Hi
Apologies if this has been covered before, I've not found anything after a quick search.
I have a small amount (c£4K) in S&S ISA, LISA and SIPP with Hargreaves lansdown almost entirely in index funds on an accumulation basis. I put in circa £100-200 a month based on income fluctuations and expenses. It's the best I can do for now.
Looking ahead I want to invest in green energy, tech, and other futureproof investments. Reading about fossil fuel based market crashes got me thinking - what do you consider to be sustainable long term investments?
