Primary GHG Effects

Definition

A Primary GHG Effect is the intended change caused by a project activity in GHG emissions, removals, or storage associated with a GHG source or sink.

Each project activity will generally have only one primary effect. The primary effect is defined as a change relative to Baseline Emissions. which are determined using a suitable baseline methodology. Primary effects are identified for each project activity.

The GHG Project Protocol classifies six generic types of Primary GHG Effects of a GHG Project Activity:

• Reduction in combustion emissions from generating grid-connected electricity.
• Reduction in combustion emissions from generating energy or off-grid electricity, or from flaring.
• Reductions in industrial process emissions from a change in industrial activities or management practices.
• Reductions in fugitive emissions.
• Reductions in waste emissions.
• Increased storage or removals of CO₂ by biological processes.
