Raise taxes on ranchers and other meat traders, they are the biggest environmental polluters

China will raise a tax on environmental pollution.
The world's largest polluter, especially in China, is the meat industry.
Hong Kong, which is part of China since July 1997, is the largest carnivore.
Following the last census in April 2011, China has 1.336.718.015 inhabitants of which are most carnivores. That number is now very definitely grown a lot, partly because the one child policy has been changed to the two-child policy.

If you want to improve your environment, please start on your livestock. Also for animal welfare in China this is very desirable.
