Trump is getting a variety of advice regarding the climate deal reached during President Barack Obama's administration, officials said.
While the rest of the world waits, Trump, who calls climate change a hoax perpetrated by China has said he will make his decision before the next G7 meeting on May 26-27 in Sicily.
Espinosa refused to comment on the impact of a possible US withdrawal from the talks or even the entire climate change accord.
Trump's inner circle has been tasked with providing the president, who has flirted with ditching the landmark agreement, with a range of policy options.
The Paris Agreement (French: Accord de Paris) is an agreement within the United Nations Framework Convention on Climate Change (UNFCCC).
The United States is the world's no. 2 carbon polluter, after China.
"It's in this sense that staying in and misbehaving has the potential of being worse than a clean pullout", he said.
Trump has recently delayed a decision to withdraw from the Paris Agreement, which asks participating countries to do things like cut greenhouse gas emissions so the global average temperature doesn't rise too much.
U.S. President Donald Trump said last month on his 100th day in office that he would make a "big decision" on Paris within the next two weeks.
A White House official says the meeting is expected to convene Tuesday afternoon.
Numerous speakers at a plenary session Monday said that the deal can not be "renegotiated", a proposal of Trump's Energy Secretary Rick Perry.
A White House spokeswoman confirmed that the meeting is being rescheduled.
Some senior members of the Trump administration - including the president - have questioned the validity of climate science in the past.
Regardless of whether or not the US leaves the Paris agreement, American climate scientists who doubt their work will find traction on this side of the Atlantic have an ally on the continent.
Under the agreement, the US pledged to cut its greenhouse gas emission by 26 to 28 percent from 2005 levels by 2025.
The former president said climate change "is already making it more hard to produce food".
The Trump administration has already proposed slashing funds for United Nations climate bodies, including the UNFCCC secretariat under whose auspices the negotiations take place.
