ENSCO Sustainability Report

ENSCO is Committed to Sustainability
This report represents our second public disclosure of pertinent and relevant information. ENSCO has undertaken the calculation of our Scope 1 and 2 Greenhouse Gas (GHG) emissions for FY23, (July 1, 2022 – June 30, 2023) and hereby provides the results.

GHG Emissions, FY22 and FY23 (7/1/2021 – 6/30/2023)

Scope	Source	FY22 Emissions (tCO2e)	FY23 Emissions (tCO2e)
1	Stationary Combustion of Fuel	109	163.5
1	Mobile Combustion, Fleets	106	236
1	Refrigerants	132	127
2	Purchased Electricity, location-based	1,497	1,567
2	Purchased Electricity, market-based	1,491	1,605
	Total Emissions (location-based)(tCO2e)	1,844	2,094

NB: ENSCO has made improvements to the calculation methodology and process in our second year of reporting. As such, ENSCO is voluntarily restating the FY22 stationary combustion of fuel emissions from the originally reported value in our 2022 report which is a more accurate representation of our emissions.

GHG Emissions Intensity Ratio

	FY22	FY23
Total Scope 1 & 2 Emissions Per Employee (tCO2e/FTE)	2.6	2.8
Total Scope 1 & 2 Emissions Per Floor Area (tCO2e/sqft)	0.007	0.008

GHG Emissions Methodology

ENSCO has calculated Scope 1 and 2 emissions 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). The TTC site is not currently included in our emissions reporting.

Estimations

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

Restatements

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), Vice President for Procurement, 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.
