More than three million British investors are looking at putting their money in ethical investments in the next 12 months.
New research from Brewin Dolphin Securities, the UK's largest portfolio manager, shows this trend to invest ethically is strongest among older Britons.
Some 12 per cent of investors over the age of 65 are considering putting their money into funds with morals, compared with the national average of seven per cent.
"This research confirms that there is a high level of interest amongst investors for opportunities to invest ethically and responsibly," said Charlotte Black, director of corporate affairs at Brewin Dolphin Securities.
And people choosing to link their money to their morals are not missing out on income either.
Figures from Co-operative Insurance show some ethical funds have outperformed UK stocks and most UK unit trusts over the last three years.
And this performance becomes all the more impressive when rises in the FTSE have been driven by sectors including defence and oil, which are excluded from the majority of ethical funds.
Internal to the UK, Londoners are most likely to put money into ethical investments.
Some 14 per cent of investors living in the capital are planning to put their money where their morals are in the next 12 moths.
By contrast investors in the East Midlands are the least moral, with just two per cent of the people in this region planning to put money into ethical funds.
