Sources & Assumptions
| Parameter | Value Used | Notes / Source |
|---|---|---|
| EF – Cow | 72 kg CH₄ / head·yr | Conservative mid-range from IPCC / ICAR / FAO |
| EF – Buffalo | 90 kg CH₄ / head·yr | Buffalo emits more (India research) |
| Diet reduction | 0% / 8% / 12% | Conservative values (real-world achievable) |
| Harit Dhara (ICAR) | 18% reduction | ICAR studies show ~17–20% |
| Seaweed | 25% reduction | Average from multiple trials |
| 3-NOP | 30% reduction | Proven in global studies |
| Oils | 8% reduction | Typical range 8–15% |
| CH₄ → CO₂e (GWP) | 27.2 (IPCC AR6 – latest update) | Most up-to-date science |
| Cars | 4.6 t CO₂e / car·yr | US EPA |
| Trees | 0.021 t CO₂e / tree·yr | FAO / UNEP global average |
Note: If weight is provided, the emission factor is computed from animal weight and diet using a Tier-2 style approach (DMI% by diet, GE = 18.45 MJ/kg DM, Ym by diet, CH₄ energy = 55.65 MJ/kg). If weight is not provided, the tool uses conservative default emission factors.
