This map was made using data from Auto Alliance for 2018. The automobile industry has been reducing carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) emissions steadily on new car models year after year. This is why newer cars generally not only pollute less but also cause less global warming than older models.
Petroleum consumption per capita in litres per day (2018)
Average exposure to fine particulate matter (PM2.5)
This map is based on the data from America's Health Ranking, itself based on data from the U.S. Environmental Protection Agency. It shows the average exposure of the general public to particulate matter of 2.5 microns or less measured in micrograms per cubic meter (3-year estimate, 2017-2019).
Natural gas consumption per capita in cubic metres per year (2018)
This map is based on the data from the EIA for 2018.
