By Laura O’Neil The US is on track to exceed its 2005 carbon dioxide emission limit by more than half before 2020, a report released by the US government showed.
The US has already surpassed the maximum global emissions limit of 450 gigatons of CO2, a measure of the amount of CO3 in the atmosphere, which is set to reach 800 gigatonds by the year 2100, and the new report said the current pace of CO 2 emissions was not sustainable.
“The rate of increase in CO 2 pollution from US sources is projected to reach a record high by 2030,” the report said.
“By 2020, the United States will be emitting more than twice as much CO 2 than in 2005.”
The US will surpass the maximum international limit of 400 gigatond CO2 emissions by 2020, but the report found that emissions could continue to increase.
The report from the US Energy Information Administration (EIA), released on Wednesday, also said the US would have to meet a target of reducing CO2 by 30 per cent by 2050, a goal that would require the US to increase its emissions by 20 per cent per year.
The new report comes as the US faces pressure to reduce its emissions as the world is facing its first cooling of record, and it has been widely criticised for its emissions.
“If we’re going to cut emissions, we’ve got to start now,” said Jennifer Francis, an energy analyst at the Natural Resources Defense Council (NRDC).
“We’ve got no choice.”
The US Energy Department said it had been working on the report for the last few years and was looking forward to publishing it in April.
“We have an ambitious plan to reduce emissions from US power plants by 30 percent below 2005 levels by 2030, with a goal of reaching that goal by 2020,” the department said in a statement.
Scientists at Yale University, in an analysis released last month, said that the US is not making a significant progress in meeting its emissions targets and that the country was “going backwards”.
“The US emissions problem is real, it is real right now, and there is no real plan to get us there,” said Nicholas Stern, a professor of atmospheric science at Yale.
While there is a global consensus on reducing CO 2 levels, some scientists argue that the world should be focused on getting the world to a global agreement on limiting emissions.
“We need to be focused now on the next generation of technology and the way we are going to manage our own emissions in the future,” said Jonathan Perrin, a climate change scientist at the University of Queensland.
“And the key thing is to make sure we are taking action now.”
Climate scientists said that as the climate warms, CO 2 will become more and more of a factor in the global climate system, leading to increased impacts.
A number of studies have shown that climate change is already impacting human society.
Scientists from the University and the University at Buffalo found that a study from the Yale University had found that people in low-income households living near polluted areas experienced more chronic illness and poorer health than people in more affluent areas.
