In 2024, Sempra completed a corporate carbon footprint assessment and publicly disclosed its greenhouse gas (GHG) emissions according to the GHG Protocol, covering Scope 1 (direct emissions from owned or controlled sources), Scope 2 (indirect emissions from purchased energy) and Scope 3 (indirect emissions across the value chain).
However, Sempra has not published a category-level breakdown of its Scope 3 emissions, limiting visibility into specific value chain sources.

Compared to the previous year (2023), Sempra's Scope 2 emissions (Unspecified Calculation Method) have remained relatively stable, indicating that Sempra's emissions have plateaued with no significant change in its energy consumption footprint.a
In 2024, Sempra reported its Scope 2 emissions using an unspecified methodology.a
In 2024, Sempra reported 66,000,000 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 2024 disclosure of Sempra includes a breakdown across 0 of the 15 Scope 3 categories defined by the GHG Protocol, matching the level of disclosure in 2023, demonstrating consistent Scope 3 emissions reporting coverage year over year.a
In 2024, Sempra reported total Scope 3 emissions of 66,000,000 metric tons of CO₂ equivalent (tCO₂e).a
Since 2019, Sempra's Scope 3 emissionshave remained relatively stable, indicating that Sempra's emissions have plateaued with no significant change in its value chain footprint.ac
Compared to the previous year (2023), Sempra's Scope 3 emissions remained relatively stable, indicating that Sempra's emissions have plateaued with no significant change in its value chain footprint.a
In 2024, Sempra reported Scope 1 greenhouse gas (GHG) emissions of 6,700,000 tCO₂e and total revenues of USD 13,185 millions. This translates into an emissions intensity of 508.15 tCO₂e per millions USD.a
In 2024, Sempra reported a Scope 1 emissions intensity of 508.15 tCO₂e per millions USD. Compared to the peer group median of 563.7, this places the company below its industry benchmark, indicating it is more carbon-efficient than most competitors.a
In 2024, Sempra ranked 13 out of 24 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Sempra is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2024, Sempra reported a total carbon footprint of 73,258,000 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 2.48% decrease compared to 2023, indicating progress in reducing its overall greenhouse gas output.a
The largest contributor to Sempra's total carbon footprint was Scope 3 emissions, accounting for 90.09% of the company's total carbon footprint, followed by Scope 1 emissions at 9.15%.a
