We provide advice on incorporating sustainability into corporate strategies, and advise on impact reporting using the External Rate of Return.

External Rate of Return

Time Partners created the External Rate of Return with the London School of Economics to measure a company or investment’s purpose and wider impact on society, the economy, and the environment. Promoting radical transparency, the ERR encourages companies to track and report the total external outcomes of their activities and act accountably.

The ERR is designed to be a simple, holistic concept allowing companies, investors and third parties to report their activities comprehensively and transparently across a range of parameters.
