ESG and Catholic Investing Are Not the Same Thing
The financial industry has a habit of packaging unlike things into the same box and calling it progress.
For the past decade, that box has been labeled ESG. Environmental, Social, and Governance criteria. The idea is that companies can and should be evaluated on factors beyond quarterly earnings such as how they treat their workers, what they pump into the atmosphere, whether their boardrooms are accountable. Major asset managers adopted the language and fund families built products around it. Institutions updated their mandates to include it.
Somewhere in that process, a conflation happened. Catholic investors, and sometimes their advisors, began treating ESG as a rough equivalent of faith-based investing. The screens sounded similar. The intentions seemed aligned. Both frameworks claimed to care about people and the planet.
They are not the same framework. They do not share the same foundation, the same methodology, or the same conclusions. And treating them as interchangeable produces portfolios that often violate the very values they claim to uphold.
Two Completely Different Questions
To understand why ESG and Catholic Socially Responsible Investing diverge, you have to start where each framework starts, with the question it is actually trying to answer.
ESG asks: What non-financial risks threaten this company's long-term financial performance?
That is a risk management question. The premise is that regulatory exposure, reputational damage, labor unrest, and environmental liability are material to investment returns and should therefore be measured and priced. ESG does not claim to be a moral framework. At its foundation, it is a financial risk tool that happens to evaluate social and environmental factors because those factors have become financially material.
Catholic Socially Responsible Investing asks a different question entirely: Does this company's activity respect the inviolable dignity of the human person and contribute to the common good?
That is a theological question. The premise is drawn not from financial risk theory but from Catholic Social Teaching, papal encyclicals, and the natural law tradition: there are things capital should not do regardless of whether doing them is profitable, and there are things capital should actively support regardless of whether the market rewards them in any given quarter.
These are different questions. They will sometimes produce similar answers. They will also produce sharply different ones and the places where they diverge matter enormously for anyone who believes the second question is the right one to ask.
The Scorecard Problem
ESG works through relative scoring. A company is evaluated across dozens of sub-metrics like carbon emissions per revenue dollar, board independence ratios, employee turnover rates, supply chain audit disclosures and these metrics are combined into a composite score. Companies are then ranked against their peers. A high score in one area can offset a low score in another.
There are several problems with this in practice.
The first is consistency. MSCI, Sustainalytics, Bloomberg, and Refinitiv (the four major ESG rating agencies) frequently assign radically different scores to the same company. A 2021 study published in The Review of Finance found that correlations between major ESG rating agencies averaged around 0.54, compared to 0.99 for credit ratings from Moody's and S&P. You are not measuring an objective property. You are measuring a methodological opinion, and the methodology keeps changing.
The second problem is offset logic. An electric vehicle manufacturer with documented forced labor in its cobalt supply chain can still receive a high ESG score because its environmental metrics are exceptional. The bad behavior does not disqualify the company but it is numerically diluted by performance in other categories. For investors who believe that certain conduct is simply off-limits regardless of how green the company's energy mix is, this arithmetic is not a feature but a flaw.
Catholic SRI enforces what the USCCB guidelines call hard exclusions. Companies directly involved in abortion, weapons of mass destruction, pornography, or human trafficking are not scored. They are excluded and no amount of excellent environmental disclosure changes that conclusion. The framework applies absolute criteria to a defined category of conduct before any weighted analysis begins.
This is not a minor methodological difference. It is a fundamental divergence in how moral responsibility is understood.
Where the "Social" in ESG Goes Wrong
The sharpest collision between secular ESG and Catholic investing happens in the middle letter: S.
Over the past several years, the social criteria embedded in major ESG frameworks have expanded to include metrics that directly conflict with Catholic teaching. Corporate policies funding abortion travel for employees (covering transportation and lodging for workers seeking elective abortions in other states) are increasingly treated as positive indicators within ESG social scoring. Companies receive credit for providing these benefits as part of comprehensive healthcare packages.
Under Catholic SRI guidelines, those same policies trigger exclusionary screens. The fact that a company scores highly on workforce gender representation or supply chain transparency does not resolve the problem. There is no offsetting calculation that makes participation in abortion services acceptable under the USCCB framework.
The same divergence appears in other areas. Some ESG frameworks have moved toward weighting corporate endorsement of specific political causes as positive governance signals. The line between measuring governance quality and enforcing ideological conformity has blurred in ways that have nothing to do with Catholic Social Teaching and frequently contradict it.
This is not an argument against every element of ESG analysis. Many of the metrics ESG frameworks measure like supply chain labor conditions, carbon transition planning, and board accountability structures overlap meaningfully with Catholic investing concerns. The problem is the package. When a Catholic investor buys into a generically labeled ESG fund, they are not buying a Catholic values screen. They are buying a financial risk tool built on a different set of anthropological assumptions, some of which directly conflict with their faith.
Integral Ecology vs. Carbon Reductionism
Pope Francis introduced the term integral ecology in Laudato Si' to capture something important about the Catholic approach to environmental stewardship. The human person is not separate from creation, but neither is creation intelligible without reference to the human person. Environmental concern and human dignity are inseparable. The care of the earth and the care of the poor are the same mission.
This is meaningfully different from how environmental criteria function in secular ESG.
Extreme versions of ESG environmental scoring have produced frameworks where reducing carbon emissions is treated as a terminal value, good in itself and worth pursuing at any human cost. Policies that price energy in ways that devastate the poorest communities. Agricultural restrictions that reduce food security in developing nations. Industrial transitions that eliminate livelihoods without adequate replacement. These outcomes can coexist with high environmental ESG scores because the scoring is not built around a human-centered evaluation.
Catholic environmental stewardship does not accept that trade-off. Laudato Si' is explicit: an ecology that treats human beings as the problem rather than the beneficiary of creation care has made a fundamental error. The Church is not anti-environment. It is anti-misanthropy and those are not the same position.
Why This Matters If You Don't Care About Either
Here is where the conversation becomes relevant to an investor who dismisses both frameworks and simply owns index funds.
When trillion-dollar asset managers allocate capital according to ESG scores, stock prices move. Companies that score well receive disproportionate inflows. Companies that score poorly face disproportionate outflows. These flows happen independently of revenue, earnings, or operational performance. A traditional investor holding a broad index fund is paying prices shaped by these non-financial flows whether they are aware of it or not.
Proxy voting is the second mechanism. When an investor owns shares through a mutual fund or ETF, the fund manager votes those shares at corporate annual meetings. Most retail investors have no idea how their fund manager votes or that their retirement assets are being used to vote on shareholder resolutions related to abortion funding, executive compensation tied to ESG targets, carbon emission caps, and digital content moderation policies. ESG-oriented fund managers tend to vote one way on these resolutions. Faith-based fund managers vote differently. The traditional investor's capital is being deployed in one direction or the other, without their input, every proxy season.
The legal and regulatory environment adds a third layer. Multiple states have passed legislation restricting the use of ESG criteria in state pension fund management, blacklisting financial institutions that apply ESG-driven divestment policies, and requiring fiduciary documentation that ESG decisions are financially justified. The SEC has moved to require climate disclosure standards. The resulting legal friction of lawsuits, compliance costs, fund restructuring, and political pressure creates systemic costs that every market participant absorbs, regardless of their personal position on ESG or faith-based investing.
The investor who claims to have no stake in this debate is already inside it.
The Stability Advantage
There is one practical difference between ESG and Catholic SRI that deserves specific attention for anyone managing money over a long time horizon: the stability of the criteria.
ESG scores change. Rating methodologies are revised. What counts as a positive social indicator in 2020 may be weighted differently in 2025. Regulatory changes in one country can alter how a company's environmental metrics are calculated globally. The framework is designed to be responsive, which means it is also designed to shift.
Catholic SRI criteria are anchored in sources that do not respond to quarterly cultural pressure. The Catechism of the Catholic Church does not get a methodology update when political winds shift. The USCCB guidelines are revised thoughtfully and deliberately, for example the 2021 update came thirty years after the original. Mensuram Bonam draws on two thousand years of developed moral theology.
For an institutional investor building a portfolio with a twenty-year horizon, or an individual planning for retirement, there is something meaningful about a framework whose core commitments are not subject to revision by a ratings committee. The criteria are debatable, not arbitrary.
Knowing Which Question You Are Answering
This is, ultimately, a question about intellectual honesty.
If what you want is a financial risk management tool that incorporates environmental and social data, ESG products exist that serve that purpose reasonably well, with the significant caveat that rating agency disagreement means you should understand the methodology behind whichever product you are using.
If what you want is a portfolio that reflects Catholic values, you need a framework built on Catholic values. ESG is not that framework. It was not built to be that framework, and calling it close enough produces portfolios that will, on a long enough timeline, include companies doing things that Catholic teaching clearly prohibits and exclude or underweight companies doing things it clearly supports.
The financial industry will continue to blur this line because blurring it is profitable. The same product can be sold to many more buyers if the label is broad enough to cover everyone.
The responsibility for knowing the difference belongs to the investor. More specifically, it belongs to the advisor sitting across from a Catholic client who deserves to know that the framework they think they are buying and the framework they are actually buying are not the same thing.
