Spend base -> emissions measurement model based on money spent on a purchase based on data with information on all products from all countries (ExioBase), (product input and product output). These EFs take into account the economic interactions between different sectors in different countries that will calculate the emissions per euro spent for each product. In Dcycle we work with a closed list of product categories with their respective EFs. Each sector has a specific product category code set at national, regional and national level. Each product has a SIC code (Most International Code), which is determined by the suppliers. From this code the emissions are calculated (concrete information document for the client on what he has to do, to know how each company has its information, in order to implement a good proposal).
Supplier Specific -> LCA, in which emissions are not based on price, but on the carbon footprint of the product.
If a customer wants to use supplier specific and has product HC calculated, what are the procedures to be able to use it in the purchase calculation?
Dcycle is not responsible for the data or the origin of the carbon footprint. If they have LCA results, they can be used, but in case of verification, they will be asked where the calculations come from.
