Big hydro, big solar photovoltaic (PV) and big wind - these are the usual focus of accounts of low carbon technologies in China. But a very different type of innovation - ranging from a farm cooperative in Yunnan, to woodchip and corn pellets in rural Beijing and air-conditioning using just salt and water in Hangzhou and Shenzhen - could be even more significant as examples of how to achieve a low carbon economy and society for China and the world. This report follows a 2007 NESTA report that profiled eight disruptive low carbon innovators from the UK, and explores the particular importance of this type of innovation to China with seven case studies. These are the Chinese 'Game-Changers', each of which has developed a low carbon innovation that has the potential to make a significant contribution to emissions reductions and the move to a low carbon society.
