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.
sustainability_report p.7
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.
sustainability_report p.7
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.
sustainability_report p.7
The firm's primary operational decarbonisation lever is switching office energy (electricity and gas) to renewable and low-carbon sources.

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.
sustainability_report p.7
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.
sustainability_report p.8
As a result of the data optimisation project, the 2019 baseline and 2022 emissions data displayed in Tables 1-3 were recalculated using the 2023 footprint methodology. Primary changes: avoidance of manual error, updated emission factor libraries, improved estimation methods.

Business travel is explicitly included in the near-term SBTi target of 28% absolute reduction by 2030.
sustainability_report p.5
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.
sustainability_report p.5
