Its population is about half the size, but each year Melbourne produces 2.5 million tonnes more greenhouse gas emissions than London.
The figures have emerged from a study by Victoria's Bus Association, which looked at greenhouse gas emissions from all forms of transport, including buses, cars, trucks and trains.
Victoria's Bus Association represents 550 private companies that operate more than 4,500 buses and coaches, so it has a vested interest in looking to the future when it comes to reducing greenhouse gas emissions.
The Association's report into the total amount of greenhouse emissions produced by all modes of transport in Melbourne paints a somewhat disturbing picture that will provide plenty of challenges for the State Government in the years ahead.
The research compares the population of greater Melbourne to London.
It reveals that Melburnians use 3.1 tonnes of carbon per person each year, compared with 1.2 tonnes per person in Greater London.
While the report reveals a population using significantly more energy for travel, the report's authors says the figures are easily explained.
Co-author John Stanley is the executive director of Bus Association Victoria.
"London is a much more compact city and if you have a compact city with relatively high density, you can have a dense public transport network, and public transport use is very high in London," he said.
"With a compact city you have shorter trips so those sorts of factors are really fundamental to why the emissions are lower in London."
He says public transport is one part of the answer to solving the emissions problem.
"For example, a substantial improvement in the fuel efficiency of our vehicle fleet is a fundamental requirement if we are going to achieve the sort of cuts that [Professor Ross] Garnaut is talking about," he said.
"I think a lot of the electric technology starting to be looked at now hold out great potential in this regard. I think that probably is going to be the area we are going to see it, but there are some simple things too.
"If you look at car occupancy rates. I mean they average only about 1.4 people per car. If we could increase that by about 10 per cent to say 1.5, 1.6, that is about the same as doubling public transport occupancy."
Professor Graeme Currie is from the Institute of Transport Studies at Monash University in Melbourne.
He says the use of alternative fuels is one of the key ways of reducing emissions, but there are other significant changes required for a city with the geographical spread of Melbourne.
He says urban redesign and infrastructure are central to providing solutions.
"The main constraint we have on getting people to use public transport is the fact that our systems don't cover the whole of the city," he said.
"Infrastructure from my point of view just means we have to provide people with alternatives. At the moment, most people in the city really don't have too much of an alternative other than the car, hence they use it.
"If people can walk to activities, this is a fantastic way of giving them a new alternative. It is good for their health and so forth but unfortunately most people live a long way from any activities of that type."
He says redesign is key to more environmentally friendly transport, but he acknowledges that will take time.
"By redeveloping the city, by having higher density and conglomeration around centres, this could be a way of creating new ways of living," he said.
"Our problem is that it is not going to be something that happens quickly. Getting change like that in our cities will take a while, which is why in some ways the infrastructure step is probably the first one."

At three metres long, 1.6 metres high and 1.5 metres wide, the Nano lives up to its compact name. (Reuters: Tata)
Something akin to a motoring revolution has been unveiled in India - a compact car that will sell for a little over $2,500 when it hits the market later this year.
The makers of the Nano believe it will revolutionise how India's 1.1 billion people get around, but critics say it will be an environmental disaster in a country already plagued by chronic air and noise pollution.
The theme from Stanley Kubrick's 2001: A Space Odyssey played as the Nano was unveiled at the annual Delhi car show by Ratan Tata, the head of India's industrial giant Tata Industries.
"We are very pleased to present these cars to you today," he said.
"They are not concept cars, they are not prototypes. They are the production cars that will roll out of the single plant later this year."
At three metres long, 1.6 metres high and 1.5 metres wide, the Nano lives up to its compact name.
It is a four-door, rear-wheel drive with a two-cylinder gasoline engine that claims to offer 20 kilometres per litre.
But the biggest attraction is not performance, it is price - 100,000 rupees - a little over $2,500 before on-road costs.
The target market is the many million of Indians who currently use a motorbike for family transport.
Still, many months before the car becomes available, potential buyers on the streets of New Delhi seem easily sold on the idea.
"Those people who are riding motorcycles these days can drive a car and they will find it easier to drive a car in the streets," one Indian man said.
"Everyone can afford this car."
The prospect of the Nano's popularity scares environmental campaigners in India, Centre for Science and Environment spokeswoman Anumita Roychowdhury said.
"There is just no room left for more cars in Delhi. If you really look at the city, the roads are already congested," she said.
"Data shows that we have even gone beyond the designed capacity of the roads.
"The traffic speed has come down drastically from 35 to 40kph to 12 to five kph [at] the peak traffic volume.
"Now that clearly brings out the fact that it is a crisis that we need to deal with, because [of] both the congestion and pollution impact.
"This cheap motorisation that is now going to explode in Indian cities, we are not prepared for it at all."
The Nano is the brainchild of Mr Tata, the 70-year-old head of the family company. And the old man bristles at criticism the car may not be eco-friendly.
"We may as well come to grips with the fact that all the things that you ask for may not be in a one-lakh (100,000 rupees) car and all the things that might be there in an eco car, may not be possible for one lakh," he said.
"Take it as it is. It's a car that's affordable, provides transport, meets all safety laws, meets all emission laws present and future.
"[It] will be a reliable form of transport which will provide Indian families an all-weather means of safe transport."
But it is not just the Nano for India. In two or three years' time, Mr Tata wants to roll out export version of the Nano to developing countries around the world.
I read it accidentally on ABC news and I took it complete in our blog, because I don't know how long will it be readable (we have some links, which doesn't more working because the report was deleted).
Anyway, the link is http://www.abc.net.au/news/stories/2008/01/17/2140973.htm and if it doesn't work the report is below.

A stay in India's capital often leads to a case of the notorious "Delhi belly", but as pollution rises, many visitors and residents are suffering from the Delhi itchy eye and hacking cough too.
Authorities blame the rise in pollution squarely on a jump in diesel cars, the fumes of which are routinely cited in medical studies as a major health risk.
About a third of the nearly 1,000 new cars that hit the city's roads every day are diesel models, which are becoming popular because the fuel is cheaper than petrol.
But while there is a financial saving, experts warn that it comes at a serious pollution and health cost.
They say New Delhi is rapidly losing the air quality gains made after switching its diesel bus fleet to compressed natural gas six years ago.
Pollution figures show a steady rise in diesel-linked pollution during the past five years, a period that saw the total number of cars in Delhi leap 50 per cent to 1.6 million.
Anumita Roychoudhury from New Delhi's Centre for Science and Environment notes that carbon monoxide levels are falling despite an increase in the number of petrol cars.
However, "for diesel cars, the increase in vehicle numbers and increase in nitrogen dioxide are strongly correlated," she said.
She points to "horrendously" high levels of lung-irritating soot linked to exhaust-pipe diesel emissions, which environmentalists regard as one of the most toxic forms of air pollution.
Ms Roychoudhury has urged India to adopt ultra-clean car standards cutting diesel sulphur levels.
"You need a technology leapfrog," she said.
The planned launch of the world's smallest car, the Nano, by India's Tata Motors has further heightened concerns about increased congestion in the city even though it is only producing a petrol version.
The makers of the car, meant to retail for 100,000 rupees ($2,900), insist its emissions are as low or lower than any two-wheeler on Indian roads and meet European standards.
Sunita Narain, who directs the Centre for Science and Environment, says that's only half the point.
"I am not fighting the small car," she said.
"I am simply asking for many more buses and bus lanes - a complete change in mobility."
Ms Narain was behind the push for the Supreme Court to order the New Delhi bus system to shift to natural gas.
"The solution is not to ban the 100,000 rupee car, [but] tax it like crazy until it [India] has a proper mass transit system," she said.
Doctors say they too have seen the worrying effects of the rise in diesel car numbers.
Randeep Guleria, a chest specialist at the All-India Institute of Medical Sciences, the country's largest public hospital, said the high pollution level triggered asthma in people where the condition previously had been latent.
"We are seeing a lot of such patients, who did not have any problems when they were outside and when they move to Delhi they suddenly develop symptoms," he said.
One of Dr Guleria's patients, 59-year-old Madhu Puri, says her asthma symptoms improve during the six months she spends with a son in New Jersey in the United States. But it is a different story when she comes back to the Indian capital.
"It has been really bad since I came back in November. I cough all night," she said.
"If I go to America or a foreign city I feel better."
A panel of US Environmental Protection Agency has described diesel fuel exhaust as a "likely human carcinogen," linking it with lung cancer and asthma attacks.
Some studies show children are among the worst-affected by the dense haze that often shrouds the city, and doctors frequently tell parents to keep their children indoors when smog levels are particularly high.
Researchers believe particulates, or tiny particles of soot, interfere with the respiratory system because they are so small they can be breathed deeply into the lungs.
In a survey of almost 12,000 city schoolchildren late last year, 17 per cent reported coughing, wheezing or breathlessness, compared to just 8 per cent of children in a rural area.
Twisha Lahiri from India's Chittaranjan National Cancer Institute led the study.
What researchers saw were the effects of "chronic exposure from living in Delhi," she said.
