How much could Irish farmers earn from carbon credits per hectare?
The single question every tillage grower asks. Here is the answer with the caveats attached, using only published sequestration rates and current market prices.
The economics, per hectare
The value of a credit per hectare is the sequestration rate multiplied by the carbon price. Both need to be stated honestly. Teagasc work indicates minimum tillage on its own sequesters roughly 0.3–0.7 tonnes of CO₂ per hectare per year; reaching the upper end, or beyond, requires the full package of cover crops, residue retention and reduced nitrogen. The 2.86 t/ha/yr figure quoted in some international meta-analyses derives from other climates and cropping systems and is not replicable in Irish conditions; it appears below only as a ceiling, not an expectation. Agricultural credits currently trade at roughly €45–68/t, with European regenerative-agriculture projects around €49–60/t and some EU agricultural land-management projects higher again; €50/t is used here as a mid-range working figure, not a fixed price.
| Carbon sequestered (t CO₂/ha/yr) | @ €40/t | @ €50/t | @ €60/t | @ €70/t | @ €80/t |
|---|---|---|---|---|---|
| 0.3 — min-till, low end | €12 | €15 | €18 | €21 | €24 |
| 0.5 — realistic core | €20 | €25 | €30 | €35 | €40 |
| 0.7 — min-till, upper | €28 | €35 | €42 | €49 | €56 |
| 1.0 — full package | €40 | €50 | €60 | €70 | €80 |
| 1.5 — strong, fully stacked | €60 | €75 | €90 | €105 | €120 |
| 2.86 — international ceiling (not for Irish planning) | €114 | €143 | €172 | €200 | €229 |
A realistic planning figure is €25–40 per hectare per year for a genuine minimum-till and cover-crop system at a €50 price, with €60–120 achievable only where practice is strong, soils respond and the price holds. Over a five-year contract the realistic band is €150–300 per hectare, before savings.
On top of the credit, reducing cultivation is generally reported to save on the order of €20–60 per hectare a year in diesel, labour and machinery wear — cash regardless of whether the credit sells. For a 60-hectare grower that is roughly €1,800–3,600 a year from the credit and a similar amount again in savings; for 120 hectares, about double. Measurement, certification and administration take a share, so a realistic expectation is that the farmer retains 60–80% of the credit value, with smaller holdings aggregated through co-ops to keep the per-hectare cost of verification manageable.
Worked examples
For a 60-hectare grower the credit is in the region of €1,800–3,600 a year with a similar amount again in cultivation savings; for 120 hectares, roughly double. Over a five-year contract the realistic credit band is €150–300 per hectare. None of this transforms a farm's accounts on its own — it is a layer on top of margin, and it should be presented that way.
Integrity — the conditions that make it real
A credit that buyers do not believe is worth nothing, so the safeguards are the product, not the paperwork:
- Measurement, reporting and verification — Teagasc soil-sampling combined with remote-sensing checks on residue cover and cultivation depth, calibrated to the EU CRCF methodology, each credit carrying a stated uncertainty range rather than a single flattering figure.
- Additionality — payment only for practice beyond current common practice and any regulatory baseline, not for what would have happened anyway.
- Permanence and reversal — a minimum five-year commitment, a buffer pool of credits held back against reversals, and a contractual clawback if a participant ploughs the sequestered carbon back out.
- Leakage — monitoring at farm and regional level so carbon “saved” here is not simply displaced into more intensive cultivation elsewhere.
How this connects to what IMPT already does
IMPT is a hotel-booking platform that funds one tonne of verified carbon offset on every booking, with access to more than eight million hotels and apartments across 195 countries. It runs a one-partner-per-territory model in which each partner earns a share of IMPT's booking margin and every booking carries that tonne of offset. In other words, IMPT already puts corporate and consumer money behind verified carbon — the same demand-side that an Irish Tillage Credit would need. An officially-backed domestic removal credit for tillage is a natural extension of that thinking: local, traceable and measured, rather than a distant offset of uncertain quality.
Questions & answers
What carbon price is used in these estimates?
€50 per tonne as a mid-range working figure. Agricultural credits currently trade at roughly €45–68/t and European regenerative-agriculture projects at €49–60/t; the voluntary market is volatile, so no single price is fixed.
How much does the farmer keep?
A realistic expectation is that the grower retains 60–80% of the credit value after measurement, certification and administration, with co-op aggregation used to keep verification costs manageable on smaller holdings.
What are the cultivation savings worth?
Reducing tillage is generally reported to save on the order of €20–60 per hectare a year in diesel, labour and machinery wear — cash regardless of whether the credit sells, though it varies with system and contractor arrangements.
