Environmental Footprint

Greenhouse Gas (GHG) Emissions

DNOW measures and reports Scope 1 and Scope 2 greenhouse gas emissions in accordance with the GHG Protocol. Both are reported in metric tons of carbon dioxide equivalent (MT CO2e). The MRC Global acquisition significantly expanded DNOW’s operational footprint.

Global GHG Emissions (MT CO2e) 2025
Scope 1 (equipment, vehicle fuel & natural gas) 32,526
Scope 2 (electricity & district heating) 12,191
Total Scope 1 & 2 (location-based) 44,716
Total Scope 1 & 2 (market-based)1 46,205
Emissions intensity (MT CO2e / $M revenue)2 8.5

1 Scope 2 (market-based) emissions are 13,679 MT CO2e. See Environmental data table on page 57.
2 Scope 1 + 2 (location-based) emissions divided by unaudited pro forma combined revenue of $5,274 million for the year ended December 31, 2025, as disclosed in the Company’s 2025 Form 10-K. Not comparable to intensity figures reported by either predecessor company. Due to rounding, amounts may not sum to totals presented.

Energy, Water & Waste

Facility energy consumption is a major component of DNOW’s operational footprint, alongside fuel consumed by the Company’s fleet. Energy data is compiled from natural gas and electricity utility bills across global operations, with most facilities sourcing power from local providers.

Facility Energy by Source (GJ)  2025
Natural Gas 142,639
Purchased electricity 126,172
District heating 1,850
On-site solar (consumed on-site) 654
Other heating fuels 910
Total facility energy 272,224

Fleet and Fuel Efficiency

DNOW’s vehicle fleet is the Company’s largest source of direct emissions, accounting for nearly 80% of Scope 1 emissions and 57% of combined Scope 1 and 2 emissions. Route optimization, fleet efficiency initiatives and freight consolidation help reduce transportation impacts across the network.

In 2025, 449.5 MT CO₂e of DNOW parcel-shipment1 emissions were offset through the UPS Carbon Neutral program.2

Fleet Fuel Combustion3 2025
Total fleet fuel consumption (GJ) 392,070
Total fleet GHG emissions (MT CO₂e) 25,305
On-road share of fleet fuel (%) 97%
Non-road equipment fuel share (%) 3%
Renewable share of fleet fuel (%) 0.1%

1 Parcels are typically smaller and lighter than bulk freight shipments, with a maximum weight limit of 150 pounds per package.
2 The UPS Carbon Neutral program is certified to CarbonNeutral® Protocol standards. Emissions for enrolled shipments are calculated by UPS and verified by SGS.
3 Fleet includes on-road vehicles and fuel-powered non-road equipment, including propane-fueled forklifts; excludes natural gas combusted at facilities.

Products with Purpose

Emissions Mitigation & Containment

DNOW supplies products that help customers reduce fugitive emissions, which represent both compliance exposure and lost product for operators. Pipe, valves and fittings (PVF) are the core components of industrial fluid and gas systems, and their performance directly determines how well emissions are managed at the facility level.

Reducing Customer Emissions

Low-Emission (Low-E) Valves

Cast and forged valve lines certified to limit fugitive emissions under API 624/641 and ISO 15848-1

Sealless Magnetic Drive Centrifugal Pumps

Eliminate mechanical seal leak points, a primary source of fugitive emissions in fluid handling

High-Performance Spiral Wound Gaskets

Reduce fugitive emissions at pipe connection points

Containment Systems

Reduce leak potential and capture contaminants before release

Lower Manufacturing Footprint

API 5L Steel Pipe

Produced from recycled steel scrap using electric arc furnace technology rather than traditional blast furnace processes

Forged Steel Fittings, Flanges and Bolts

Produced from recycled steel sources

Glass Reinforced Epoxy Piping Systems

Produced with less energy than carbon steel pipe, with additional transport emissions savings from lighter weight

Renewably Produced Pipe

Select pipe product lines produced using wind power, recycled water and wood pellet inputs

Fueling Our Environmental Inventory

PRODUCT SPOTLIGHT

EcoVapor DryOxo™

Oxygen Removal & Gas Drying Systems

In 2025, EcoVapor launched the DryOxo™ line, which eliminates oxygen and removes moisture from natural gas streams in a single process. This purification allows gas to meet strict pipeline specifications so it can be sold rather than vented or flared. A single DryOxo ET2000 unit is designed to enable operators to reduce up to 100,000 MT CO2e annually.1
