Canadian Solar Releases 2025 Corporate Sustainability Report

KITCHENER, ON, June 1, 2026 /PRNewswire/ -- Canadian Solar Inc. (the "Company" or "Canadian Solar") (NASDAQ: CSIQ) today announced the publication of its 2025 Sustainability Report. The report outlines the Company's ongoing efforts in environmental stewardship, social responsibility, and corporate governance while supporting the global transition to clean energy.

The sustainability disclosures in this report are aligned with global standards established by the Sustainability Accounting Standards Board (SASB) and Global Reporting Initiative (GRI), with reference to the International Financial Reporting Standards (IFRS) set by the International Sustainability Standards Board (ISSB). The full report is available here.

The report provides a comprehensive overview of Canadian Solar's sustainability initiatives, including:

• Science-validated climate commitments: In December 2025, the Science Based Targets initiative validated the Company's near-term and long-term emissions reduction targets, including its commitment to net-zero greenhouse gas emissions across its value chain by 2050. With independent validation in place, Canadian Solar's climate commitments are anchored in science and subject to external accountability.
• Advancements in resource efficiency and circular economy: The Company implemented 59 energy conservation projects and 17 water-saving initiatives in 2025, delivering 101 GWh in energy savings and 1.46 million tons in water savings. Regarding its product carbon footprint, Canadian Solar's PV modules obtained Environmental Product Declaration (EPD) and ECS certification, while its SolBank 3.0 battery energy storage system successfully completed a life cycle assessment. Furthermore, two of the Company's manufacturing facilities earned Zero-Carbon Factory certification. These efforts, complemented by the global recycling of 6,909 end-of-life solar modules, underscore Canadian Solar's steadfast commitment to resource efficiency and circular economy principles throughout the product lifecycle.
• Deepening assurance across our operations and supply chain: In 2025, the Company assembled the most comprehensive body of independent evidence to date, reinforcing its commitment to upholding ethical labor practices across its operations and upstream supply chain. The Company's Suqian solar cell factory in China earned Silver-level recognition under the RBA Validated Assessment Program (VAP), joining its Thailand solar module factory which achieved the same rating in 2023. Additionally, its Suqian and Baotou factories in China completed Solar Stewardship Initiative assessments, receiving Silver and Bronze certifications, respectively. Beyond the Company's own factories, two of its key polysilicon suppliers in Qinghai Province, China completed RBA VAP audits at its request, each earning Silver-level recognition. All these audit results independently confirmed full compliance with Freely Chosen Employment standards.

Hanbing Zhang, Chief Sustainability Officer of Canadian Solar, commented, "We are pleased to present Canadian Solar's 2025 Sustainability Report, which reflects our global team's dedication to integrating sustainability into every facet of our operations. At Canadian Solar, we are committed to minimizing the environmental footprint of our operations, safeguarding the well-being of our employees, and maintaining a responsible supply chain. We believe transparency and accountability in our practices and reporting are essential to demonstrating our commitment to responsible business conduct and driving continuous improvement.

Colin Parkin, Chief Executive Officer of Canadian Solar, added, "The year 2025 was defined by significant progress in how we measure, manage, and improve the environmental and social performance of our business. We reached these milestones while navigating a challenging solar industry landscape, a backdrop that reinforced our decision to prioritize value-driven growth over volume. Underpinned by ethical business conduct, our commitment remains steadfast. We are not just delivering renewable energy solutions; we are ensuring that our manufacturing processes and supply chain operations are conducted with the highest standards of environmental stewardship and social responsibility to create lasting value for our stakeholders."
