Impact Measurement & Management is essential to everything we do
Impact Measurement and Management (IMM) is the ongoing practice of measuring and improving our impact, so that we can reduce the negative and maximize the positive.
Standardization and clarity of IMM practices is critical for impact investing to grow and we are proud to align with and contribute to industry-leading best practices for IMM.
For an in-depth look into our IMM practices, check out our most recent Impact Management Disclosure and our Impact Report.

Operating Principles for Impact Management
The Impact Principles created a market standard by which all signatories must measure, monitor, verify, and disclose their impact. Learn more about the Impact Principles on our blog, read our Impact Disclosure Statement, and check out this short video on how our practices align with Principle #4: Assess the expected impact of each investment, based on a systematic approach.
