Bishop of Salisbury Rt Revd Nicholas Holtam said he had looked at both sides of the debate and would be voting to stay a member of the European Union.
He warned the debate had created a "poisonous political climate".
"I'm very bothered about the way in which we have done damage to the body of politics," he said.
"There's a poisonous political climate with people making ridiculous claims on both sides.
"We need to vote, we need to make the decision and we need to move on."
He's the latest bishop to add his name to a long list of those planning to vote Remain. The Archbishops of Canterbury and York have both signalled their commitment to the EU.
Lord Carey, a former Archbishop of Canterbury, is the most senior clergyman to appeal for a vote to leave.
Detailing why he was voting Remain Bishop Nick said: "It really is important that we remain in Europe.
"That means reforming it but it means remaining, not putting up barriers.
"I feel that particularly as the Church of England's lead bishop on the environment because nature knows no boundaries.
"We need to think about what institutions are going to support us over the next 50 years and the climate is a really big issue that we have to address".
Dr Adrian Hilton from Christians for Britain, which wants to leave the EU, said: "It isn't only' remainers' who care about the environment. Leavers, too, believe that it is God's creation and our common home.
"Leaving the EU would not affect our membership of all the key environmental bodies, such as the Council of Europe, International Maritime Organisation, United Nations or the World Trade Organisation.
"The UK could and would still play a leading role in all of these bodies. It is simply not true to say that we would be "on our own", as the Bishop of Salisbury states.
"Leavers are fully aware that pollution does not stop at national borders.
"It is simply that we believe in inter-governmental cooperation rather than supranational coercion; in a parliament where onerous Green taxes may be repealed and damaging environmental policies reversed, rather than imposed, sustained and policed by unaccountable and immovable authorities."
