In the new study, we have analyzed 20 years of aviation emissions, up until and including 2018. Net warming from NO x emissions is a sum over warming (short-term ozone increase) and cooling (decreases in methane and stratospheric water vapor, and a long-term decrease in ozone) terms. For 2018 the net aviation ERF is +100.9

The California Air Resources Board released GHG emissions data for 2018 showing that emissions remain below 1990 levels but are effectively flat compared to 2017, while the economy grew by 4.3%. Total statewide 2018 GHG emissions were 425.3 million metric tons between 2017 and 2018, the first such decline since 2013.

The study focuses on the period between 2005 and 2018 and tracks combustion emissions of various polluting compounds from various sectors, looking at every state in the contiguous United States, from season to season and year to year. They first obtained emissions data from each of seven sectors for the years 2005, 2011, and 2018.
