Charts are Always Great for Feeling Guilty

Environmental Working Group: The chart shows the lifecycle total of greenhouse gas emissions for common protein foods and vegetables, expressed as kilograms (kg) of carbon dioxide equivalents (CO₂e) per kg of consumed product. We compared our production emissions data for the main meat proteins to several mostly peer-reviewed or government-sponsored studies in the U.S. and Europe that assessed greenhouse gas emissions from animal production systems. Only a handful of other studies showed lower emissions, and these were within 25 percent of EWG’s figures, indicating that our results may be conservative.
