    The BW Impact Investing Score offers a clear, quantitative framework for evaluating opportunities across five key components:

    1. Scale – Assess the breadth of impact and potential reach.
    2. Measurability – Track and quantify outcomes effectively over time.
    3. Intentionality – Ensure investments align with specific, impactful objectives.
    4. Additionality – Identify opportunities that generate transformative outcomes beyond what would occur otherwise.
    5. Depth – Evaluate the meaningfulness and transformative power of change.

    Developed by Barnett Waddingham, this approach simplifies complex qualitative data into an easy-to-understand metric. It enables investors to compare funds across diverse asset classes — from niche private equity solutions to global public equity opportunities — while balancing traditional financial metrics with meaningful social and environmental impact.
