Effects of environmental policy on consumption: lessons from the Chinese plastic bag regulation
To reduce plastic bag litter, China introduced a nationwide regulation requiring all retailers to charge for plastic shopping bags on 1 June 2008. By using the policy implementation as a natural experiment and collecting individual-level data before and after the implementation, we investigate the impacts of the regulation on consumers’ bag use. We find that the regulation implementation caused a 49 per cent reduction in the use of new bags.
