Measurable sustainability in solar manufacturing

LONGi calculates Product Carbon Footprints (PCF) in line with ISO 14067, covering the full cradle-to-gate lifecycle. As module efficiency increases and manufacturing is powered by more renewable energy, the lifecycle carbon intensity per watt-peak falls year-on-year. Detailed PCF documentation is available on request and disclosed in LONGi's annual Sustainability Report.

Yes. LONGi has submitted targets to the Science Based Targets initiative (SBTi), aligning its reduction pathway with the Paris Agreement's 1.5°C scenario. The company has also joined RE100 (commitment to 100% renewable electricity) and EP100 (doubling energy productivity), with systematic reduction plans covering Scope 1, 2, and 3 emissions across operations and the full value chain.

LONGi requires key Tier-1 suppliers to set their own carbon reduction targets and obtain ISO 14001 certification. Its supplier capacity-building programme — targeting 95% procurement coverage by 2028 — includes dedicated environmental management training, GHG reporting guidance, and support for certification. LONGi also actively promotes the procurement of green, low-carbon input materials, including granular silicon produced with renewable energy.

LONGi has committed to 100% renewable electricity across its global operations through the RE100 initiative. The company sources green power via renewable energy certificates (RECs), on-site distributed generation, and power purchase agreements. Its energy management system is certified to ISO 50001, and energy intensity per unit of output is tracked and reported annually.

LONGi's existing GHG accounting framework — covering Scope 1 and 2 emissions at production facility level — provides the data foundation required for CBAM embedded-carbon declarations. Customers importing LONGi products into the EU can request product-level emissions documentation directly from their LONGi account manager. LONGi continues to monitor evolving CBAM implementation guidance and will update its reporting outputs accordingly.

LONGi's due diligence framework is aligned with the requirements of the Lieferkettensorgfaltspflichtengesetz (LkSG). Risk-based human rights and environmental due diligence is conducted across the supply chain, grievance channels are open to external stakeholders, and results are disclosed in the annual Sustainability Report. LONGi's compliance management system is independently certified to ISO 37301.

The EU Corporate Sustainability Due Diligence Directive requires companies to identify and address adverse impacts in their upstream value chains. LONGi proactively supports downstream compliance by providing supply chain transparency data, traceability reports, supplier audit results, and ESG due diligence documentation. LONGi's supplier questionnaire covers all CSDDD-relevant topics: forced labour, environmental compliance, business ethics, and human rights.

LONGi's annual Sustainability Report is prepared with reference to GRI Standards and discloses verified data on GHG emissions, supply chain audits, human rights performance, and governance. Customers in scope for the Corporate Sustainability Reporting Directive can draw on LONGi's disclosures, product carbon footprint documentation, and traceability reports to populate upstream data points in their own double-materiality assessments and value-chain disclosures.

Forced labour prevention is a non-negotiable red line in LONGi's supply chain policy. The company's traceability system — independently verified by SGS, PI Berlin, TÜV Rheinland, CEA, and Sinovoltaics — provides the documentary evidence needed to demonstrate that products entering the EU market are free from forced labour. In 2024, all silicon supplier on-site audits confirmed zero instances of forced or child labour.

Yes. LONGi Solar Australia publishes an annual Modern Slavery Statement under Australia's Modern Slavery Act 2018, covering supply chain risks, mitigation actions, governance accountability, and improvement commitments. The statement is approved at board level and publicly available. LONGi's global human rights due diligence framework is aligned with the UN Guiding Principles on Business and Human Rights (UNGPs) and applies consistently across all operating jurisdictions.
