I am working with some data that express the environmental byproducts for the manufacturing of specific broad product categories (e.g. milk, soap, leather). The statistics are given per dollar of producer price, e.g. 1$ of soap products results into 0.1kg of CO2 emissions.
I was wondering, where can I find the average producer price for the relevant product categories, so that I can roughly calculate for example how much CO2 emissions are emitted in average for 100g of soap products?
