China's government has issued a list of “behavioural standards” it expects citizens to adhere to in order to try to reduce environmental damage. The eight examples of bad environmental behaviour include cooking by barbecue, setting off fireworks and burning garbage. The public is also urged to walk to work or travel by bicycle and to buy goods with less packaging. Citizens should also report any environmental bad behaviour they see in others. A recent local government report on the life-threatening air pollution in Beijing said 31% comes from vehicles, 22.4% from coal burning and 18.1% from industry.
