Data Center
CenterPoint Energy’s Data Center reflects our transparency by regularly reporting our sustainability performance data in a central location. The Data Center informs our stakeholders of our progress on issues that we believe are most relevant for our business and identifies areas for continuous improvement.
Our voluntary reporting is also mapped to commonly used frameworks, including the Global Reporting Initiative (GRI) Index, Sustainability Accounting Standards Board (SASB) standards, and the Edison Electric Institute (EEI) and the American Gas Association (AGA) ESG/sustainability reporting template.
We also voluntarily published our first Task Force on Climate-related Financial Disclosures Report in 2022 to enhance the disclosures around the progress of our energy transition.
