In a widely anticipated meeting, California regulators will begin to consider Wednesday whether and how to force the state’s major polluters to reduce greenhouse gas emissions under a key program.

Staff of the California Air Resources Board could signal at a special meeting how CARB will comply with a new state law requiring the agency to shape its carbon market policy toward achieving substantial emissions cuts.

CARB runs California’s carbon market — the largest in the U.S. — which sets a declining yearly limit on statewide greenhouse gas emissions.

The CARB staff is expected to discuss carbon market revisions that could pressure regulated entities to reduce emissions by making it more costly for them to pollute. The board itself is not expected to take action for months.
