What Does NerdWallet's 'Best ESG Funds for 2026' List Measure?

NerdWallet published a 2026 list titled "14 Best-Performing and Cheap ESG Funds," grouping funds that screen for environmental, social and governance factors alongside two separate metrics: historical returns and cost, according to the original report. The outlet did not make its fund-by-fund figures available for independent review in the version examined here, so this explainer focuses on how such rankings are typically built and what a reader should check before acting on them.

What does 'cheap' mean for an ESG fund?

In fund rankings, "cheap" almost always refers to the expense ratio — the annual fee a fund charges, expressed as a percentage of assets under management. A lower expense ratio means more of a fund's gross return reaches the investor's account each year. Index-tracking ESG funds, which hold a preset basket of screened companies rather than relying on a manager's stock picks, tend to carry lower expense ratios than actively managed ESG funds, a pattern that holds across most Morningstar fund categories.

What does 'best-performing' mean, and what's the catch?

"Best-performing" in these lists usually refers to trailing total returns over a fixed period, such as one, three or five years. The method matters: a ranking built on one-year returns can look very different from one built on five-year returns, because short lists are more sensitive to a single strong or weak stretch. Past performance also does not guarantee future results, a standard disclosure required on fund materials filed with the Securities and Exchange Commission.

A fund's past return and its future return are measured over different time periods by definition — the first already happened, the second has not.

How are ESG screens defined, and do they vary?

ESG labels are not standardized across the fund industry. One provider's ESG screen may exclude fossil-fuel producers outright; another may simply underweight them relative to a benchmark while still holding some energy stocks. Two funds both marketed as "ESG" can hold materially different companies, which is one reason performance and cost comparisons should be read fund-by-fund rather than category-by-category.

What should an investor verify before buying from a list like this?

Three checks are standard before acting on any "best of" fund list: read the fund's prospectus for its actual expense ratio and holdings, confirm the time period used for any performance figure, and compare the fund's ESG methodology against a reader's own priorities, since providers define the screen differently. Readers who already hold sector-specific funds, such as a utilities index fund, can use the same prospectus-and-expense-ratio check described in HTT's explainer on Vanguard's utilities ETF.

Where can readers see NerdWallet's full list?

The complete 2026 list of 14 funds, with NerdWallet's specific cost and return figures for each, is available at the originating article. Investors evaluating any entry on it should confirm the current expense ratio and performance window directly against the fund's prospectus before investing.
