What ethical and ESG investing means

Ethical and ESG (environmental, social, governance) investing aligns your money with your values — avoiding harmful industries and/or favouring responsible companies. The best approach matches your specific values with genuinely sustainable funds, while keeping costs and diversification sensible. Watch for 'greenwashing' — funds that claim more than they deliver.

1. ESG / sustainable funds

Funds that screen or weight investments on ESG criteria. Best for most ethical investors — a diversified, low-cost ESG fund is a simple core holding. Check what the fund actually screens for.

2. Ethical exclusion funds

Avoid specific sectors (tobacco, weapons, fossil fuels). Best for those who want to exclude particular industries from their portfolio.

3. Impact and thematic funds

Target measurable positive impact (clean energy, social housing) or themes. Best for investors wanting their money to actively support specific causes — often higher risk, so diversify.

4. Ethical ISAs and pensions

Hold ethical funds within a stocks & shares ISA or pension for tax efficiency. Best for aligning your main tax-efficient savings with your values — many providers now offer ESG options.

Avoiding greenwashing

  • Check what the fund actually screens for or invests in
  • Look at the top holdings, not just the label
  • Consider recognised sustainability ratings and disclosures
  • Keep costs and diversification sensible
