| description | Agricultural greenhouse gas emissions have great impact on climate change and need to be reduced. The production and transport of food accounts for up to 25% of total greenhouse gas emissions. Life cycle assessment (LCA) can be used to measure Global Warming Potential (GWP) between production systems and transports to identify sources of greenhouse gas emissions.
In this study, GWP was measured as carbon dioxide equivalents (CO2eq) and was calculated for Swedish IP-certified apples, Swedish organic certified apples (KRAV), IP-certified apples imported from Italy and IP-certified apples imported from Argentina. The system boundaries were 1) production, 2) sorting, packaging and cold storage, 3) transport to retailer.
Production of Swedish IP apples had lowest emission of CO2eq compared to Swedish organic and Italian IP. Diesel consumption was a major source of CO2eq emissions in the production, independent of production system. Swedish IP-certified apples stored for 3 months had much lower CO2eq emissions than imported apples transported directly at harvest from Italy and Argentina by truck and boat. It is CO2 efficient to increase the market share of Swedish apples if storage time is less than 12 months, as CO2eq emissions are lower than imported apples from Italy and Argentina. |

Produktion och transport av livsmedel står för upp till 25% av de totala utsläppen av växthusgaser. En minskning av utsläppen från jordbruket krävs för att minimera påverkan på klimatförändringen. Livscykelanalys (LCA) är en metod för att jämföra produktionssystem och transporter genom att mäta Global Warming Potential (GWP) i CO2-ekvivalenter (CO2eq). I denna studie beräknades växthusgaser som CO2eq för svenska IP-certifierade äpplen, svenska ekologiska certifierade äpplen (KRAV), IP-certifierade äpplen som importerats från Italien och IP-certifierade äpplen importerade från Argentina. Systemavgränsningen inkluderade, 1) produktionsledet av äpple, 2) sortering, packning och kyllagring (3 månader), 3) transporter från fruktodling till butik (båt, lastbil). Svenska IP producerade äpplen hade lägst utsläpp av CO2eq jämfört med Svenska ekologiska och Italienska IP äpplen. Utsläpp av CO2eq från användning av diesel och elektricitet var en betydande faktor i produktionen av äpple oavsett produktionssystem. Svenska IP-certifierade äpplen som lagrats i 3 månader hade lägre utsläpp CO2eq än importerade äpplen transporterade direkt vid skörd från Italien och Argentina. Det är CO2eq effektivt att öka marknadsandelen för svenska äpplen om lagringstiden är mindre än 12 månader, eftersom CO2eq utsläppen är lägre än för importerade äpplen från Italien och Argentina. 2015-08-19 Second cycle, A1E NonPeerReviewed application/pdf sv https://stud.epsilon.slu.se/8390/17/johansson_d_150922.pdf Johansson, Davida, 2015.
