"There are challenges in implementing the law that imposes a tax of VND 40,000 per kg on the production of non-biodegradable plastic bags. Small-scale enterprises and household businesses can easily evade this tax, leading to rampant production of these bags," said Mr. Le Hoai Nam, Deputy Director of the Department of Environment under the Ministry of Agriculture and Environment, at a seminar on promoting sustainable production and consumption through eco-labels held on August 27th.
