As it gathers data from worldwide sources, this spreadsheet is not a set answer which should drastically impact your diet. Depending on the region where you live and the farming practices which the product you buy supports, the numbers may greatly vary.

We will here be able to compare the overall CO2 emissions, the land use, the acidification<ref name=acid />, the eutrophisation<ref name=eutro /> as well as the water scarcity impacted by the 40 most produced foods in the world. These numbers, gathered from the largest database to date: 40,000 farms, across 119 countries include high impact industrials as well as small scale, organic or bio dynamic farms.
This comparative spreadsheet is based on 2 documents<ref>A graph and a spreadsheet, to be downloaded in the “Links & Details” section</ref> included in the research study titled “[https://science.sciencemag.org/content/360/6392/987/ <i>Reducing food’s environmental impacts through producers and consumers</i>]” published by J.

These numbers, gathered from the largest database to date: 38,700 farms, across 119 countries includes high impact industrials as well as small scale, organic or bio dynamic farms.
This study includes all data from farming to point of sale (meaning that it takes the whole food chain (including waste) into consideration).
 
We greatly recommend reading the document in its entirety (see download link below — 6 pages).
