Primary: PAS 2080 carbon management embedding in contracting business (JNB) 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.

Dependent: Supply chain engagement — low carbon procurement and science-based targets 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.

Procurement of 100% renewable electricity across global offices 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.

Data optimisation tool improves carbon footprint calculation accuracy In 2023 Mott MacDonald deployed an in-house data optimisation solution for carbon footprint calculation for the first time, replacing manual processes. Improvements in emission factor libraries and estimation methods led to recalculation of 2019 baseline and 2022 figures to ensure consistency. Historical data in Tables 1-3 may differ from previously published values.

Primary: Business travel reduction via behaviour change policies 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.
