Have you ever heard about #additionality, besides 1+1 =2?
In simple terms, the concept of additionality is the property of activity being additional. In fact, this basic term is also applicable when talking about the environmental crediting markets!
(See Impact #5 On Carbon Credits)
According to the Carbon Offset Guide, “GHG reductions are additional if they would not have occurred in the absence of a market for offset credits”.
In other words, if there is a presence of GHG reductions without selling carbon offset credits, then they are not considered additional.
