RGGI at 20: What the Northeast Cap-and-Trade Program Has Achieved and Where It Falls Short

Twenty years after the Regional Greenhouse Gas Initiative launched, Northeastern power sector emissions are down by half and states have collected more than $10 billion in auction revenue. But progress has flattened since 2020, carbon allowance prices have risen from $3.07 to $37.65 per ton, and critics say the program is not doing enough to drive the next wave of clean energy construction. The article covers the main fault lines: the coal-to-gas shift that powered early reductions is largely complete, offshore wind has stalled, and PJM generators in non-RGGI states can undercut regional plants that carry a carbon price. Supporters point to revenue-funded efficiency programs and billions of tons of avoided emissions. Opponents, including New Jersey business groups, want a cheaper state-level fee instead. For anyone tracking carbon markets or grid decarbonization, this is a useful look at how a mature cap-and-trade program behaves once the easy reductions are gone.

Good overview of where RGGI actually stands. The early emissions drop was mostly coal retirements, and the remaining reductions are much harder. The article makes the PJM leakage problem clear. Worth reading if you care about whether a carbon price can survive contact with real grid economics.

The revenue side is underrated. RGGI raised over $10 billion and the 2024 proceeds alone are projected to avoid 4.3 billion tons over their lifetime. But the auction price at $37.65 still is not high enough to push transmission and offshore wind forward. The article gets that tension right.

The leakage argument deserves more attention. If generators in PJM states outside RGGI do not pay a carbon price, then more expensive regional plants lose market share and dirtier imports win. That is not a cap and trade failure exactly, but it is a design gap that no allowance price solves on its own.

Agreed. RGGI was built for a grid where coal was the marginal fuel. Now the binding constraints are interconnection queues, siting, and state policy. A clean electricity standard paired with a carbon price would do more than another round of allowance tightening. The article hints at that but could go further.

One thing the piece does not stress enough: RGGI revenue funds efficiency programs that lower bills. In New England the 2025 investments are projected to save $1.3 billion over their lifetime. That is the part worth defending when the price spike makes headlines.
