Innovative products
For Innovative Products, the company allocated 5.96% of its revenue to R&D in 2023, an 8% year-over-year increase over 2022. Wong also noted that LONGi has invested in intelligent manufacturing at its Jiaxing factory, recognized as a global lighthouse factory by the World Economic Forum. Additionally, Wong emphasized that the low-carbon products produced at these factories must be certified by France, Korea, or Italy. The company follows the EPD (Environmental Product Declaration) framework, which provides end-to-end lifecycle carbon footprint certification.
Green climate action
Regarding its environmental initiatives, LONGi is investing in reducing Scope 1, Scope 2 (within its control), and Scope 3 greenhouse gas emissions. The company aims to achieve the RE100 target of 100% renewable energy (RE) usage by 2028, with intermediate targets of 70% by 2027 and 100% by 2028. Wong stated that LONGi's near-term Scope 1, Scope 2, and Scope 3 targets have been validated by the Science Based Targets Initiative (SBTi). This commitment includes reducing absolute Scope 1 and 2 GHG emissions by 60% and reducing Scope 3 emissions from purchased goods and services by 52% per tonne of purchased materials by 2030, both from the 2020 base year. In alignment with the RE100 initiative, the company's operations are currently powered by 47.8% renewable energy, with 2.1% generated from captive solar and the remaining 97.86% sourced from the power trading market, noted Wong.
Harmony & trustworthiness
From the perspective of people and community, the social aspect of ESG, and meeting customer expectations for protecting labor rights and maintaining an ethical workplace, LONGi believes it has an advantage as a vertically integrated company, spanning from polysilicon to modules. Wong noted that LONGi's single business code of conduct, designed to ensure compliance across its vertically integrated supply chain, is in line with international business practices, including the United Nations Global Compact (UNGC), the International Labour Organization (ILO), and OECD guidelines. Additionally, the consistent implementation of these business code of conducts has been periodically validated through 3rd-party certifications, such as the ISO 26000 Social Responsibility Assessment. In addition to ISO 26000, LONGi has also earned the SA8000 Social Accountability Certification.
Supply chain
Regarding the sustainable supply chain, Wong explained that 100% of the company’s suppliers have signed the Supplier Code of Conduct, and all new suppliers meet social and environmental standards, which is in line with UNGP, ILO, and OECD guidelines. As part of the company's 2024-2028 supplier roadmap, significant suppliers currently account for 55% of total procurement expenditure. However, this figure is expected to rise to 80% by 2028. LONGi follows a 3-step risk monitoring process for its suppliers, says Wong.
