The board’s vote Tuesday had support from Gov. Tom Wolf. The Democrat, however, isn’t taking a position on the petition itself.

The Clean Air Council, which submitted the petition, calls it a landmark step. The petition seeks to require polluters to buy permits for each ton of carbon they release.
