The dataset is for research purposes only, and is not indicative of Amazon’s business use for carbon footprinting.
The dataset consists of retail products mapped to North American Industry Classification System (NAICS) codes. The mapping was done with Amazon Mechanical Turk, aggregating ground truth from 5 annotations per product. The dataset is the basis of estimating the carbon emissions of a product using Economic Input-Output Life Cycle Assessment (EIO-LCA). Dataset is stored as a Pandas dataframe.
