Sustainable funds are a high-value but confusing part of green investing. This hub brings together The Planet Brief's explainers on ESG funds, sustainable ETFs, green bonds, FCA SDR labels, fund greenwashing, impact investing and platform selection.
Financial information only
This hub is for education only. It is not investment advice, a recommendation, or a personal financial promotion. Investments can rise and fall in value and sustainability labels do not remove financial risk.

What makes a fund sustainable?
A sustainable fund may exclude certain sectors, tilt toward companies with stronger ESG scores, follow a climate benchmark, invest in environmental themes, target measurable impact, or combine several approaches. These are not interchangeable. A broad ESG ETF can hold very different assets from a clean-energy thematic fund or a labelled impact strategy.
The useful question is not "is this fund green?" It is "what is the stated objective, what does the fund hold, what does it exclude, what benchmark does it follow, what evidence does it publish and what financial risks does it introduce?"
High-priority checks
- Read the fund objective before relying on the fund name.
- Check top holdings and sector exposure.
- Compare fees, diversification and concentration risk.
- Look for FCA SDR labels where they apply.
- Review exclusions and thresholds.
- Check whether impact claims are measured and reported.
- Review stewardship, voting and engagement evidence.
- Check total fees across the platform, fund and wrapper.
Bottom line
Sustainable funds can be useful, but fund names are not evidence. The quality of the claim depends on the objective, holdings, methodology, disclosures and stewardship record.
