President Trump will now wait until after the G-7 meeting in late May before making a decision about whether to keep the U.S. in the Paris climate agreement, his press secretary Sean Spicer said Tuesday.

The announcement pushed back a decision that has sweeping implications for the fate of global efforts to fight climate change – and has drawn intense interest from the international community, corporate lobbyists, and environmental groups.

Trump famously promised on the campaign trail to “cancel” the Paris agreement. But four months into his presidency, the Trump administration’s position on the historic agreement endorsed by over 190 nations remains in limbo, and it will send officials to three major international meetings without having a formal position on the accord.

A White House meeting on the agreement had already been postponed Tuesday – at least the second time a major meeting on the subject has been put off.

At the Tuesday briefing, Spicer was repeatedly asked by reporters about the Paris decision, and affirmed that Trump “wants to make sure that he has an opportunity to continue to meet with his team to create the best strategy for this country going forward.”

That team is comprised of clashing parties, including EPA administrator Scott Pruitt, who wants the U.S. to ditch the Paris agreement, and Secretary of State Rex Tillerson, who thinks the nation should remain a party and continue to negotiate with international partners about how to address climate change.

The delay means that the Trump administration will have to navigate three critical international meetings this month without formulating its position on climate policy: the current meeting in Germany, which is focused on implementing the Paris agreement, the Arctic Council meeting in Fairbanks later this week, where the changes in the ice cover will be on the agenda, and the G-7 gathering.

The Paris agreement has posed a problem to the White House because it is simultaneously non-binding and yet demands specifics. Each nation has to pledge how much it will cut its emissions, and it’s already clear the administration can’t meet the Obama-era pledge to cut emissions between 26 and 28 percent below 2005 levels by 2025.

So staying in the agreement would require revising that pledge downward, which would risk drawing international scorn. However, leaving the agreement altogether could potentially leave the U.S. isolated.
