Of course, China can learn from the experiences of Europe and the United States, where market-based trading institutions are already firmly established.

Just think about it, if every province in China sets up a carbon trading center...

Also that night, a French public relations manager said his company offers niche services by linking carbon control and social media together. "What we are doing now is to brand green images of my clients by engaging the young people via social media," he said.

Such new trends have also captured the attention of China's academia. Zheng Baowei, a professor from Renmin University of China, has been involved in studies on climate change and communication since the Copenhagen summit in 2009. Now, he has set up a research center on the issue and three students are doing this cross-disciplinary post-graduate course.

With the 12-day United Nations climate change talks in Lima, Peru, in full swing, provocative green discussions and debates are warming up in Paris and Brussels. Compared with the fierce price-comparison process in the pavilion across the Atlantic, which will move to a decisive stage this week, the dialogues involving more than 400 representatives from China and Europe are more friendly, forward-looking and practical.

Their collaboration is dotted by Brussels welcoming the first group of 35 BYD taxis since October which are electricity-powered and, of course, made in China.
