US EPA regions serve as a convenient base map for illustrating the range of mitigation credit values across the nation. The insert shows three regions leading the way in eco-asset value.
The U.S. mitigation banking industry is no longer a niche environmental business—it has become a large-scale ecological asset marketplace contributing a half-trillion dollars to the U.S. economy.
The Bottom Line
Numbers tell the story:
- More than $415 billion in mitigation credits have been released for sale nationwide, 1990s till now.
- More than $285 billion in mitigation credit transactions have occurred
- This leaves $130 billion in eco-assets currently held by U.S. mitigation bankers
- Almost 2.5 million acres have been dedicated to conservation in the process
What the Numbers Reveal
Apart from the scale of this marketplace, the depth of market absorption is equally striking. Roughly 70% of all mitigation credits released to market have been consumed by development -– infrastructure, energy, transportation, housing, and public works projects. This demonstrates an average of $8B per year in credit demand and verifiable transactions over the past thirty five years.
The industry appears to have grown much faster than public perception allows. In 2018 EASI tallied roughly $296 billion in authorized mitigation credit value, $12 billion in annual transactions, and 1.7 million acres in permanent conservation. Compared with the 2026 review, the marketplace has expanded materially.
Landowners may want to take note: ecological assets increasingly behave like recognized real-estate assets rather than regulatory obligations. The market has assigned measurable economic value to wetlands, streams, endangered species habitat, water quality functions, and related ecosystem services—a profound shift from how these resources were viewed a generation ago.
Background
Over the past few decades, the U.S. ecological asset marketplace has grown in scale and diversified significantly. Wetland and stream mitigation banking, species and habitat credits, water quality trading, groundwater markets, carbon markets, and related environmental finance mechanisms have grown in both geographic scope and economic significance nationwide.
At the same time, market intelligence has substantially improved. Over the ten years, EASI has gradually compiled the nation’s largest privately maintained database of ecological asset transactions—the Mitigation Credit Price Record (MCPR)—containing nearly four thousand market value references spanning wetland, stream, species, habitat, and related compensatory mitigation credit markets across the United States.
The 2026 review reflects increasing demand for compensatory mitigation—a net-positive outcome of policies addressing unavoidable impacts to land and water resources. Once viewed primarily as niche regulatory programs, environmental credit markets today influence land values, infrastructure development, watershed restoration, species recovery, and long-term land stewardship decisions across the country.
The 2026 Methodology
This year’s review began with the Regulatory In-lieu Fee and Bank Information Tracking System (RIBITS), an online public database maintained by the U.S. Army Corps of Engineers in cooperation with state and federal agency partners.
When development projects cause unavoidable impacts to wetlands, streams, species habitat, or other ecosystem services, federal law often requires compensatory mitigation. Developers commonly satisfy these requirements by purchasing environmental credits from mitigation banks or in-lieu fee (ILF) programs.
RIBITS serves as the nation’s primary public registry for this activity, tracking mitigation bank locations, service areas, credit availability, credit withdrawals, and associated project documentation.
EASI’s Mitigation Credit Price Report (MCPR) serves as a proprietary mitigation credit value repository.
Steps In the Analysis
As the basis for its analysis, EASI selected the 12 May 2026 RIBITS report titled “Available Credits by Credit Classification.” Data were reorganized by EPA Region and state as shown in Figure 1. For primary credit classes—including wetland, stream, and species credits where available—RIBITS reports Credits Available, Credits Released, and Credits “Withdrawn”, the latter interpreted for purposes of this analysis as credits used or sold.
Drawing upon its MCPR, EASI calculated average market values for the primary credit types within each state. Figure 2 illustrates this approach using Maryland wetland and stream credits. By multiplying credit inventories reported by RIBITS by average market values derived from MCPR, EASI estimated the value of released, transacted, and remaining mitigation credits.
These steps were repeated for every state for which RIBITS data were available.
Of interest, EASI has MCPR data for state and local mitigation credits that are not reflected in RIBITS, meaning the overall value of the U.S. mitigation credit marketplace is higher than what is represented for federal agencies alone. Further, the RIBITS report did not provide the number of credits that had been authorized as opposed to released. Released credits represent only those that have satisfied certain mitigation bank performance criteria, whereas authorized credits represent the total number of credits a bank can ultimately produce. It may take three to five years for all authorized credits to be released for sale or use, suggesting that substantial credit market value remains hidden from view.
For these reasons, EASI estimates that the total authorized value of the U.S. mitigation credit marketplace is approaching $500 billion—perhaps making it the largest environmental marketplace in the United States.

Credit inventories are reported by mitigation bank and credit type, including credits released, withdrawn (used/sold), and available, together with counts of mitigation projects and active banks.

Where the Value Lies
Mitigation credit markets vary dramatically by region.
Figure 3 shows that three regions of the country—the Northeast, Southeast, and Northwest—account for approximately 95% of all released mitigation credit value in the United States. Virginia leads the nation with 164 mitigation banks representing approximately $304 billion in released ecological asset value. Much of this value is associated with more than 1.3 million stream credits averaging about $550 per credit and 1.1 million wetland credits averaging approximately $263,000 per credit.
Figure 3. EPA Regions 3, 10 and 4 account for 95% of all released ecological asset value according to May, 2026 data.
Led overwhelmingly by Washington State, which accounted for 99% of its region’s total, EPA Region 10 ranked second nationally with approximately $67 billion in released mitigation credit value. EPA Region 4 ranked third with roughly $23 billion in released credit value. Florida alone represented approximately $13 billion, or 56% of the region’s total.
Together, Virginia, Washington, and Florida account for the vast majority of mitigation credit value within their respective regions, illustrating the highly concentrated nature of U.S. ecological asset markets.
Perhaps surprisingly, California—widely regarded as a leader in environmental market innovation and the birthplace of modern conservation banking—does not dominate the national mitigation credit marketplace. EPA Region 9, where California accounts for the majority of mitigation activity, generated approximately $8 billion in released credit value. This is likely due to the paucity of wetland habitat, most of which was converted to Central Valley agriculture or urban expansion, and to the state’s modest stream zone mitigation markets. Instead, the state manages a $1.6B conservation credit marketplace, the first and largest in the nation.
Nonetheless, the overall scale of California compensatory mitigation — $8B — is comparable to EPA Region 6, where Louisiana and Texas have generated approximately $5.2 billion and $2.6 billion in released credit value, respectively.
It also turns out that similar credit types can have radically different values. Nationally, wetland credits range from an average low of $8,600 per acre in Mississippi to an average high of $675,000 in New Jersey. A wetland credit in South Carolina averages $14,000, while neighboring North Carolina averages $134,000 – with both states having released about 1.1 million credits.
Why the differences? The analysis suggests that land value alone is not the primary driver. Mitigation credit prices are heavily influenced by supply and demand dynamics, including development pressure, permitting risk, credit scarcity, and competition among overlapping service areas. Some markets remain chronically undersupplied, while others have abundant credit inventories competing for a limited number of buyers.
Environmental conditions can also influence credit availability. Climate patterns, hydrologic conditions, and changes in species distribution or reproductive success may affect the pace at which mitigation credits are generated and released to the marketplace.
Conclusion
Ecological assets have matured into a national-scale asset class. What began as a compensatory mitigation requirement in the 1990s has evolved into a marketplace supporting hundreds of billions of dollars in ecological asset value, millions of conserved acres, and a demonstrated record of sustained demand across virtually every region of the United States.
As development continues to place pressure on wetlands, streams, species habitat, and other ecosystem services, compensatory mitigation is likely to remain an important tool for balancing economic growth with conservation and quality-of-life objectives.
