Smog incentives hard to introduce

Obstacles include defining targeted groups and sources of funding

A survey that found majority support for issuing incentives and subsidies for people working outdoors on smoggy days reflects growing approval for improving worker conditions but it is not an easy goal to reach, experts said.

The survey was conducted by the labor union in Zhengzhou, capital of Henan province in December, when the vast northern region had been blanketed by heavy smog. The union is part of the All-China Federation of Trade Unions, the country's top labor organization.
