Supply chain disruptions would increase agricultural greenhouse gas emissions

Abstract We investigate the impacts of a global crisis to trade systems such as Russia-Ukraine war on agricultural emissions, using two emissions accounting approaches: (1) production-based approach, which only accounts for domestic and (2) trade-adjustment considers imports exports when calculating emissions. find that can substantially increase in scenario. The relative degree change, however, varies between approaches. At country level, largest increases are found several import-dependent countries. Reasons likely two-fold: high dependence certain countries food from Russia Ukraine, higher emission intensities (i.e., amount per unit product) imported items Ukraine. Very few show lower Our results thus highlight urgent need avoid negative repercussions their while increasing production. Concurrently, our findings underscore benefits an process flows. By reforming adopting approach accounting, contribute towards effective climate mitigation well become more resilient shocks.
