Green technological interventions for controlling carbon footprint in agro-food processing: a critical review

The major cause of climate change has been attributed to the food systems. Thus, sustainability in the agri-food processing industry is becoming increasingly crucial in terms of carbon footprint estimation. The unit operations in the food supply chain, such as processing, packaging, transportation, and consumption, emit various greenhouse gases, which increase the footprint during the food supply chain. Hence, the review article highlighted green technological interventions in the food supply chain with case studies of pre-harvesting and post-harvesting operations. Additional information about carbon footprint (CFP) labeling, packaging, storage, and transportation is discussed to minimize greenhouse gas emissions (GHGE) and enhance consumer awareness in terms of food choices based on the carbon footprint values of the product. Green technologies subject to the food supply chain positively influence sustainability. This technology will aid in the strategic decision-making process for reducing food waste and reducing carbon footprint production.
