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. The reduction in Scope 1 and 2 emissions is explicitly attributed to the programme of moving office energy to renewable and low-carbon sources. JN Bentley (contracting business) has also generated energy efficiency improvements by switching to higher energy performance rated site cabins.
MMGL's commitment to net zero by 2040 per SBTi is supplemented by a commitment to support beyond value chain mitigation (BVCM), which is a key SBTi requirement on the journey to net zero. MMGL endeavours to support BVCM by continuing to purchase carbon credits which align to its purpose. No specific volumes of credits or removal types (e.g. DAC, BECCS) are disclosed in this report.
MML tracks office electricity and gas consumption (combined 6.5m kWh in 2024 vs 7.4m kWh in 2023) as part of its SECR obligations. Scope 1 office gas and fugitive emissions fell to 418 tCO2e in 2024 from 632 tCO2e in 2023 and a 2019 baseline of 1,071 tCO2e, indicating material reductions. Market-based Scope 2 electricity emissions were 106 tCO2e in 2024. An Environmental Management System (EMS) drives continual improvement across the organisation to reduce GHG emissions and energy consumption.
MML implements and maintains an Environmental Management System across the organisation, driving continual improvement to reduce GHG emissions and energy consumption. The carbon footprint methodology is documented through method statements for each emission source, with the carbon footprint verified to ISO 14064. Conversion factors from the UK Department for Energy Security and Net Zero are applied. The Group falls under the UK Companies (Strategic Report)(Climate-related Financial Disclosures) Regulations 2022, with full TCFD disclosure at Group level.
Scope 3 business travel from hire vehicles is the dominant component of MML's UK SECR inventory at 3,007 tCO2e in 2024 (2023: 2,224 tCO2e; 2019 baseline: 3,254 tCO2e). Car travel energy consumption was 10.8m kWh in 2024. The report notes that for a full emissions inventory including all business travel modes, readers should refer to the Group statement, implying broader travel reduction initiatives are managed at Group level.
Mott MacDonald has been PAS 2080 certified as a designer since 2017. In 2023, a working group was established within JN Bentley (contracting business) to work towards PAS 2080 certification as a contractor. Embedding PAS 2080 carbon management principles in decision-making is described as a key element of the net-zero plan for the contracting business.
The firm's primary operational decarbonisation lever is switching office energy (electricity and gas) to renewable and low-carbon sources. Scope 2 market-based emissions fell from 9,031 tCO2e (2019 baseline) to 4,246 tCO2e in 2023, a 53% reduction, driven by renewable energy procurement across global offices.
In 2023, Mott MacDonald introduced its first policy measure to reduce business travel emissions: non-compliance when booking flights travelling within mainland Britain. The policy was informed by the carbon footprint and additional measures will be introduced based on regional carbon reduction plans. Scope 3 Category 6 (business travel) fell from 39,147 tCO2e in 2019 to 19,907 tCO2e in 2023.
Scope 3 Category 7 (employee commuting) fell from 14,750 tCO2e in 2019 to 8,975 tCO2e in 2023, partly attributed to reduced commuting to offices. The Group's carbon reduction plan explicitly references reduced commuting alongside business travel reduction as drivers of Scope 3 improvement.
JN Bentley (contracting subsidiary) is developing an electrification road map for its company fleet to become fully electric. JNB is investing in low-carbon plant and working with plant hire companies to trial innovative technologies such as solar hybrid solutions. JNB's grey fleet and company vehicles represent significant Scope 1 emissions (3,996 tCO2e plant energy + 1,881 tCO2e company vehicles in 2022).
Business travel (Scope 3 Cat 6) is a material category for MMGL, recovering to 15,131 tCO2e in 2022 from a Covid-suppressed 6,280 tCO2e in 2021. The Group Carbon Reduction Plan includes investigating behavioural change measures supporting carbon reduction and investigating low-carbon choices and mechanisms to ensure staff can reduce their emissions. Business travel is explicitly included in the near-term SBTi target of 28% absolute reduction by 2030.
MMGL is committed to switching to renewable energy supplies and driving energy efficiency across its offices as part of its Group Carbon Reduction Plan. The UK MML entity reported total office energy (electricity and fuel) of 8.4 million kWh in 2022. Scope 1 office gas emissions and market-based Scope 2 electricity emissions are primary targets under the 46.2% near-term reduction commitment for Scopes 1 and 2 by 2030.
Employee commuting (Scope 3 Cat 7) reached 10,232 tCO2e in 2022, included in MMGL's near-term SBTi target of 28% reduction from fuel and energy related activities, waste, business travel, and employee commuting by 2030 from a 2019 base. The Group Carbon Reduction Plan includes measures to support staff in reducing their commuting emissions.
Scope 3 car business travel for MML fell from 836 to 512 tCO2e (2020–2021), driven by reduced hire vehicle use. The company updated its Travel Policy to support low carbon modes of transport and specifically listed reducing intercontinental travel and switching hired vehicles to a hybrid/electric fleet as key carbon reduction actions in its carbon neutral plan.
MML's SECR-reported Scope 1 office fuel emissions fell from 902 to 742 tCO2e between 2020 and 2021. Total office energy (electricity and fuel) was 9,265,213 kWh in 2021 vs 10,185,359 kWh in 2020. The company is improving energy efficiency in its offices, switching to renewable energy, and minimising waste as part of its carbon management process.
MML continues to offset residual emissions and maintains PAS 2060 Carbon Neutral certification. The 2019 and 2020 global carbon footprints were offset through restoration of peatland in Indonesia. MML is committed to driving down the need to offset as fast as possible, progressively improving the quality of offsets and developing its own offsetting projects for the longer term.
Plans include moving to renewable energy in offices and switching hired vehicles to a hybrid/electric fleet as set out in an Electrification Roadmap (primarily applicable to JN Bentley subsidiary). Office gas (Scope 1) and location-based electricity (Scope 2) together totalled 2,182 tCO2e for Mott MacDonald Limited in 2020.
Mott MacDonald's carbon neutral plan explicitly includes reducing business travel flights as a key action. The SECR data shows Scope 3 car travel emissions of 840 tCO2e for the UK entity in 2020. COVID-19 restrictions in 2020 also contributed to a reduction in travel-related costs and emissions.
The carbon neutral plan includes more robust carbon management and exploration of potential for an internal carbon reduction incentivisation scheme. The company is also implementing early roadmap activities including embedding significant carbon reduction into operational business, reporting and developing in relation to Science Based Targets and carbon neutrality.
Mott MacDonald's certification to PAS 2080:2023 (carbon management for buildings and infrastructure, co-authored by MML in 2016 and updated in 2023) illustrates the firm's capability to embed carbon management into client projects. An internal project assessment tool evaluates sustainability complexity and risks across the project lifecycle. The firm is involved in renewable energy connectivity projects, including supporting National Grid on high-voltage links for offshore wind integration.
A key element of Mott MacDonald's near-term SBTi target is engaging suppliers on carbon reduction. In 2023, the firm appointed a supplier to facilitate communications, engagement and data gathering from the supply chain around carbon. Additional due diligence questions on carbon were added across the Group. The aim is for 70% of suppliers by spend to have science-based targets by 2027.
MMGL commits that 70% of its suppliers by spend covering purchased goods and services, capital goods, and upstream transportation and distribution will have science-based targets by 2027. Purchased goods and services (Cat 1) dominates MMGL's Scope 3 at 136,281 tCO2e (2022) and the plan includes investigating alternative sources for procurement to ensure a low-carbon supply chain.
MML is investigating alternative sources for procurement to ensure only low carbon choices are made. A carbon incentivisation scheme is under investigation. The company is also working to communicate the MMBC electrification road map to the wider supply chain, and conducting due diligence on suppliers for sustainability.
Mott MacDonald advises clients on net-zero pathways — e.g. developing a strategy for Highways England to achieve net-zero across its 4,300-mile road network, and delivering the £3m BEIS 2050 Calculator programme. The company has committed to understanding which projects may not be appropriate for a net-zero future and linking this with TCFD reporting.
