At the same time, Shenzhen will also strictly control the use of high-VOC paints and organic waste gas emissions for new furniture manufacturing projects, shut down spraying production lines that are unlicensed, unlicensed, and without environmental approvals; and introduce environmental protection for voluntary furniture. The sign system encourages furniture produced and sold in Shenzhen to obtain environmental protection signs; and from 2015 onwards, a compulsory furniture environmental protection sign system will be implemented.
In addition, Shenzhen will also issue circulars prohibiting the sale and use of highly volatile wood lacquers and architectural coatings to reduce the unorganized emissions of volatile organic compounds in construction projects.
