Contrary to popular belief, the United States has not pulled out of the Paris climate accords. But President Donald Trump’s first opportunity to do so is approaching — and he should seize it.

Trump pledged during his campaign for president to remove the United States from the Paris agreement. He has said repeatedly he will do so.

About 200 countries signed on to the Paris accords, which were negotiated during 2015. There was enormous pressure from the United States, under then-President Barack Obama, for an agreement and for other nations to be signatories.

In fact, as you may recall, this country agreed to participate solely because of an executive order issued by Obama. Though treaties with other nations are required by the Constitution to be approved by the U.S. Senate, Obama never submitted it to that body. He understood that the duly elected representatives of the American people would not approve.

Provisions of the accords allow most countries to set their own targets for reducing carbon emissions. China, our most serious economic and military foe, in essence agreed that it would at some date in the future begin to reduce emissions.

But the United States was required by the accords to slash emissions immediately and dramatically, to the point our economy would have been put at a disadvantage.

Climate change is a concern, of course. But what our competitors would prefer not be made clear is that, virtually alone among industrialized nations, the United States has been reducing emissions and continues to do so at a rapid pace.

And, there is this: This country, from which about 15% of carbon emissions come, is not the world’s most serious climate change threat. China — at 30% — earns that title.

Americans will continue to make rapid, major strides in reducing carbon emissions. But holding us to the Paris accords would wreck our economy — while doing nothing about nations such as China and India, where carbon emissions continue to go up.

For most of his presidency, Trump could do nothing about the Paris agreement. One of its stipulations was that no nation could withdraw during the pact’s first three years.

The accords went into effect on Nov. 4, 2016. Trump should pull the United States out — now.
