    FAQ

    Frequently Asked Questions

    What is a carbon footprint calculator?
    A carbon footprint calculator estimates the total greenhouse gas (GHG) emissions produced by your business activities. Measure your emissions accurately. It covers Scope 1 direct emissions, Scope 2 electricity consumption, and Scope 3 supply chain spending. Our free calculator uses official EPA GHG Emission Factors Hub data for methodology-aligned results. Know your carbon intensity.
    How do I calculate my business carbon footprint for free?
    Upload your bank CSV or enter activity data directly into our free carbon footprint calculator. Upload your bank CSV. The tool automatically categorizes your operational spend, estimates activity data where needed, and computes Scope 1, 2, and 3 emissions using EPA emission factors. You get a full report with carbon intensity benchmarks in your browser without creating an account.
    What are Scope 1, Scope 2, and Scope 3 emissions?
    Scope 1 covers direct emissions from owned fuel combustion and company vehicles. Scope 2 covers indirect emissions from purchased electricity and steam. Scope 3 covers all other value chain activities including business travel, commuting, shipping, and waste disposal. Scope 3 dominates footprints. Our carbon footprint calculator computes all three scopes automatically.
    What data do I need to use this carbon footprint calculator?
    You can either upload a bank CSV or enter activity metrics directly. Enter utility meter data. For best results, provide electricity consumption in kWh, fuel purchases in gallons, travel miles, and waste tonnage. Optional fields like revenue and headcount unlock revenue-normalized carbon intensity scoring.
    Is this carbon footprint calculator free to use?
    Yes, completely free. Zero client data leaves browser. Your files are processed strictly in local browser memory and never uploaded to our servers. The tool uses the EPA GHG Emission Factors Hub for all calculations, the same benchmark dataset professional ESG auditors use.
    What emission factors does this tool use?
    The calculator uses the EPA GHG Emission Factors Hub with eGRID2023 electricity subregion factors. EPA factors ensure precision. Global warming potentials follow the IPCC Fifth Assessment Report (AR5) 100-year standards: CO2 = 1, CH4 = 28, N2O = 265. The tool covers 67 stationary fuel types, 28 eGRID subregions, and 50+ waste materials.
    Can I use this for ESG reporting or investor disclosures?
    While our carbon footprint calculator follows EPA methodology, please review categorized transactions before submitting reports for regulatory disclosures. Audit-ready books protect ESG. Clean records attract investors. SlickBooks Managed Bookkeeping offers fully reconciled, auditable ESG reporting for venture-backed businesses.
    How accurate is AI-based carbon footprint estimation from bank data?
    The AI estimates activity quantities from transaction descriptions using regional commercial rate assumptions like $0.13 per kWh for electricity. Ditch manual carbon spreadsheets. For maximum accuracy, enter actual meter readings and fuel receipts directly. The calculator clearly flags estimated versus verified activity data.
