Pruitt, who as EPA chief successfully campaigned for the U.S.to quit the Paris climate agreement, was to leave Bologna, Italy, Sunday for a meeting with President Donald Trump, said a spokesman for the G-7 talks, Davide Russo.
"All countries and the European Union, but the United States, agree that the Paris agreement is the only mechanism to advance global action on climate change, that it's irreversible and non-negotiable", Canada's Environment Minister Catherine McKenna told reporters Monday.
Trump has sometimes dismissed man-made climate change as a hoax even though a United Nations panel of leading scientists says it is at least 95 percent probable that man-made emissions were the main cause of warming since the 1950s.
Before his departure, Pruitt's counterparts from Britain, France, Germany, Canada, Japan and Italy expressed their disappointment at President Donald Trump's recent decision to pull the us out of the 2015 Paris Agreement. The coalition aims to uphold USA commitments under the Paris Agreement, and it also says it wants to meet or exceed the Clean Power Plan, an Obama-era EPA rule on power plant emissions.
The G-7 environment ministers were expected to issue a concluding declaration Monday.
The G7 is made up Britain, Canada, France, Germany, Italy, Japan and the United States, the world's seven biggest economies when the club was formed.
Pruitt heads the Environmental Protection Agency for Trump, who recently announced his decision to withdraw from the Paris climate deal.
With the environmental movement galvanized, and this new coalition of states, cities, and industries more energized than ever before to commit to mitigation efforts, we might see the United States bridge that gap even faster outside Paris. Any new USA administration could rejoin within 30 days, Kerry said. He has long rejected the scientific consensus surrounding climate change and earlier this year called America's Paris pledges "just a bad deal".
Pruitt made a habit in recent months of saying there is a US trend toward lower emissions from a peak in 2007, thanks to the glut of fracked natural gas pushing out coal as a source of electric power.
Patricia Espinosa, the United Nations official in charge of implementing the Paris accord, stressed that Trump's pullout would not make any difference in the short-term.
Germany and California, the US's wealthiest state, agreed Saturday to work together to keep the Paris accords on track. Numerous countries, American citizens, and major corporations such as Apple and Tesla all agree that withdrawing from the Paris Agreement is a bad idea; and cost-benefit analysis wise, Trump's promise is a promise with more costs than benefits.
Trump calls the pact unfair to the USA, saying it would hurt the economy while doing next to nothing to prevent global warming. The statement says that the Paris agreement remains as the global mechanism to effectively and urgently handle climate change and for the adaptation to its effects, while reiterating that it is irreversible and its comprehensive management is crucial for the security and prosperity of the world, societies and economies.
