| + | There are two types of GHG effects |
− | A primary 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.

− | == Secondary Effects ==
| |
− | A secondary effect is an ''unintended change'' caused by a project activity in GHG emissions, removals, or storage associated with a GHG source or sink. Secondary effects are typically small relative to a project activity’s primary effect. In some cases, however, they may undermine or negate the primary effect. Secondary effects are classified into two categories:
| |
− | * One-time effects: Changes in GHG emissions associated with the construction, installation, and establishment or the decommissioning and termination of the project activity.
| |
− | * Upstream and downstream effects: Recurring changes in GHG emissions associated with inputs to the project activity (upstream) or products from the project activity (downstream), relative to baseline emissions. | |
− | | |
− | Some upstream and downstream effects may involve market responses to the changes in supply and/or demand for project activity inputs or products. Only significant secondary effects, however, need to be monitored and quantified under the [[GHG Project Protocol]]. Whether a secondary effect is considered significant depends on its magnitude relative to its associated primary effect and on circumstances surrounding the associated project activity.
