State-level CO2 emissions

Many data series in FRED are versatile enough to be viewed in different ways. We’ve offered two perspectives so far on CO2 emissions at the national level. Today, we offer another perspective—emissions at the state level—thanks to GeoFRED. The map above shows total emissions for each continental U.S. state. These numbers depend on the number of residents, types of economic activity, and types of fuel used. So it’s no surprise that the most populous states are the ones emitting the most carbon dioxide, with the possible exception of Louisiana.

Emissions from coal show something different. For example, the largest state, California, actually has one of the lowest coal-related emission levels. The relatively smaller states of Michigan, Missouri, and West Virginia, on the other hand, rank among the highest in coal-related emissions, which is a reflection of the fuel these states use for power generation.

Emissions from natural gas complement those from coal: That is, states with surprisingly low emissions from coal have higher emissions from natural gas (and vice versa). Louisiana has high emissions from natural gas, just as it does from petroleum, which is shown in our last map. While petroleum is used all over the country for transportation, extracting and refining it also requires a lot of petroleum, hence the higher emissions in oil-producing states.

How these maps were created:The original post referenced interactive maps from our now discontinued GeoFRED site. The revised post provides replacement maps from FRED’s new mapping tool. To create FRED maps, go to the data series page in question and look for the green “VIEW MAP” button at the top right of the graph. See this post for instructions to edit a FRED map. Only series with a green map button can be mapped.
