RGGI Under Fire: Is a Key Climate Program Increasing Emissions and Costs?

SALT LAKE CITY, UT – April 30, 2026 – A landmark U.S. climate initiative is facing explosive allegations that it is not only failing to achieve its primary goal but is actively making the problem worse. A new independent analysis released today by research firm Alpha Inception claims the Regional Greenhouse Gas Initiative (RGGI) has inadvertently caused a net increase in carbon dioxide emissions across the multi-state PJM electrical grid, all while imposing a multi-billion-dollar burden on consumers.

The report estimates that from April 2025 to March 2026, the program led to an additional 2.86 million tons of atmospheric CO₂, the equivalent of adding 565,000 gasoline-powered cars to the road for a year. These findings challenge the foundational premise of the cap-and-trade program, which has been hailed as a model for market-based environmental policy.

The Carbon Leakage Conundrum

At the heart of the critique is a phenomenon known as “carbon leakage.” RGGI requires power producers in its member states—a coalition of northeastern and mid-Atlantic states—to buy allowances for every ton of carbon they emit. This cost, the “carbon adder,” is intended to make cleaner energy sources more competitive.

However, Alpha Inception’s dispatch model argues this has created a perverse incentive within the vast PJM Interconnection, the regional grid operator managing electricity flow for 65 million people from Illinois to the East Coast. The analysis suggests that the carbon cost has made some efficient natural gas plants within RGGI states too expensive to run. As a result, PJM’s automated system dispatches cheaper electricity from power plants in non-RGGI states like Pennsylvania, Ohio, and West Virginia to meet demand. The problem, according to the report, is that these replacement plants are often older and less efficient, emitting 30-45% more CO₂ per megawatt-hour generated. The net effect is a shell game where emissions are not eliminated but simply shifted to less-regulated areas, leading to an overall increase in pollution.

This isn't the first time such concerns have been raised. An independent white paper by Tabors Caramanis Rudkevich (TCR) reached similar conclusions, finding that RGGI's presence in the PJM market had shifted from reducing CO₂ to increasing it, alongside significant consumer cost hikes. Even PJM's own simulations have acknowledged the dynamic; a 2025 analysis projected that if Pennsylvania were to join, its in-state emissions would fall, but overall PJM emissions would remain “relatively flat” as generation shifted to out-of-state fossil fuel plants.

The Multi-Billion Dollar Price Tag

Beyond the environmental impact, the financial implications are staggering. The analysis claims that at current allowance prices, which have recently soared above $40 per ton, RGGI imposes between $9 billion and $10 billion annually in additional wholesale electricity costs across the PJM region. In contrast, the program generates only about $3 billion in auction proceeds for member states.

This creates a significant cost disparity, particularly for states that are part of the PJM grid but not RGGI. The report estimates that consumers and businesses in non-member states like Pennsylvania, Ohio, and Illinois are shouldering approximately $2 billion of these higher electricity costs without receiving any of the auction revenues, which RGGI states typically reinvest in energy efficiency programs and consumer rebates.

Alpha Inception attributes the recent 60% price rally in RGGI allowances not to market fundamentals but to a “structural term-mismatch.” The firm suggests that large power consumers, such as data centers, are attempting to hedge their multi-year electricity needs in a market designed for short-term, quarterly compliance, creating artificial scarcity and driving up prices.

A Tale of Two Virginias: The Policy Flashpoint

The debate is coming to a head in Virginia, which has a fraught and politically charged history with the carbon market. After joining RGGI in 2021, the state was pulled out by the administration of Governor Glenn Youngkin at the end of 2023, citing rising energy costs. Now, under the new administration of Governor Abigail Spanberger, the state is on a fast track to rejoin, with a target date of July 1, 2026.

Alpha Inception’s report directly challenges this move, recommending that RGGI states “pause Virginia’s July 1, 2026 entry until January 2027.” The firm argues that adding Virginia back into the system under current market conditions will materially worsen both the emissions leakage and the consumer cost burden. This puts Virginia’s Department of Environmental Quality (DEQ), which is currently finalizing rules for re-entry, at the center of a high-stakes policy battle.

A Program Divided: Supporters Tout Long-Term Success

Despite the pointed criticisms, supporters of RGGI maintain that it is a proven success. Proponents, including the Environmental Defense Fund (EDF), point to the program's long-term record, arguing that RGGI has helped cut power plant pollution by half in participating states since its inception—a rate twice as fast as the national average. They contend that the billions of dollars in auction revenue have funded critical investments in clean energy, created jobs, and delivered substantial health benefits by reducing other harmful air pollutants.

Officials in member states like Maryland highlight that since the program began, RGGI states have seen a 16% deeper reduction in greenhouse gas emissions compared to non-RGGI states. From their perspective, the program is a cornerstone of their climate strategy and a vital tool for achieving ambitious emissions targets. They argue that focusing on short-term market fluctuations or leakage overlooks the program's transformative long-term impact on the region's energy mix.

To address market volatility, RGGI has built-in mechanisms like a Cost Containment Reserve (CCR), which can release additional allowances if prices get too high. However, critics argue these tools are insufficient to handle the market distortions seen today. Alpha Inception has proposed more aggressive reforms, including an illustrative price cap of around $20 per ton and restoring forward-vintage auctions to allow for better long-term hedging. This growing chorus of critiques has intensified the debate over whether RGGI needs a fundamental redesign to ensure it can effectively reduce emissions without imposing unintended economic and environmental consequences.
