Additionality
An attribute of impact, requiring an investor or company's thoughtful and reasonable articulation of the degree to which its support causes a change in an outcome that would have not otherwise happened (in a no-intervention or business as usual baseline scenario).
Financial Additionality: Impact that would not have happened without an investment by a fund with a mandate that deviates from market standard.
Value Add Additionality: Impact that would not have happened without unique non-financial value an investor provides to a portfolio company.
Performance Additionality: Impact that would not have happened without the company creating or improving a solution with a unit impact that is superior to alternatives.
Adoption Additionality: Impact that would not have happened (in the same timeframe) but for the increased adoption of a solution.
