LONDON (Reuters) - Greenhouse gas emissions in 2020 could be between 8 billion and 13 billion metric tonnes (14.33 billion tons) above what is needed to limit global warming to two degrees Celsius, a United Nations' Environment Program (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.
