Terminology Update

[S4mmyb]

In a desire to create consistency across projects we want to update the create a standardized taxonomy / ontology to refer to the different descriptive terms we use in credit class, project, and credit batch metadata. The Regen Registry team will start working on creating this taxonomy. Until then, I'm proposing a few updates to certain terms based on the newly published Lexicon Iconography. This issue just tracks the proposed list of new terms and their definitions. The description will be actively updated as I come across terms in our existing metadata sets I think are more appropriately labeled/defined in the lexicon iconography project.

Old Term	New Term	New Term Definition
Additionality Approach	Additionality Assessment	Assessing whether a carbon project’s emission reductions or removals are additional to what would have occurred in the absence of the project to establish eligibility in carbon markets.
Leakage Approach	Leakage Assessment	Evaluating and addressing potential leakage, which refers to the unintended increase in emissions in one location or sector due to the implementation of a mitigation activity in another location or sector
