The emissions reduction tool local authorities are using to measure what matters most
Most local authorities and public sector organisations already measure Scopes 1 and 2, and some parts of Scope 3. But the biggest contributors - procurement, estates and capital projects - are often left out.
Councils like Mid Sussex are already using CarbonTrack to bring these emissions into view and embed carbon reduction into procurement and policy.

The 90% of Emissions That Are Often Hidden
Scopes 1 and 2 are only part of the story. Procurement, estates and capital projects can make up as much as 90% of an organisation’s footprint – yet they are the least measured and hardest to manage.
Procurement Emissions
Services you buy often
account for the largest
share. CarbonTrack
identifies the suppliers that
matter most and helps
align contracts with climate
goals
Estate Emissions
Leased or indirectly
managed assets are often
excluded from reporting.
CarbonTrack brings them
into scope, closing a major
gap
Capital Expenditure Emissions
New housing, schools and
infrastructure carry
significant embedded
emissions. CarbonTrack
ensures these are factored
into planning and
investment decisions

CarbonTrack for the Public Sector: Helping Councils and Public Bodies Lead On Net Zero
Most local authorities have ambitious climate commitments, but procurement, estates and capital projects often sit outside their reporting.
CarbonTrack helps councils close this gap, benchmark progress against peers and embed carbon reduction into procurement and policy. The tool is already being used by local authorities such as Mid Sussex District Council, Crawley Borough Council. Mole Valley District Council and Portsmouth City Council.
Our Services - From Measurement to Action: Your Complete Pathway to Net Zero
Carbon Accounting
CarbonTrack partners with you to deliver a comprehensive, highly granular Scope 3 baseline using expert-led analysis and powerful analytical tools. We guide your team through data collection and interpretation to reveal the distribution of emissions across suppliers, categories, and buildings, ensuring you get a complete, action-ready picture of your total footprint.
Net Zero Procurement
We move beyond measurement by providing a structured, phased pathway for engaging your supply chain and embedding carbon reduction into procurement policy. Our consultancy approach co-develops a tailored framework with your teams, helping you navigate the 'double bind' of statutory obligations while turning your net zero ambition into practical, compliant action.
SME Capacity Building
Recognising that many key suppliers are SMEs who lack resources, we provide capacity building support to accelerate your own Scope 3 progress. This includes on-site Carbon Maturity Assessments and Carbon Literacy Training, turning supplier resistance into partnership and directly improving your supply chain's data collection and emissions reduction capability.
Net Zero Pathway Modelling
Using your complete carbon baseline, we facilitate decision-making sessions with your team to model a realistic, evidence-based pathway to net zero. We map out tangible abatement projections by category, identify resource allocation requirements, and model cost implications, transforming analysis into an actionable, politically sensitive implementation plan.
