The U.N. Environment Program published a report Tuesday saying the door is closing on an easy way out of the climate crisis.
"Even if nations meet their current climate pledges, greenhouse gas emissions in 2020 are likely to be 8 to 12 gigatons of CO2 equivalent above the level that would provide a likely chance of remaining on the least-cost pathway," the report said.
European Commissioner for Climate Action Connie Hedegaard said the report shows that developing countries account for about 60 percent of the global emissions. This means the fight against climate change needs to extend beyond industrialized nations.
''This is yet another call for climate action which shows the world is not getting its act together fast enough," she said in a statement Tuesday.
UNEP Executive Director Achim Steiner said near-term delays in addressing climate change will lead to long-term challenges ahead.
Total greenhouse gas emissions in 2010, the last year for which data are available, was 50.1 gigatons of CO2.
