Cloud Carbon — Why Spend Equals Emissions
Data centres consume 1–2% of global electricity. Cloud providers publish average emission factors per dollar of spend. Billing spend is the most practical proxy for SMEs without server-level metering.

Remote Work & Commute Emissions
The average US commuter emits ~0.393 kg CO₂ per mile driven (EPA 2025). Eliminating 245 commute days per year via remote work is often the single largest CO₂ lever for office-based SMEs.
Our Data Sources
Cloud factors are from the Cloud Carbon Footprint open-source project (2024 averages). Commute factors use EPA 2025 average passenger vehicle emissions. Both are reviewed annually.
From Estimate to ESG Report
For GHG Protocol Scope 3 reporting, document the methodology version, factor source, and calculation date shown in the Methodology panel. Supplement with vendor-provided Scope 3 data for audited filings.
Frequently Asked Questions
Is my billing data or employee count stored anywhere?
No. All calculations happen entirely in your browser using JavaScript. No data is ever sent to our servers, stored in a database, or shared with third parties.
How accurate are the carbon estimates?
The estimates use industry-average emission factors from the Cloud Carbon Footprint project (2024) and EPA 2025 data. They are suitable for directional ESG reporting, not for ISO 14064-certified accounting.
Can I use these results in a sustainability report?
Yes, with the disclosure that results are browser-based estimates using Cloud Carbon Footprint and EPA methodology. For audited GHG reports, supplement with vendor-issued Scope 3 data.
Does the tool work offline?
Yes. Once the page has loaded, all calculations run locally in your browser with no internet connection required. Eco-Metrics is fully offline-capable.
