Environmental Protection Agency administrator Lisa Jackson says the Obama administration plans to take further action to combat climate change. She said the administration plans to further exploit natural gas while also investing in renewable energy, has provided the necessary permits to facilitate offshore wind projects, and lauded Massachusetts for taking a leading role in trying to reduce the dangerous greenhouse gases that trap heat in the atmosphere. “This administration hasn’t backed away from the need to address climate change, carbon pollution, and other forms of pollution, even as we’ve been growing our economy and trying to add jobs,” she said.
