In 2025, CSI Solar reported Scope 2 greenhouse gas (GHG) emissions of 839,946 tCO₂e using the market-based method and 988,320 tCO₂e using the location-based method.a
Compared to the previous year (2024), CSI Solar's Scope 2 emissions (Location-Based) fell by 45.04% in 2025, showing that the company has made progress in taking action to reduce the climate impact of its energy consumption.a
In 2025, CSI Solar reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, CSI Solar reported 19,855,829 metric tons of CO₂ equivalent (tCO₂e) of Scope 3 greenhouse gas (GHG) emissions, representing indirect emissions across its upstream and downstream value chain.a
The 2025 disclosure of CSI Solar includes a breakdown across 10 of the 15 Scope 3 categories defined by the GHG Protocol, matching the level of disclosure in 2024, demonstrating consistent Scope 3 emissions reporting coverage year over year.a
In 2025, CSI Solar reported total Scope 3 emissions of 19,855,829 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 97.67% of these emissions originated from upstream activities such as purchased goods and capital goods, while 2.33% came from downstream activities like product use, distribution, and end-of-life treatment.a
Compared to the previous year (2024), CSI Solar's Scope 3 emissions decreased by 26.94%, highlighting the company's efforts to lower indirect emissions from its value chain.a
In 2025, CSI Solar reported emissions for 10 out of the 15 Scope 3 categories defined by the GHG Protocol.a
This reflects a high level of granularity and transparency in the company's emissions reporting.
In 2025, the largest contributors to CSI Solar's Scope 3 emissions were:a
In 2025, CSI Solar reported Scope 1 greenhouse gas (GHG) emissions of 71,221 tCO₂e and total revenues of USD 5,750 millions. This translates into an emissions intensity of 12.39 tCO₂e per millions USD.a
In 2025, CSI Solar reported a Scope 1 emissions intensity of 12.39 tCO₂e per millions USD. Compared to the peer group median of 7.53, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, CSI Solar ranked 16 out of 24 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
CSI Solar is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, CSI Solar reported a total carbon footprint of 20,915,370 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 27.91% decrease compared to 2024, indicating progress in reducing its overall greenhouse gas output.a
The largest contributor to CSI Solar's total carbon footprint was Scope 3 emissions, accounting for 94.93% of the company's total carbon footprint, followed by Scope 2 emissions at 4.73%.a
