Supplier Screening

What is supplier screening?

Supplier screening refers to the process by which brands and companies use the Blue Map Database to check whether their suppliers have supervision records.

What is the recommended scope of a supplier screening?

The scope of a supplier screening ideally covers all affiliated companies up and down the production supply chain, including but not limited to production facilities, raw material providers, production-related service providers (such as centralized wastewater treatment facilities, solid waste treatment facilities or thermal power plants), and potential suppliers, as well as any subordinate factories and enterprises in which the brand has invested.

How often should a brand screen its suppliers?

The Blue Map Database is updated in real-time and will continuously collect enterprise violation records issued by official sources. Therefore, IPE recommends that brands screen their supplier lists on at least a quarterly basis, or to register a brand account to receive automatic updates regarding their suppliers using the Blue EcoChain tool.

How do I conduct supplier screening?

Single search: Register an account on the Blue Map Database for free, enter supplier names or keywords one at a time (suitable for companies with a small number of suppliers).

Batch search: Register an account for free; then upload a supplier list using the Excel template. The system will automatically find suppliers’ violation records, and promptly provide information for suppliers that publish this data.

Information Disclosure

What is information disclosure?

Information disclosure refers to the process by which enterprises may disclose information regarding the reasons for their violations and any corrective actions they have taken in response. Enterprises can also disclose information regarding how they continue to improve their performance as well as data regarding pollutant and greenhouse gas emissions.

Who provides public explanation?

Why should enterprises provide explanation?

The Blue Map Database aims at provide an environmental information disclosure platform for enterprises and facilities to help multistakeholders in gaining a timely and comprehensive understanding of their rectification measures for non-compliant issues and the current status of environmental compliance, to assist the government, brand companies, financial institutions, the general public and other interested parties in formulating policies, practicing green procurement, green investment and financing, carrying out public supervision, etc., and to guide and motivate enterprises to continuously improve their environmental performance and achieve green and low carbon transformation.

Laws and regulations in China also encourage environmental information disclosure, for more details see: Legal and Regulatory Requirements for Corporate Environmental Information Disclosure(Chinese)

For enterprises that have already submitted rectification statements and paid penalties to the issuing department, why is it still important to provide explanation/feedback on the Blue Map Database?

The Blue Map Database is an open data platform that helps environmental organizations, the general public, brand companies, industry associations, media, financial institutions, ESG investors, research institutions and other parties to better understand the reasons for companies' violations, corrective actions taken, and their current compliance status.

By providing explanation on this platform, enterprises signal to the parties listed above that they are aware of their violation records and have taken steps to respond and assume environmental responsibility and accountability.

On the other hand, if ecology and environmental departments already publicly disclosed follow-up information on relevant records via their own websites, the Blue Map Database will also update the information accordingly. If companies have already made disclosures on other platforms, they could provide relevant URL links directly to Blue Map Database for synchronisation.

How to submit enterprise feedback/explanation to the Blue Map Database?

Step 1. Register a corporate user account on the Blue Map website;

Step 2. Once logged in, go to "My Green Choice", click on "Information Disclosure" and submit explanations and upload supporting documents based on instructions on the webpage.

For details, please see this page: http://wwwen.ipe.org.cn/GreenSupplyChain/GCA_Audit.html.

Do enterprises need to pay for providing public explanation?

No payment is required for providing public explanations.

Where can I find the explanation provided on the IPE website? Who can see it?

Public explanation will be displayed under the “Enterprise Feedback” tab on the Records page, and everyone who visits the website can see it.

GCA Audit/ Record Removal

What is GCA audit or record removal?

"GCA Audit" refers to an open and transparent mechanism for companies to verify the effectiveness of corrective actions regarding previous violations and remove records from the Blue Map Database.GCA audit is conducted in line with the basic requirements of corporate compliance with laws and regulations and in accordance with the Green Choice Audit criteria, with the audit report displayed on the Blue Map website (except for those parts that involve commercial secrets) for public supervision. GCA audit comprises two forms: off-site document review (carried out by IPE staff) and on-site GCA audit (carried out by qualified third-party audit companies who may negotiate the fees with the enterprise). IPE does not charge fees in any of the auditing process.

What is the difference between GCA Audit and information disclosure?

“GCA Audit” refers to the process of removing violation records from the Blue Map Database, whereas “information disclosure” means enterprise publicly disclose information via the Blue Map Database and will not necessarily suffice to remove a record.

How do I remove a record? Do I need to pay to do so?

GCA audit comprises two forms: off-site document review (carried out by IPE staff) and on-site GCA audit (carried out by qualified third-party audit companies who may negotiate the fees with the enterprise). IPE does not charge fees in any of the auditing process.

CITI (Corporate Information Transparency Index)

What is CITI evaluation?

The Corporate Information Transparency Index (CITI) is the world’s first quantitative assessment system based on brand’s environmental management of their supply chains in China, jointly developed by IPE and the Natural Resources Defense Council (NRDC) in 2014. The index uses government supervision data, online monitoring data, third party environmental audits, and other public information to dynamically assess the environmental performance of brands’ supply chains. Focused strictly on supply chain impacts, where the heaviest environmental impacts and carbon hotspots lie, the CITI Evaluation makes an important complementary contribution to broader global sustainability initiatives and reporting indices developed for the private sector. It is also structured to provide a step-by-step roadmap for the private sector to improve their sourcing programs and incorporate environmental behavior and carbon footprints into the selection of manufacturers for their goods.

What is the scope of CITI evaluation?

CITI evaluation primarily focuses on consumer-facing companies that have a sizeable supply chain in China. In 2025, the evaluation covered 800 brands across 23 industries. As corporate environmental information disclosure in China continues to improve, the CITI evaluation will continue to expand to more industries.

What are the major areas that CITI evaluates?

The evaluation examines the following five areas:

1. Management Mechanism: Guiding companies to pay attention to the impact of their supply chain production processes on the local environment, establish green supply chain management mechanisms, and respond to stakeholder concerns
2. Compliance and Corrective Action: Guiding companies to focus on supply chain environmental compliance, take corrective and remedial actions for negative impacts already caused, disclose progress, and continuously monitor environmental risks throughout the supply chain
3.Resource Consumption and Pollutant Reduction: Guiding companies to manage processes such as the use of chemicals, pollutant emissions, waste disposal, and the exploitation and utilization of natural resources in their supply chains, minimize their impacts on air, water, soil, ecosystems, and biodiversity
4. Energy Use and Climate Action: Guiding companies to improve the efficiency of energy resource use and reduce greenhouse gas emissions along the value chain
5. Stakeholder Green Choice: Guiding companies to promote the green transition of value chain partners and help stakeholders make green choices

Carbon and PRTR

What is Carbon Disclosure?

Carbon data disclosure refers to the public reporting of an enterprise‘s annual greenhouse gas emissions, climate targets and progress, carbon intensity, energy consumption, carbon assets and other data. Carbon data is the key to achieve carbon peaking and carbon neutrality. Mainstream environmental information disclosure guidelines in China and internationally all put forward clear requirements for carbon data disclosure.Enterprises can calculate and publicly disclose the above data via the Blue Map, identify hot emission hotspots, set science-based emission reduction targets, accelerate low-carbon transition, improve market competitiveness, and achieve sustainable development. The disclosure of carbon data also enables multi-stakeholder participation in the global climate governance and the “race to zero”.

For more details, please see this webpage:https://wwwen.ipe.org.cn/GreenSupplyChain/CarbonPRTR.aspx

What is a PRTR system?

"A Pollutant Release and Transfer Register (PRTR) is an environmental database or inventory of potentially hazardous substances and/or pollutants released to air, water and soil and transferred off-site for treatment or disposal." - UNECE

In August 2013, IPE established a voluntary disclosure platform for PRTR data in China, and encourages high environmental impact enterprises to disclose their resource and chemical use data, emissions and transfer data, particularly data regarding hazardous chemicals. To contribute to the Kunming-Montreal Global Biodiversity Framework’s 2030 targets, IPE develops a module on biodiversity, which aims to empower corporates to assess the impacts on ecosystem, participate in biodiversity conservation.
