The London event will start at Grosvenor Square at 12 noon. Beforehand, there will be a climate protest bike ride starting from Lincoln's Inn Fields at 10.30 am.
The march this year is part of a global day of action. You can read more about it here.
Speakers at Parliament at the end of the march will include Caroline Lucas (our party leader), Michael Meacher (ex-Environment Minister) and George Monbiot (Honorary President, Campaign against Climate Change).
The March on Parliament has four main themes:
1) No to a 3rd runway at Heathrow (the cabinet has postponed a decision on this until January 2009)
2) No new coal-fired power stations
3) No expansion of agro-fuels (which have a negative impact on climate and the world's food supply), and,
4) Yes to a renewable energy revolution and green jobs - a "Green new Deal"
