Global Scope 3 Re-baselining

Rebuilding a multinational historic inventory to improve consistency, transparency and data quality.

Challenge: A multinational emissions inventory contained inconsistent historic supplier classifications, emissions-factor choices and data coverage across reporting periods.
Approach: The work combined large-scale data profiling with targeted review of the suppliers, categories and assumptions that materially affected the footprint.
Work undertaken: Historic re-baselining
Supplier classification
Emissions-factor methodology
Inflation adjustments
High-emitter reviews
Reduction of unclassified spend
Methodology and data-quality documentation
Outcome: The revised approach produced a more transparent and consistent historic dataset, with clearer explanations of methodological changes and the sources driving reported emissions.
Why it mattered: A credible baseline is essential for distinguishing real emissions reductions from changes in data coverage or methodology.
Capabilities demonstrated: Scope 3
Re-baselining
Data analytics
Materiality
Methodology

Construction Carbon Boundaries

Defining practical Scope 3 responsibility across clients, contractors and complex project structures.

Challenge: Complex construction arrangements created uncertainty about which party should report emissions and where influence was being mistaken for emissions ownership.
Approach: GHG Protocol principles were translated into practical tests based on contractual responsibility, discretion, operational control and the risk of double counting.
Work undertaken: Scope 3 boundary assessment
Contract-holder test
Discretion test
Client and contractor responsibility analysis
Double-counting review
Influence versus ownership analysis
Practical decision guidance
Outcome: The analysis created a consistent basis for assigning emissions responsibility across different project and contracting scenarios.
Why it mattered: Clear boundaries improve comparability and prevent organisations from reporting emissions based on influence alone or omitting them between parties.
Capabilities demonstrated: GHG Protocol
Scope 3 boundaries

Construction carbon

Scope 3 Data & Reporting Transformation

Designing scalable supplier mapping, controls and automation for emissions reporting.

Challenge: Supplier and reporting data required extensive manual classification and reconciliation, limiting consistency and the ability to scale the reporting process.
Approach: The work reviewed the emissions-management platform and designed stronger supplier, classification, factor-mapping and quality-control processes around it.
Work undertaken: Emissions-management software review
Implementation support
Supplier and parent-company mapping
DUNS and industry classifications
Emissions-factor mapping
Quality controls
Automation design
Machine-learning classification opportunities
Outcome: The resulting design established a more controlled and scalable reporting process, with clearer mappings and targeted opportunities for automation.
Why it mattered: Reliable Scope 3 reporting depends on repeatable data architecture, not repeated manual correction at the end of each reporting cycle.
Capabilities demonstrated: Scope 3 data
Systems implementation
Supplier mapping
Automation
Controls

Electric Fleet Transition & Infrastructure Business Case

Comparing vehicles, charging infrastructure and depot requirements through whole-life commercial analysis.

Challenge: A fleet transition decision required more than comparing vehicle prices: infrastructure, operations, energy use and carbon implications all affected feasibility.
Approach: Electric, diesel and hybrid options were compared through an integrated model covering acquisition, operation, maintenance, charging and depot conversion.
Work undertaken: Vehicle acquisition costs
Energy use and cost per mile
Maintenance assumptions
Charging infrastructure
Depot conversion
CAPEX and OPEX
Whole-life cost
Operational constraints
Scope 1 and 2 implications
Outcome: The analysis provided a consistent basis for comparing transition options and identifying the infrastructure and operational decisions required alongside vehicle replacement.
Why it mattered: Fleet electrification is an infrastructure and operating-model decision as well as a vehicle procurement decision.
Capabilities demonstrated: Fleet electrification
Financial modelling
Infrastructure
Whole-life cost
Carbon analysis

How the work connects

Strategy

Define priorities, compare options and connect sustainability objectives to investment and delivery decisions.

Governance & Data

Establish clear boundaries, ownership, methodology, data lineage, controls and evidence.

Delivery

Build implementation roadmaps, mobilise workstreams and create practical monitoring tools and processes.
