For the father-of-three has just returned from a 1,000 mile walk from Belfast to London in support of Christian Aid's Cut the Carbon march.
And at a special Harvest Thanksgiving service at the Church of the Holy Spirit in Mossley, the 57-year-old told his congregation that everyone needs to play their part in saving the planet before it is too late.
This was no ordinary service. Rotten fruit and vegetables, dead plants, rocks, stones, sand and United Nations relief boxes were among the items displayed to highlight the effect climate change is having in the Third World.
He told parishioners their "alternative harvest" was a way of saying "in creation there's enough to go round but we are not sharing".
Neil began his 82-day trek, in mid-July along with 18 other volunteers from the UK. He completed the gruelling walk on October 2 with a service in St Paul's Cathedral in London.
"I walked every inch of it. At times it was good fun, it was always interesting and always rewarding and worthwhile," he said.
"We feel the effects of climate change a bit in Northern Ireland but it is making huge differences in the developing world - such as unseasonable floods, an unseasonable drought," he said.
"It's about the patterns being completely disrupted. But unfortunately in the developing world they haven't got the resources to fall back on and have to rely on handouts.
"But they want to stand on their own feet and not have food handed out to them. They are proud people."
Mr Cutcliffe urged local people to back Christian Aid's Cut the Carbon campaign.
"A vast amount of the carbons creating the problem didn't come from places like Africa, they came from places like Europe and the United States," he said.
"India and China have been labelled as the biggest threats but we still need to do something because we all live on the same planet. We're not going to have a planet left if we don't do something."
"What we are wanting people to do is think seriously about the waste and to lobby MPs and MLAs about this," he said.
"Thinking about simple things like car journeys or the ways in which we use electricity helps the cause.
"People don't like to be taken out of their comfort zone - but it's all part of changing our mindsets as soon as possible because we don't have 50 years to wait."
