Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Use a factor for the actual fuel and desired boundary (combustion or lifecycle). This is CO₂, not automatically all greenhouse gases. Scenario calculation using your supplied factors. Defaults are illustrative inputs, not verified regional or product-specific measurements.
Example Calculation
- Fuel consumed: 100 L
- Emission factor: 2.3 kg CO₂/L
100 L at an entered 2.3 kg CO₂/L gives 230 kg CO₂.
Frequently asked questions
How do I use this calculator?
Enter fuel consumed, emission factor. The result updates automatically. Use Reset to restore the example values.
What method does it use?
CO₂=fuel volume × compatible emission factor.. Use a factor for the actual fuel and desired boundary (combustion or lifecycle). This is CO₂, not automatically all greenhouse gases. Scenario calculation using your supplied factors. Defaults are illustrative inputs, not verified regional or product-specific measurements.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
