Plastic Bag Charge Reduces Consumption by 50% in China
According to this Science Daily article, China's 2008 ordinance against free plastic bags has resulted in reduced plastic bag consumption and increased plastic bag re-use. The thesis that the article relies on also found that "there is further room for improvement. What's most important is to make sure that the ordinance is complied with."
The lack of enforcement with regard to China's plastic bag law has been an ongoing problem, so this news is very encouraging!
