Carbon per million dollars of revenue. The legacy industry-standard reference (CDP, MSCI). Useful for cross-sector context, but distorted by margin — high-margin firms appear artificially efficient. Read alongside the operational and asset intensities for the full picture.

OpEx (operating expenditure) is the running cost of the business — staff, services, energy, materials. This shows how carbon-intensive operations are per million dollars of spend. Removes the margin distortion that revenue-based ratios introduce.

EVIC (Enterprise Value Including Cash) is the firm's total capital footprint — equity + debt + cash + minority interest. The EU's standard intensity measure (SFDR PAI 3) — answers: how much carbon does each million of capital deployed in this business produce?

PP&E (Property, Plant & Equipment) plus leased real-estate assets is the firm's physical infrastructure on the balance sheet. This shows the carbon intensity of that physical footprint — uses Scope 1+2+3 for consistency with the other headline intensities. Surfaces stranded-asset risk for asset-heavy firms.

Carbon per FTE (full-time-equivalent employee) — the diagnostic measure for people-leveraged businesses where headcount, not capital, drives delivery. Captures the office, energy and travel footprint per person.

Booz Allen reports 0 MWh from renewable sources in FY24 across all energy categories. All facilities are 100% leased from third parties, meaning Booz Allen does not currently have access to contractual instruments or utility company emission factors. The facilities teams continue to work with landlords and property managers to seek arrangements by which utility information and renewable energy options may be made available. No RECs, PPAs, or green tariffs are currently in place, resulting in a 0% renewable energy figure.

Booz Allen's net-zero target (SBTi-approved, FY2050) states the firm is 'unsure' whether it intends to neutralize residual emissions with permanent carbon removals at the end of the target period. The firm plans to mitigate emissions beyond its value chain within the next two years (beyond value chain mitigation, BVCM). No carbon removals or offsets have been retired in the current reporting year. The transition plan, currently under development, is expected to clarify the approach to residual emissions within two years.

• Cross-functional Climate Impact Initiative driving enterprise-wide decarbonisation

  Booz Allen has formalised a cross-functional Climate Impact Initiative aligned to its SBTi-validated targets and net-zero 2050 commitment. The initiative encompasses four workstreams: (1) reducing Scope 1 and 2 emissions, (2) engaging the value chain to reduce Scope 3 emissions, (3) partnering with business leaders to integrate climate into business strategy and value proposition, and (4) empowering employee groups via the Sustainability Engagement Network (SEN) to drive local facility-level greening activities. The ERS Committee (chaired by the Chief Legal Officer) provides executive oversight with quarterly Board reporting.

• Business travel reduction as dominant Scope 3 Category 6 lever

  Business travel (Cat 6) is one of the two largest Scope 3 emission sources at 43,813 tCO2e in FY24, covering air travel, car rentals, personal vehicle mileage, and hotel stays. Booz Allen's SBTi near-term target (Abs2) covers 90% of Cat 6 emissions with a 50.4% reduction goal by FY2032. The firm employs a proactive telework strategy providing employees flexibility to conduct business remotely, reducing travel demand. Travel emissions are tracked through primary travel service providers (air, rental car agencies) using GHG Protocol factors; 90% of Cat 6 emissions are from supplier-specific data.

• Office energy efficiency and space consolidation to reduce Scope 1+2

  Booz Allen's primary Scope 1+2 lever is reducing energy use in its 100% leased office portfolio. In FY24, one energy efficiency initiative is underway with estimated annual savings of 1,250 tCO2e in Scope 2 and Cat 3. The Real Estate team is pursuing broad-scale space optimisation including leased building characteristics and energy-efficient design elements. Scope 2 emissions fell from 12,292 tCO2e (FY23) to 10,446 tCO2e (FY24), partly due to workspace consolidation reducing leased square footage. The firm's SBTi Abs1 target requires a 50.4% reduction in Scope 1+2 by FY2032 from a FY2020 baseline of ~15,147 tCO2e.

• Employee commuting and telework emissions reduction (Scope 3 Cat 7)

  Employee commuting (Cat 7) is the largest Scope 3 category at 44,218 tCO2e in FY24, including both physical commuting and telework energy emissions. Booz Allen conducts an annual voluntary employee commuting survey to estimate commuting footprints by mode and distance. Due to Booz Allen's hybrid working situation, telework emissions from electricity and natural gas at employees' homes are included using Anthesis and US EPA factors. The SBTi near-term target (Abs2) covers 90% of Cat 7 with a 50.4% reduction target by FY2032. Hybrid work policy is a key lever for reducing this category.

• Employee commuting footprint management including remote work

  Booz Allen estimates employee commuting emissions (7,302.7 tCO2e in FY22) using a voluntary annual survey and distance-based methodology. Due to COVID-19 telework policies in FY21 and FY22, FY20 survey data was extrapolated using badging data to estimate in-office attendance. Greater than 85% of workforce was in mandatory telework during FY21, materially reducing commuting emissions. Remote work is recognized as a lever for reducing this category.

• Facilities energy management through utility data access

  Booz Allen leases all office space (~2.5 million sq ft) and does not own or manage buildings, making Scope 2 the primary operational emissions source. In FY2022, actual utility bill kWh data was accessed for 19 facilities comprising ~41% of total leased square footage, improving accuracy over estimation methods. The firm continues working with landlords and property managers to expand utility data access. All remaining facilities use estimation based on occupied square footage.

• SBTi-aligned target-setting via Climate Impact Initiative

  In FY22, Booz Allen's ESG Committee launched the Climate Impact Initiative to set SBTi-validated targets for Scope 1, 2, and 3 emissions within 2 years, using FY2020 as the baseline. The initiative is organized around four objectives: Reduce Our Emissions; Reduce the Emissions of Our Value Chain; Integrate Climate into Business Strategy; and Influence Climate Action in Society. The firm joined the Business Ambition for 1.5°C campaign and committed to net-zero no later than 2050.

• Business travel emissions tracking and reduction

  Booz Allen tracks Scope 3 business travel emissions (12,009.64 tCO2e in FY22) in collaboration with its travel service provider, capturing airline flight segments, rental car mileage, hotel stays, and personal vehicle use. EPA Climate Leaders emission factors and UK Government GHG Conversion Factors are used. 99% of emissions are calculated using supplier data. Business travel is a dominant Scope 3 category for the firm and is subject to third-party limited assurance.

• Office space optimization via NexGen Strategy

  Booz Allen's NexGen Strategy optimizes office space and design, adopting an open workspace concept with more natural lighting, enhanced connectivity tools, and a variety of work spaces while reducing square footage and energy use. This initiative is in the implementation commenced phase with an estimated annual CO2e saving of 3,000 tCO2e from Scope 2 (location-based) emissions. It is classified as voluntary with an ongoing lifetime and no payback requirement.

• Supply chain engagement to reduce Scope 3 Cat 1 purchased goods and services

  Purchased goods and services (Cat 1) is the largest absolute Scope 3 category at 271,453 tCO2e in FY24, a significant increase from FY23 due to methodology expansion to include non-sourceable spend. Booz Allen uses dollar spend data matched to USEEIO NAICS emissions factors. The firm is working to implement a sustainable supply chain programme and plans to introduce environmental requirements for suppliers within the next two years. Suppliers are prioritised based on leverage. The SBTi near-term target (Abs2) covers 90% of Cat 1 with a 50.4% reduction target by FY2032. Future engagement will focus on direct emissions data from key suppliers.

• Supply chain climate requirements and value chain engagement

  Booz Allen currently does not require suppliers to meet climate-related requirements but plans to introduce them within the next two years. Engagement with suppliers and subcontractors occurs via a Supplier Code of Conduct, small business program, and mentor-protege program. The Climate Impact Initiative includes an objective to 'Reduce the Emissions of Our Value Chain,' and Scope 3 Category 1 (purchased goods and services) is identified as relevant but not yet calculated.
