China is four years into its war on pollution, and while the skies over many of its cities are bluer and thousands of polluting industries have been closed, many challenges remain. According to China’s Ministry of Ecology and Environment, 16 percent of China’s soil is polluted, 239 of China’s 338 biggest cities failed to meet air quality standards in 2017, and 32 percent of China’s surface water is not clean enough to swim in. To confront these challenges, Chinese citizens and nongovernmental organizations (NGOs) are taking legal action to halt polluters, push local government to be more accountable, and strengthen enforcement of pollution laws—but most lack the legal experience and expertise needed to be successful. A series of workshops held by the Environmental Law Institute earlier this year sought to close this gap by training NGOs and legal professionals in China on best practices for environmental public interest litigation.
