The December 3rd, 2005 protests were not confined to the UK, but formed part of the first Global Day of Action on Climate Change, in which CCC played a key role in co-ordinating. The demonstrations, in more than 30 countries around the world, were timed to coincide with the crucial Montreal Climate talks in Canada, at which preliminary agreements were made for a post-Kyoto treaty to take effect after 2012. Outside Montreal itself, a crowd of between 25,000 - 40,000 gathered in a protest organized by the American-based Climate Crisis Coalition.
The December 2006 protests again had an international flavour, with the London, UK protest attracting 10,000 participants..
The Campaign against Climate Change has a network of local groups around the UK, which are currently in the process of being extended. On February 9th, 2008 the Campaign against Cliamte Change hosted a Trade Union conference on climate change. Over 300 delegates attended and heard speakers, including several Trade Union general secretaries or their deputies, from most of the major British unions. .
CCC is an example of a growing number of climate-related environmental pressure groups that have developed during the last decade, including organizations like Rising Tide, Climaction and the coalition group Stop Climate Chaos, of which the Campaign against Climate Change is a member.
