Just two years ago, there were 50 ethical funds in the UK. Today there are almost 90. Just three years ago, assets under management in ethical funds totalled £4.5bn. Today, they total almost £8bn. And as climate change not only takes centre stage in British politics, but also seeps ever deeper into the conscience of the UK public, these numbers will continue to rise exponentially. So while ethical investing remains a niche sector for now, it will soon break into the mainstream.

Inevitably, therefore, more and more fund management houses will feel they have little choice but to launch an ethical product. The problem is, many simply don't have the experience, or knowledge, to do so.
