Faith leaders from across the religious divide will gather in Sydney to call on prime minister Scott Morrison to show moral leadership on climate change.
More than 150 religious leaders - including the heads of the Uniting Church in Australia, the Federation of Australian Buddhist Councils, Muslims Australia and the National Council of Churches - on Tuesday issued an open letter to Mr Morrison.
The letter calls on the prime minister to make addressing climate change his number one priority.
"The climate situation is much more than a political or even a scientific issue. It is a profoundly moral one," the letter says.
Under the banner of Australian Religious Response to Climate Change, the group calls for a stop to new coal and gas projects, stopping Adani's controversial coal mine in central Queensland and moving to 100 per cent renewable energy by the year 2030.
"Despite the differences in our faith, we all regard addressing the climate emergency as our shared moral challenge. We stand together for our common home, the Earth," the letter says.
"Will you and your Government have the courage to agree to this simple threefold agenda? We pray that you will."
Loreto Sister Libby Rogerson said there is a sacred responsibility to care for the earth and all living beings, especially the "vulnerable people on the frontlines of climate change".
"This is why we feel compelled to publicly urge our leaders, who are failing in their own duty to protect Australia's people and places, to do better," Sister Rogerson said in a statement on Tuesday.
The Grand Mufti of Australia, Ibrahim Abu Mohammed, along with senior Rabbis, bishops and theologians have also signed the letter.
