Scope 1
Scope 2
Scope 3
Emissions that a company causes indirectly when the energy it purchases and uses is produced – e.g., the emissions from the generation of electricity used to power our electric fleet of vehicles
Scope 2
Emissions from sources a firm owns or controls directly – e.g., burning fuel in our fleet of vehicles
Scope 1
GHG emissions that are not produced directly by a company’s activities, but occur along the company’s value chain - e.g., airplane emissions from Langan’s business travel
Scope 3
Firm Initiatives
Langan has maintained carbon-neutral scope 1 and scope 2 emissions since 2018 as part of our ongoing efforts to understand and manage the greenhouse gas (GHG) emissions associated with our operations.
We measure our GHG emissions annually in alignment with the World Resources Institute Greenhouse Gas Protocol. Through 2024, we reported full scope 1 and scope 2 emissions, as well as scope 3 emissions from business travel. In 2025, we expanded our scope 3 GHG inventory to include the following value-chain emissions categories relevant to our operations: purchased goods and services, capital goods, upstream fuel- and energy-related activities, upstream transportation and distribution, waste generated in operations, business travel, employee commuting, and upstream leased assets. We also expanded the methodology for business travel emissions to cover lodging and meals. As we continue to improve data collection and methodology for capturing our scope 3 emissions, we may refine these results over time.
As Langan’s business continues to grow domestically and internationally, our absolute scope 1 and scope 2 GHG emissions have generally increased alongside our geographic footprint and business activity. To better understand our environmental impact in the context of this growth, Langan tracks scope 1 and market-based scope 2 GHG emissions on an intensity basis relative to annual revenue. We report carbon intensity in metric tons of carbon dioxide equivalent per million dollars in revenue (tCO2e/$MM).
Langan’s scope 1 and market-based scope 2 carbon intensity decreased from 4.0 tCO2e/$MM in 2024 to 3.3 tCO2e/$MM in 2025, an approximately 18% decrease. Since our calculation of 5.8 tCO2e/$MM in 2019, our baseline year, our carbon intensity has declined by approximately 44%.
We continue to manage our carbon footprint by implementing green office operations. These include locating new Langan offices in LEED-certified buildings or buildings that meet other energy-efficiency standards, transitioning our fleet to electric and hybrid vehicles, and making informed decisions about business travel. As we implement measures intended to manage our GHG emissions, we have partnered with ClimeCo to offset our remaining scope 1 and scope 2 GHG emissions and maintain carbon neutrality for these categories.
As part of our commitment to environmental responsibility and transparency, Langan discloses our GHG emissions and management of our carbon footprint. Presently, we do not engage an independent third party to verify our GHG emissions inventory, and we have not yet established formal GHG reduction targets. We understand the importance of assessing and mitigating our environmental impact and are actively exploring options to develop a comprehensive GHG emissions management plan, including third-party verification and establishing formal GHG reduction targets.

CARBON FOOTPRINT
Carbon Offsetting
Since 2018, Langan has partnered with a carbon offset program led by ClimeCo (formerly administered by Carbonfund.org Foundation) to address our residual scope 1 and scope 2 GHG emissions through the purchase and retirement of verified carbon offsets.
From 2023 through 2025, the offsets purchased and retired by Langan through ClimeCo were issued by a nitrous oxide abatement project registered with the Climate Action Reserve (CAR). The project reduces nitrous oxide emissions associated with adipic acid production, which have a substantially greater global warming potential than carbon dioxide.
For information relevant to California Assembly Bill 1305, including project registration, verification status, methodology, and third-party verification, please refer to the Climate Action Reserve project registry linked above.
*Scope 3 emissions currently include business travel and remote work emissions only, pending a full materiality assessment to identify additional relevant emission categories.
