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.
How the firm describes its decarbonisation approach in its own words — alongside the headline numbers above. Self-reported, page-cited.
Mott MacDonald has continued to increase procurement of renewable energy for its offices, driven by regional targets to achieve 100% renewable electricity. MML's market-based Scope 2 emissions fell from 2,261 tCO2e in 2019 to 137 tCO2e in 2023. The JNB contracting business has also generated significant energy efficiency improvements through switching to higher Energy Performance Certificate (A/B) rated site cabins. No PPAs are explicitly disclosed; procurement appears to be via green tariffs / renewable supply contracts at the regional office level.
Mott MacDonald's net-zero plan focuses on absolute emissions reductions (-90% by 2040 from 2019 baseline) rather than relying on carbon removals or offsets. The report does not disclose any DAC, BECCS, afforestation, or removal-credit purchases. Biogenic emissions and removals are tracked separately within the ISO 14064 inventory but their net impact is reported as 0 tCO2e. SBTi-validated targets are framed as absolute reductions across scopes 1, 2 and 3.
Office energy (electricity and gas) consumption fell from 15.2 GWh in 2019 to 6.5 GWh in 2024, a ~57% reduction. Combined scope 1 office gas and fugitive emissions plus scope 2 market-based electricity sit at 524 tCO2e in 2024 versus 3,183 tCO2e in 2019.
Business travel from hire-vehicle cars is the dominant scope-3 category MML tracks, at 3,007 tCO2e in 2024 (up from 2,224 in 2023 but down from a 2019 baseline of 3,254). It is the only scope 3 category captured in MML's SECR boundary, suggesting a primary lever for the UK consultancy footprint.
Employee commuting emissions are tracked alongside business travel within the near-term reduction target. Reduced commuting to offices is cited as a driver of the 42% scope 3 reduction vs. 2019 baseline. Group cat 7 emissions fell from 14,750 tCO2e (2019) to 8,975 tCO2e (2023).
Business travel is one of MML's largest scope 3 categories. In 2023, the firm introduced non-compliance when booking flights travelling within mainland Britain as the first policy measure to reduce travel emissions. Group business travel rose from 15,919 tCO2e in 2022 to 19,907 in 2023 (still 49% below the 2019 baseline of 39,147). Further behaviour-change measures are planned via regional carbon reduction plans.
Office gas/electricity consumption at MML fell from 15.7m kWh (2019) to 7.6m kWh (2023). The programme of moving office energy to renewable and low-carbon sources is the main driver of the 35% combined Scope 1+2 reduction vs. 2019 baseline. JNB has switched site cabins to A/B EPC-rated units.
In 2023 introduced non-compliance policy when booking flights travelling within mainland Britain — the first behaviour-change policy measure to reduce business travel emissions. Further measures to be informed by regional carbon reduction plans. Scope 3 business travel (MMGL) was 19,907 tCO2e in 2023, up from 15,919 in 2022 but down from 39,147 in 2019.
Office energy emissions reduced via shift to renewable electricity contracts. JNB has generated significant energy efficiency improvements through switching to higher EPC-rated (A/B) site cabins for construction activities.
PAS 2080:2023 verification used to embed carbon management in design decisions across infrastructure and buildings work. In 2023 set up a working group within JNB contracting business to pursue PAS 2080 certified contractor status. Embedding PAS 2080 principles in decision making is a key element of the net-zero plan for the contracting business.
Business travel is the largest growing Scope 3 category at MMGL (15,131 tCO2e in 2022 vs 6,280 in 2021 as travel rebounded post-Covid; baseline was 22,293 in 2019). Investigating low carbon travel choices and mechanisms to ensure staff can reduce their emissions; SBTi target requires 28% absolute reduction by 2030.
The Carbon Reduction Plan calls for investigating low carbon travel choices and mechanisms to ensure staff can reduce their emissions. However, business travel emissions rebounded sharply in 2022 (15,131 tCO2e vs 6,280 in 2021) as post-Covid travel resumed, remaining below the 2019 baseline of 22,293 tCO2e.
Employee commuting emissions (Cat 7) of 10,232 tCO2e in 2022, included in SBTi 28% Scope-3 reduction target by 2030. Behavioural change programmes and low-carbon travel mechanisms are being investigated as part of the Group Carbon Reduction Plan.
The Group Carbon Reduction Plan is supplemented by commitment to support beyond value chain mitigation (BVCM), a key requirement on the journey to net zero according to SBTi. Mott MacDonald endeavours to support BVCM through continuing to purchase carbon credits which align to their purpose.
The Group Carbon Reduction Plan includes switching to renewable energy supplies and driving energy efficiency across our offices. Scope 2 market-based electricity emissions remain modest (3,465 tCO2e in 2022) reflecting renewable procurement, while office gas/fuel scope 1 fell from 13,375 to 7,819 tCO2e year-on-year.
Office gas, fuel and fugitive emissions (Scope 1) fell from 13,947 tCO2e in 2019 to 7,819 in 2022. Plan focuses on improved data, renewable electricity procurement and energy efficiency across the office estate.
Reducing intercontinental travel is a stated lever. Updated the Travel Policy and initiated behavioural change to support low carbon modes of transport. A carbon incentivisation scheme is being investigated. MML business travel — car emissions fell from 836 tCO2e (2020) to 512 tCO2e (2021).

JNB continues to invest in greener plant for its plant fleet and is communicating with the wider business and supply chain on the MMBC electrification road map of how the company vehicle fleet will become fully electric in the coming years.
Reducing business travel flights is a stated activity in the carbon neutral plan. In 2020, business travel car emissions were 840 tCO2e on 2,692,463 kWh of business travel car energy. COVID-19 lockdowns indirectly reduced travel-related emissions.
Mott MacDonald is moving towards renewable energy in offices to reduce Scope 2 emissions (1,479 tCO2e location-based in 2020 across MML + JNB) and office gas (Scope 1: 885 tCO2e combined).

Purchased goods and services is by far MML's largest scope 3 category (164,680 tCO2e in 2023, 74% of scope 3). The firm aims for 70% of suppliers by spend to have science-based targets by 2027. A supplier was appointed in 2023 to facilitate carbon engagement and data gathering across the supply chain, with additional carbon questions added to due-diligence processes.
Mott MacDonald has been PAS 2080 certified as a designer since 2017 and was independently verified to the PAS 2080:2023 revision in 2023.
