Insurer Royal London has today launched a range of sustainable pension funds for its customers. The five funds offered by the company offer a choice of options of varying degrees of risk, and customers can invest their pension in the funds individually or in a portfolio. In total, the funds represent around £1.7bn in assets under management which will be handled by Royal London. Over the last five years, Royal London reckons the assets have delivered between four per cent and 12 per cent annualised return.
