What may be, size-wise, the largest petition ever handed in to any British Prime Minister will be presented at Number 10 Downing Street by Christian environmental campaigners tomorrow.

UK-based international development agency Christian Aid has said that the G8 agreement to halve carbon emissions by 2050 was a step in the right direction, but was not enough to halt global warming.

The leaders of the G8 nations must take decisive action to halt spiralling rises in food and oil prices and to increase aid to developing nations the Secretary General of the United Nations has said.

Pax Christi International has issued an open letter to G8 leaders meeting in Hokkaido, Japan, urging them to make renewed efforts toward the disarmament of nuclear weapons.

Spiralling food and oil prices dominated the first day of the G8 summit in Japan. The Prime Minister, Gordon Brown, arrived at the summit calling for the launch of a ‘global action plan’ to tackle rising food prices.

In the run up to the G8 summit in Japan, presidents of nine Catholic Bishops’ Conferences have called on G8 nations to honour their commitments to reduce global poverty and tackle climate change.

Targeted aid is getting good results in Africa, but the G8 are falling further behind on meeting their commitments, a new report from the organisation set up by U2 frontman Bono, has said.

The fight against climate change has been marked by broken promises and missed opportunities, say three European bishops in a letter to political leaders gathered at the United Nations-led talks on the Indonesian island of Bali.

Christian Aid will push for a follow-on agreement to the Kyoto Protocol to include large-scale financial support for developing nations from the rich industrialised world at the UN Climate Change Conference in Bali starting tomorrow.
