On September 7, the New Hampshire state Senate failed 15-9 to obtain the two-thirds majority needed to override Gov. John Lynch’s (D) veto of legislation pulling the state out of the Regional Greenhouse Gas Initiative (RGGI). New Hampshire’s House has twice passed, by margins much larger than two-thirds, bills mandating the state’s exit from the RGGI. Instead of full repeal, the Senate amended a bill passed by the House to alter the terms of the state’s RGGI participation, and mandates withdraw if other states do so first.
