Are you thinking that the pandemic will have a larger effect than just a temporary drop in coal/oil/gas emissions?
It's impossible to predict to what extent, but I think it will have some negative affect beyond what has been projected in previous years.
I think it'll certainly reduce air travel for an extended period of time for business and personal travel, alike. I don't know what impact it will have on vehicle travel, particularly for domestic summer vacations, though I think it has accelerated the acceptance of remote working which reduces commuting (and resulting traffic) long-term, even accounting for the reduced usage of mass transit, especially in cities with strong transit systems (DC, NYC, Boston, Chicago, Bay Area, etc.). It should accelerate the decline of coal generation since that's the marginal generation source (though this won't happen as quickly in states outside of the ISO/RTOs, especially in the Southeast).
If more manufacturing becomes domesticated (or even if trade becomes more common with Canada & Mexico as opposed to China and the rest of Asia) then that reduces shipping, as well, which I'd argue more than offsets the increased industrial emissions.
Time will tell, though....
