The cap-and-trade plan has seen a number of changes since it was first adopted with fanfare in Sacramento last year. Work was briefly halted by a judge after environmental justice groups sued, arguing that cap and trade’s market would allow polluters to buy the right to pollute more by purchasing more allowances. This, they argued, would affect mostly low-income neighborhoods located near governed facilities.

The California Supreme Court in September ruled to allow work to continue on the regulations.

In response to the concerns about localized pollution increases, the board will vote Thursday on whether to adopt a new management plan, under which the air quality near power plants and other regulated facilities will be monitored by the board to see if any more pollution results from cap-and-trade.

“If so, we will take action to respond to those changes,” Young said.
