Thousands marched through London in a protest which ended at the US embassy.
Dozens of protesters marched to the Scottish Parliament in Edinburgh via the Royal Mile.
The marches coincide with UN climate talks in Canada attended by Environment Secretary Margaret Beckett and Environment Minister Elliott Morley.
