Impact, in a sustainability context, is the effect of behavior, performance, and/or outcomes, on the part of individuals or an organization, on the economy, the environment, society, stakeholders, or the organization itself. AccountAbility assists organizations in establishing processes to understand, measure, evaluate, and manage impacts that are credible, understandable, and replicable and that can be subject to external assurance. This includes, but is not limited to, evaluating the quantitative and qualitative impacts of strategies, programs, products, and services, and developing management recommendations to improve the future performance.
