Carbon Credits in Agriculture
Carbon Credits in agriculture are certificates generated when farming practices reduces green house or remove carbon di oxide from atmosphere and it stores in soil or vegetation.
A. How it works :
- A farmer should grow the trees or plants that helps in increasing carbon storage and reduce emissions.
- The carbon produce will be measured or measured by approved methods.
- An independent verifier confirms their result.
- Carbon credits are issued, typically with 1 carbon credit = 1 metric ton of CO₂-equivalent (CO₂e) reduced or removed.
- The carbon credits are sold to companies seeking to offset emissions.
B. Agricultural practices that can generate carbon credits:
- No-till farming – This tilling reduces the disturbance of the soil and helps in increasing soil carbon.
- Cover cropping – The plants grown in between cash crops helps in building soil organic matter.
- Agroforestry –Growing tress in between cash crops or livestock stores carbon biomass and soils.
- Grazing management – By grazing rotationally soil carbon can be improved.
- Rice cultivation – Alternate wetting and drying methods can reduce methane emissions.
- Efficient fertilizer management – By using organic fertilisation we can reduce nitrous oxide in soil and also helps in increasing carbon.
- Methane capture from livestock manure – captures biogas that would otherwise be released.
C. Benefits for farmers:
- Additional income from credit sales.
- Improved soil health and water retention.
- Potential increases in long-term productivity.
- Enhanced resilience to drought and climate variability.
D. Challenges:
- Measuring soil carbon accurately can be complex and costly.
- Carbon storage may need to be maintained for many years.
- Credit prices can fluctuate.
- Verification and certification requirements can be demanding.
- Some projects have high upfront costs.
E. Carbon credit programs and standards:
Common standards include:
- Verra
- Gold Standard
- American Carbon Registry
- Climate Action Reserve
The Indian government is also developing broader carbon market mechanisms through the Bureau of Energy Efficiency and related initiatives.
For a farmer in Karnataka, carbon credit projects are often most viable when many farmers
participate together through a cooperative, farmer producer organization (FPO), NGO, or project
developer, because monitoring and verification costs can be shared.
The amount a farmer can earn from carbon credits depends on:
- The farming practice adopted
- Soil type and climate
- Crop grown
- Project size
- Carbon credit price
- Measurement and verification costs
F. Typical Carbon Sequestration Rates:
For practices such as no-till farming, cover cropping, and regenerative agriculture, farms often generate roughly 0.2–1.5 tonnes CO₂e per acre per year (about 0.5–3.7 tonnes CO₂e per hectare per year). Actual results vary significantly by region and methodology.
Example earnings
If carbon credits sell for US$10–30 per tonne CO₂e:
| Area | Carbon Credits Generated | Approximate Annual Revenue |
|---|---|---|
| 1 acre | 0.2–1.5 credits | US$2–45 |
| 1 hectare | 0.5–3.7 credits | US$5–111 |
At an exchange rate of roughly ₹83–85 per US dollar, this is approximately:
| Area | Approximate Annual Revenue |
|---|---|
| 1 acre | ₹170–₹3,800 |
| 1 hectare | ₹425–₹9,500 |
G. Reality for small farmers in India:
For individual smallholders, carbon-credit income is often modest. Many projects report net
earnings in the range of ₹500–₹5,000 per acre per year, depending on the practice, carbon price,
and project structure. In some cases, payments are lower after accounting for project developer and
verification fees.
Because of these costs, farmers are usually grouped through:
- Farmer Producer Organizations (FPOs)
- Cooperatives
- Contract farming groups
- Carbon project developers
Example: Karnataka farmer
Suppose a farmer has:
- 5 acres
- Adopts regenerative practices
- Generates 1 credit per acre annually
- Receives ₹1,200 per credit after fees
Annual carbon income could be approximately:
5 acres × ₹1,200 = ₹6,000 per year
If the project achieves higher sequestration rates or credit prices rise, income could be substantially higher.
H. Important point:
For most of the farmers Carbon Credit is not main income, it is a alternative income, he doesn’t depend solely on carbon credit. The larger economic benefit often comes from:
- Reduced fertilizer and fuel costs
- Better soil health
- Improved water retention
- More stable yields over time
