What Is a Carbon Footprint Consultant? Measurement, Scopes 1-3, Product Footprints, and How to Hire One

Example Projects

1. Corporate Carbon Footprint (Scopes 1, 2, and 3)
   Complete organisational emissions measurement including boundary setting, activity data collection, emission factor selection, and calculation across all relevant scopes and categories. The output is an audit-ready emissions report with full methodology documentation, suitable for SECR disclosure, CDP submission, and SBTi baseline setting.
2. Scope 3 Value Chain Assessment
   A focused assessment of your value chain emissions across all 15 Scope 3 categories, identifying which are material and calculating emissions using spend-based, activity-based, or supplier-specific methodologies. Scope 3 is typically 70-90% of total emissions but the most complex to measure. The assessment identifies hotspots and provides the data needed for SBTi Scope 3 target setting and supplier engagement programmes.
3. Product Carbon Footprint
   Assessment of emissions embedded in specific products or services following PAS 2050 or ISO 14067. This supports carbon labelling initiatives, customer requests for product-level data, life cycle assessment programmes, and Scope 3 supplier data provision. Product footprinting is increasingly important for consumer goods, food and beverage, construction materials, and packaging companies.
4. Carbon Footprint for Reporting and Compliance
   Preparation of emissions data specifically for regulatory and voluntary reporting frameworks, including SECR for UK annual reports, CDP questionnaire responses, UK SRS S2 climate metrics, and CSRD/ESRS E1 reporting. This includes ensuring data quality, methodology transparency, and readiness for external assurance.
5. Baseline Setting for Science-Based Targets
   Establishing the emissions baseline year and methodology needed for SBTi target validation. This requires specific data quality standards, boundary definitions, and recalculation policies that go beyond a standard carbon footprint exercise.

Who Do They Work With?

Carbon footprint consultants work with sustainability teams on measurement and reporting, operations and facilities on Scope 1 and 2 data, procurement and supply chain on Scope 3 data collection, product development on product-level footprinting, finance on emissions data for financial reporting, and external auditors on assurance preparation.

Who Should Hire a Carbon Footprint Consultant?

Organisations conducting their first carbon footprint who need to get the methodology right from the start. Companies with existing footprints that need improvement, particularly moving from spend-based to activity-based Scope 3 calculations. Businesses responding to customer or investor requests for emissions data. Companies setting SBTi targets that require a validated baseline. Organisations preparing for UK SRS or CSRD that need assurance-ready emissions data. Any company that reports or intends to report greenhouse gas emissions benefits from specialist carbon footprinting expertise.

ROI and Strategic Benefits

Accurate carbon footprinting is the foundation for everything that follows: credible targets, effective reduction investment, regulatory compliance, and stakeholder communication. Poor data leads to misallocated investment, non-credible claims, and compliance risk. A specialist consultant ensures your footprint is decision-useful and audit-ready, typically at a cost that is a fraction of the downstream value it enables.
