Sustainability Accounting Standards Board (SASB)
CenterPoint Energy 2021 Sustainability Accounting Standards Board (SASB) Table
The Sustainability Accounting Standards Board (SASB) has established voluntary industry-specific disclosure standards across environmental, social and governance (ESG) topics that facilitate communication between companies and investors in order to simplify company-to-company comparisons.
These tables mark CenterPoint Energy’s second year of annual mapping our disclosures to the SASB Standards for the Infrastructure Sectors of Electric Utilities & Power Generators and Gas Utilities & Distributors. Our response reflects year-end 2021 performance for topics that we have identified as key issues.
As we continue to assess our ESG data, we may choose to include additional SASB metrics in future reports. Unless otherwise stated, data relates only to the sector of our business indicated in the chart headings. Previous reports can be found in the CenterPoint Energy Report Archives, which are located in our ESG Data Center.
