 The main categories of impact covered in the dataset are as follows:
 
-- ir pollution provides a set of value factors to monetise the costs associated with six air pollutants linked to effects upon population health, agricultural productivity and other impacts. 
-- Land use and conversion provides monetary impacts for companies' roles in displacing “pristine land” for their operations. 
-- Waste attempts to quantify the impacts generated by companies through both their generation and disposal waste. 
-- Water impacts monetize both companies' water consumption and their pollutants covering 104 individual water pollutants.

 In order to fulfill their intended purpose, the value factors need to be matched with the raw quantitative environmental data which each value factor is intended to convert into monetary terms (the value factors are expressed as conversions to the US dollar).
