This week, Virginia's State Air Pollution Control Board was in court asking the Virginia Court of Appeals to revive its ill-conceived plan to leave a pivotal climate change program, the Regional Greenhouse Gas Initiative (RGGI). A trial judge had earlier found the board's withdrawal to be "unlawful." With all due respect, the board should get out of the courtroom and back to a program that helps Virginians prepare for the extreme weather events we have witnessed in recent years. RGGI works by capping carbon pollution from power plants and then establishing a market to trade allowances under the cap. If power companies see ways to reduce pollution quickly, they make those cuts and earn credits to be sold. If they believe it is too cumbersome to slash emissions today, utilities purchase allowances instead. The market-based nature of RGGI reflects its bipartisan origins. It was launched in 2005 with an agreement signed by three Republican governors and four Democrats. Eleven states now participate.
