Classifications ADD-ONADD-ON
Many sources link emission factors (opens in a new tab) to specific industry classification schemes, and Climatiq makes it possible to select an emission factor based on these industry classification codes. Please see below the list of mappings we currently support, with the datasets that are mapped directly to them (note that the API will also map factors indirectly via the UN correspondence tables (opens in a new tab)):
For a more in-depth view on how Climatiq works with classification schemes, view the classification guide.
Estimate
POST Calculate total estimated emissions produced for a particular activity, as described by an industry classification scheme such as ISIC (opens in a new tab) or NACE (opens in a new tab). All requests are performed by sending a POST request to the following endpoint:
https://api.climatiq.io/classifications/v1/estimate
This endpoint lets you specify an industry classification code and have Climatiq automatically select the appropriate emission factor.
One industry code might be linked to more than one emission factor. If that happens, Climatiq will automatically select the most conservative emission factor.
If you would like to specify exactly what emission factor to use, you can specify other attributes to filter on, such as year
, source
or region
.
Industry classification codes can also be mapped to each other using the UN correspondence tables (opens in a new tab), allowing Climatiq to return emission factors from other classification schemes that represent the same activity if there isn't one found directly; this may happen for example because of different classification taxonomies being used in different geographies or by different data sources.
As with any estimation endpoint, the emission factor must be provided with parameters, such as weight, volume, energy. These are provided through the parameters
field. See the estimate endpoint for more details on how parameters and units work.
Request
This endpoint accepts the following parameters:
- classificationrequired object
A selector with classification data
classification.classification_coderequired stringThe classification code.
classification.classification_typerequired stringThe classification scheme; currently supported are
nace2
,isic4
,mcc
,naics2017
, orunspsc
.classification.data_versionrequired stringThe required Data Version string for this request.
classification.sourcestringEmission factor data source name.
classification.source_datasetstringThe name of the dataset the source published this emission factor under.
classification.regionstringGeographic region to which the emission factor applies.
classification.region_fallbackbooleanSet this to
true
if you're willing to accept a less specific geographical region than the one you've specified. Climatiq will then attempt to fall back to the larger region if it does not find any emission factors with the initial region. Only one fallback can be specified at a time. Default isfalse
Default Valuefalse
classification.year_fallbackbooleanSet this to
true
if you're willing to accept a less specific year than the one you've specified. Climatiq will then attempt to find an emission factor with a year as close as possible to the one you've provided. Only one fallback can be specified at a time. Default isfalse
Default Valuefalse
classification.yearintegerThe year in which the emission factor is considered most relevant, according to the source.
classification.source_lca_activitystringThe Life Cycle Assessment (LCA) activity to which this factor is associated.
classification.calculation_methodstringThe calculation method that will be used to calculate the CO2e emission factor. Learn more about calculation methods here.. Valid values are
"ar4"
,"ar5"
or"ar6"
classification.allowed_data_quality_flagsarray of stringsA list of data quality flags that you are willing to allow for this estimate. See the guide on data quality flags for more information and defaults. You can supply an empty list
[]
if you only want to accept emission factors without detected data quality issues. - parametersrequired Parameters object
Emission factor parameters. The parameter object changes depending on the EF selected.

Response
This endpoint returns an EstimationWithSourceTrail, which includes the total amount of emissions in kgCO2e
and the emission factor used to calculate the emissions.
- EstimationEstimationWithSourceTrail object
An object that describes the total amount of co2e and the emission factor used.
