BOSTON — Senate President Stan Rosenberg is asking federal energy regulators to take into consideration Massachusetts efforts to reduce greenhouse gases as they review a proposed natural gas pipeline.

In a letter to Federal Energy Regulatory Commission Chairman Norman Bay, Rosenberg said he's concerned that the planned natural gas pipeline through southern New Hampshire and western Massachusetts by Kinder Morgan Inc. could set back those efforts.

Rosenberg pointed to the state's 2008 Global Warming Solutions Act, which calls for reducing greenhouse gas emissions between 10 percent and 25 percent below 1990 levels by 2020.

In the letter, Rosenberg said the state is instead trying to increase the availability of solar power, off-shore wind turbines, hydropower and other technologies to meet future energy demand.

FERC is currently accepting public comment on the project.
