Disclaimer

The calculators on www.carbonnest.org produce estimates. They multiply the values you enter by published emission or conversion factors. Real-world emissions depend on many variables — your specific equipment, local grid mix, occupancy, weather, and more — so treat every result as an approximation.

We use factors from published sources including the UK Government, US EPA, and Ember data presented through Our World in Data. Factors vary by region, reporting year, and calculation boundary; each calculator identifies the source and assumptions it uses.

Nothing on this site constitutes professional, financial, legal, or engineering advice. For decisions with financial or regulatory consequences — such as installing solar, buying a vehicle, or reporting emissions — consult a qualified professional and verify figures independently.

The site displays advertising and may link to external resources. We do not endorse and are not responsible for third-party content or products.
