In 2025, Sempra generated a total of 216,196metric tonnes of waste.a
Of this amount, 37.96% of Sempra's total waste generated was recovered through methods such as recycling, reuse, or composting, while 62.04% was disposed of through landfilling, incineration, or combustion.a
In 2025, Sempra reported a total waste generation of 216,196 metric tonnes, of which 37.96% was recovered through recycling, reuse, or composting.This moderate level of recovery indicates that Sempra is taking steps toward improving its waste diversion practices, though there is still room to enhance recycling and recovery efforts.a
Since 2022, Sempra's total waste generation increased by 92.19%, including a 30.66%increase in 2025, indicating a persistent upward trend that may reflect scaling operations, inefficiencies in resource use, or a lack of effective waste minimization practices.a
Over the same period, Sempra's waste recovery rate declined by 4.67%, yet improved by 16.04% in 2025, pointing to a recent rebound or renewed focus on better waste treatment outcomes.a
Overall, Sempra’s waste generation and recovery data show a mixed and inconsistent trend. A deeper analysis of the company's activities, industry benchmarks, and operational changes is needed to assess its sustainability performance more precisely.
In 2025, Sempra generated a total of 216,196 metric tonnes of waste.a
Of this amount, 2.77% of Sempra's total waste generated of was classified as hazardous waste, characterized by properties such as toxicity, flammability, corrosiveness, or reactivity that may pose risks to human health, ecosystems, or the environment.97.23% was identified as non-hazardous waste, generally considered less harmful and subject to lighter regulatory controls.a
Since 2022, Sempra's total waste generation increased by 92.19%, including a 30.66% rise in 2025, reflecting a persistent upward trend that could be linked to operational growth, inefficient material use, or limited investment in waste prevention systems.a
Over the same period, Sempra reduced the hazardousness of its waste by 43.09%, with a further 27.78% decline in 2025, suggesting a sustained and meaningful shift toward safer waste profiles and lower environmental impact.a
Overall, Sempra is generating more waste but has significantly reduced the share of hazardous materials, suggesting a partial decoupling of volume and toxicity that could reflect more responsible inputs or enhanced treatment.a
In 2025, Sempra reported that 5,989 metric tonnes of its total waste output were classified as hazardous. This represents 2.77% of its overall waste generation.a
The company treated this hazardous waste using a combination of methods.Approximately 13.44% was managed through recovery methods, indicating a moderate integration of circular practices into its hazardous waste management. However, a significant share was still directed toward disposal, highlighting room for improvement in reducing the long-term impact of hazardous materials.a
