In order to understand the environmental non-compliance issues in wastewater treatment industry, an analysis was conducted using IPE's Pollution Database database and shows that over 3600 wastewater treatment plants (WWTPs) in China have 4961 environmental violation records over a period of 6 years from 2008-2013. On average, each sewage treatment plant has 1.4 violation records. To our disappointment, most of the listed companies in the water industry failed to give a positive response to the pollution allegations.

On June 18th, 2013, the Institute of Public and Environmental Affairs (IPE), together with Lvse Jiangnan, Green Hunan and SynTao Co., Ltd. jointly released the Phase I Green Stocks Investigative Report. The report points out that 17 listed cement companies are in frequent violation of regulations on the discharge of gaseous pollutants and they are also not fulfilling their responsibilities to disclose discharge information.

On March 1st, 2010, IPE identified 175 companies listed on the Hong Kong Exchanges & Clearing Limited (HKEx) with environmental infraction records in the Chinese mainland.
