The exchange over the environment - and Solberg's efforts to make the business case for fighting climate change - stood out as the two leaders bonded over economic ties and military might. Trump also said he wished the USA could use hydropower."One of the great assets of Norway is a thing called water", he said.
"In November we started delivering the first F-52s and F-35 fighter jets", Trump said during a press conference with Norwegian Prime Minister Erna Solberg.
Last June, Trump angered global businesses and politicians by announcing the USA would be leaving the worldwide climate accord, which was signed by the Obama administration and counts every nation on earth as a signatory until the United States formally quits the deal in 2020. He also stated that the current agreement "took away a lot of [the country's] asset values".
The Obama administration's Nationally Determined Contribution (NDC)-a published declaration submitted under the United Nations Framework Convention on Climate Change (UNFCCC)-says the USA intends to achieve an economy-wide target of slashing greenhouse gas emissions by 26% to 28% below its 2005 level in 2025. Almost every other country in the world has signed the agreement.
This is not the first time Trump has hinted that the USA could rejoin the pact.
President Donald Trump says the economic ties between the United States and Norway are "robust and growing" and he's pointing to their work in the North Atlantic Treaty Organisation alliance to counter security threats. But he will have to wait until 2019 to formally notify the United Nations of a US exit under the agreement's regulations.
French President Emmanuel Macron in December said he would not agree to a renegotiation but was hopeful the U.S. would return to the accord.
Trump also sought to stress that his administration was a champion of environmental protection.
During the briefing, Trump appeared to stress that his administration is "very strong" on the environment.
"The Paris accord really would have taken away our competitive edge, and we're not going to let that happen", he said.
"I'm not going to let that happen", he added.
