Many people start exploring the world of corporate emissions by familiarising themselves with carbon footprints of well known companies.
It's to that end that we are making a free tool available to the general public, which enables anybody to compare two companies on a like-for-like basis.
All it takes is to select two companies and to click "compare" and the following chart and table appear with emission efficiencies, energy consumptions and waste generation:

Other non-profits such as the CDP used to offer this capability to the general public - however:
This is all cumbersome and we have greatly simplified the process using all the information we hold in our database.
Note that for free we expose only a fraction of our full database. We also only expose a Ton CO2/Turnover efficiency - while in fact, each sector has an optimal efficiency metric. Retail for example compares emissions on a Ton CO2/m2 or /ft2, raw materials manufacturing on a per Ton production basis (e.g. cement, steel).
We have these optimal efficiency metrics on our database - contact us if you need information about specific companies.
We hope you find this useful - enjoy!
