Emission categories consist of multiple categories. Emission categories are used to classify types of goods and services. This is a way of categorizing goods and services in a generic way across the world. These emission categories allow us to use a large database of emission information to base our calculations upon. If you are an administrator and need to connect an emission category to a custom made expense type. Make sure you select an emission category with a title that is as close as possible to the expense type you want to connect it to.
