How to invest in improving our world

A reverse vending machine that recycles plastics, an alternative to cotton that is less devastating for the environment, and clever software to help farmers grow more with less effort.

Those are just three of the things that companies held by investment trust Impax Environmental Markets produce.  

If you thought investing to make the world better, was all about ethical funds that just avoid tobacco, arms and oil, then think again. 

It is possible to invest your money with companies that are trying to answer the questions that the world is throwing at us, improving the environment and making the most of scarce resources – and make a profit from that.

On the Investing Show, Jon Forster, of Impax Environmental Markets, joins us to explain what this interesting investment trust does and what he has learnt in almost two decades of investing this way, through both boom and bust.

The trust focuses on energy, water, waste and sustainable food and within those categories are some companies doing fascinating things.
