Verifying upstream material origins and compliance with environmental and social standards requires time and documentation, while project timelines remain tight. The ability to demonstrate a transparent and audited supply chain is therefore becoming a prerequisite for participation in large-scale projects in Europe.
May 20, 2026
European solar procurement is entering a phase where cost is no longer the sole determining factor. Regulatory frameworks such as the Corporate Sustainability Reporting Directive (CSRD) and the Net-Zero Industry Act (NZIA) are increasing the weight of non-price criteria in project evaluation, particularly in public tenders. As a result, traceability and verified ESG compliance are becoming central to supplier selection and project bankability.
Manufacturers are responding by expanding audit coverage and embedding ESG criteria directly into procurement systems. Audits of the primary supplier base at LONGi reached 100 percent coverage during the 2024 reporting period, ensuring that all tier-1 partners undergo systematic vetting for environmental and social compliance. This documented baseline can be used by downstream partners in their own reporting and tender submissions.
