Trump’s Next Step on Climate Change Reconsider the EPA’s labeling of carbon dioxide as a pollutant, based on now-outdated science. By Paul H. Tice

The executive orders on climate change President Trump signed this week represent a step in the right direction for U.S. energy policy and, importantly, deliver on Mr. Trump’s campaign promise to roll back burdensome regulations affecting American companies. But it will take more than the stroke of a pen to make lasting progress and reverse the momentum of the climate-change movement.

On Tuesday, in a series of orders, Mr. Trump instructed the Environmental Protection Agency to rework its Clean Power Plan, which would restrict carbon emissions from existing power plants, mainly coal-fired ones. Last year the U.S. Supreme Court stayed enforcement of the CPP pending judicial review.

Mr. Trump also directed the Interior Department to lift its current moratorium on federal coal leasing and loosen restrictions on oil and gas development (including methane flaring) on federal lands. And he instructed all government agencies to stop factoring climate change into the environmental-review process for federal projects. The federal government will recalculate the “social cost of carbon.”

These actions are a good start, but all they do is reverse many of the executive orders President Obama signed late in his second term. While easy to implement and theatrical to stage, such measures are largely superficial and may prove as temporary as the decrees they rescind.

Because they don’t attack the climate-change regulatory problem at its root, Mr. Trump’s orders will not provide enough clarity to U.S. energy companies—particularly electric utilities and coal-mining companies—for their long-term business forecasting or short-term capital investment and head-count planning.

To accomplish that, the Trump administration, led by EPA Administrator Scott Pruitt, needs to target the EPA’s 2009 “endangerment finding,” which labeled carbon dioxide as a pollutant. That foundational ruling provided the legal underpinnings for all of the EPA’s follow-on carbon regulations, including the CPP.

It also provided the rationale for the previous administration’s anti-fossil-fuel agenda and its various climate-change initiatives and programs, which spanned more than a dozen federal agencies and cost the American taxpayer roughly $20 billion to $25 billion a year during Mr. Obama’s presidency.

The endangerment finding was the product of a rush to judgment. Much of the scientific data upon which it was predicated—chiefly, the 2007 Fourth Assessment Report of the U.N.’s Intergovernmental Panel on Climate Change—was already dated by the time of its publication and arguably not properly peer-reviewed as federal law requires.

With the benefit of hindsight—including more than a decade of actual-versus-modeled data, plus the insights into the insular climate-science community gleaned from the University of East Anglia Climategate email disclosures—there would seem to be strong grounds now to reconsider the EPA’s 2009 decision and issue a new finding.
