At a press conference with visiting Norwegian Prime Minister Erna Solberg, President Trump criticized the deal the US had signed up for in the Paris Agreement.
President Donald Trump said Wednesday that the USA could "conceivably go back in" the Paris climate agreement if a fairer deal was reached, though he gave no concrete sign that any such deal was being discussed at this stage.
The president emphasised that he is not going to let the Paris agreement deny the US competitive edge.
The Obama administration's Nationally Determined Contribution (NDC)-a published declaration submitted under the United Nations Framework Convention on Climate Change (UNFCCC)-says the US intends to achieve an economy-wide target of slashing greenhouse gas emissions by 26% to 28% below its 2005 level in 2025.
Trump's decision in June past year to pull the United States out of the landmark global accord has sparked a wave of anger and dismay at home and also a chorus of disapproval overseas.
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.
When announcing the exit, Trump kept the door open to rejoining the pact "on terms that are fair to the United States, its businesses, its workers, its people, its taxpayers". Then he launched into an unclear comparison.
The treaty takes a bottom-up approach, with each country making its own commitments towards reducing the release of greenhouse gas emissions, and preparing for climate change. "You never miss up on a good opportunity with good environmental standards", she said. The oil and gas sector constitutes about 22% of Norwegian gross domestic product. "They have tremendous hydro power, tremendous". In fact, USA hydropower generation was almost double that of Norway, which produced 143.4 TWh of hydropower in 2016.
The Washington Post reports President Trump on Wednesday boasted about the sale of F-52 fighter jets to Norway.
