    Why Carbon Footprinting Matters

    Carbon footprinting plays a vital role in helping organisations set and track Net Zero and Science-Based Targets, establish robust baselines for emissions reduction, and align with frameworks like SBTi.


       

    • Set and Track Net Zero and Science-Based Targets: establish robust baselines to develop aligned reduction pathways in line with SBTi, sectoral decarbonisation approaches, or corporate Net Zero strategies. 
    • Support ESG & Climate-Related Disclosures: provide verifiable carbon data for stakeholder reporting through frameworks such as CDP, TCFD, SECR, CSRD, GRESB, SFDR, and annual sustainability reports. 
    • Strengthen Climate Risk Management: understand your exposure to transition and operational risks, such as carbon pricing, regulation, and investor scrutiny – across global operations and supply chains. 
    • Identify Emissions Hotspots Across Operations & Supply Chains: pinpoint high-impact activities, assets, or suppliers to prioritise decarbonisation efforts and optimise resource allocation. 
    • Enable Evidence-Based Carbon Reduction Planning: quantify emissions from existing systems, model future scenarios, and evaluate the effectiveness of low-carbon interventions. 
    • Improve Operational Efficiency & Cost Savings: use footprinting to uncover inefficiencies (e.g. energy, logistics, materials) and link emissions reduction to cost optimisation. 

    What We Calculate

    Organisational Carbon Footprint – Calculation of your total emissions inventory across:

     

    • Scope 1 – Direct emissions (e.g. fuel combustion, company vehicles)
    • Scope 2 – Indirect emissions from purchased electricity, heat, or steam
    • Scope 3 – Value chain emissions (optional but increasingly expected), including:
      • Purchased goods and service
      • Business travel, employee commuting
      • Waste, water, and leased assets
      • Investments and product use

    Product or Service Carbon Footprint – Lifecycle-based footprinting (Cradle-to-Gate or Cradle-to-Grave) aligned with:

     

    • GHG Protocol Product Standard
    • ISO 14067 / PAS 2050

    Scoping & Boundary Definition

    A robust carbon footprint starts with clearly defined boundaries. We work closely with clients to identify material emission sources and establish organisational and operational boundaries in line with the Greenhouse Gas (GHG) Protocol. This ensures consistency, transparency, and readiness for external assurance or reporting. Whether you’re calculating emissions for a single site or a complex portfolio, our approach lays the foundation for credible and decision-useful carbon data.
     
    Our approach includes:

       

    • Identification of material emission sources across Scope 1, 2 and relevant Scope 3 categories.
    • Definition of organisational boundaries using equity share or control approaches.
    • Operational boundary setting to determine which activities and assets are included.
    • Alignment with GHG Protocol principles for consistency, completeness, and transparency.
    • Support for assurance readiness through traceable methodologies and documentation.
    • Custom scoping for specific reporting needs, such as SECR, ESOS, or net zero strategies.
    carbon-footprint consultants

    Data Collection & Emissions Calculation

    We take a structured approach to data collection and emissions quantification, ensuring accuracy across all relevant scopes. By mapping operational data flows, we identify key activity data and apply verified emissions factors to calculate greenhouse gas outputs. Where gaps exist, we use transparent estimation methods to maintain consistency. Our calculations span Scope 1 (direct), Scope 2 (energy-related), and Scope 3 (indirect value chain) emissions, offering a full view of your carbon impact.

     
    Our process includes:

    • Mapping data flows across assets, operations, and supply chains
    • Applying verified emissions factors from sources like DEFRA, BEIS, and GHG Protocol
    • Estimating data gaps with transparent, credible methods
    • Covering Scope 1, 2, and 3 emissions, tailored to your organisation
    • Validating data quality for audit readiness
    • Supporting reporting frameworks
    carbon-footprint consultants

    Emissions Profiling & Benchmarking

    We provide detailed emissions profiling to help organisations understand where their carbon impacts are concentrated. By analysing emissions by unit, asset, or activity category, we identify hotspots and opportunities for targeted reduction. We also benchmark emissions intensity against sector standards and peer organisations, giving clients a clear view of performance and progress. This insight supports strategic planning, reporting, and engagement with stakeholders around climate goals.
     

    Our profiling and benchmarking services include:

       

    • Breakdown of emissions by unit, asset, or operational category to highlight key contributors.
    • Hotspot analysis to identify areas of high carbon intensity or inefficiency.
    • Benchmarking against sector standards and industry peers to contextualise performance.
    • Trend analysis over time to track progress and inform future strategy.
    • Visual dashboards and reports to support internal and external communication.
    • Recommendations for targeted interventions based on profiling insights.
    carbon-footprint consultants

    GHG Inventory & Disclosure Alignment

    We produce robust, auditable greenhouse gas inventories that meet the requirements of leading disclosure frameworks. Our outputs are structured to align with CDP, SECR, CSRD, TCFD, and SFDR, ensuring consistency, transparency, and readiness for external reporting or assurance. Whether you’re preparing for investor disclosures, regulatory compliance, or voluntary reporting, we help you present your carbon data with confidence and credibility.
     
    Our services include:

       

    • Development of auditable GHG inventories covering Scope 1, 2, and 3 emissions.

    Frequently Asked Questions

    What’s the difference between Scope 1, 2, and 3 emissions?

    Scope 1 and 2 cover your direct operations and energy use; Scope 3 covers your upstream and downstream value chain emissions. Scope 3 is often the largest component—and increasingly expected in disclosures.

    How long does a carbon footprint project take?

    Timelines vary based on data availability, company size, and number of sites. A typical footprint takes 4–8 weeks; complex Scope 3 or product LCAs may take longer.

    Do I need third-party verification?

    Not mandatory, but verification (e.g. ISO 14064-3) improves credibility—especially for public or investor reporting. We support pre-verification preparation or connect you with assurance partners.
