Agriculture — what makes this sector technically different.
The only sector where the largest emission sources are biological processes with wide natural variability, and where a default factor can be off by more than the reduction being claimed.
Hardest data points
Where inventories in this sector fail.
- Direct and indirect N₂O from managed soils, which usually dominates and is derived from application rates and factors rather than measured
- Enteric fermentation and manure management, where the management system chosen changes the CH₄ figure more than herd size does
- The biogenic carbon boundary — which flows are reported separately from fossil emissions, and whether biogenic CO₂ is being netted against fossil CO₂
- Land use and land use change, and whether a conversion inside the accounting window has been identified at all
- Soil organic carbon claims, which require a measurement or model basis and a stated permanence period, not an assertion
- Fertiliser and lime application records reconciled to purchase records and to treated area
- Fuel used by contracted machinery, which sits outside the direct operations but inside the boundary
- Tier level actually applied against the tier the criteria require, and the emission factors' geographic representativeness
What is examined
The evidence we will ask for.
- Application records for nitrogen fertiliser, manure and lime, by field or management unit
- Livestock numbers by category and the manure management system for each
- The emission factor set used, its tier, and its geographic and climatic basis
- Land use records covering the full accounting window, including any conversion
- Where soil carbon is claimed: the sampling or modelling basis and the permanence period stated
- Fuel and energy records including contracted operations

The normative frame
The standards the work runs under.
ISO 14064-1:2018 · ISO 14064-3:2019 · ISO 14067:2018 for product claims. Biological source methodologies follow the IPCC Guidelines for National Greenhouse Gas Inventories and the applicable programme requirements.
Scope position: Confirm the specific activity against Accreditation Schedule 1225009B at pre-engagement.
