EPA chief vows to develop carbon rules based on science

In her first speech since being confirmed by Congress, Environmental Protection Agency chief Gina McCarthy pledged Tuesday to let science drive her agency’s agenda as it begins to develop controversial rules to limit carbon pollution from existing power plants.

Despite Washington’s partisan, fractured atmosphere, McCarthy said, “We are not going to stop looking at the science’’ in writing regulations limiting emissions that contribute to global warming. During the Bush administration, the EPA was routinely criticized by environmentalists for letting politics trump the growing scientific evidence of man-made climate change.
