About Royal Gold Governance Our People Our Operators and Communities ESG Stewardship Appendices 82 2023 INVESTMENT STEWARDSHIP REPORT ROYAL GOLD Operator energy consumption The following table presents estimates for direct and indirect energy usage, which can be attributed to our interests, for a majority of our revenue-generating mineral properties, as available from Skarn Associates, an independent ESG data analytics firm, for calendar years 2018 through 2022. The table also details the GHG emissions associated with each unit of direct and indirect energy and provides a weighted average performance for the portfolio. Entries labelled “NR” means the data were not reported in the Skarn Associates database and those labelled “–” are for periods when Royal Gold did not have royalty or stream revenue from the mineral property. Skarn Associates may update prior year information, which we may have presented in prior reports. We use the most current data available from Skarn Associates and adjust our presentation of data and calculations accordingly.
