Common wheat, a fundamental commodity on international markets, is increasingly differentiated into commercial types on domestic markets to meet the demand of processing companies. Improver wheat, biscuit wheat, ordinary and superior bread-making wheat are commercial varieties with specific technological characteristics. Wheat farming systems are constantly evolving, and as a result, related environmental issues emerge. We applied an LCA (Life Cycle Assessment) analysis, where the functional unit was 1 tonne of grain for each typology and system boundaries were from cradle to farm gate. Primary data were used in the study, and special attention was paid to fertiliser use. From an LCA perspective, our findings show that nitrogen (N) plays an essential role in plant production although producing different waterborne and airborne emissions and nitrate leaching, for the 4 commercial typologies studied. Furthermore, the impact can be differentiated based on the technological features of the commercial types. Our results led us to observe that the four wheat types show contrasting economic and environmental performances.
