Comparedto 2006, the decrease was about 25 per cent. This resultwas achieved by such measures as reduced consumption andswitching from fuel oil to biofuels as well as reduction in vehiclefuel use. This reduced consumption may be partly due tothe mild winter. Kalmar and Norrköping no longer remain inLFV’s operations as well. For 2007 calculations, LFV updatedits calculation model and emission factors. 1 As for emissionsfrom district heating systems and electricity consumption atthe Head Office in Norrköping, only carbon dioxide is includedin the results. Emissions from operation and test operation ofreserve power units are not included.The table below reports the number of people exposed toaviation noise exceeding the threshold limit values for indoornoise approved by Parliament. Note that at Göteborg LandvetterAirport, the same individual may be exposed to both typesof noise levels.The number of changed flight paths during the year was27, which meant a saving of about 1,400 kg of carbon dioxideper occasion when using these flight paths. The numberof landings and departures changed during the year was five.For example, to avoid noise over the city of Linköping, holdingposition speed was limited, which means that a smaller area isaffected during landing.During 2007, LFV performed 197 noise insulations in all. Atotal of about 664 properties have been noise insulated, and theinvestment to date has amounted to SEK 82.8 M, with a depreciationperiod of 10 years.0,0030405CO 2kg/passengerNO xg/passengerEmissions from LFV’s operations per passenger.Reducing the effects of run-off waterThe use of glycol as a de-icing agent decreased by 23 per centduring the year.Several airports expanded their inspection programmes forwater testing and reviewed their procedures. Some airportsintroduced new inspection programmes.Malmö Airport completed its construction of equalisationponds, and Stockholm-Arlanda Airport carried out extensiverenovation of its water treatment plant. In test period studies,Göteborg Landvetter presented proposals for run-off watermanagement to reduce the effects on recipients. The GroupAirports Division is carrying out centralised procurement ofrun-off water analyses.Phase-out of chemicals on PRIO listDuring the year, LFV introduced Group-wide procedures forreducing the quantity of chemical products used in its operationsthat are hazardous to the environment or to health. During2007 about 40 product assessments were performed froman environmental and workplace health and safety standpoint.One out of five products approved during 2007 contains substancesfound in the Swedish Chemical Inspectorate’s prioritysettingguide (PRIO). A total of one out of four products usedin LFV’s operations contains substances found on the PRIO list.The chemical information system was supplemented with afunction that updates product information continuously, whichfacilitates the identification of products containing substanceson the PRIO list. A procedure for risk assessment and decisionson phase-out or special protection measures was connected tothis function.060701 Certain emissions were previously calculated locally, while those in 2007 were calculated using a single system.Number of people exposed to different noise levelsAirportNumber exposed tonoise levels exceedingLAeq24h 30db(A),indoorsNumber exposed tonoise levels exceedingLAmax, 3 times/night 45 dB(A),indoorsStockholm-Arlanda Airport 0 1 000Göteborg Landvetter Airport 50 200Malmö Airport 0 50Umeå Airport 0 0Sundsvall Härnösand Airport 0 0Jönköping Airport 0 0Stockholm-Bromma Airport 465 0Total 515 1 250Consumption of anti-skid agents,2003-2007Tonnes3,0002,5002,0001,5001,0005000030405Urea, tonnesAcetate, tonnesFormiate, tonnes0607Performance report > LFV 2007
