Greenhouse gas emissions in 2020 could be between 8 billion and 13 billion tonnes above what is needed to limit global warming to two degrees Celsius, a United Nations' Environment Programme (UNEP) report showed on Wednesday.
The annual report, prepared by UNEP and the European Climate Foundation, studied a range of estimates to assess whether current pledges for emissions cuts are enough to limit the worst effects of climate change.
It found the gap between countries' emissions cut pledges and what is needed to stay under what scientists say is the limit to avoid devastating effects from global warming has widened since last year's estimate of 6-11 billion tonnes due to higher-than-expected economic growth and other new data.
The World Bank warned this week that the world is likely to warm by 3-4 degrees by the end of the century and extreme weather will become the "new normal", affecting every region in the world.
