Action Items

  • Go through the Proposed Emission Projection Methods table and do the following in a copy of your own in Yellow:
    • Rank the source categories by priority with 1 being the highest and 3 being the lowest
    • Comment "Yes" to source categories you believe have potentially significant COVID impacts - or remove any existing "Yes" identifier if there's no potentially significant impacts
    • Provide comments on recommended methods/data to develop the 2022 emissions and any additional input on the above entries
  • For reference, the summaries of the methods used to adjust historical years reflect the following previous modeling platforms:
    • 2016v1 – methods that were generally used to grow 2014 emissions to 2016 (see column H)
    • 2016v3 – methods that were generally used to back-cast 2017 emissions to 2016 (see columns I thru K)
    • 2019 – methods that were generally used to grow 2017 emissions to 2019 (see columns M thru O)
