Report: U.S. greenhouse gas emissions growing faster than economy

Preliminary Rhodium Group estimates show U.S. greenhouse gas emissions rose 2.4% in 2025, outpacing inflation‑adjusted GDP growth of 1.9%, driven primarily by a 3.8% rise in energy-sector emissions and a 6.8% increase from building heating. A colder winter and a 58% spike in natural gas prices boosted coal-fired generation and slowed coal retirements amid changes in federal energy policy, while solar generation grew 34%. Transportation remains the largest source of emissions, edging up 0.1% as diesel and jet fuel use rose despite more fuel-efficient vehicles. Total emissions remain below 2019 levels (6% lower).

Analysis

Market structure: Near-term winners are thermal-coal producers and coal-heavy utilities (e.g., BTU, ARCH, KOL ETF) plus refiners (VLO, MPC) because a 58% rise in natural gas in 2025 and a colder winter drove fuel switching to coal and stronger diesel/jet demand. Solar remains the fastest-growing source (+34%) but faces policy headwinds that slow merchant-utility offtake; that bifurcation increases pricing power for fossil generators while leaving equipment OEMs exposed to demand timing risk.

Risk assessment: Tail risks include a regulatory reversal (e.g., federal carbon policy or clean-energy subsidies reinstated after an election) that could strand coal assets within 12–36 months, or a sharp natural gas supply response (LNG ramp or warm winter) that cuts gas price >20% in 1–3 months and collapses coal burn. Hidden dependencies: U.S. coal demand is sensitive to regional gas spreads and plant outage schedules; LNG export volumes and storage data are immediate catalysts. Monitor weekly EIA storage and front-month Henry Hub volatility as 0–90 day triggers.

Trade implications: Tactical—favor short-duration, event-driven energy plays: establish 2–3% long positions in BTU/ARCH or KOL for 3–6 months to capture coal burn upside, and 1–2% long in VLO/MPC for refining crack expansion tied to diesel/jet demand over 1–3 months. Use pair trades (long MPC vs short TAN) to express fossil-refiner vs solar installation divergence; implement call spreads (buy 3-6 month VLO 1x2 call spreads) and protect positions with puts if Henry Hub drops 20%.

Contrarian angle: The market underestimates persistence of solar OEM strength despite policy drift—FSLR/ENPH exposures should be sized as 6–24 month recovery/structural plays rather than immediate shorts. Conversely, coal rallies may be overbought: if weekly Henry Hub futures decline >25% or a credible carbon price re-emerges, unwind coal longs quickly; history (2018 gas spikes) shows coal rebounds are often <12 months before structural declines resume.

Key Decisions for Investors

• Establish a 2–3% portfolio long in Peabody Energy (BTU) or Arch Resources (ARCH) or KOL ETF with a 3–6 month horizon to capture higher coal burn; set a hard exit if front-month Henry Hub falls >20% from current levels or if federal policy signals a coordinated carbon-pricing plan.
• Allocate 1.5–2% long to refiners Marathon Petroleum (MPC) or Valero (VLO) via outright or 3–6 month call spreads to play diesel/jet demand; take profits on a 15–25% rally in refining margin or if U.S. product demand declines for two consecutive weekly EIA reports.
• Initiate a pair trade: long MPC (1.5%) vs short TAN ETF (1%) for 1–3 months to capture divergence between fossil-fuel demand and near-term solar installation slowdowns; rebalance after quarterly installation/utility procurement updates.
• Establish a 1–2% strategic long in First Solar (FSLR) or Enphase (ENPH) with 6–24 month horizon to catch structural solar growth (34% Y/Y) while hedging with a 6–12 month put if policy support is reinstated or module ASPs fall >15%.
• Reduce duration exposure to long-term government bonds by 0.5–1% of portfolio weight in favor of commodity-linked exposure (natural gas futures or energy sector ETF XLE) given upside inflationary risk from higher energy prices over next 3–12 months; trim if CPI-linked breakevens drop 30 bps.
