Quantifying GHG Reductions

Definition

Quantifying GHG Reductions is a procedure for compiling and reporting an aggregate GHG reduction from a GHG Project. The following is according to

• The standard reporting unit is in tonnes of CO2 Equivalent, denoted as (t CO₂eq)
• The GHG reduction is the sum of annual GHG Project Activity reductions PA_t for the time horizon of the project

$\mbox{GHG Reduction} = \sum_t \mbox{PA}_t$

Project Activity Reduction

$\mbox{PA} = \mbox{Primary Effects} + \mbox{Secondary Effects}$

Annual Quantification of GHG Reduction

$\mbox{R} = \mbox{BE} -\mbox{PE}$

Where:

• $\mbox{R}$ are the Annual GHG reductions for the entire GHG project
• $\mbox{BE}$ are the total annual baseline emissions for all the GHG project's primary effects
• $\mbox{PE}$ Total annual GHG project emissions

Annual Baseline Emissions

$\begin{align} \mbox{BE} &= [\mbox{Process Emissions}] + [\mbox{Combustion Emissions}] \\ & = [C_y \mbox{CF}_b \mbox{EF}_p ] + [C_y \mbox{CF}_b E \mbox{EF}_c] \end{align}$

Project Emissions

$\begin{align} \mbox{PE} &= [\mbox{Process Emissions}] + [\mbox{Combustion Emissions}] \\ & = [C_y \mbox{CF}_p \mbox{EF}_p ] + [F_y \mbox{CF}_b \mbox{EC}_c \mbox{EF}_c] \end{align}$
