Estimation
Many endpoints return one or more of the Estimation models described below. One Estimation model always uses one Emission Factor (opens in a new tab), but when doing complex estimations, it is often necessary to combine multiple emission factors. In cases like that, endpoints often return multiple Estimation models.
Estimation
The Estimation response model is returned in a variety of estimation-related endpoints.
The model contains the total amount of emissions in kgCO2e
, and includes the emission factor used for the calculation.

---|
co2e float Emission factor carbon dioxide equivalent. |
co2e_unit string The unit in which the co2e field is expressed. |
co2e_calculation_method string Which calculation methodology that was used for the calculation. Is always ar4 , ar5 or ar6 . Learn more about calculation methods here. |
co2e_calculation_origin string Whether or not the data source or Climatiq made the calculation. Is always source or climatiq . Learn more about calculation methods here. |
emission_factor used emission factor The emission factor that was used for the calculation. |
constituent_gases constituent gases Indicates which constituent gases the emission factor is composed of. |
audit_trail audit trail flag Indicates whether Audit trail was enabled for this request. Is one of enabled , disabled or selector . |
activity_data Indicates the parameters which were multiplied by the factor to estimate emissions. |

EstimationWithSourceTrail
The EstimationWithSourceTrail model is the same as Estimation, but includes an additional source_trail
field as well.
