Virginia's membership in RGGI was accomplished by the legislature and cannot be undone by administrative action.  The funds generated by RGGI are critical to supporting low-income energy efficiency programs - where the biggest "bang for the buck" can be accomplished in terms of reducing CO2 emissions.  New Jersey left RGGI in 2012 and re-joined in 2020.  A study published in December 2020 concluded "With regard to state specific findings, this study concludes that overall, New Jersey’s
withdrawal from the RGGI in 2012 reduced state revenue and led to higher emissions. "  https://stockton.edu/hughes-center/documents/2020-1215-rggi.pdf  Leaving RGGI is a bad idea and I urge you not to act upon it.
