FOTA revealed that data from 8 teams was analysed by environmental research analysis organisation Trucost.
They found that fuel efficiency led to a 24% cut in carbon emissions from Formula One cars.
There has also been a 14% fall in emissions from electricity use.
Growth also took place, as the increasingly expanding calendar since 2009 means that emissions from business travel and freight rose by 38% and 16% respectively.
"We are delighted to have achieved such significant reductions in our carbon emissions at such an early stage on our journey," said FOTA chairman Martin Whitmarsh.
"With Trucost’s assistance, we have implemented robust systems to manage the carbon emissions of the Teams and identify areas for further emissions reductions. We will continue our focus on fuel efficiency and are also investigating opportunities to shift towards more carbon-efficient freight transport modes. We are delighted that the FIA Institute has launched a global environmental accreditation programme, which underscores the commitment of the sport to taking positive action on sustainability."
