Leakage

Leakage refers to a situation where an activity within the project boundary triggers an emission on lands outside of the project boundary. Two common forms are activity-shifting leakage and market leakage. Activity-shifting leakage occurs when activities inside the project boundary (e.g. land conversion) relocate outside of the boundary. Market leakage occurs when project activities affect an established market for goods (e.g. farmed products) and causes the substitution or replacement of those goods elsewhere. (TNC)
