Relative emissions reduction calculator

Compare emissions on the same period and boundary; a reduction percentage is not an absolute avoided mass.

Units

R = \frac{M_{\text{base}} - M_{\text{new}}}{M_{\text{base}}} \times 100

Calculator

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

Given

R = \frac{480{,}000 - 360{,}000}{480{,}000} \times 100 = 25

Symbol	Meaning	Unit
$R$	relative emissions reduction	%
$M_{\text{base}}$	baseline emissions on matched boundary	lb CO2e
$M_{\text{new}}$	new emissions on matched boundary	lb CO2e

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