Milestone’s Net Carbon Benefit
Milestone’s Net Carbon Benefit
Our business prevents hydrocarbons contained in our customers’ waste from volatilizing or otherwise degrading into fugitive emissions, and instead permanently sequesters them beneath the Earth’s surface. If these waste streams had been disposed of through common practices such as land application (i.e., reserve pits), resulting fugitive emissions would otherwise occur naturally over time. Milestone has the largest slurry injection installed capacity based in the U.S. The net carbon benefit of the avoided emissions from our waste sequestration technology far outpaces our operating emissions.
The table below details our total emissions for the year ended December 31, 2022.
6 Total Avoided Emissions based on the avoided CO2 emissions from degradation of hydrocarbons that would have occurred if E&P waste was disposed of via landfarming.
7 Our landfill emissions were calculated by a third-party engineering firm registered within the State of Texas. These volumes were calculated using equations and programs approved by the U.S. Environmental Protection Agency (EPA) and Texas Commission on Environmental Quality (TCEQ) to support Milestone’s air permit applications. Scope 1 emissions resulting from our landfills amounted to 66.14 MT CO2e during 2022.
8 Scope 1 emissions resulting from company-owned vehicles amounted to 2,259 MT CO2e during 2022. Milestone does not maintain a vehicle fleet commonly associated with waste management companies. Company-owned vehicles include diesel-fueled pickup trucks and other off-road equipment.
9 During 2022, all electricity consumed in our operations originated from the Electric Reliability Council of Texas (ERCOT) grid.
