Operational emissions in solar manufacturing reduced by 37 percent in 2024

47.5 percent renewable energy use and efficiency gains reduced carbon intensity

Operational greenhouse gas emissions at LONGi declined by 37 percent during the 2024 fiscal year, according to the latest sustainability reporting data. The reduction covers Scope 1 and Scope 2 emissions across global production bases, including sites in China and Southeast Asia. These results align with the company's 2024–2025 Climate Action White Paper and its commitment to international disclosure standards.

This reduction reflects a broader shift toward low-carbon manufacturing, where measurable emissions data and renewable energy integration are becoming key requirements in solar procurement.

European procurement officers and engineering, procurement, and construction (EPC) companies increasingly require documented evidence of low-carbon production to comply with the Corporate Sustainability Reporting Directive (CSRD). This makes operational performance a key selection criterion for suppliers. They must demonstrate concrete progress in decarbonization to remain competitive in large-scale public and private tenders.  

LONGi’s manufacturing strategy reflects this shift through renewable energy integration and process-level efficiency improvements.

Renewable energy usage reached 4.746 billion kWh in solar manufacturing

Renewable electricity consumption accounted for 47.5 percent of the total energy mix in 2024. Total green power usage reached 4.746 billion kWh, providing a stable energy source for the production of silicon wafers and modules. The transition to renewable power sources directly impacts the carbon footprint of every solar component manufactured for the European market.

Strategy documents indicate that the group focused on securing high-quality renewable energy certificates and expanding on-site solar installations. These measures allowed factories to maintain high production outputs while reducing their reliance on fossil-fuel-based grid electricity. The current energy mix supports the long-term roadmap toward Net Zero operations and provides a verified baseline for sustainability audits.

Energy consumption per unit decreased by 10.7 percent through technical improvements

Engineers implemented 477 separate energy-saving technical transformation projects across the group's manufacturing facilities. These initiatives resulted in a 10.7 percent year-on-year decrease in electricity consumption per unit of production. The saved electricity amounted to approximately 426 million kWh, which prevented the emission of 250,000 tons of greenhouse gases.

Operational improvements focused on optimizing heat recovery systems and upgrading high-efficiency motors in the production lines. The internal target for electricity unit consumption was exceeded, demonstrating that process-level innovations can deliver measurable environmental results. Efficiency gains were recorded in several key production areas, including wafer slicing and module assembly.

Carbon footprint certifications provide verified data for 53 solar product lines

Transparency in the supply chain is maintained through 53 global carbon footprint certifications. These certificates cover silicon wafers and solar modules along with hydrogen energy products. Verification from third-party organizations ensures that the 37 percent reduction in operational emissions is reflected in accurate and reliable data for professional buyers.

The certifications meet specific national standards, including those required for the French and South Korean markets. Verified data allow European partners to calculate the environmental impact of their projects with high precision. LONGi continues to align its reporting with the TPT and IFRS S2 frameworks to ensure that all disclosures meet the evolving expectations of the global financial and energy sectors.

Measurable emission reductions based on renewable energy use and efficiency improvements are becoming a key factor in evaluating solar suppliers.
