Impact of Combine Harvester Technological Operations on Global Warming Potential

The agricultural machinery is making a considerable negative contribution to the acceleration of global warming. In this study, we analyzed impact combine harvesters (CHs) on warming potential (GWP) by evaluating telematics data from 67 CHs operating in Lithuania and Latvia between 2016 2020. This study examined use their technological operations associated impacts ambient air performed field tests using same CH model determine composition exhaust gases different GWP. confirmed release significant GWP during indirect operation, it was estimated that lengths time were spent idle (~20%) transport (~13%) modes. During these operations, over 13% total (~27.4 t year−1 per CH), affected emissions, released. It calculated reduction exceeding 1 machine can be achieved optimizing idling operations. dual telematics/field test approach facilitates comprehensive assessment both methods for reducing environment.
