The outgoing United Nations climate chief says he no longer expects the world to agree to sufficient cuts in greenhouse gases by 2020.
Yvo de Boer told reporters in Bonn that he doesn't see the UN's negotiation process for climate goals "delivering adequate mitigation targets in the next decade".
He says, however, that he foresees adequate long-term targets because industrialised countries have said they favour cutting emissions by 80 percent by 2050, and developing countries have also pledged to contribute.
De Boer says commitments by industrialised countries so far amount to 13-14 percent in emission cuts, although scientists say they should be 25-40 percent below 1990 levels by 2020.
