What emissions data are available for 2018 and 2019?

EPA has NEI point source data for 2018 and 2019, available upon request by using the Contact Us form, and selecting "Point Sources."  Note that some of these sources reuse 2017 data by carrying it forward, but many sources have updated values in these interim year datasets.

Emissions inventories and other inputs for emissions modeling for 2018 and 2019 are available as part of EPA's modeling platforms.
