In this analysis, I examined recent changes in the contribution of transportation to total greenhouse gas emissions in the United States relative to the other sources of emissions (industry, commercial, residential, and agriculture). The examined data were for 1990 and 2017. Total emissions exclude emissions from U.S.

The authors used the VMT data to calculate that emissions of US greenhouse gas (GHG) emissions were reduced by 4% in total and by 13% from transportation in the almost 8 weeks since many stay-at-home orders went into effect. This puts the US on track to meet its annual goals for GHG reduction under the Paris Climate Accord.
