REPORTING & DISCLOSURE TRACKING OUR PROGRESS DOW | REPORTING & DISCLOSURE | 126 Dow Disclosures – GRI Content Index 302-1 Energy consumption within the organization Energy Consumption In 2021, the methodology used to calculate energy consumption was updated to align with industry best practices which includes: 1) adjusting the reported purchased fuels value to exclude fuels resold externally or used internally as feedstocks, and 2) using off-gas from feedstock to include non-cracker sources, and 3) calculating power and steam sold and purchased steam using the work potential method versus the energy content method used in prior years. For Purchased Fuels and off-gas from Feedstock the changes are being applied prospectively; prior year periods will not be revised. To enable comparisons to prior year data, the 2021 values have also been calculated and provided below using the historical method. See disclosures 302-4 Reduction of energy consumption and 305-2 Energy indirect (Scope 2) GHG emissions for actions to reduce energy consumption. Overall, total energy consumption for 2021 was flat when compared to 2020.

Previous reporting utilized the energy content method. Prior year values have been updated in this report to reflect the work potential method.
