Carbon & Credits
Methodology, carbon bank measurements, feed distribution, and credit pipeline.
Methodology
Three carbon abatement sources, calculated with the formulas and parameters of HiFeed's carbon accounting workbook.
Source 1
Enteric fermentation emission reduction
ER = Σ (feed kg ÷ daily DMI) × ER/cattle-day
- Baseline EF 1.01 tCO₂e/cattle/yr (FAO GLEAM, SE Asia)
- Project EF 0.597 tCO₂e/cattle/yr (current formula)
- ER/cattle-day = 0.001132 tCO₂e
- Reference animal 300 kg; DMI 9 kg / 3 kg / 7.5 kg (Indigofera / GC / pellets)
Source 2
Raw material offtake carbon sequestration
Seq = offtake kg × (20 tCO₂e/ha/yr ÷ net dry yield kg/yr)
- 15 t fresh × 4 harvests × 33% DM × (1 − 14% spoilage)
- Net dry yield = 17,028 kg/yr
- Factor = 0.001175 tCO₂e/kg
- Indigofera offtake 25,150 kg → 29.54 tCO₂e
Source 3
Carbon sequestration from carbon banks
Stock = (AGB + BGB) × 0.47 × 3.67 + SOC × 3.67
- AGB: Chave et al. (2005) allometry, field measurement
- BGB = AGB × R (0.258 Indigofera, 0.956 Hybrid Napier)
- SOC: lab analysis at 0–10, 10–20, 20–30 cm
- Sequestration = stock increase between consecutive measurements
Carbon Bank Stations
Measured carbon stock per station (tCO₂e). Total sequestration: 213.31 tCO₂e.
| Station | Area (ha) | Measurements | Sequestration |
|---|---|---|---|
C1 · Canggu 1 Indigofera plantation (3.65 ha) + unvegetated strata (1.95 ha) | 5.6 |
| 179.01 |
C2 · Canggu 2 Hybrid Napier (Pakchong) plantation | 0.51 |
| 32.63 |
TS1 Carbon bank station | 0.4 |
| 1.67 |
GT1 Carbon bank station (single measurement, no sequestration claimed yet) | 0.72 |

Feed Distribution & Enteric Reduction
Kg distributed per month, converted to cattle-days and tCO₂e. Total: 20.89 tCO₂e.
| Month | Indigofera (silage / hay / mesh) (kg) | Green Concentrate (kg) | Complete Feed Pellets (kg) | Cattle-days | tCO₂e |

HiFeed Carbon Cycle
Two primary pathways through which HiFeed generates verified carbon credits.
Feedstock Carbon Sequestration
CO₂ absorbed during raw material cultivation
Crop Cultivation
Feed raw materials are sustainably farmed by local agricultural partners
Photosynthesis
Plants absorb atmospheric CO₂ and store carbon in biomass during growth
Harvest & Processing
Raw materials are harvested and processed into HiFeed complete feed pellets
Carbon Stored
Carbon from raw material offtake and carbon bank stations is quantified in tCO₂e
242.8 Ton CO₂eEnteric Methane Reduction
CH₄ avoided from rumen fermentation
Feed Consumption
Cattle consume HiFeed pellets containing anti-methanogenic compounds
Rumen Fermentation
Active compounds inhibit methanogen microbes in the rumen, reducing CH₄ production
Emission Reduction
Enteric methane emissions from cattle are significantly reduced
Avoided Emissions
Avoided CH₄ is quantified in tCO₂e against the FAO GLEAM baseline emission factor
20.9 Ton CO₂eCarbon Credit Pipeline
End-to-end tracking from measurement to market.
263.7 t
Measured
tCO₂e abated across enteric, raw material offtake and carbon banks
