The Tour of Britian visits Norfolk for the first time in September 2010
Scientists from the University of East Anglia (UEA) are set to calculate the carbon footprint of The Tour of Britain as it passes through Norfolk.
The Carbon Reduction (CRed) Programme will examine the energy used to host the tour, including spectator travel.
CRed will then propose ways for the event to be as environmentally friendly as possible in the future.
The Tour of Britain visits Norfolk for the first time on Thursday, 16 September 2010.
Race organisers and counties planning to host a stage of the race in 2011 will be able to access the plan to find ways of cutting emissions, while ensuring the spectacle is not damaged for the fans.
The chief technical officer of CRed, Dr Simon Gerrard, said: "Engaging fans and the local community in carbon reduction could help offset the emissions of the tour and stimulate the kinds of behavioural changes needed to avoid the worst consequences of climate change.
"These changes can also improve peoples' health and save them money," he added.
The Tour of Britain is one of the UK's biggest live sporting events attracting more than one million spectators to the roadside in 2008, and the fans' travel choices are likely to have a large affect on carbon emissions.
For many sporting and festival events, spectator travel can account for 60 to 70% of the overall emissions.
Derrick Murphy, Norfolk County Council's cabinet member for Cultural Services, said: "Our county is renowned for its pioneering environmental and science businesses.
"It is really pleasing to see a local organisation, who are the leading lights in their sector, doing work within their own county which will also benefit the whole of Great Britain.
"Cycling is a very environmentally-aware sport and I know CRed's work on this project is really welcomed."
CRed has previously examined the carbon output of the FA Cup, Ipswich Town FC, the Electricity Supply Board of Ireland and the Gaelic Athletics Association at Croke Park in Dublin.
