Our Reporting Framework


The specific metrics in our 2021 Sustainability Report were determined by assessing the most relevant and impactful performance areas for Milestone, our investors, and other key stakeholders. This report follows the guidance of the Sustainability Accounting Standards Board(SASB) of the Value Reporting Foundation. SASB standards provide an accepted reporting framework that yields decision-useful metrics, helps us track progress, and enables comparability for our investors and other stakeholders. Milestone is an energy waste management company that is classified within the Waste Management industry according to SASB’s Sustainable Industry Classification System®. Given the current nature of our customer base and operations, we also considered relevant disclosures suggested for the Oil & Gas Services industry.

When evaluating our disclosures in relation to SASB standards, users in some cases will need to normalize the data to make meaningful comparisons. As such, we have included certain activity metrics to aid users in their evaluation. Refer to our SASB Index, which highlights our responses to suggested SASB accounting metrics and includes the appropriate activity metrics to assess our disclosed data in a meaningful context. The information provided within this report is as of and for the years ended December 31, 2021 and 2020, unless otherwise noted.
