What Is Impact Investing?

Impact investing has moved from the margins to a serious allocation for many wealthy families, particularly the next generation. But it is routinely confused with ESG and with philanthropy, and the distinctions matter.

What it is

Impact investing is investing capital with the explicit intention of generating a measurable, positive social or environmental impact alongside a financial return. Two features define it: intentionality, the impact is a deliberate goal, not an accidental by-product, and measurement, the impact is actually tracked and reported, not merely claimed. Typical areas include clean energy, affordable housing, financial inclusion, healthcare and education, and businesses serving underserved communities.

How it differs from ESG and philanthropy

The three are often blurred but sit in distinct places:

• ESG (environmental, social, governance) is a risk and quality lens applied within ordinary investing. It screens or scores companies on ESG factors to build better conventional portfolios, and asks how a company behaves. It is about avoiding harm and managing risk.
• Impact investing goes a step further and asks what change the capital causes. It actively seeks a specific, measurable outcome, not merely the absence of harm.
• Philanthropy gives money away for good, expecting no financial return. Impact investing keeps the capital invested and expects it back, with a return.

In short: philanthropy spends capital for good; ESG invests capital more carefully; impact investing invests capital to cause a defined good and earn a return.

The returns question

The most common myth is that impact must mean sacrificing returns. In reality, impact investments span a spectrum:

• Market-rate impact: aiming for fully competitive returns alongside impact, on the view that solving real problems is profitable.
• Concessionary impact: deliberately accepting lower returns in exchange for greater or harder-to-fund impact.

Neither is right or wrong; the family chooses where on the spectrum to sit, deal by deal.

Why it matters for families

Impact investing has become a powerful tool for family cohesion and purpose, especially for engaging the next generation, who often want the family's capital to reflect its values, not just grow. Aligning a portion of the portfolio with the family's mission can turn abstract wealth into shared, meaningful work, complementing the family's philanthropy and strengthening its governance. The discipline is to hold impact investments to both standards honestly: real, measured impact, and a clear-eyed view of the return.
