The demand for green investments is growing rapidly, as more people decide they want their funds to be a force for good in the world. But that doesn’t mean investors have even a basic grasp of the scientific concepts involved.

Working with Anders Anderson of the Swedish House of Finance, Robinson surveyed Swedish households and found one thing that isn’t driving green investment is scientific knowledge – because most people failed a basic five question quiz about the environment.
