how we do it
LONGi contributes to climate action by reducing emissions across its operations and taking responsibility for environmental and societal impacts throughout its value chain. The company has established emissions reduction targets aligned with international frameworks and continues to increase the share of renewable electricity used in its operations. Its approach also extends to areas such as biodiversity and energy access, supported by structured governance, transparent reporting, and collaboration with international organizations.
LONGi has established emissions reduction targets aligned with the Science Based Targets initiative, covering both operations and the broader value chain. The company is committed to reaching net-zero emissions by 2050, supported by measurable progress across energy use, efficiency, and environmental impact.
LONGi is steadily transitioning toward lower-carbon manufacturing. In 2025, Scope 1 and 2 emissions were 7.9% lower than in 2024, and renewable electricity reached 52.4% of consumption across all facilities.
Efficiency is built into how we manufacture. We implemented 322 technical electricity efficiency upgrades across our production sites in 2025, resulting in roughly 392 million kWh in expected annual electricity savings.
With approximately 90% of our emissions linked to Scope 3, we actively focus on upstream impacts across our suppliers and materials. Our net-zero value chain target by 2050 is fully aligned with the Science Based Targets initiative (SBTi).
We carefully manage our operations to avoid and minimize impact on local ecosystems. We are committed to achieving no net loss of biodiversity by 2050, and we aim to deliver a net positive biodiversity impact by restoring and enhancing ecosystems by 2060.
Standardized measurement ensures our data is reliable and comparable. We calculate our product emissions using lifecycle-based carbon assessments (ISO 14067) and hold 64 product carbon footprint certifications for wafers and modules, verified under international standards.
LONGi reduces operational emissions through continuous optimization of manufacturing processes, targeted efficiency programs, and increased use of renewable electricity. Execution is supported by structured energy management systems and performance tracking across production sites. Selected production sites are developed as zero-carbon factories.
The Jiaxing and Wuhu manufacturing bases are certified under ISO 14068 and combine renewable electricity sourcing, energy efficiency measures, and emissions management, serving as benchmarks for low-carbon manufacturing within the photovoltaic industry.
LONGi addresses upstream emissions by embedding ESG criteria into procurement and working directly with suppliers on emissions reduction. Supplier management is based on full ESG due diligence coverage across the primary supplier base, including 100% due diligence on conflict-related minerals. Requirements are formalized through a Supplier Code of Conduct and supported by ISO 20400-certified procurement processes. Implementation includes structured supplier engagement and capability building.
In 2025, 97 supply chain enterprises were promoted to carbon verification. In parallel, training initiatives based on the UN Guiding Principles support risk identification and mitigation across the supply chain.
LONGi integrates climate targets into a three-level ESG governance structure, with oversight by the board’s Strategy and Sustainability Committee, management-level coordination, and implementation by dedicated ESG teams. A three-lines-of-defense framework supports risk identification and management across operations and the supply chain.
Carbon data management and traceability systems support performance monitoring and reporting. LONGi also translates its ESG requirements into supplier assessments, carbon audits, and training programs. In 2024, the company conducted 50 supplier carbon audits, while 228 suppliers registered on the LONGi eLearn platform and 65 training sessions were delivered. These measures help embed ESG requirements into operational processes and supplier management.
LONGi’s ESG performance is assessed through leading international frameworks, providing transparent, comparable data on climate impact, supply chain responsibility, and corporate governance.
LONGi’s ESG performance is backed by verifiable data and certifications, enabling faster approvals, reduced risk, and alignment with regulatory and investor requirements.
LONGi provides product-level carbon footprint certifications across major markets,including ISO 14067 and national frameworks such as PPE2. This ensures that modules meet documentation requirements for regulated tenders and procurement processes.
ESG due diligence covers all new suppliers and high-risk suppliers, supported bystructured audits and traceability systems. Supplier requirements are defined through contractual standards and monitored through ongoing verification processes.
LONGi is rated by major ESG assessment bodies, including EcoVadis, S&P GlobalCSA, CDP, and MSCI. These ratings provide comparable benchmarks used by investors, lenders, and procurement teams.
