OMA TECHNOLOGY · CALCULATOR

The emissions calculator with OMA technical backing.

OMA engine on GHG Protocol Brazil v1.0.1. Embeddable on events, sites, kiosks. Multi-language · Branded theme · No app, just a browser.

TECHNICAL BACKING

Why the OMA engine matches the FGV spreadsheet.

Built directly on the official Brazilian methodology. Every technical decision documented, every factor traceable.

METHODOLOGY

GHG Protocol Brazil v1.0.1

Closed version from FGV/Brazilian Program. Same factors that run in the official spreadsheet — tested divergence < 0.1%.

GWP

IPCC AR5

CO₂=1, CH₄=28, N₂O=265. Multi-gas separated by source. Biogenic CO₂ reported outside the tCO₂e total (Table 8 col BF).

BRAZILIAN FUELS

Fossil / biofuel split

Brazilian gasoline (E27.5) and diesel (B14.4) calculated by splitting the fossil from the biofuel fraction with per-gas factors. Updated to current ANP mandate.

REPRODUCIBILITY

Immutable FormulaVersion

Every calculation stores the formula version used. If you inventoried under v1.0.0, you can reproduce the same number years later with zero drift.
