I recently put some savings into bonds using the UK’s Abundance platform which offers various methods of sustainable investment.
At that point, I contacted Abundance to ask them a few questions which I hadn’t found answers to on their website, and this is what they replied, which I’ll quote it verbatim since it’s all straight-forward stuff as far as sustainable investment goes.
So far they had 2 offerings where I could invest at the start. I wrote a ‘how-to’ guide about putting money into an account and judging the risks involved with the investments they offer, here: Green Investing with an Abundance ISA
