About LONGi

LONGi Green Sustainable Supply Chain

On April 24, 2024, the European Parliament approved the "EU Corporate Sustainability Due Diligence Directive" (CSDDD) by voting. In response to the CSDDD, the EU’s "Corporate Sustainability Reporting Directive" (CSRD), as well as an increasing number of regulations on sustainable procurement and information disclosure, LONGi, as a world-leading photovoltaic company, has attracted more and more attention from all kinds of customers in terms of its supply chain environment risk control in global markets. Given that LONGi has numerous suppliers, extensive procurement categories, complicated transactions, and differentiated supplier capabilities, it started cooperation with the Institute of Public & Environmental Affairs (IPE) in 2019. Through the "Records" and "Supply Chain" modules on the IPE platform, LONGi is able to monitor the environmental compliance performance of suppliers in real time. With the help of the platform, LONGi facilitates the environmentally underperforming suppliers to rectify or remove incompliance and go through the IPE’s GCA audit, so as to improve the environmental performance and build a green and compliant supplier team.
