In September at the United Nations, Chinese President Hu Jintao said that, by 2020, China would reduce carbon emissions by a "notable margin." Contrary to the popular notion that China is anything but green, Hu's speech may be backed up with action. It coincided with accelerated efforts to spend $713 million on "green" initiatives, such as the country's first "zero-emissions city" in Gansu province. It is a significant move as the Chinese government prepares for the worldwide climate-change conference that will take place in Copenhagen this December. But how seriously should the world take Chinese initiatives? NEWSWEEK's Melinda Liu talked to Su Wei, Beijing's top climate-change negotiator at the National Development and Reform Commission (NDRC) to ask about China's official thinking on Copenhagen—and why Hummer is a "garbage brand." Excerpts:

NEWSWEEK: Are you optimistic that developed and developing countries can reach a meaningful agreement at Copenhagen?Su Wei: I've always been optimistic. We're making efforts for a fruitful result at Copenhagen, and that should not be difficult if there is enough political will. However, climate change isn't a problem that can be resolved within one or two years; it's a long-term task.

Is there enough political will within China's government?The Chinese government has been paying a great deal of attention to the climate-change issue in recent years. The country has set up a climate-change leading group headed by Premier Wen Jiabao, and the Chinese government's attitude is serious. According to our plan, by the end of 2010, energy consumption per unit of GDP should be lowered by 20 percent compared with 2005. China's greenhouse-gas emissions will not increase endlessly; there will be a peak. When that peak will occur depends on many factors. However, I personally believe China's emissions will stop increasing by 2050. If everyone discharges an average per capita amount of 10 tons of carbon dioxide [as they do in] the United States, the earth will come to an end.

In parts of Guangdong province, authorities are reportedly turning a blind eye to the pollution produced by some export manufacturers so long as they can keep employing workers. Has the global financial crisis hurt environmental protection efforts?In the implementation of the financial stimulus policy, we've given serious consideration to whether projects with high pollution levels and high emissions should be allowed to operate. Our plan in combating the crisis is consistent with promoting energy conservation, emissions reductions, and environmental benefit. In the plan we allocated $713 million for environmental protection, improvements in energy saving, and projects related to emissions reduction and developing renewable energy. This is quite a big proportion of the $590 billion stimulus package.
