BEIJING (AP) — A Chinese environmental group launched a smartphone app on Monday that tracks and shames polluting factories, highlighting how the country is making environmental data more available and enabling public monitoring of companies that pollute.

The app gives, where available, hourly updates on emissions reported by factories to local authorities and shows the plants as color-coded points on a map, with violators of emissions limits in red. It also gives government air pollution data for areas throughout the country.
