Sister Pat Robb, CJ, who took part in the lobby, said: "The poorest for whom life is already a real struggle will bear the brunt of climate change, while those that have consumed more than their fair share of the earth will not have to pay such a heavy price.
"We have to remember that the earth was given to us by God to feed us all, in return we must love and care for it. That is why as a religious community we feel it is our obligation to lobby our MPs on this important issue."
The lobby was organised by the Catholic Agency for Overseas Development (CAFOD), the Conference of Religious (CoR) and the Justice, Peace and Integrity of Creation Links (JPIC).
The religious lobby is specifically calling on MPs to strengthen the Climate Change Bill by increasing the carbon emissions reduction target from at least 60% to at least 80% by 2050, and including the UK's share of emissions from international aviation and shipping in the reduction.
Hilary Benn MP, Secretary of State for the Environment and Rural Affairs met a delegation to hear their concerns later in the afternoon.
Cormac Cardinal Murphy-O'Connor, Archbishop of Westminster, sent a message of support, saying: "I am greatly encouraged to know that so many Religious have made their way to the Palace of Westminster. Today, there is an opportunity to persuade politicians of the importance of strong action to combat climate change. People living in poverty, who have done least to cause climate change, are already suffering its effects.
"We are all called to care for creation, living simply and sustainably, and to work for justice in solidarity with those living in poor countries. "
In 2005, CAFOD worked with religious orders to organise hundreds of religious from Roman Catholic and Anglican orders to lobby their MPs as part of the Make Poverty History campaign.
