Significantly expanded the Company's participation in international ESG initiatives

Canadian Solar recently joined United Nations Global Compact (UNGC), committing to support and adhere to the Ten Principles of the UNGC on human rights, labor, environment, and anti-corruption. Canadian Solar has also recently submitted a commitment letter to the SBTi (Science Based Targets Initiative) indicating its intention to set near-term and net-zero science-based climate targets. In addition, the Company has completed CDP Climate Change 2023 Questionnaire, providing data on how climate-related issues are addressed in alignment with the TCFD recommendations.

On track to achieve the Company's environmental goals and targets.

2024, Canadian Solar lowered GHG emissions, energy, water, and waste intensities by 54%, 37%, 75%, and 53%, respectively, compared to 2017 levels. These achievements were driven by the enhanced production efficiency, implementation of robust energy and water conservation programs, as well as the increases in the power output of its solar modules. The Company also continues to align its operations with circular economy principles, increasing total recycled and reused waste to 94% in 2024 from 88% in 2023, while maintaining 100% recycling or reuse of packaging materials used during its production processes.

Ensuring ethical labor practices in the Company's operations and suppliers

In 2024, the Company conducted 147 supplier ESG audits and initiated a third-party assessment to evaluate the effective of its Anti-Modern Slavery Policy, Supplier Code of Conduct, and Human Rights Policy in preventing forced labor, among other initiatives. Specifically, the Company engaged the Responsible Business Alliance to conduct a Validated Assessment Program, covering areas of labor practices, health and safety, environment, ethics, and management systems.

Promoting diversity, inclusion, and equity

Canadian Solar is an equal-opportunity provider that strives to build a diverse workforce. For example, the Company has continued to prioritize providing employment opportunities for people with disabilities, hiring over 150 employees with disabilities as of 2024.

Advancing community engagement

Canadian Solar connects employees with its mission by organizing sustainability-related activities. This includes activities such as donations to orphanages and mountain clean-up activities. The Company also collaborates closely with stakeholders when it develops solar and battery storage projects and provides operation and maintenance services.

Protecting biodiversity

Canadian Solar prepares biological protection plans, takes measures, and obtains all required approval in terms of biodiversity protection for projects it develops and provides O&M services.
