China has pledged to be carbon neutral by 2060 -- and its citizens are helping industries across the country reach that goal. Environmentalist Ma Jun introduces the Blue Map, an app that empowers people to report pollution violations in their communities and track real-time environmental data, holding emitters accountable and helping companies along the global supply chain make informed sourcing decisions. Hear how the app uses the power of transparency to motivate more than 14,000 factories (so far) to clean up.
