Company achieves 37% reduction of fugitive methane emissions in 2021
Los Angeles, CA /PRNewswire/ - Southern California Gas Co. (SoCalGas) has submitted its annual fugitive emissions report to the California Public Utilities Commission (CPUC). The report shows that SoCalGas has significantly exceeded the state's 2025 goal for reducing fugitive methane emissions. SoCalGas reported that in 2021 it reduced fugitive methane emissions by 37% – passing the state's goal of a 20% reduction by 2025 and nearing the state's goal of a 40% reduction by 2030.
The company's success comes from significant innovation in new detection technologies. SoCalGas was the first utility in the nation to implement aerial methane mapping using helicopter-mounted LiDAR technology to detect leaks. The company also has begun using drones – including first-of-its-kind hydrogen-powered drone technology – to map and detect methane.
"It is a testament to our dedicated workforce that we have not only exceeded 2025 reduction goals, but also are quickly approaching 2030 goals as we continue to build the cleanest, safest and most innovative energy company in America," said Jimmie Cho, SoCalGas Chief Operating Officer.
Percentage calculations are based upon a 2015 emissions baseline. Utilities' progress toward state goals are tracked and reported via CPUC-mandated annual reports.
SoCalGas has made meaningful strides to reduce methane emissions since 2015, in addition to investments in leak detection technology.
- Accelerated leak repairs relating to our aerial methane mapping program reduced methane emissions equivalent to avoiding 1,031 metric tons of carbon dioxide equivalent emitted and incrementally increased the ability of detecting and repairing leaks faster
- SoCalGas accelerated its leak survey cycles from every three years to every year for certain types of pipe, leading to more prompt leak repairs further reducing methane emissions
- A 94% reduction in gas venting during maintenance or repairs when compared to 2015, which is equivalent to avoiding 39,432 metric tons of carbon dioxide equivalent emitted
- A 92% reduction in emissions from SoCalGas storage facilities since 2015 due to upgrades in compressor and venting equipment
Last year, SoCalGas announced its aspiration to achieve net zero greenhouse gas emissions in its operations and the energy it delivers by 2045 and earlier this year released its ASPIRE 2045 Sustainability Strategy to help reach that goal.
