CarbonSutra API calculates the carbon emission footprint for your organization. Hosted at ZYLA, it can be instantly tested by yourself at no cost.
This API is used to calculate emissions when the specific make and model of vehicle is not known. It can take a generic type or size of a vehicle as its input. For example, a car could be of small size, medium, average or large. Alternatively, a car could be of mini, sports, a 4x4 or a MPV type.
The same API extends to travel by motor bikes, buses, trains and taxis. Because of its flexibility, it is used to calculate the footprints of commuting and business travel via these modes. Along with this category of vehicle and the distance travelled in either miles or kilometers, the emission is calculated.
For Scope 1, this should be used to report travel in vehicles that are owned or controlled by the reporting organization. If not owned/controlled by organization, the vehicle's emission is reported under Scope 3.
The Approach
We use emission factors, data, guidelines from sources like UK Government GHG factors, US Department of Energy, US Environmental Protection Agency and UK Society of Motor Manufacturers and Traders.
The API to calculate the emission is simple: it just takes the category of vehicle based on its type or size, the type of fuel that is used and the distance travelled in either miles or kilometers.
WTT (well-to-tank) emissions consist of all processes between the source of the fuel (the well) through the extraction, processing (refining), storage and delivery phases up until the point of use (the tank) in the vehicle. Using the "include_wtt" field will add the associated upstream emission.

Prices are based on a recurring monthly subscription depending on the plan selected โ plus overage fees applied when a developer exceeds a planโs quota limits. In this example, you'll see the base plan amount as well as a quota limit of API requests. Be sure to notice the overage fee because you will be charged for each additional request.
