Update Total Emissions Data by State (Including Categories)

[vkoves]

Currently our emissions data (nationally and for each state) only goes up to 2018, which means that we're missing three full years of emission data. We should either find a data source that we can use that is more up to date or a way to calculate the emissions data ourselves from the underlying data.

From the source page on wri.org (https://datasets.wri.org/dataset/climate-watch-states-greenhouse-gas-emissions):

Climate Watch U.S. States GHG Emissions data are derived from the State Inventory Tool (SIT) of the U.S. Environmental Protection Agency (EPA). https://www.epa.gov/statelocalenergy/state-inventory-and-projection-tool. The data include GHG emissions from all sectors for all 50 U.S. states and District of Columbia, and have a 2-3 year lag.

So there may not be anything we can do about getting more data, other than waiting for the EPA to update it next

The EPA has a Draft Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2020 report with national emissions data thru 2020, which looks to have state by state data as well (though couldn't find a total table of emissions per state):

This is currently causing an issue with our main emissions & projection chart with missing data for 2019, 2020 and 2021:

Table 1 has data per state for each year up to 2019

@SuragNuthulapaty thank you for sharing this. EIA has indeed published emissions data for 2019. However, this data does not have the sub-category breakdowns we have in our original source.

Updated EIA data: https://www.eia.gov/environment/emissions/state/
Source data from World Resources Institute (WRI): https://datasets.wri.org/dataset/climate-watch-states-greenhouse-gas-emissions

I emailed Johannes Friedrich (WRI dataset author) to see when the next version is coming out.

I emailed Johannes and Mengpin the launched website and asked for an update on the data. They say the 2019 data will be available in mid-August

Derek has emailed the WRI folks repeatedly, most recently on January 30th, and they haven't updated the data 😢
