- •
We developed a framework for “Tier 3” estimates of N2O soil sugarcane soil emissions in the state of São Paulo – Brazil.
- •
We provided a framework for future development of “Tier 3” inventories for N2O agricultural emissions in Brazil.
- •
We compared this approach to IPCC's “Tier 1” approach.
- •
We used three different spatial resolutions to estimate N2O soil emissions.
- •
We found that results from “Tier1” and “Tier 3” methodologies differ significantly.
