Top officials yesterday unveiled a seven-year plan to cut Hong Kong's notorious roadside air pollution, while admitting some of the targets might be hard to meet.
Billed as an air-quality roadmap to 2020, the plan says that if all measures are fully introduced, roadside pollution will begin to drop in the next two to three years, and see significant improvement in four to five.
