Part of Legacy Land, our guide for people who want to keep land whole. Start with Protect Your Land Forever; companions include the complete easement guide, grassland easements, and ranch easements.
A conservation easement is a simple bargain with an awkward problem. The bargain: a landowner gives up the right to plow or subdivide, permanently, and the land stays whole. The problem: someone has to pay for that promise, and most working ranches cannot afford to give it away. Public programs help. Donors help. More recently, a less obvious source joined them, and it came from the ground itself: the carbon held in prairie soil.
On the Zumwalt Prairie in eastern Oregon, a family ranch became, by The Climate Trust’s account, the first place where carbon offset finance helped pay for a conservation easement. The story is told in full in Two Ranches, One Idea. This page explains the mechanism, who it fits, and where it falls short.
How the money moves
The details change from ranch to ranch, but the shape is consistent.
- The easement. The landowner and a land trust agree on a perpetual easement that bars turning grassland into cropland and bars development. Grazing continues.
- The up front payment. A carbon funder pays toward the cost of that easement, which is the part a rancher usually cannot raise alone.
- The carbon. With the plow off the table, the soil carbon that plowing would have released stays in the ground. The funder turns that avoided loss into a project under a registry protocol, has a third party verify it, and sells the resulting credits.
- The ongoing revenue. The Climate Trust says the landowner then receives ongoing carbon revenue from the project. No rate is published, so the split lives in the contract, and that contract is the document to study.
Who is doing this
The Climate Trust is a Portland, Oregon nonprofit founded in 1997 as the first carbon offset fund in the country, created in response to Oregon’s carbon dioxide standard for power plants. By its own account, it helped develop registry methods for grassland carbon and formed some of the first rancher carbon cooperatives. Its grassland work is registered with registries such as the Climate Action Reserve.
We have no financial relationship with The Climate Trust. We write about it because the model is unusual and worth understanding, whoever ends up using it.
Why grassland
The World Wildlife Fund’s 2024 Plowprint report found that about 1.9 million acres of Great Plains grassland, across the United States and Canada, were converted to cropland in 2022 alone. That pace was slower than in some earlier years, but the losses keep adding up. Broken native prairie does not come back on any human timescale, which is why the easement is aimed at the moment conversion becomes tempting. Our grassland guide tells that story.
The carbon question, honestly
Avoided conversion is an accounting of something that did not happen. The credit stands for soil carbon that would have been released if the grass had been plowed, so someone has to judge how likely plowing really was. The registry methods take this seriously. Methods for avoided grassland conversion generally ask whether conversion would make financial sense and discount the credits for uncertainty about whether it would have happened. Your land has to pass that kind of test. Ground that could never be farmed is a poor fit. Ground that could be plowed next spring is a strong one.
The rules also move. Registries revise their protocols and retire older methodologies over time, so ask any funder which protocol, and which version of it, your project would use.
Who qualifies
The Climate Trust’s grassland program is built for larger ranches whose owners are ready to protect their grass from development and conversion to cropland, and its grassland page lists the current minimum acreage. Smaller ranches have joined through cooperatives, including ones on the Zumwalt Prairie in Oregon and in Montana. A checklist for your own land is in Is Your Land a Fit? Forest owners have a parallel path, described in Paying for Trees That Take Decades.
What it can stack with
The Climate Trust says its program can be used alongside the NRCS Agricultural Land Easement program or on its own, and several of its projects have combined the two. Some landowners also sell an easement for less than its appraised value, which is a gift of value with tax consequences. Our tax deduction guide and valuation guide cover the mechanics, and a tax advisor should cover your case.
The honest ledger
Every easement trades something for something. Here is what to weigh before you call anyone.
- It is permanent. An easement runs with the land forever, through heirs and buyers. Read the pros and cons and the estate planning guide first.
- The revenue is not guaranteed. The up front payment is real money. The ongoing share depends on credit sales and prices, and no rate is published. Ask to see the model.
- The threshold excludes many ranches. Acreage minimums and conversion tests mean some land will not qualify. Cooperatives help, but they need neighbors who are willing.
- One funder is not a market. Few organizations fund grassland easements with carbon, so you may have little competition to negotiate against. Compare any offer with public programs, land trusts, and donors.
- It is slow. Appraisals, land trust review, and credit verification each take their time. Plan in seasons, not weeks.
If you want to talk it through
Ideal Location is an independent nature advocacy platform, not a land trust. We do not hold easements, fund projects, or take any interest in your land, and no group pays us to send landowners its way. Tell us about your land and what you hope for it, and we will point you to the land trusts and conservation groups whose work fits, and help you get ready for those first conversations. Talking with us is free. We are not attorneys, appraisers, or tax advisors. Legacy Land explains how this works.
Ideal Location
Own grassland or working forest in the American West?
Every piece of land has its own set of options, and they depend on the place, the people who own it, and what they hope for it. The more you tell us, the better we can map yours and point you to the land trusts and conservation groups whose work fits.
Only your name, email, and state are required. Answer what you can and skip the rest.
Free, with no obligation. Ideal Location is an independent nature advocacy platform. The organizations in our directory do not pay us, and we never share your details with anyone without asking you first.
Frequently asked questions
Can a conservation easement be paid for with carbon credits?
In some cases, yes. The Climate Trust has used up front carbon finance to help pay for grassland easements held by land trusts, beginning with the Zumwalt Prairie in Oregon.
Can I still graze cattle?
The Climate Trust says grazing and daily ranch operations continue. The easement bars converting grassland to cropland and development, so read the actual easement terms for your land.
How many acres do I need?
The Climate Trust’s grassland program is aimed at larger ranches, and its grassland page lists the current minimum acreage. Smaller ranches have joined through cooperatives.
Does carbon funding replace public easement money?
No. The Climate Trust says its program can be used alongside the NRCS Agricultural Land Easement program or on its own.
