In July 2017, IPE conducted an investigation into supply chain pollution in China's dairy industry. The investigation revealed that many domestic and international brands' subsidiary dairy farms and factories have environmental violations relating to fecal and sewage treatment and other environmental matters, but most dairy brands have yet to take responsibility to publicly respond to environmental groups. We hope dairy brands will promote environmental compliance and establish a green dairy supply chain.

In March 2017, IPE began conducting an investigation into pollution along P&G's supply chain in China. It was discovered that a number of the brand's suspected suppliers from the phosphorus chemical industry have exhaust and wastewater over-emissions and procedural violations. We hope that aside from reminding the public to take precautions against smog, P&G can proactively push suppliers in China to comply with environmental laws and regulations.

In October 2016, IPE and Lvse Jiangnan continued their pollution investigation into Toyota Motor's supply chain in China, discovering that a number of automotive component suppliers belonging to Toyota Group have environmental violation records. Moreover, Toyota Motor's wheel hub supplier fails to properly store and treat its industrial solid waste and hazardous waste. In response to these violations, Toyota China breaks the silence with a response that it is currently checking these claims.

In September 2016, Lvse Jiangnan and the Institute of Public & Environmental Affairs conducted an investigative case study on Toyota's supply chain environmental pollution. The investigation shows that Toyota's subsidiary supplier has long exceeded air emission standards and has continually disturbed nearby residents. Despite its proposed goal to "reduce negative factors associated with automobiles as close to zero as possible," Toyota has yet to address its supplier's violations and keep to its environmental protection promise.

In August 2016, the Institute of Public & Environmental Affairs, Lvse Jiangnan and Huai River Guardians conducted a joint investigation, aiming to understand the supply chain management practices behind Disney's meticulously constructed green image. Investigations show that the brand has failed to meet its promises to "actively screen, evaluate and study the direct and indirect impacts its daily operations impose on the environment." Instead, Disney uses licensing as a way of shirking environmental responsibility.

On September 23, 2014, IPE, Lvse Jiangnan, NRDC and Zhaolu Environmental Protection and Commonweal Service Center jointly published the Phase IV Textile Industry Report. The report highlights significant problems with the centralized treatment of printing and dyeing wastewater and suggests that better cooperation between stakeholders is required to establish a system of responsibility for centralized treatment.

Released in Beijing on December 4, 2013 by seven environmental organizations including Zhaolu Environmental Protection and Commonweal Service Center and Lvse Jiangnan, the GCA Phase III Textiles report refers to a large number of printing and dyeing enterprises in violation on the new wastewater discharge standards and requests that brands such as Polo, Uniqlo and Youngor face up to the serious water pollution created by their supply chains.
