And it's not just that plastic bags now have a price-tag, China has been implementing plenty of other green initiatives. In 2015, Jilin became the first Chinese province to not only restrict the use of plastic bags, but to also ban their production. Vendors who provide free, non-degradable plastic bags could face a fine of up to 30,000 yuan, or about 4,600 US dollars. And China's capital, Beijing is just one of many regions which is also trying to ride the green wave. And yet despite their best efforts, it's like one step forward and two back. China's recent upsurge in online-retail and food delivery means there's still a huge demand for plastic bags. The 24-hour shopping frenzy on Singles' Day created one and a half billion packages -- worryingly, most of them came in a non-degradable plastic bag. Even in a normal week, an estimated 300 million plastic bags could be used, and that's just for take-out meals ordered online. For all delivery services, China used some 15 billion plastic bags last year.
