The 2025 Sustainability Report of Canadian Solar outlines the company’s environmental, social, and governance (ESG) performance across its global operations in solar photovoltaic manufacturing, battery energy storage systems, and renewable energy project development.
As a major player in the clean energy industry, Canadian Solar continues to integrate sustainability into its core business strategy, focusing on decarbonization, resource efficiency, and long-term value creation. The report highlights measurable progress in emissions reduction, energy optimization, circular economy practices, and clean energy investments, supported by globally recognized ESG reporting standards such as GRI, SASB, and IFRS.
Net-Zero Emissions Commitment and Climate Strategy
Canadian Solar has committed to achieving net-zero greenhouse gas emissions across its entire value chain by 2050. This long-term climate goal has been validated by the Science Based Targets initiative (SBTi) in 2025, confirming that the company’s decarbonization pathway is aligned with global climate science.
To support this ambition, the company has established medium-term sustainability targets spanning 2024 to 2029. These targets focus on reducing greenhouse gas emissions intensity, energy consumption intensity, water usage intensity, and manufacturing waste intensity. The structured approach ensures that environmental performance improves consistently while the company continues expanding global production capacity and clean energy deployment.
Key Sustainability Achievements in 2025
In 2025, Canadian Solar achieved significant operational improvements across its global manufacturing network. The company implemented 59 energy conservation projects and 17 water-saving initiatives, resulting in substantial reductions in resource consumption. These initiatives delivered 101 GWh of electricity savings and 1.46 million tons of water savings, demonstrating the effectiveness of energy optimization systems and sustainable manufacturing practices.
The company also strengthened its circular economy initiatives by recycling 6,909 end-of-life solar modules globally. This effort reduces waste generation and supports material recovery for reuse in manufacturing processes, contributing to a more sustainable solar product lifecycle.
In addition, Canadian Solar enhanced product-level environmental transparency by completing Environmental Product Declarations (EPDs) for photovoltaic modules and conducting a full Life Cycle Assessment (LCA) for its SolBank 3.0 energy storage system. These assessments provide detailed environmental impact data across the entire product lifecycle, from raw material sourcing to end-of-life disposal.
ESG Compliance and Supply Chain Responsibility
A key pillar of Canadian Solar’s sustainability strategy is strengthening supply chain transparency and ensuring compliance with global labor and environmental standards. The company conducted third-party audits across key manufacturing facilities and upstream suppliers to verify adherence to responsible sourcing and ethical production practices.
Several facilities achieved certifications under internationally recognized frameworks such as the Responsible Business Alliance Validated Assessment Program (RBA VAP) and the Solar Stewardship Initiative (SSI). These certifications confirm compliance with strict requirements related to labor rights, workplace safety, environmental management, and ethical sourcing. The Suqian solar cell factory achieved an RBA Silver rating, while the Thailand module facility maintained Silver status. Two upstream polysilicon suppliers in Qinghai also achieved RBA Silver ratings, and manufacturing sites in Suqian and Baotou received SSI Silver and Bronze certifications respectively.
Energy Efficiency and Operational Performance Improvements
Canadian Solar continues to improve energy efficiency through advanced management systems and internationally certified operational frameworks. The company operates under ISO 14001, ISO 45001, and ISO 50001 standards, ensuring structured management of environmental impact, occupational health and safety, and energy efficiency across global facilities.
Over time, the company has achieved significant reductions in environmental intensity metrics. Between 2017 and 2024, Canadian Solar reduced greenhouse gas emissions intensity by 54 percent, energy consumption intensity by 37 percent, water usage intensity by 75 percent, and waste generation intensity by 53 percent. These improvements reflect continuous investment in cleaner production technologies, process optimization, and energy-efficient manufacturing systems.
Circular Economy and Resource Optimization Strategy
Circular economy principles are central to Canadian Solar’s sustainability approach. The company has significantly increased recycling and reuse rates across its operations, achieving a 94 percent waste recycling and reuse rate in 2025, up from 88 percent in the previous year. Packaging materials reached 100 percent recycling or reuse compliance, supporting zero-waste manufacturing goals.
These initiatives reduce dependency on virgin raw materials, improve resource efficiency, and minimize environmental impact across the production lifecycle. By integrating circular economy principles, Canadian Solar is enhancing sustainability performance while improving operational cost efficiency and material recovery systems.
Clean Energy Investment and Business Expansion Strategy
Canadian Solar is significantly expanding its investment in renewable energy generation and battery energy storage systems. Through its e-STORAGE business unit, the company has shipped over 20 GWh of battery energy storage systems globally and developed a contracted project backlog valued at approximately 3.5 billion dollars as of 2026.
The company also maintains a large-scale development pipeline comprising 24 GWp of solar capacity and 81 GWh of energy storage projects. This expansion reflects its strategic transition from a solar module manufacturer into a fully integrated clean energy solutions provider with capabilities spanning solar generation, storage, and project development.
These investments strengthen Canadian Solar’s position in global energy markets and support the increasing demand for grid stability, renewable integration, and energy security solutions.
ESG Governance and Reporting Framework
Canadian Solar maintains strong ESG governance through a dedicated board-level sustainability committee responsible for overseeing environmental and social performance. This governance structure ensures that sustainability considerations are embedded in corporate strategy, risk management, and investment decisions.
The company aligns its sustainability reporting with globally recognized frameworks, including the Global Reporting Initiative (GRI), Sustainability Accounting Standards Board (SASB), and IFRS Sustainability Disclosure Standards. This alignment enhances transparency, comparability, and accountability of ESG performance across global operations.
Conclusion
The Canadian Solar 2025 Sustainability Report demonstrates strong progress in emissions reduction, energy efficiency, circular economy development, and responsible supply chain management. With validated net-zero targets, measurable resource savings, and continued expansion in solar and energy storage investments, the company is reinforcing its leadership in the global clean energy transition.
Through integrated ESG governance, technological innovation, and large-scale clean energy deployment, Canadian Solar is positioning itself for long-term sustainable growth while contributing meaningfully to global decarbonization efforts and the transition to a low-carbon energy future.
