Reporting impact

Impact calculator

Impact calculator

Since 2016, the WHEB investment team has sought to quantify the real-world positive impact associated with our portfolio. Our proprietary Impact Calculator illustrates what a given amount of money invested in the strategy contributes to, such as the renewable energy generated or clean water treated.

Ultimately, the impact is generated by the end users of those products and services. This calculator connects that real-world activity back to the investor who owns a stake in the companies delivering it.

The calculator can be used with both impact funds in our range.

Impact reports

Impact reports

Published annually, impact reports set out the specific sustainability challenges our portfolio is designed to address, the companies contributing to those solutions and quantified data on outcomes, including greenhouse gas reductions and progress towards sustainable business practices.

The reports also cover the investment team's theory of change: the causal path from investment activity to measurable real-world outcomes.

Impact reports demonstrate our continued leadership in the rapidly growing market for listed equity impact investing.
