Separately regulated pollutants increase with transportation fuel economy policies #141

Closed mkmahajan closed 3 years ago

mkmahajan commented 3 years ago

Our Brazil partners pointed out that when you turn on a policy that increases transportation fuel economy, the EPS shows an increase in separately regulated pollutants like CO and VOCs. This is happening in the variable Transportation Pollutant Emissions Disaggregated where the Percent Change in Fleet Avg Fuel Economy is used to adjust Transportation Sector Fuel Used for separately regulated pollutants. We may need to modify the calculation approach to make sure we don't increase emissions above BAU.

I haven't assigned this a version number tag yet, since I think the priority level may depend on how easy a fix is.

Robbie just correctly pointed out that increasing fuel efficiency will cause people to drive more, which would in fact increase separately regulated pollutants. Sorry for the false alarm! I am closing this issue.
