f0b7 financial expectations 2013 we are cautious about the economic environment , but , assuming that industrial production grows approximately 3% ( 3 % ) as projected , volume should exceed 2013 levels . even with no volume growth , we expect earnings to exceed 2013 earnings , generated by core pricing gains , on-going network improvements and productivity initiatives . we expect that free cash flow for 2014 will be lower than 2013 as higher cash from operations will be more than offset by additional cash of approximately $ 400 million that will be used to pay income taxes that were previously deferred through bonus depreciation , increased capital spend and higher dividend payments . results of operations operating revenues millions 2013 2012 2011 % (  % ) change 2013 v 2012 % (  % ) change 2012 v 2011 .

Additional report context:
we generate freight revenues by transporting freight or other materials from our six commodity groups . freight revenues vary with volume ( carloads ) and arc . changes in price , traffic mix and fuel surcharges drive arc . we provide some of our customers with contractual incentives for meeting or exceeding specified cumulative volumes or shipping to and from specific locations , which we record as reductions to freight revenues based on the actual or projected future shipments . we recognize freight revenues as shipments move from origin to destination . we allocate freight revenues between reporting periods based on the relative transit time in each reporting period and recognize expenses as we incur them . other revenues include revenues earned by our subsidiaries , revenues from our commuter rail operations , and accessorial revenues , which we earn when customers retain equipment owned or controlled by us or when we perform additional services such as switching or storage . we recognize other revenues as we perform services or meet contractual obligations . freight revenues from five of our six commodity groups increased during 2013 compared to 2012 . revenue from agricultural products was down slightly compared to 2012 . arc increased 5% ( 5 % ) , driven by core pricing gains , shifts in business mix and an automotive logistics management arrangement . volume was essentially flat year over year as growth in automotives , frac sand , crude oil and domestic intermodal offset declines in coal , international intermodal and grain shipments . freight revenues from four of our six commodity groups increased during 2012 compared to 2011 . revenues from coal and agricultural products declined during the year . our franchise diversity allowed us to take advantage of growth from shale-related markets ( crude oil , frac sand and pipe ) and strong automotive manufacturing , which offset volume declines from coal and agricultural products . arc increased 7% ( 7 % ) , driven by core pricing gains and higher fuel cost recoveries . improved fuel recovery provisions and higher fuel prices , including the lag effect of our programs ( surcharges trail fluctuations in fuel price by approximately two months ) , combined to increase revenues from fuel surcharges . our fuel surcharge programs generated freight revenues of $ 2.6 billion , $ 2.6 billion , and $ 2.2 billion in 2013 , 2012 , and 2011 , respectively . fuel surcharge in 2013 was essentially flat versus 2012 as lower fuel price offset improved fuel recovery provisions and the lag effect of our programs ( surcharges trail fluctuations in fuel price by approximately two months ) . rising fuel prices and more shipments subject to fuel surcharges drove the increase from 2011 to 2012 . in 2013 , other revenue increased from 2012 due primarily to miscellaneous contract revenue and higher revenues at our subsidiaries that broker intermodal and automotive services . in 2012 , other revenues increased from 2011 due primarily to higher revenues at our subsidiaries that broker intermodal and automotive services . assessorial revenues also increased in 2012 due to container revenue related to an increase in intermodal shipments. .

Question: what was the percentage change in fuel surcharge revenues from 2012 to 2013?
