How are the CO₂e savings calculated?

Each alternative fuel is compared at equal useful energy using well-to-wake (WtW) carbon-intensity factors from official sources (ADEME Base Carbone, JEC). The saving is the difference between your current fuel's WtW emissions and the alternative's, for the quantity you enter.

Which sectors and fuels are covered?

Road, maritime, aviation, non-road machinery, agriculture and industry — each with the certified alternatives relevant to it: HVO, B100, bio-LNG, bioCNG, sustainable aviation fuel (SAF), bio-methanol, biomethane, green hydrogen and more.

Are the results binding?

No. Values are illustrative only and depend on your specific situation (engine compatibility, blend limits, supply). For a tailored analysis, contact contact@myheeding.com.

Comparisons are energy-equivalent (same useful energy delivered) using well-to-wake carbon-intensity factors (ADEME / JEC). Figures are indicative; real-world savings depend on engine compatibility, blend limits and supply. Not every fuel is a drop-in replacement. Values shown are illustrative only — actual values depend on your specific situation. To learn more, contact contact@myheeding.com.
