Market Leakage
An increase in GHG emissions when a project changes the supply and demand equilibrium, causing other market actors to shift their activities. For example, if a large forest-conservation project reduces the local timber supply so that demand is unmet, this may increase prices and pressures on forests elsewhere. See "Leakage".

As the local supply of forest timber products declines, as a consequence of REDD+ project implementation, the value of forest timber products may increase which could incentivise harvesting outside of REDD+ project boundaries both nationally and internationally.
