ENSCO is Committed to Sustainability
As such, this report represents our first public disclosure of pertinent and relevant information. ENSCO has undertaken for the first time the calculation of our Scope 1 and 2 Greenhouse Gas (GHG) emissions for FY22, (July 1, 2021 – June 30, 2022) and hereby provides the results.

GHG Emissions, FY22 (7/1/2021 – 6/30/2022)

Scope Source FY22 Emissions (tCO2e)
1 Stationary Combustion of Fuel 580
1 Mobile Combustion, Fleets 106
1 Refrigerants 132
2 Purchased Electricity, location-based 1,497
2 Purchased Electricity, market-based 1,491
  Total Emissions, FY22 (tCO2e) 2,315

GHG Emissions Intensity Ratio

Total Scope 1 & 2 Emissions Per Employee (tCO2e/FTE) 3.3
Total Scope 1 & 2 Emissions Per Floor Area (tCO2e/sqft) 0.009

GHG Emissions Methodology

ENSCO has calculated Scope 1 and 2 emissions for the FY22 period using an operational control approach in accordance with the GHG Protocol.

  • Scope 1: Direct greenhouse gas emissions from sources owned or controlled by the company, such as emissions from gas, oil, and company vehicles.
  • Scope 2: Indirect greenhouse gas emissions from sources owned or controlled by the company, such as emissions from consumption of purchased electricity, heat, or steam.

Boundary Disclaimer: ENSCO’s Surface Transportation Group assumed operational management in October 2022 of the Transportation Technology Center (TTC), a 52-square-mile research, testing, and training facility owned by the Federal Rail Administration (FRA). Given ENSCO’s operation of the TTC site falls outside of the current FY22 reporting boundary for emissions, ENSCO will assess boundaries for inclusion into the FY23 GHG inventory and public disclosure.


Where data was not available, ENSCO utilized estimation methods in-line with the GHG Protocol, including use of proxy data, regional intensities and averages.


As new or more accurate information is made available to ENSCO, we plan to periodically recalculate our emissions, and will transparently restate as needed.

ENSCO Governance

Sustainability at ENSCO is overseen by a working group comprised of ENSCO’s Chief Financial Officer (CFO), Director of Contracts, and Director of Facilities. Each of these three positions report to ENSCO’s President, who meets with ENSCO’s Board of Directors quarterly. Sustainability updates are shared as needed and available through this hierarchy.
