Energy use has historically been reported net of solar energy produced within the portfolio and in megawatt-hours in previous company disclosures. In this report, the company presents gross energy consumption at locations (prior to solar energy offset), and presents the data in Gigajoules to comply with the SASB framework. The Company also presents consumption in mega-watt hours since it is the preferred reporting metric by certain stakeholders.
Water use has historically been reported in kilogallons in previous company disclosures. In this report, the company also presents water withdrawal in Thousand Cubic Meters to comply with the SASB framework.
