Closing arguments have been filed this week, and now it's up to New Mexico regulators to decide whether to adopt more rules aimed at capping greenhouse gas emissions across the state.
The New Mexico Environmental Improvement Board on Dec. 6 will consider a petition from New Energy Economy.
The environmental group wants the board to adopt regulations that would force large polluters such as power plants and refineries to reduce their greenhouse gas emissions by 3 percent per year from 2010 levels.
Critics contend the proposal would be costly, but supporters say the plan includes a limit on the amount companies would be required to spend to control emissions.
Earlier this month, the board approved regulations clearing the way for the state to participate in a regional greenhouse gas cap-and-trade program.
