Globalised manufacturing and procurement mean that a lot of high-polluting, heavy duty jobs are transferred to China. We will ask major companies, such as Wal-Mart, Microsoft and IBM to put pressure on their Chinese suppliers.

If Alibaba cannot become a Microsoft or Wal-Mart, I will regret it for the rest of my life.

If major companies sourcing in developing countries care only about price and quality, local suppliers will be lured to cut corners on environmental standards to win contracts.

I hope they can see that as a consumer, if they express themselves, they may make an impact and leverage their impact on the brands, and the brands can leverage their buying power on tens of thousands of polluters - suppliers - in China.

Brands who come to China, often they just care about price - so they actually drive the suppliers to cut corners on environmental standards to win a contract.

China's energy is very much focused on coal, and the economy is very focused on heavy industry, which is carbon intensive, so restructuring won't be easy.
