The Green Party has proposed that people using vehicles on London's roads should be charged by journey.
The report suggested that the pay-as-you-go scheme could replace the current congestion charge, raising £1.4 billion every year.
Under the scheme motorists would be charged an average 20p per kilometre for travel across all London boroughs.
The academic report, which will now be sent to Boris Johnson and Transport for London, claims that the move could shave 10% from traffic volumes across the city.
However, there needed to be further discussion on when the charge zones would be operational, the researchers added.
The report's authors said: "Put in very clear language it is our view that a London-wide road pricing scheme is essential and without it congestion will worsen and air pollution will worsen."
