Research for the charity Tearfund discovered many Christians were changing the way to live to save the planet.
The polling, conducted by ComRes, asked more than 1,500 Christians about their habits and the practical steps they are or would be willing to take to help tackle climate change.
The results showed that 96% of practising Christians in the UK say that they recycle, and 54% say that they walked or cycled where possible instead of driving to help tackle climate change.
Around 37% of those polled said that they currently fly less.
The research has been published as world leaders begin a second week of talks at the COP21 climate conference in Paris, which aims to get a global deal to tackle the crisis.
Paul Cook, Tearfund's Advocacy Director, said: "Christians have led the way in tackling injustice over many years, and are doing their bit on climate change but this poll reveals that there is still more we can do.
"Our lifestyles, in the rich countries, use global resources faster than the environment can cope.
"The damage this causes hits the poorest first and hardest. We must do our part, just as businesses and government are doing their part."
