Accounting Metrics
Emissions
Greenhouse Gas Emissions EM-MD-110a.1 Gross global Scope 1 emissions, percentage methane, percentage covered under emissionslimiting regulations Carbon Management; Performance Data
EM-MD-110a.2 Discussion of long-term and short-term strategy or plan to manage Scope 1 emissions, emissions reduction targets and an analysis of performance against those targets Carbon Management
Environmental Management
Air Quality EM-MD-120a.1 Air emissions of the following pollutants: (1) NOx (excluding N2O), (2) SOx, (3) volatile organic compounds (VOCs) and (4) particulate matter (PM10) Environmental Management; Performance Data
Biodiversity and Land Use
Ecological Impacts EM-MD-160a.1 Description of environmental management policies and practices for active operations Environmental Management
EM-MD-160a.2 Percentage of land owned, leased and/or operated within areas of protected conservation status or endangered species habitat Performance Data
EM-MD-160a.3 Terrestrial acreage disturbed, percentage of impacted area restored At this time, Crestwood does not collect this data. We will assess collecting this for future reporting years.
Government Relations and Regulatory Compliance
Competitive Behavior EM-MD-520a.1 Total amount of monetary losses as a result of legal proceedings associated with federal pipeline and storage regulations Performance Data
Spill Prevention Control and Emergency Response
Ecological Impacts EM-MD-160a.4 Number and aggregate volume of hydrocarbon spills, volume in Arctic, volume in Unusually Sensitive Areas (USAs) and volume recovered Performance Data
Operational Safety, Emergency Preparedness & Response EM-MD-540a.1 Number of reportable pipeline incidents, percentage significant Performance Data
EM-MD-540a.3 Number of (1) accident releases and (2) nonaccident releases (NARs) from rail transportation Performance Data
EM-MD-540a.4 Discussion of management systems used to integrate a culture of safety and emergency preparedness throughout the value chain and throughout project lifecycles Prioritizing Safety
Asset Integrity
Operational Safety, Emergency Preparedness & Response EM-MD-540a.2 Percentage of (1) natural gas and (2) hazardous liquid pipelines inspected Performance Data
Activity Metric
Economic Performance EM-MD-000.A Total metric ton-kilometers of: (1) natural gas, (2) crude oil and (3) refined petroleum products transported, by mode of transport This metric was omitted based on the lack of applicability. Instead, Crestwood reports our greenhouse gas emissions intensity as a function of EBITDA (metric tons CO2e/$MM Adjusted EBITDA) and methane intensity metric in accordance with ONE Future guidance. We believe that these metrics provide the most information about the impacts of our operations and comparability for our stakeholders.
