CO₂ Emissions

MRS can enrich each brand match with an estimated carbon footprint for the transaction. When enabled, the response includes a spend-based emission rate, a qualitative impact band, and a human-readable

Response fields

The following fields are added to the brand object:

Field	Type	Description
co2EmissionsRate	number	Spend-based emission factor for the matched category, expressed in kg CO₂e per € spent.
co2EmissionsImpact	string	Qualitative impact band indicating the relative emissions intensity. One of low, medium, high and very high.
co2EmissionsReasoning	string	Human-readable explanation of the main sources of emissions for the category.

Example

{
  "brand": {
    "name": "Example Merchant",
    "brandCategoryType": "beauty_salon",
    "co2EmissionsRate": 0.12,
    "co2EmissionsImpact": "low",
    "co2EmissionsReasoning": "Treatment rooms require continuous heating. Single-use needles, oils, and consumables used carry their own manufacturing and disposal footprint."
  }
}

A high-impact category, such as an airline, returns a higher rate:

{
  "brand": {
    "name": "Example Airways",
    "brandCategoryType": "airline",
    "co2EmissionsRate": 2.5,
    "co2EmissionsImpact": "high",
    "co2EmissionsReasoning": "Flying burns large amounts of jet fuel on every journey. Onboard heating, lighting, catering, and entertainment add further energy consumption throughout."
  }
}

The surrounding brand structure above is illustrative; the CO₂ fields are appended to the brand object your integration already receives.

Behaviour

CO₂ data is returned according to the matched category:

Scenario	CO₂ fields returned
A brandCategoryType is matched	Yes - the rate, impact, and reasoning for that category.
No brandCategoryType is matched	No CO₂ fields are returned.
A virtual brand is matched with an MCC	Yes - the CO₂ fields mapped to that MCC.
The brandCategoryType is an other … type	No CO₂ fields are returned.

Localisation

co2EmissionsReasoning is returned in English by default.

If a localised version is configured for your account, the reasoning is returned in the language supplied on the request when that language is one of:
