Plans submitted by 146 countries to cap greenhouse gas emissions do not go far enough to keep global temperatures from exceeding the danger threshold, the United Nations said.
Pledges, submitted by all developed nations and three-quarters of developing countries, deliver "sizable" emission reductions and slow emissions growth in the coming decade, but they will not be sufficient to reverse by 2030 the upward trend of global emissions, the UN's climate change secretariat said in a report released in advance of a global climate summit.
The plans, known as "intended nationally determined contributions" (INDCs), are intended to be used as building blocks for the UN's World Conference on Climate Change in Paris beginning Nov. 30, when participating countries hope to finalize a global pact.
