Each week BusinessDesk and the NZ Herald’s Cooking the Books podcast tackles a different money problem. Today, it’s how "impact investing" is taking over the ethical space. Hosted by Frances Cook.

This podcast is brought to you by Milford Asset Management.

Investing with an ethical and sustainable mindset is changing and it’s all down to figuring out what might actually make a difference. 

For the past few years, sin was not in. 

Shares deemed to be "sin stocks" were often kicked out of ethical funds, with those investors wanting nothing to do with companies whose products weren’t making the world a better place. 

But it hasn’t changed much, so that tactic is now evolving. 

More and more investors are now interested in the idea of companies operating in the grey zone, to push them towards doing better. 

For the latest podcast, I talked to Milford Asset Management's head of sustainable investing Frances Sweetman.
