As agriculture moves toward more sustainable practices, understanding the environmental impacts of agricultural machinery has become increasingly important. This study presents a comprehensive life cycle assessment (LCA) of a tractor, aiming to evaluate its GHG emissions from production to end-of-life of a multi-purpose tractor in Turkey. The functional unit and boundaries are determined first. For the products that are the subject of this LCA study, the functional unit has been chosen as 1 product of final product. All the resulting environmental impacts were analysed as impacts per 1 kg vehicle. Year of these final products produced. The system boundary of this study is from cradle to grave. Tractor lifecycle includes raw material, manufacturing, use and end of life cycle phases mainly. Service life is considered as 10 years. The life cycle assessment (LCA) is performed by combining primary, secondary and LCA software database data according to the standards standards ISO 14040 and ISO 14044. IPCC 2021 method is used. %68 of the emissions originates from Use Phase, %18 from raw material and part production phase, %11 from maintenance, %2 from End-of-life (EOL), %1 from tractor production.

摘要

As agriculture moves toward more sustainable practices, understanding the environmental impacts of agricultural machinery has become increasingly important. This study presents a comprehensive life cycle assessment (LCA) of a tractor, aiming to evaluate its GHG emissions from production to end-of-life of a multi-purpose tractor in Turkey. The functional unit and boundaries are determined first. For the products that are the subject of this LCA study, the functional unit has been chosen as 1 product of final product. All the resulting environmental impacts were analysed as impacts per 1 kg vehicle. Year of these final products produced. The system boundary of this study is from cradle to grave. Tractor lifecycle includes raw material, manufacturing, use and end of life cycle phases mainly. Service life is considered as 10 years. The life cycle assessment (LCA) is performed by combining primary, secondary and LCA software database data according to the standards standards ISO 14040 and ISO 14044. IPCC 2021 method is used. %68 of the emissions originates from Use Phase, %18 from raw material and part production phase, %11 from maintenance, %2 from End-of-life (EOL), %1 from tractor production.
