Activity-based emissions calculator

Multiply consistent activity units and a specified emission factor within the stated inventory boundary.

Units

M = A \times \mathrm{EF}

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Given

M = 850 \times 118 = 100{,}300

Symbol	Meaning	Unit
$M$	reported emissions on the factor basis	lb CO2e
$A$	energy activity	MMBtu
$\mathrm{EF}$	specified emission factor	lb CO2e/MMBtu

Symbol	Meaning	Unit
$M$	reported emissions on the factor basis	kg CO2e
$A$	energy activity	GJ
$\mathrm{EF}$	specified emission factor	kg CO2e/GJ

Results are estimates for study and screening. Check the inputs, units and assumptions before you use them for design, billing or contract decisions.
