Carbon Credits for Stubble and Crop Residue: What Farmers Actually Get Paid For

What is a carbon credit, in simple words?

Certain gases collect in the sky and make the earth hotter. Everyone adds some. Factories and power plants add a lot.

Many companies are now under pressure — sometimes under law — to reduce what they add. They cannot always do it inside their own factory. So they pay somebody else to reduce it instead.

That is all a carbon credit is: proof that one tonne of these gases was kept out of the sky, which a company can buy.

Farming makes these gases too — from flooded rice fields, from fertiliser, from burning stubble. So if you farm in a way that releases less, that saving can be measured, checked by an outside inspector, and sold.

The one rule that decides everything

Before you read anything else, understand this one rule. It explains almost every disappointment in this business.

Hold on to that rule. Now let us look at your stubble.

Do I get carbon credits for not burning my stubble?

Many farmers are told something like: "You have stopped burning your parali, so you must be earning carbon credits."

It sounds right. It is almost always wrong. Here is why.

Reason one: the amount is tiny

When straw burns, most of what comes out is the same carbon the plant took from the air a few months ago while it was growing. That part does not count — it went up, it came down, no net change.

Only a small part of the smoke counts. Burning one tonne of straw creates only about 0.08 tonnes of the gases that are counted. That is roughly one-twelfth of a single credit.

So a large operation collecting 5,000 tonnes of straw a season — a serious business, hundreds of trolleys — saves only about 410 tonnes in a whole year.

Now consider what it costs to claim it. Every carbon project must be inspected and audited by an approved outside agency, every single year. Those fees alone run into tens of lakhs. You would spend far more proving it than you could ever earn from it.

Reason two — the bigger one: it is not "extra"

Remember the rule. Two things get in the way:

• Burning crop residue is already against the law in much of India. You do not get paid for obeying the law.
• Most farmers already do not burn it. If a practice is already normal in your area, it is not a change. The registries have an actual cut-off for this: if more than about 20% of the area already does it, it usually does not qualify.

So: not burning your stubble is a genuinely good thing. It is better for your village's air and for your children's lungs. It is just not a thing anyone will pay you carbon money for. Be careful of anyone who tells you otherwise.

Does selling straw as cattle fodder earn carbon credits?

No. There is no carbon credit in it at all.

The cow eats the straw and digests it. The carbon goes back into the air within a few months. Nothing was stored, nothing was saved.

In fact plain untreated straw is poor-quality feed, and poor feed makes cattle produce more gas per litre of milk, not less. Treating straw to improve it — urea treatment, for example — is genuinely useful for your animals and your milk yield. But do not expect carbon money for it today.

Sell your straw. Get a good price for it. Just do not let anyone tell you the sale comes with carbon credits attached.

Where is the real carbon money on my farm?

Now the part worth your attention.

The carbon money on your farm is not in the straw lying on top of the field. It is in the water standing on it during the rice season.

Why standing water is the problem

When your paddy field stays flooded for weeks, no air can reach the mud underneath. In that airless mud, a particular kind of bacteria grows — and it produces methane, a gas that traps far more heat than ordinary carbon dioxide.

This is why rice, out of all our crops, has the biggest carbon opportunity. Not because rice is bad. Because there is a genuine, well-tested way to reduce it.

The fix is simple and old

Instead of keeping the field flooded all season, you let it dry a little between waterings, then water it again. The field is never dry enough to stress the crop — just dry enough to let some air into the mud, which stops the bacteria.

The method is called Alternate Wetting and Drying, or AWD. Here is how it actually works in a field:

1. Put a pipe in the ground. A simple plastic pipe with holes in it, sunk into the soil — a pani pipe. You look inside and see how far the water has gone down. Nothing electronic.
2. Wait until the water drops about 15 cm below the surface. Roughly a hand's depth. Then water again.
3. Stop the drying when the crop is flowering. During flowering, keep the water standing as usual. This is the sensitive stage — do not experiment here.
4. Repeat through the season. That is the whole method.

Done properly, this cuts methane by roughly half. Our detailed guide on how AWD carbon credits work for Indian rice farmers goes deeper into the practice and the evidence behind it.

How much can I earn per acre from AWD rice?

To put that in the units this business uses: about 4 to 6 credits per hectare per season, which is roughly 1.5 to 2.5 credits per acre.

On 5 acres of paddy, that is very roughly ₹5,000 to ₹15,000 a season before deductions. It will not replace your crop income. It is not nothing either — and it comes from water you were going to use anyway. For a fuller picture across all the practices, see how much farmers can realistically earn from carbon credits.

What do I gain if the carbon money never arrives?

This matters, so read it twice.

Watering this way uses noticeably less water. Less water means fewer pump hours. Fewer pump hours means less diesel, or less electricity, or less strain on your borewell.

That saving is yours from the very first season. It does not depend on any company, any inspector, any paperwork or any payment ever arriving.

So judge the practice on its own merit first. If the carbon payment comes on top, treat it as a bonus. Never the other way round.

What should I check before signing with a carbon company?

This is the most important section in this article.

A study published in 2024 surveyed 841 farmers across 7 carbon projects in 28 villages in Haryana and Madhya Pradesh. It found that more than 99% of them had received no money at all.

The most common reason was not fraud in the dramatic sense. It was simpler: many of those projects were never properly registered. No registration means no credits were ever created. No credits means there was never anything to sell, and never anything to pay you from.

Two more warnings worth knowing:

• Never sign with two projects for the same land. The same saving cannot be sold twice. If two projects claim your field, both usually stop paying.
• Nothing worth having asks for money up front. A genuine project pays you. It does not charge you a "registration fee".

If you belong to an FPO or a cooperative, you are in a much stronger position — a group can ask harder questions and negotiate a better share than one farmer alone. Our guide on carbon credits for FPOs covers how a group should set this up.

Should I sell all my crop residue?

This has nothing to do with carbon credits, and everything to do with your land.

Straw that stays on the field rots down and becomes food for the soil. It feeds the earthworms, holds moisture, and slowly builds up the dark organic matter that makes soil healthy.

If you sell every bit of residue off every field, every season, year after year, your soil quietly gets weaker. You will notice it as more fertiliser needed for the same yield, and soil that dries and hardens faster.

If you are the one buying the straw

This section is for straw buyers, balers, fodder businesses and project developers rather than farmers. It carries the technical detail behind everything above.

If you run a residue collection and baling operation buying from several hundred farmers, the honest summary is this: your carbon asset is not the straw. It is the farmer network you built to get it.

Aggregation is the hardest problem in Indian agri-carbon. A two-acre farmer can never carry the cost of measurement, verification and audit alone. Projects live or die on whether somebody can enrol, contract and monitor hundreds of growers at once. If you already buy from 500–1,000 farmers, you have built — as a by-product — the exact thing most developers spend years and crores trying to assemble. And those farmers grow paddy.

Three things to get right, in order:

• Instrument the business before you design a carbon project. From season one, capture farmer identity and consent, plot boundaries and area, tenure evidence, crop calendar and tonnes delivered per plot — digitally. That dataset is the asset.
• Put carbon rights in the procurement agreement from day one. Registries require documented proof that you hold the right to the credits. Retrofitting informed consent across a thousand farmers in year three is slow, expensive and often fatal to the timeline. A clause in a contract they are already signing costs nothing.
• Mind the soil carbon conflict. Verra's VM0042 treats soil organic carbon as a mandatory pool that cannot be excluded as de minimis, and residue removal depletes it. You cannot sell soil carbon from fields you are stripping. Either leave a contracted fraction in-field, return carbon as biochar or digestate, separate the geographies, or skip soil carbon and concentrate on rice methane.

On scale: standalone registration must absorb validation, annual verification, registry fees, baseline sampling and a buffer withholding of typically 10–20% of credits. Most projects need volumes well into the tens of thousands of tonnes a year before that overhead makes sense. Below that, join an established grouped project as a participating instance, prove the model, then graduate. Expect 18 to 30 months from serious design to first credit revenue, and plan cash flow accordingly — practice change costs money long before credits pay.

Finally, keep an eye on India's Carbon Credit Trading Scheme (CCTS). Its offset mechanism includes agriculture in the Phase 1 sectors, with BEE's detailed procedure out since 2025 and methodologies being notified progressively. A domestic compliance-linked demand pool would change the economics meaningfully — a reason to build the data foundation now, not a reason to wait.
