UN Climate Change Conference Closed

Meanwhile, although not legally binding, the accord now is open for signing. But what does the accord say about climate change?

Our correspondent Li Ningjng reports from Copenhagen.

The Copenhagen Accord recognizes the scientific view that an increase in global temperature below 2 degrees is required to stave off the worst effects of climate change. It specifies that industrialized countries will commit to implement, individually or jointly, quantified emissions targets from 2020, to be listed in the accord before 31 of January, 2010.

It also stresses the principle of "common but differentiated responsibilities", and that social and economic development and eradication of poverty are the priorities of developing nations. In addition, the Accord says, developed nations will support the goal of raising 100 billion dollars a year by the year 2020 to help developing nations pursue low-carbon development and deal with the impact of climate change.

During a press conference before he left Copenhagen Friday evening, the American president Barack Obama said, although they had failed to reach a legally binding document, at least they'd reached a meanful agreement, and had had a good start on tackling climate change.
