Washington observers say the Trump administration is planning to replace the EPA’s rule to limit emissions from coal-fired power plants with one that’s more industry friendly.

The Clean Power Plan written under former President Barack Obama required carbon emissions to be cut by 32 percent through improved efficiency and the use of more low-carbon power sources like natural gas and renewables. The plan is intended to combat climate change.

President Trump has called climate change a “hoax.” EPA chief Scott Pruitt has expressed skepticism about human activity – like carbon emissions – having an effect on the climate.

A new EPA proposal is expected to focus on improving the efficiency of coal-fired generators – which environmental groups say would achieve less of a reduction in carbon emissions. Additionally, the National Resources Defense Council (NRDC) said making coal plants more efficient would motivate energy companies to operate them more, resulting in an increase in emissions.

The replacement plans were first reported by Politico.
