canada prefer a separate agreement that encompasses all nations. China had previously rejected the idea of making its domestic emissions goals legally binding, unlike industrialized nations. Huang Huikang, the Chinese Foreign Ministry's representative for climate change discussions, stated that a resolution could be crafted which would be enforceable on China. He mentioned the possibility of a legally binding decision under the UN Climate Convention and expressed willingness to consider different forms for this. He emphasized the importance of China's efforts being integrated into global initiatives and suggested that addressing concerns did not require scrapping the Kyoto Protocol and beginning anew. Jennifer Morgan from the World Resources Institute in Washington described the proposal as a significant development, calling it a "gamechanger." Alden Meyer of the Union of Concerned Scientists also expressed optimism, stating that while the details are important, this is a promising step forward. China's chief negotiator Xie Zhenhua later explained that China's targets could be aligned with the Convention, allowing developing countries to voluntarily commit to emission reductions using their own resources. Huang stated that China would not change its stance on insisting that new emissions targets be included in an extended Kyoto agreement. China has always maintained that its efforts to reduce emissions are only binding domestically and cannot be included in international agreements. Huang acknowledged that China is now willing to be fully part of the international effort and sees this as a compromise. However, he emphasized that when it comes to the Kyoto agreement, there is no room for compromise. Developing countries, such as China, the largest carbon emitter globally, made a commitment at a summit in Copenhagen to voluntarily take action to limit the growth of their emissions. China specifically vowed to decrease its "carbon intensity," which is the quantity of carbon dioxide released for each unit of economic growth. The goal is to lower this intensity by 40-45 percent by the year 2020 compared to levels in 2005. Huang suggested that this intensity target could be included in a resolution.
