ESG Funds: Verify Method, Exclusions and Fees
Verify the index or method actually followed, the published exclusions and the fees before choosing an ESG fund.
Published 2026-07-21
The word sustainable in a fund's name describes an intention; the documented method describes the product, and the two diverge often enough to justify the check. The fund facts and the prospectus reveal the real approach: sector exclusion, rating by a named agency with published thresholds, or impact financing — distinct philosophies the brochure happily blurs. The structural surprises read there too, an oil major well rated on governance able to remain in a rating-based index — a feature of the method rather than an anomaly. The ordinary columns complete the examination: fees compared with the equivalent broad fund, a typical gap of a few tenths to half a point, diversification narrowed by the exclusions, the manager's voting record and engagement report. The trade-off is then accepted knowingly, with an annual reminder, the published method able to change beneath the same name. This article guides the document reading and the questions that separate serious approaches from mere packaging.
Identify the method actually applied
The label says nothing about the method. Some funds exclude entire sectors, others keep the best-rated companies within each sector, and others still weight by a composite score without excluding anything. Those three approaches produce radically different portfolios, and only the prospectus or the tracked index's documentation reveals which one applies. A fund keeping the best in each sector holds oil companies, which surprises investors who assumed an exclusion. The reading takes twenty minutes and replaces an assumption with a verifiable fact.
Verify the exclusions and their thresholds
Exclusions almost always come with thresholds, expressed as a percentage of revenue derived from an activity. A ten percent threshold lets in a diversified company one of whose divisions carries out the targeted activity. Those thresholds appear in the methodology and can be compared across funds, where they vary considerably. The complete list of holdings, published regularly, is the final test: reading through it immediately reveals whether the portfolio matches what you thought you were buying. It is the most revealing exercise of the set, and the only one that does not rest on wording chosen by the product's manufacturer.
Look at how voting rights are exercised
Two strategies coexist: excluding problematic companies, or holding them to exert influence through voting and engagement. A fund following the second publishes its voting record and its engagements, consultable documents showing how it voted on shareholder resolutions. That record is more informative than any statement of intent, and its absence is itself information. Impact reports deserve the same critical reading: a document presenting only favourable indicators with no verifiable methodology belongs to communications rather than to accountability.
Compare fees and diversification
The fund is finally compared with a broad index fund on two measurable dimensions. Management fees, often twenty to fifty basis points higher, cost a considerable sum over thirty years, to be set against the value you place on the portfolio matching your convictions. Diversification next: a fund excluding several sectors concentrates the portfolio in the remaining ones, which changes its behaviour during sector rotations. Those two figures allow deciding knowingly rather than on the strength of the product's name. Neither figure appears in the marketing.
Quebec scenario: compare before confirming
The word sustainable appears in the name of the fund the branch proposes to a biologist in La Pocatière, and that is precisely her field: she decides to verify whether the label describes the contents. The fund facts document, then the prospectus, answer better than the brochure. The method first: the fund tracks an index that excludes certain sectors and weights the rest by environmental, social and governance scores supplied by a named agency; an exclusion-and-rating approach, neither better nor worse than another, but different from an impact fund financing targeted projects — a distinction the brochure blurred. The exclusions next, with their published thresholds: controversial weapons exit entirely, coal beyond a revenue percentage, but an oil major well rated on governance remains — the classic surprise of rating-based methods, which she prefers to know before rather than after. Voting rights and the engagement report complete the portrait: the manager publishes its votes at shareholder meetings, a transparency she appreciates. The columns of any fund remain: fees of 0.68% against 0.20% for the equivalent broad fund, and diversification slightly narrowed by the exclusions. She subscribes for half her monthly savings, in full knowledge of the trade: a real but imperfect filter, paid at 0.48 points — and an annual reminder to check that the published method has not changed beneath the same name.
Checklist
- Open the fund facts and the prospectus
- Identify the real method, exclusion, rating or impact
- Note the rating agency and published thresholds
- Check for composition surprises
- Read the voting record and engagement report
- Compare the fees with the equivalent broad fund
- Measure the diversification narrowed by exclusions
- Accept the trade-off knowingly
- Recheck the published method yearly
Frequently asked questions
How do I verify what an ESG fund actually does?
Through the fund facts and the prospectus, not the brochure: which index or method is actually followed — exclusion, rating or impact — by which rating agency, with which published thresholds. Two similarly named funds can apply opposite philosophies; only the documented method settles it.
Why can an oil major appear in a sustainable fund?
Because rating-based methods rank companies against each other, often within sectors: a company well rated on governance and practices can stay in the index despite its activity. That is not an anomaly but a feature of the method — better known before than after.
What surcharge and diversification trade-off should be accepted?
Compare the fees with the equivalent broad fund, the typical gap running from a few tenths to half a point, and check the diversification narrowed by the exclusions. The trade-off is accepted knowingly, with an annual reminder: the published method can change beneath the same name.
