In 2025, the total Scope 1 emissions of Synopsys were 3,616 metric tons of CO₂ equivalent (tCO₂e).a
Since 2019, Synopsys's Scope 1 emissions have decreased by 3.44%, reflecting a declining long-term trend in Scope 1 emissions over time.ab
Compared to the previous year (2024), Synopsys's Scope 1 emissions increased by 59.08%, suggesting that the company faced challenges in reducing emissions from its directly owned or controlled operations.ab
In 2025, Synopsys reported Scope 2 greenhouse gas (GHG) emissions of 30,293 tCO₂e using the market-based method and 52,656 tCO₂e using the location-based method.a
Since 2019, Synopsys's Scope 2 greenhouse gas (GHG) emissions (Location-Based) have increased by 49.91%, reflecting a rising long-term trend in Scope 2 emissions over time.ab
Compared to the previous year (2024), Synopsys's Scope 2 emissions (Location-Based) have remained relatively stable, indicating that Synopsys's emissions have plateaued with no significant change in its energy consumption footprint.ab
In 2025, Synopsys reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, Synopsys reported 311,285 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 Synopsys includes a breakdown across 12 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, Synopsys reported total Scope 3 emissions of 311,285 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 82.89% of these emissions originated from upstream activities such as purchased goods and capital goods, while 17.11% came from downstream activities like product use, distribution, and end-of-life treatment.a
Since 2019, Synopsys's Scope 3 emissions have increased by 51.32%, reflecting a rising long-term trend in Scope 3 emissions over time.ab
Compared to the previous year (2024), Synopsys's Scope 3 emissions increased by 40.76%, suggesting that the company faced challenges in reducing emissions across its value chain.ac
In 2025, Synopsys reported emissions for 12 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 Synopsys's Scope 3 emissions were:a
In 2025, Synopsys reported Scope 1 greenhouse gas (GHG) emissions of 3,616 tCO₂e and total revenues of USD 7,054 millions. This translates into an emissions intensity of 0.51 tCO₂e per millions USD.a
In 2025, Synopsys reported a Scope 1 emissions intensity of 0.51 tCO₂e per millions USD. Compared to the peer group median of 0.18, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, Synopsys ranked 21 out of 24 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
This places Synopsys among the least efficient performers, with one of the highest emissions intensities in its sector.a
In 2025, Synopsys reported a total carbon footprint of 367,557 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 33.84% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.abc
The largest contributor to Synopsys's total carbon footprint was Scope 3 emissions, accounting for 84.69% of the company's total carbon footprint, followed by Scope 2 emissions at 14.33%.a
