The 194 nations meeting at the United Nations Climate Conference in Doha approved here Saturday the extension until 2020 of the Kyoto Protocol for controlling climate change, which was to expire this year, though some countries have pulled out of the deal.

After a day's delay and a night of intense negotiations, those attending agreed on a new 8-year period of commitment to the Kyoto Protocol - except for Japan, Russia, Canada and New Zealand.

The problem is that the countries committed to reducing greenhouse gas emissions during the second Kyoto period, headed by the European Union, Australia and Norway, are responsible for little more than 15 percent of the world's contaminant gases.

The United States never ratified the first part of the Kyoto Protocol, nor will it join in the second phase.

The World Wide Fund for Nature blasted Saturday's accord as a "weak and unreal" attempt to combat climate change.

The negotiators at Doha did not fulfill even the minimum expectations, the organization said in a highly critical communique, in which it also regretted that the summit "delivered no real cuts in emissions, it has delivered no concrete finance, and it has not delivered on equity." EFE
