Delegates agree to extend Kyoto at Doha climate summit

Delegates from almost 200 nations have agreed to extend the Kyoto Protocol at UN climate talks in Doha, Qatar.

The first commitment period under the protocol, which commits industrialised countries to reducing their carbon emissions, expires this year.

The extension will cover the interim period between the first commitment period expiring and a new international emissions treaty due to come into force in 2020.
