In recent days, supermarkets in Shenzhen have initiated new environmentally-friendly shopping bag policies.

Rainbow and CR Vanguard Supermarkets have respectively been touting their new bag policies, which limit bags for consumers. Metro has also introduced its plan to charge shoppers for shopping bag on charge methods, while Wal-Mart launched its plan last year to sell canvas shopping bags at low prices.

At the Rainbow supermarkets, customers can also purchase a fashionable shopping bag for RMB1 when they spend over RMB100.

According to the China Retail and Franchise Association, the shopping bags consumed in the entire supermarket industry are worth RMB5 billion every year. And a 8,000-sqm supermarket can use up shopping bags worth RMB400,000 in a year.
