Yesterday's budget was a missed opportunity for the government to show that it is serious about addressing the problem of climate change, which threatens the lives and livelihoods of millions of the world's poorest people, an aid agency has said.

UK government plans to spend £100 million over the next five years helping poorer countries deal with the impact of global warming is a welcome acknowledgement of the rich world's "carbon debt" obligation, says Christian Aid.

The international development agency Christian Aid has applauded the new package of environmental measures announced by the UK’s largest biscuit manufacturer, cutting its carbon emissions and reduce its use of water and packaging.

Christian climate campaigners have appointed an award-winning documentary maker as their lead campaign strategist. Mark Dowd, a former Dominican Friar and television producer / presenter, is to take up the post with Operation Noah.
