Carbon-cutting pledges from 146 nations are “far from enough” to stave off dangerous global warming, the United Nations has warned. The voluntary efforts to curb greenhouse gases – if respected – would only yield a third of the cuts needed by 2030 to keep Earth from overheating, according to a UN Environment Programme report.
Countries have made “an historic level of commitment” with their pledges, UNEP executive director Achim Steiner said. “However, they are not sufficient to limit global temperature rise to the recommended level of 2°C this century.”
