In 2006, he founded the Institute of Public & Environmental Affairs (IPE), and led the development and launch of China’s first environmental public database, as well as the Blue Map, a mobile app that visualizes air, water, ocean, and soil quality data to help the public monitor corporate emissions, use “micro-reports” against environmental violations and polluting rivers, and facilitate garbage sorting and recycling.
