End Polluter Welfare for Enhanced Oil Recovery Act of 2026
Summary
S.4222, the End Polluter Welfare for Enhanced Oil Recovery Act of 2026, is an early-stage Senate bill that would eliminate tax credits for CO2-based enhanced oil recovery for new projects. With 5 cosponsors and referral to the Finance Committee, passage is highly uncertain and years away. Direct financial impact on ExxonMobil and Chevron is negligible in the near term given grandfathering of existing projects and the bill's early legislative stage.

Key Takeaways
- 1.S.4222 is early-stage legislation with 5 cosponsors and no committee action — near-zero probability of passage in this Congress
- 2.Existing CO2-EOR projects are grandfathered; only new projects lose tax credits, limiting immediate dollar impact
- 3.ExxonMobil and Chevron see negligible near-term revenue risk, with estimated annual impact under $50M combined if enacted
- 4.Companion bill HR8108 exists in House but faces identical Republican-controlled chamber headwinds
Market Implications
The market has correctly priced zero risk from this bill. ExxonMobil at $155.19 has rallied 4.21% in the last week while Chevron at $193.42 has gained 4.43%, moves driven by crude oil fundamentals and sector rotation, not legislative risk. Both stocks remain well within their 52-week ranges ($101-176 for XOM, $134-215 for CVX). There is no actionable trading signal from S.4222 at this stage. Investors should ignore this bill until it demonstrates committee traction, which is unlikely before 2027.
Full Analysis
On March 26, 2026, Senator Merkley introduced S.4222, the End Polluter Welfare for Enhanced Oil Recovery Act of 2026. The bill was read twice and referred to the Committee on Finance. It has 5 cosponsors (Van Hollen, Markey, Booker, Sanders, Warren) and an identical companion bill HR8108 in the House. The legislation is at the very beginning of the legislative process.
The bill has no funding mechanism — it is a tax credit elimination bill. It removes two tax preferences: (1) the ability for new CO2-EOR facilities built after enactment to claim the 45Q carbon oxide sequestration credit for CO2 used as a tertiary injectant, and (2) full repeal of Section 43 of the Internal Revenue Code, which provides a 15% credit for qualified enhanced oil recovery costs. Existing EOR projects are grandfathered — only facilities constructed after enactment lose access.
The structural losers are oil majors with CO2-EOR operations such as ExxonMobil ($XOM) and Chevron. However, the impact is small for two reasons. First, existing projects are unaffected, meaning the vast majority of current EOR production capacity retains its tax treatment. Second, new EOR investment is a small fraction of these companies' upstream capex. Independent EOR operators like Denbury (acquired by Exxon in 2023) are now subsumed within $XOM.
Real market data shows ExxonMobil at $155.19 (down 8.53% over 30 days but up 4.21% over 7 days) and Chevron at $193.42 (down 6.52% over 30 days, up 4.43% over 7 days). These movements reflect broader oil price dynamics and Q1 earnings sentiment, not this bill. The 7-day rallies of ~4% for both names are inconsistent with any bearish legislative overhang, confirming the market views this bill as noise.
The timeline is extremely long: committee markup, floor vote in Senate, House passage via companion bill or stand-alone, differences resolved in conference, and presidential signature. With Democrats in the minority in the 119th Congress, this bill has no realistic path to enactment before 2027 at the earliest, and likely never without a change in congressional control.

What the bill does
Elimination of Section 45Q tertiary injectant credit for new CO2-EOR facilities and repeal of Section 43 enhanced oil recovery credit
Who must act
Oil producers using CO2 for enhanced oil recovery in new projects built after enactment
What happens
Loss of up to ~$15/tonne 45Q credit for CO2 used as tertiary injectant and loss of 15% Section 43 EOR credit on qualified costs for new projects
Stock impact
ExxonMobil operates CO2-EOR projects in West Texas and Wyoming (e.g., LaBarge, Permian Basin CO2 flood). New project economics face ~$2-5/BOE margin headwind, but existing projects are grandfathered. Impact limited to new greenfield EOR capex decisions. Exxon's Q4 2025 upstream capex was ~$4.5B; EOR-specific new investment is a small fraction.

Further Adjusting the Tariff Regimes for Imports of Aluminum, Steel, and Copper into the United States
This proclamation modifies existing Section 232 tariffs on aluminum, steel, and copper imports by expanding the list of derivative products eligible for a reduced 15% duty to include agricultural equipment and residential HVAC systems, temporarily reducing tariffs on mobile industrial equipment, adding aluminum lithographic plates and steel racks to the derivative tariff coverage, and lowering the threshold for products to qualify as made 'entirely' from American metals from 95% to 85%.
Approving Critical Position Pay Authority for National Security Investment Workforce
This memorandum authorizes the Office of Personnel Management to allocate up to 400 critical positions with pay up to $400,000 to recruit specialized talent for national security investment programs, focusing on critical minerals, advanced materials, and strategic supply chains. It directs OPM and OMB to oversee allocation and ensure pay is used only to recruit or retain exceptionally qualified individuals. The action aims to accelerate domestic mineral production and reduce foreign dependence.
Removing Unnecessary and Counterproductive Restrictions on Access to Federal Lands
This executive order rescinds two 1970s-era executive orders (11644 and 11989) that required federal agencies to use vague environmental and social criteria when designating off-road vehicle use on federal lands. It directs the Secretaries of War, Interior, Agriculture, the TVA Board, and other relevant agency heads to initiate rulemakings to remove or revise regulations based on those criteria, aiming to increase access for energy, timber, utility maintenance, and recreation.
