Defining Additionality
The professional lexicon of climate policy has an air of maturity. Melding climate science terminology, esoteric domain concepts, and countless three letter acronyms (TLAs), carbon wonks are known to dialogue in an inaccessible jargon so rich it may, to the uninitiated, appear to border on another language. Yes, by this hollow measure, climate policy would seem to have the trappings of more established professional fields. Yet, a cursory look at the definitions associated with carbon’s work bank rather nakedly underscores our discipline’s immaturity. Nowhere in climate policy is language and definition more confused than the concept of additionality.
