Forty-Seven States Have No Incentive to Destroy Farm Methane

A dairy farmer in Dane County, Wisconsin runs 900 cows on a well-managed operation. Her manure lagoon produces roughly 5,400 metric tons of CO2-equivalent methane every year. She knows it. Her county extension agent knows it. The EPA knows it. Nobody is paying her to stop it.

Two thousand miles west, a comparable operation in California's Central Valley produces the same methane from the same herd size. But that farmer has access to California's Low Carbon Fuel Standard, a credit market that can make methane projects worth millions annually. The Wisconsin farmer has access to nothing.

This is not a technology gap. It is a policy gap. And it covers 47 of 50 states.

Three States, One Market

The Low Carbon Fuel Standard exists in three states: California, Oregon, and Washington. These programs create tradeable credits for projects that reduce transportation fuel carbon intensity, including dairy biogas projects that inject renewable natural gas into pipelines.

In practice, LCFS credits have been the financial engine behind nearly every large-scale dairy methane project in the country. Without them, the economics of RNG production collapse for all but the largest operations. Federal programs like the Renewable Fuel Standard (D3 RINs) and the 45Z clean fuel tax credit help, but they were designed to stack on top of state credits, not replace them.

For a dairy in Vermont, Iowa, or North Carolina, the math is straightforward: no state credit program means no viable RNG project. The federal incentives alone do not cover the capital costs of gas upgrading, pipeline interconnection, and 15 years of operational risk.

Destruction Gets Even Less

If the RNG pathway is difficult outside LCFS states, the destruction pathway is nonexistent everywhere.

An enclosed flare can eliminate 98% or more of a lagoon's methane emissions within weeks of installation. The capital cost runs $150,000 to $400,000 depending on site size. There is no gas upgrading, no pipeline, no interconnection queue. It is the fastest, most reliable way to cut farm methane.

But flaring is not fuel production. It generates no RINs. No LCFS credits. No 45Z tax credits. The federal framework rewards converting methane into a commodity. It does not reward destroying it. A farmer who installs an enclosed flare and eliminates thousands of tons of annual emissions receives exactly zero dollars in federal incentive payments for doing so.

The Numbers That Explain the Inaction

According to the EPA's AgSTAR database, there are approximately 8,574 candidate dairy and swine operations in the U.S. with sufficient methane output to support some form of biogas project. Of those, roughly 400 have operational projects, almost all of them RNG facilities in LCFS states or very large operations that can make federal credits alone pencil out.

That leaves over 8,000 operations with no active methane project. The vast majority are in non-LCFS states. They are not ignoring the problem. They are responding rationally to a policy environment that offers them nothing.

The collective methane output of these unaddressed sites is staggering. EPA estimates that U.S. livestock manure management produces approximately 68 million metric tons of CO2-equivalent annually. The 400-odd active projects capture a fraction of that total. The rest vents directly into the atmosphere from open lagoons across the country.

State-Level Proposals Are Stalling

Several states have explored their own clean fuel standards or methane reduction incentive programs. Minnesota studied an LCFS in 2023 and shelved it. New York included methane reduction in its Climate Leadership and Community Protection Act but has not created a credit mechanism for farm projects. Michigan's agriculture department has grant programs, but they are small, competitive, and oversubscribed.

The pattern is consistent: states acknowledge the problem, study the options, and stop short of creating the financial mechanism that would actually move projects forward. The political dynamics are difficult. Clean fuel standards are complex. Agricultural methane sits at the intersection of climate policy, farm economics, and rural politics, a combination that makes legislators cautious.

Meanwhile, the Inflation Reduction Act directed billions toward agricultural conservation but allocated minimal funding specifically for methane destruction. The USDA's EQIP program can cover some flare costs, but program funding is limited and the application process is slow. A farmer who applies today may wait 12 to 18 months for a decision.

What a National Framework Could Look Like

The policy fix is not complicated in concept. A federal methane destruction credit, structured similarly to 45Q for carbon capture, would create a direct payment for verified methane elimination regardless of whether the gas is monetized or simply destroyed.

The Climate Solutions Act proposed by Senator Stabenow in 2024 included a version of this idea: a per-ton payment for verified methane destruction at agricultural sites, available to both RNG projects and flare-only installations. The bill did not advance past committee.

A destruction-neutral credit would change the economics overnight. A 500-cow dairy destroying 3,000 tons of CO2e per year at $30 per ton would generate $90,000 annually. That covers the annualized cost of an enclosed flare system with margin to spare. The farmer does not need to become a gas company. She just needs a check for the methane she stops from reaching the atmosphere.

Until that check exists, 47 states will continue to have thousands of farms producing methane that everyone agrees should be eliminated, with no economic reason to eliminate it.
