Government ought to strengthen supervision and management by stipulating national environmental standards on packaging for takeout food, he said in an interview with People.cn at the ongoing annual political consultative session in Beijing.

He also urged that delivery service platforms and related catering enterprises be made responsible for reducing takeout packages and disposable tableware.

To achieve that, incentives such as discounts, perks and delivery fee deductions should be offered to promote people to embrace the change, Cao suggested

Other measures he mentioned in handling the problem are improving people's awareness of environmental protection, advancing garbage sorting as well as recycling and building up an accountability system for polluters.
