United in their determination to forge a meaningful agreement to combat climate change, they have backed plans for 10 billion US dollars Copenhagen Launch fund, which will be used to immediately assist the most vulnerable countries to the effects of global warming. The document commits all Commonwealth countries to the goal of an operationally binding agreement at Copenhagen and a full legally binding outcome no later than 2010..The Australian Prime Minister Kevin Rudd, who chaired the work of drawing up the communique, described it as a substantive document which would provide momentum and support for a substantial outcome in Copenhagen.The consensus agreement was also welcomed by the United Nations Secretary General Ban Ki-Moon and Danish Prime Minister Lars Rasmussen who will host the final UN talks on a new climate change meeting in seven days time.Mr Rasmussen said he was delighted that 90 world leaders had now agreed to attend in Copenhagen.
