The group of the seven largest industrial nations on Monday failed to affirm their commitment to the Paris climate change agreement, blaming the policies of President Trump.

It was "not possible" for the Group of Seven ministers to reaffirm their commitment to the Paris Agreement because the "U.S. administration is reviewing" its climate policy and emissions regulations, said Carlo Calenda, Italy's economic development minister, who is hosting the gathering of ministers in Rome.

Calenda said the discussion on climate change at the meeting was "very constructive with the U.S., there was no friction." He added that the G7 ministers "respect that the U.S. is re-analyzing its position."

The White House has not taken a position on whether it will withdraw from the Paris agreement. It intends to make its decision by the end of May. But Trump has issued executive orders that directly undercut actions taken by former President Barack Obama as part of the U.S. commitment to the Paris deal.

Meanwhile, the government's Energy Information Administration issued new data Monday that showed U.S. carbon dioxide emissions from the burning of fossil fuels fell 1.7 percent in 2016 from 2015. The agency said the drop in emissions follows a decade-long trend of lower greenhouse gas emissions.

Carbon dioxide emissions fell 14 percent from 2005 levels, even though crude oil and natural gas consumption increased, while coal consumption decreased.

Many scientists blame greenhouse gas emissions from the burning of fossil fuels such as crude oil and coal for driving manmade climate change.
