ESG Funds vs Catholic Funds: The Overlap and the Critical Differences

FaithScreener Research Team4/7/202612 min read

If you walk into most brokerage platforms and search for "socially responsible" or "sustainable" investment options, you'll find dozens of ESG funds. You might reasonably assume these ESG products would work for Catholic investors since they're applying some kind of moral screening to investment decisions. You would mostly be wrong.

ESG funds and Catholic funds look similar from a distance but make fundamentally different moral judgments. Understanding the differences matters because the wrong choice can leave you owning exactly the companies you wanted to avoid. Let's work through the overlap and the critical divergences.

What ESG actually stands for

ESG is an acronym for Environmental, Social, and Governance. It refers to a set of criteria that investors use to evaluate companies beyond pure financial metrics. The environmental component covers things like carbon emissions, resource use, and pollution. The social component covers labor practices, community relations, and consumer protection. The governance component covers executive compensation, board diversity, and corporate accountability.

ESG investing grew out of earlier "socially responsible investing" practices but became mainstream in the 2010s as institutional investors, regulators, and corporate leaders increasingly treated these factors as material to long-term financial performance. Today, ESG is a massive industry with trillions of dollars in assets under management and a significant footprint in the mutual fund and ETF landscape.

Major ESG fund providers include BlackRock, Vanguard, Fidelity, State Street, and most other large asset managers. Nearly every major fund family now offers ESG-screened options, and some have rebranded significant portions of their lineup as sustainable or ESG-aligned.

The philosophical foundations

Here's where the divergence starts. ESG investing is fundamentally a risk management framework. It assumes that companies with poor environmental, social, or governance practices face higher long-term risks, and that integrating these factors into investment decisions can reduce risk and potentially enhance returns. The moral framework is secondary to the financial framework.

Catholic investing is fundamentally a moral framework. It assumes that companies should be evaluated against Catholic social teaching because that teaching reflects truths about human dignity and the common good. The financial framework is secondary to the moral framework, though both matter.

This difference has practical implications. ESG funds generally don't exclude companies for moral reasons if those companies score well on ESG metrics. Catholic funds exclude companies for moral reasons even when those companies score well on financial or ESG metrics.

The philosophical difference also shows up in how each approach treats specific issues. ESG funds tend to treat issues like climate change and worker rights as primary concerns because those have clear financial materiality implications. Catholic funds treat life issues like abortion and contraception as primary concerns because those involve fundamental moral absolutes.

Where they overlap

Before exploring the differences, let's acknowledge the overlaps. ESG funds and Catholic funds often agree on several categories:

Climate change and environmental stewardship. Both approaches generally treat fossil fuel producers with poor climate plans as problematic. Both support renewable energy and energy transition. Catholic teaching via Laudato Si and ESG risk analysis both point toward similar environmental conclusions, even from different starting points.

Worker rights and fair labor. Both approaches treat serious labor violations and worker exploitation as concerns. Both support companies with strong labor practices. The emphasis differs (Catholic teaching on just wages versus ESG focus on financial risk from labor conflicts), but the practical conclusions often align.

Corporate governance. Both approaches value governance reforms, executive accountability, and board independence. Both support shareholder engagement on governance issues.

Weapons producers. Many ESG funds exclude controversial weapons (cluster munitions, landmines, chemical weapons) for reputational and risk reasons. Catholic funds exclude these categories for moral reasons. The practical result is similar exclusion.

Certain human rights violations. Both approaches generally exclude companies involved in modern slavery, forced labor, or similar severe abuses.

These overlaps mean that a portfolio built with ESG methodology will look somewhat similar to a portfolio built with Catholic methodology. They won't be identical, but there's meaningful convergence on many holdings.

Where they diverge

The critical differences come in several categories:

Abortion and contraception. This is the biggest divergence. ESG funds generally don't screen for abortion or contraception. Most ESG funds own major pharmaceutical companies that fail Catholic screening, including Johnson & Johnson (JNJ), Pfizer (PFE), Merck (MRK), and Bayer (BAYRY). A Catholic investor who buys an ESG fund likely ends up owning all of these. This alone disqualifies most ESG funds for strict Catholic investors.

Embryonic stem cell research. Similar to abortion and contraception, ESG funds don't typically screen for fetal cell line use or embryonic stem cell research. Companies with these activities pass ESG screens easily.

Pornography distribution. ESG funds vary on pornography exposure, but many don't explicitly screen for it. Some ESG funds own companies with adult entertainment connections that Catholic funds would exclude.

Corporate policies on life issues. ESG funds generally treat corporate support for abortion access or contraception coverage as positive (expanding healthcare access, supporting worker rights) rather than negative. Catholic funds treat the same policies as concerns.

LGBT-related corporate activism. This is an area where ESG and Catholic approaches often diverge significantly. ESG frameworks typically treat corporate support for LGBT causes as positive under the social and diversity pillars. Catholic teaching is more nuanced, holding that human dignity applies to LGBT individuals (Catechism paragraph 2358) while also maintaining specific teachings about sexuality and marriage. The practical result is that some Catholic investors screen differently than ESG funds on these issues.

The ratings agency problem

One of the reasons ESG and Catholic approaches diverge is that ESG depends heavily on ratings from firms like MSCI, Sustainalytics, and Morningstar. These ratings use specific methodologies that prioritize certain issues over others. The ratings shape which companies get included in ESG funds and how they're weighted.

The ratings have come in for significant criticism. Companies with clearly problematic practices sometimes receive high ESG ratings because the ratings methodology emphasizes disclosure rather than actual practice. A company that does a good job reporting its emissions might get a higher rating than a company that actually produces lower emissions but has less sophisticated reporting.

ESG ratings also vary significantly across providers. Research has shown that ratings for the same company can differ dramatically depending on which agency you use. This inconsistency makes the ESG framework less reliable as a moral screening tool, even from an ESG perspective.

Catholic screening doesn't depend on these ratings. Catholic fund managers do their own research on companies based on Catholic moral teaching, which they interpret through the USCCB guidelines and related documents. The screening might be less efficient (it requires more manual analysis) but it's more consistent with the underlying moral framework.

The greenwashing concern

ESG has become so popular that greenwashing is a real problem. Companies make environmental claims to attract ESG investor capital while continuing practices that contradict those claims. Funds market themselves as sustainable while owning portfolios that don't look meaningfully different from conventional funds.

The SEC has begun cracking down on some of the more egregious greenwashing, and there have been enforcement actions against funds that made misleading ESG claims. But the underlying problem persists: when moral or sustainability claims become marketing tools, the claims can become detached from the reality.

Catholic investing isn't immune to similar concerns. There are Catholic-branded funds that apply weaker screening than their marketing suggests. But the explicit theological foundation of Catholic investing makes pure greenwashing harder. If a fund claims to be Catholic but owns companies that clearly fail Catholic screening, the inconsistency is more visible than with vaguer ESG claims.

The Vanguard ESG funds

Let's look at a specific example: the Vanguard ESG U.S. Stock ETF (ESGV). This is one of the largest ESG ETFs, with tens of billions in assets and a cheap expense ratio. It's marketed as a way to get broad U.S. equity exposure with socially responsible screening.

What does ESGV actually exclude? The fund follows the FTSE US All Cap Choice Index, which excludes companies involved in:

Adult entertainment
Alcohol and tobacco
Weapons
Fossil fuels
Gambling
Nuclear power

What doesn't it exclude? Pharmaceutical companies involved in contraception and abortifacients, companies with corporate support for abortion access, companies with fetal cell line research connections, and various other categories that Catholic screening addresses.

Looking at ESGV's top holdings as of recent reports, you'll find Microsoft, Apple, Amazon, Alphabet, Meta, Tesla, and other major technology companies. Most of these fail Catholic screens for one reason or another (employee benefits, corporate activism, content policies, etc.). ESGV is not a Catholic fund.

This doesn't mean ESGV is bad. For investors who share its specific moral framework, it's a reasonable choice. But it's not Catholic investing, even though it's often marketed as "socially responsible."

The iShares MSCI KLD 400

Another common ESG option is the iShares MSCI KLD 400 Social ETF (DSI). This fund tracks the MSCI KLD 400 Social Index, which includes 400 companies that meet certain ESG criteria.

DSI's screening includes exclusions for:

Controversial weapons
Tobacco
Thermal coal
Oil sands
Nuclear power
Firearms

But again, it doesn't screen for contraception, abortifacients, corporate abortion policies, or fetal cell line use. The fund owns major pharmaceutical companies that fail Catholic screening. For Catholic investors, DSI is closer to Catholic funds than some ESG alternatives, but it's still not a substitute for actual Catholic screening.

The Catholic alternative

If you want Catholic-aligned investing, you need to use actual Catholic funds rather than ESG substitutes. Your options include:

Ave Maria Mutual Funds (AVMNX and related funds). Strict screening with emphasis on life issues.

Knights of Columbus Asset Management funds. Balanced approach with engagement focus.

Catholic Responsible Investments Equity Fund (CRIEX). Tries to track broader market benchmarks while applying Catholic screening.

LKCM Aquinas Funds. Catholic-screened mutual funds with a focus on consistency with Catholic teaching.

Global X S&P 500 Catholic Values ETF (CATH). An ETF that applies Catholic screening to the S&P 500.

These are the main options. Each has different methodologies, fees, and performance characteristics. None is perfect, but all do actual Catholic screening rather than ESG screening with Catholic marketing.

The hybrid question

Can you use ESG funds as part of a Catholic investment approach? There are a few arguments for this:

ESG funds are cheaper than Catholic funds. Expense ratios for ESG ETFs are often 0.1 to 0.2 percent versus 0.85 to 1.25 percent for Catholic mutual funds. Over long periods, the fee difference compounds significantly.

ESG funds are more widely available. They're on every brokerage platform and can be held in most retirement accounts.

ESG funds provide some overlap with Catholic concerns on environmental and governance issues.

Against these arguments: ESG funds include companies that fail Catholic screens, and owning them is inconsistent with Catholic teaching on moral cooperation. The cost savings don't justify the moral compromise for investors who take the USCCB guidelines seriously.

A practical compromise some Catholic investors use: build a core portfolio of Catholic-screened funds for the equity allocation that matters most, use ESG funds for specific niches where Catholic options don't exist, and supplement with individual stocks to fill gaps. This isn't ideal but it can work.

The theological stakes

The difference between ESG and Catholic investing reflects a deeper difference in how each approach thinks about moral knowledge. ESG tends to treat moral questions as a matter of negotiation among stakeholders with different interests and values. What counts as "good" depends on who's asking and for what purpose.

Catholic moral teaching holds that there are moral truths accessible through reason and revelation that don't depend on stakeholder negotiation. Abortion is wrong regardless of whether it's popular or profitable. Contraception conflicts with natural law regardless of whether it's widely practiced. These aren't matters of preference; they're claims about reality.

This difference isn't just philosophical. It affects actual portfolio decisions. ESG funds reflect the moral consensus of the investor community, which shifts over time and varies by region. Catholic funds reflect the moral teaching of the Catholic Church, which has continuity across centuries and cultures.

The Catechism paragraph 1954 addresses natural law directly: "Man participates in the wisdom and goodness of the Creator who gives him mastery over his acts and the ability to govern himself with a view to the true and the good. The natural law expresses the original moral sense which enables man to discern by reason the good and the evil, the truth and the lie."

When Catholic investors screen out companies for reasons that ESG doesn't recognize, they're implicitly accepting this natural law framework. They're saying that moral truths exist independently of investor consensus and that investment decisions should reflect those truths even when inconvenient.

The bottom line

ESG funds aren't Catholic funds. They share some concerns, but they operate from different moral frameworks and reach different conclusions on important issues. If you want Catholic-aligned investing, you need Catholic funds or custom portfolios built with Catholic screening, not ESG products with vague sustainability claims.

The difference matters most on life issues, which are foundational to Catholic moral teaching but peripheral to ESG frameworks. If you own an ESG fund, you almost certainly own pharmaceutical companies that produce contraceptives and have abortion-related corporate policies. That might be fine for ESG investors; it's not fine for Catholic investors.

Understand what you own. Read the holdings of any fund you consider for Catholic purposes. Verify that the screening actually addresses the categories you care about. Don't rely on marketing labels that might not reflect actual practices. And when in doubt, choose funds with explicit Catholic identity rather than general ESG products.

Your portfolio is either consistent with Catholic teaching or it's not. ESG funds can get you part of the way, but they can't take you all the way. The USCCB guidelines require the rest of the journey, which means actual Catholic investing rather than ESG substitutes.
