The public will get the chance to vote on plans for a £5 peak hour, weekday charge in December.
Government ministers are offering a £3bn package for new tramlines, extra buses and trains - but only if the region adopts a peak time charge for traffic entering Manchester.
Campaigners today launched their formal efforts to persuade voters to back the move - arguing that the offer was an exceptional opportunity to revolutionise the region's public transport.
The group, which dubs itself the Greater Manchester Yes Coalition, is composed of environment campaigners, business groups and other bodies.
Speaking at the launch in Rochdale, Chris Oglesby, from property group Bruntwood and chair of a pro-charge group of businesses, said the group would spend the next few months "challenging the myths" of the charge.
He said: "The strength of 'The Yes Campaign' is that we are a broad coalition genuinely reflecting the diversity of Greater Manchester. As we have talked to businesses over the summer about the benefits that the investment will bring, we are finding that the tide is turning in favour of the bid."
Postal ballots will be sent out later this year and must be returned by December 11.
Under the proposed Transport Innovation Fund plans, two charge zones would be set up around Manchester.
One would broadly follow the M60 ring road, with traffic charged for crossing the boundary during peak hours, and the other cover the city centre, for which an additional charge would be levied.
Certain vehicles, such as black cabs would be exempt, but some business leaders have expressed fears over the proposed charge, arguing it would hit their profits and put them under increasing pressure to cover their staff's extra travel costs.
A poll earlier this year showed marginal public support for a congestion fee, although the majority of local businesses would oppose it.
Currently, only London operates a congestion charge but the government is keen to expand the scheme. Residents in Edinburgh rejected proposals for charging in 2005.
Speaking at the launch, Pat Connor, from the GMB union's taxi section, said the proposals would relieve congestion and make getting around easier for thousands of people. He said: "Cab drivers have seen traffic get worse and worse in Manchester over the last ten years.
"Obviously we want to see traffic moving if we are going to make the most of our working day. I have no doubt that this £3billion investment is our best chance to tackle Greater Manchester's transport problems."
Ali Abbas, from Manchester's Friends of the Earth group, said: "This is our opportunity to take concrete action to help the environment, rather than just talk."
A spokesman for the Greater Manchester Momentum Group, which is campaigning for a No vote, said: "In the countdown to the referendum, we will campaign vigorously to encourage the people of Greater Manchester to reject transport proposals that will make our city region a uniquely expensive place to live and work, costing us up to £1,200 a year to get to work.
"The current proposals are very badly designed and represent poor value for money.
"We disagree strongly with the suggestion that TIF investment will `revolutionise' our public transport system, when common sense, as well as detailed analysis, shows that introducing the world's largest charging zone - the entire inner M60 area - means public transport will not be a cost-effective, door-to-door alternative to the car for most of us."

Keep it up MEN.
I believe there is a NO campaign, but they don't have the media on their side OR £3m to spend.

THe Governement will get their rake off with VAT
There is public money for transport improvements. It is just a matter of allocating it.
The only backed campaign is for YES. Smoke and Mirrors for those who will end up paying it.
You do not have to own or drive a car to be affected!

All the businesses who are for the con charge are the ones that will benefit the most from it! as their properties will go up in value due to people moving into the city centre to escape the charge! everyoneone else will suffer with increases in the cost of living around manchester.
we are not fooled by this cleverly disguised stealth tax

incidently, a mate of mine had an interview this week. A two year contract running part of the congestion charge. No proviso that a referendum needs to be won first. If they are already tying up contracts, does this suggest the referendum is already a done-deal and will be rigged.

VOTE NO! It is unjust, immoral, will not deliver the benefits promised and cost our children and grandchildren an arm and a leg to pay back - and it will ruin Manchester

Grief Tourist, I sometimes despaire of people that think a few extra buses, new ticketing system and a half hearted tram system is 21st century transport! What do they class as a "world class city"? Do these people ever go to world class cities? This will by no means be in the same league as what I would know as world class, ie New York, Madrid, Sydney, Tokyo. Most world class cities have underground systems that are not affected by surface traffic or weather. If you want to vote YES by all means do so, but dont make claims that can not be qualified. I agree that this would provide improved public transport, but we would be kidding ourselves if we consider it in any way world class.

Plus, bus fares will have to be substantially lower than the cost of the charge or else it wont deter people, and given the cost of getting the bus in nearly £5 for a return already, I cant see it happening.
Dare I say it, ITS JUST A 'VEHICLE' TO SQUEEZE EVEN MORE MONEY OUT OF THE CASH STRAPPED PUBLIC.
VOTE NO!!!
VIVA LA REPUBLIC!

Batfink, remember that the average IQ is 100 so for every person above that (such as myself with an IQ of 155) there is someone somewhere with a score lower than 100.
That accounts for most of those that support this idea - sheeple. The very same sheeple that vote for Labour every election too.
