Methodology
To identify the companies emitting the most greenhouse gasses, 24/7 Wall St. looked at the top 100 companies that produce the most CO2 equivalent emissions from the Political Economy Research Institute Greenhouse Index for 2019, the most recent year available.
We also added from the report environmental justice measures that show the percentage of the population under the poverty line and the share of the population from minority racial/ethnic groups that are at risk of exposure to dangerous greenhouse gasses from these emitters. The industrial sector of each company and the share of emissions from a single facility also came from the report.
