Energy Endpoint version: V1V1 ADD-ONADD-ON

To see the changes since the preview versions, see our changelog

The energy endpoints automatically calculates the greenhouse gas emissions associated with the consumed energy based on relevant emission factors. These factors are determined based on the specific type of energy and the region where it is consumed, ensuring accurate carbon footprint calculations for your organization.

This feature can be used to help businesses estimate and report their scope 1, 2 and associated scope 3 emissions under the GHG Protocol. It also meets the requirements of the SBTi and covers market-based and location-based approaches for electricity use. The Energy Endpoint has passed a validation audit confirming compliance with the requirements of ISO 14067 and GHG Protocol - Product Life Cycle Accounting & Reporting Standard. Please see the Climatiq Trust page (opens in a new tab) for the document of conformity.

For extra information about our methodology for GHG Protocol scopes 2 and 3.3 calculation, please view the scope 2 and scope 3.3 FERA guides.

Electricity use

POST Calculate the estimated greenhouse gas emissions for electricity use, including both grid electricity and direct-line electricity. This endpoint allows you to obtain accurate carbon footprint calculations for your organization's purchased electricity.

IEA data

By default the Electricity calculator uses publicly published emission factors from various official sources covering 63 countries. For greater coverage and consistency you also have the option to purchase a premium license to emission factors from the International Energy Agency (IEA) increasing coverage to 149 countries.

Request

This endpoint accepts the following parameters:

Request parametersShould be sent as a JSON object in the body
    • regionrequired string

      The region or country where the electricity was consumed, usually a country but could be US / Australian / Canadian state / province or US eGrid. A US zip code can be provided in the format US-XXXXX or a UN/LOCODE in the format XX-YYY. See also choosing a region below.

    • yearinteger
      Default value: Latest year available

      The year for which the greenhouse gas emissions are being calculated.

    • amountEnergy object
      Default value: Sum of the components

      The total electricity used.

    • recsEnergy object

      Quantity of RECs (Renewable Energy Certificates) to apply.

    • source_setstring
      Default value: "iea" if the API key used has access to the premium IEA dataset, otherwise "core"

      Specifies which set of emission factors the caller would like to use. Valid values are core or iea

    • componentsarray of Component objects

      An array containing the different components of the electricity consumption and their associated details.

    • allow_iea_provisionalboolean
      Default value: false : no provisional IEA factors will be used

      When using the IEA source, which requires an IEA license, you can choose whether you wish to use provisional factors from IEA where final factors are unavailable.

An implied residual component will be added to make up any difference between the total amount of energy in the request and the sum of the amount of energy in each component.

Choosing a region

Regions are currently only available where grid emission data is available. We plan to expand this coverage over time. In countries where we have coverage, you can use a country-level region code to specify the country, or an extended region code to specify a subdivision, or a location within that subdivision. In the US the preferred method is to use a zip code in the format US-XXXXX in order to most accurately choose both eGrid and state-based factors.

The suggested way to find available regions is to make a request without setting a region and see which ones are indicated as being available in the error response.

Choosing a supplier

Suppliers are currently only available in US states and in the United Kingdom. The suggested way to find available suppliers's is to make a request without setting a supplier (but setting amount and region) and see which suppliers are indicated as being available in the error response.

Request

curl --request POST \
  --url https://api.climatiq.io/energy/v1/electricity \
  --header "Authorization: Bearer $CLIMATIQ_API_KEY" \
  --data '{
    "region": "US-CA",
    "components": [
        {
            "amount": {
                "energy": 0,
                "energy_unit": "kWh"
            },
            "supplier": ""
        }
    ]
}'

Response

The available suppliers will depend on the region.

Batch Heat and Steam Use

POST For bulk data-processing, this endpoint has a batch endpoint variant allowing for up to 100 calculations with one API call.

The batch endpoint is available at:

https://api.climatiq.io/energy/v1/heat/batch

Provide this endpoint with an array of objects, where each object is a valid body for the non-batch endpoint. See the batch endpoint documentation for more information about how batch endpoints work and how to handle errors.

Fuel Use

POST Calculate the estimated greenhouse gas emissions for fuel combustion.

https://api.climatiq.io/energy/v1/fuel

Request

The request to the fuel combustion endpoint accepts the following parameters included in the request body. Except for fuel_type and amount, which must match exactly, any parameters that cannot be matched to an emission factor will be ignored, e.g. this means that the emission factors might be for a different region than you selected. In the event of a mismatch, a notice will be included in the response.

Request parametersShould be sent as a JSON object in the body
    • fuel_typerequired string

      The type of fuel burned. See choosing a fuel_type for how to choose this.

    • amountrequired Energy/Volume/Weight object

      The amount of fuel burned.

    • regionstring

      The region or country where the fuel was burned.

    • yearinteger
      Default value: Latest year available

      The year in which the fuel was burned.

Choosing a fuel_type

The suggested way to find the available fuel_types is to make a request without setting the fuel_type (but setting amount and region) and see which fuel_types are indicated as being available in the error response. region can also be omitted to see all fuel_types available globally.

Request

curl --request POST \
  --url https://api.climatiq.io/energy/v1/fuel \
  --header "Authorization: Bearer $CLIMATIQ_API_KEY" \

        "weight_unit": "g"
    },
    "region": "US"

Response models

Response formats shared between the above endpoints.

Energy reporting quad

For electricity (market and location) and heat and steam, the API reports 4 estimates, one for scope 2 (consumption) emissions and each of the 3 scope 3.3 (FERA) emissions estimates:

AttributeTypeDescription
consumptionEnergy estimateEstimates of the greenhouse gas emissions that result from generating the consumed energy.
transmission_and_distributionEnergy estimateEstimates of the greenhouse gas emissions that result from generating the energy which is subsequently lost during the processes of transmission and distribution.
well_to_tankEnergy estimateEstimates of the greenhouse gas emissions that result from obtaining the fuel used for generating the consumed energy.
well_to_tank_of_transmission_and_distributionEnergy estimateEstimates of the greenhouse gas emissions that result from obtaining the fuel used for generating the energy which is subsequently lost during the processes of transmission and distribution.

Energy estimate

Response parameters
    • co2efloat

      The total greenhouse gas emissions associated with the consumed energy, expressed in kilograms (kg).

    • co2e_unitstring

      The unit in which the CO2e field is expressed. The value of this is always kg

    • co2e_calculation_methodstring

      Which calculation methodology that was used for the calculation. The value of this is either "ipcc_ar4_gwp100", "ipcc_ar5_gwp100", "ipcc_ar6_gwp100" or "ipcc_mixed_gwp100". Learn more about calculation methods here.

    • source_trailarray of Source Data Points

      An array of data points that help explain and provide trust in the calculation. Click to view more details about Source Trail.

    • co2_biogenicfloat or null

      The biogenic CO2 emissions associated with the consumed energy, expressed in kilograms (kg). This is not included in the co2e total.

    • constituent_gasesEnergy constituent gases or null

      Breakdown of the main 3 greenhouse gases which constitute the co2e estimate, they may not sum to the whole co2e value in the case of other, non-itemized gases. A null means the emission factor used only provided co2e without a constituent gase breakdown.

Absence of Estimation model

Our older calculation endpoints always return the Estimation model which gives information about the emission factor that was used in the calculation and how it was applied, but we haven't implemented that for our newest features. This is because the complexity of the calculations performed by our new emissions calculators means that we are unable to explain the calculations adequately using the estimation model. Below are the new features which replace the Estimation model and which we are trialing on the Energy feature. If you have some requirements for calculation transparency please get in contact (opens in a new tab).

Constituent Gases

AttributeTypeDescription
co2numberEstimation of kg of CO2 emissions for the activity
ch4numberEstimation of kg of CH4 emissions for the activity
n2onumberEstimation of kg of N2O emissions for the activity

Notice

The notices array can contain objects like these:

Notice attributesTypeDescription
severitystringEither warning or info. warning is for messages that might lead to inaccurate calculations. You should check these to make sure the results are fit for your intended purpose. info is for information that will help you understand the calculation result better.
messagestringAn explanation of the notice.
codestringA machine-readable categorization of the notice to allow automatic handling.

The different possible values for code are as follows. You should not treat this list as exhaustive as more values may be added with time:

For Electricity

Notice code valuedescription
supplier_mix_used_for_residualUnable to find a residual mix factor for the requested region, the supplier mix will be used instead, this will likely result in underestimating this portion of the energy usage.
global_default_wtt_usedApplying a global default well to tank percentage due to absence of an applicable emissions factor. For more accurate market well to tank emissions, explicitly provide a fuel mix.
ignored_parameterA parameter in the request was ignored in favor of some more precise piece of data
recs_subtracted_market_generationMarket components were subtracted for recs
recs_subtracted_market_transmission_and_distributionMarket T&D components were subtracted for recs
provisional_emission_factor_usedA provisional EF was used; the result may be inconsistent with, and significantly different from, results that use a final EF. If you don't want to use provisional EFs from IEA, add the flag "use_provisional_iea": false to your request

For Fuel Combustion

Notice code valuedescription
no_region_matchA different region was selected as the requested region was not available for the selected fuel type and unit.
wtt_not_estimatedFailed to estimate well to tank: a WTT factor wasn't found with the requested fuel type.
