On my recent trip tot China I was fortunate enough to meet with a number of Chinese companies and visit Beijing and Hong Kong.
The pollution in Beijing is truly terrible (see here), the smog hangs over the city almost permanently. On a very rare day you may be able to glimpse the blue sky overhead. Hong Kong is a little better, but not much. The Smog rolls in from all the factories in Gaungdong province.
Interestingly though, this is of concern to the people who live and work there. Companies too would like to reduce their emissions and clean up the environment; but they also like the economic growth that swift development has given them.
The best solution that I can see is for the West to sell to China the best technology that we have for reducing emissions. We can't ask China to stop its growth in the iron age with countless millions still poor.
A new Kyoto, based on its old measures will not be ratified. A new approach is needed.
By the by, for the Olympics the Chinese Government are set to close all factories for a month in Beijing Province and ban all private cars. This should do much to reduce the pollution for the games. How Tony Blair must wish he had such powers in this country!
