Campaigners call for climate court

Participants in a conference on climate change are demanding 300 billion US dollars in annual compensation from wealthy countries and transnational companies to deal with the effects of global warming.

Leftist Bolivian President Evo Morales is leading the meeting of thousands of social activists and officials.

They proposed a reduction of greenhouse gas emissions by 5% by 2020 and the creation of a international climate court to penalise countries that don't reduce their emissions.

The conference was born out of opposition to the Copenhagen Accord brokered by President Barack Obama at a December summit that would raise nearly 30 billion US dollars over three years to help poor countries combat the effects of climate change.
