The amount of emissions determined in this work only represents a portion of total emissions during the life cycle of food products (i.e. extraction of raw materials, production, transportation and storage until consumption) [12].
Materials and methods Surveys and audits were performed to agrifood companies located in the central region of Portugal to assess the Portuguese outlook of energy consumption and GHGs emissions in agrifood industry, as well as to define what should be the action points that would foster energy efficiency strategies.
Note that in the horticultural and distribution sectors, the amount of raw materials and final products is the same, because these companies do not have their own production process, working only as warehouses.
