CDP operates the world’s sole independent environmental disclosure system, evaluating thousands of companies annually. In 2025, nearly 20,000 companies were scored out of more than 22,100 that reported through CDP’s platform. That same year, 640 investors managing $127 trillion in assets requested CDP to collect data on environmental impacts, risks, and opportunities. CDP assesses companies based on the depth of their reporting, understanding of environmental risks, and evidence of best practices, including ambitious target-setting and verified actions.
LONGi recognizes water as not only an essential resource for production but also a fundamental pillar for ecosystem health and community prosperity. The company has consistently integrated water resource management into the core of its corporate sustainable development strategy, establishing and implementing systematic water management policies that span the entire process, from production operations to the supply chain. LONGi believes that transparent communication fosters stakeholder trust and enables collective efforts to address global water challenges. Since 2021, LONGi has actively participated in CDP’s Water Security and Climate Change questionnaires, disclosing its ESG management goals and progress. After initially achieving a leadership score (A-) in water security, LONGi continued to invest significantly in water resource management. In 2025, the company earned the leadership score in the water security questionnaire for the second consecutive year and was included in CDP’s esteemed annual ‘A’ List.
In 2024, LONGi strengthened its sustainable management of water resource utilization and improved water efficiency by establishing water resource management policies and water-saving requirements to reduce wastewater generation and discharge. During operations, LONGi optimized its water use structure and advanced water stress assessments to ensure the rational development and efficient utilization of regional water resources. This was achieved through water-saving technological upgrades, wastewater treatment and reuse projects, and other initiatives aimed at improving water resource efficiency at production sites while minimizing wastewater discharge. In 2024, LONGi conducted water resource risk assessments at all operational locations, formulated water-saving policies and plans, and set clear water-saving targets. The Group’s overall water use intensity target for 2024 was to decrease by 13.8% compared to 2023, with the actual reduction surpassing expectations at 24.8%.
Furthermore, LONGi monitors the water footprint of its products and has joined the LWFI (Low Water Footprint Initiative), collaborating with value chain partners to alleviate local water resource pressures. The company establishes water footprint management plans by product type, monitors the water use intensity of products, and explores the development of “zero wastewater discharge” factories. In 2024, by analyzing the water-saving potential across all production stages and implementing alternative water measures such as gray water recycling, concentrated water recycling, and rainwater recycling, LONGi achieved a significant reduction in water use intensity for monocrystalline silicon, wafers, and cells compared to 2023. Notably, the cell sector saw an actual reduction of 44.5%.
Water is the source of life and the cornerstone of sustainable development. LONGi remains steadfast in its commitment to water security, adhering to high standards and driving efficient water resource utilization through technological innovation. The company is dedicated to protecting every precious drop of water on this blue planet, ensuring a sustainable future for humanity.
