Announcement event for the "Climate Change Mitigation White Paper" and the first "TNFD Report" at COP30.

LONGi announced the "Climate Change Mitigation White Paper" and the first "TNFD Report" at COP30.

  • Company news

LONGi, a company that globally deploys solar power generation technology, announced the "2024-2025 Climate Change Mitigation White Paper" and its first TNFD (Taskforce on Nature-related Financial Disclosures) report at COP30 (the 30th United Nations Climate Change Conference of the Parties) held in Belém, Brazil. This white paper organizes efforts for decarbonization and medium- to long-term strategies across the entire value chain, from research and development to manufacturing, logistics, and product use. LONGi has set a medium-term goal of reducing Scope 1 and 2 emissions by 60% compared to 2020 levels and reducing Scope 3 emissions per unit by 52% by 2030, positioning the achievement of net zero by 2050 as a long-term goal. Additionally, the TNFD report, which is being published for the first time, analyzes the relationship with natural capital such as forests, water resources, and biodiversity based on the LEAP approach. It clearly states its commitment to reflecting nature-related risks and opportunities in management strategies and governance. LONGi aims to continue balancing climate change measures and nature conservation, contributing to the realization of a sustainable energy society.
