There are so many places I can't wait to scuba dive but one that fascinates me is in Isla Mujeres off Mexico's Yucatan Peninsula. The dive is only 33 feet down so this is an easy trip down and up but what is down there is fascinating. Divers will see six men kneeling on the ocean floor, their heads buried in the sand, briefcases by their sides, and butts pointing skyward. As an added touch, there are cell phones on top of the briefcases.
Created by Jason deCaires Taylor in 2012, Los Banqueros (The Bankers, and interestingly originally called, "The Politicians") calls attention urgent environmental and societal concerns. Should we ignore the risk of climate change by burying our heads in the sand and continuing to ignore it until we are underwater?
It is against that backdrop that I read the latest anti-climate-change action by the current administration. As I think I understand it, the EPA has rescinded the 2009 “Endangerment Finding,” a scientific and legal determination that greenhouse gases threaten public health and welfare. That finding has been the legal foundation for most U.S. climate regulations under the Clean Air Act, including emissions standards for vehicles, power plants, and industrial sources.
My Cliff notes version is:
The decision removes the EPA’s primary legal authority to regulate greenhouse-gas emissions at the federal level.
It eliminates or undermines existing emissions rules, particularly for vehicles, and could extend to power plants and oil-and-gas operations.
The administration characterizes the move as a major deregulatory effort intended to reduce costs and regulatory burdens.
States, environmental groups, and attorneys generals are expected to challenge the action in court, creating prolonged regulatory uncertainty.
If courts ultimately uphold the repeal, future administrations may need years to rebuild the legal basis for climate regulation.
In short: this is less about climate science itself and more about removing the federal regulatory framework governing greenhouse-gas emissions — with the outcome still uncertain due to likely litigation. Regardless of where you land in the political landscape, remember this, Mother Nature always bats last.
What this could mean for 401(k) investments
Turning to my favorite topic (401k plans!), here are some short-term market effects, long-term structural considerations, and fiduciary implications.
1. Short-term investment implications
If deregulation holds, it is generally supportive of fossil-fuel-intensive sectors, at least cyclically. These sectors include oil & gas producers, pipeline and midstream infrastructure, traditional utilities, internal-combustion auto supply chains, and industrial manufacturing
Reduced compliance costs and slower energy-transition mandates can improve margins and capital-spending in these industries.
At the same time, clean-energy and ESG-tilted investments could face sentiment headwinds, especially those reliant on regulatory incentives or emissions standards.
However, markets often price policy changes quickly — and the legal uncertainty may limit sustained valuation shifts.
2. Long-term investment implications
For plan sponsors thinking in decades (appropriate for retirement plans), the impact is less straightforward.
Three structural forces still matter:
A. Global policy momentum U.S. federal policy is only one driver. Europe, many states (especially California), and large corporations continue decarbonization efforts regardless of federal changes. As mentioned in a previous article, my home owner's insurance company dropped my policy with a two-day notice leaving me to scramble to find a more expensive and less comprehensive policy. The reason for me (and others) being dropped? The insurance company is facing too much climate change risk in the form of wildfires. Investment bank Lazard's latest annual report on renewables concludes, "that renewables are the most cost-competitive form of generation, even without subsidies"
B. Energy transition economics Renewables, electrification, and grid modernization are increasingly driven by cost competitiveness, not just regulation.
C. Regulatory whiplash risk Climate policy is becoming administration-dependent, increasing volatility in transition-related sectors.
From an asset-allocation perspective, this tends to argue for diversification across energy systems rather than binary ESG vs. fossil-fuel positioning.
3. Implications for ESG and fossil-fuel-screened options
Funds with fossil-fuel exposure may see near-term relative performance support. These same funds could face long-term transition risk depending on global policy and technology trends.
On the flip side, fossil-fuel-screened or ESG funds may experience short-term tracking error vs. broad indexes. These funds could still align with participant demand trends and global capital-market direction.
The point I would make is that the policy change does not eliminate climate risk as a financial risk factor — it mainly changes the U.S. regulatory pathway. The risk of climate change might still be described as pecuniary.
4. Fiduciary perspective for plan sponsors
From a prudent-fiduciary standpoint, this development reinforces that climate policy risk is political-cycle risk. In the same vein, ESG considerations remain economically and participant-preference driven. Investment menus should avoid policy-dependent concentration risk.
A defensible stance for committees could be to maintain diversified core options, avoiding making menu changes based solely on federal policy shifts. As always, document monitoring of climate-related financial risk (pecuniary risks) and document all investment decisions. This approach aligns with ERISA’s process-based fiduciary framework.
The Parting Glass
This is a major regulatory headline but not a structural investment thesis change. Also, burying one's head in the sand and ignoring a problem does not make the problem go away.
The energy transition is driven by technology cost curves, global capital flows, state-level policy, and corporate decarbonization commitments.
Federal deregulation can slow the transition at the margin, but it likely cannot reverse it.
