Most published research concerning the environmental impacts of broiler poultry production is limited to assessments of on-farm gaseous and nutrient emissions. Here, ISO-compliant Life Cycle Assessment was used to predict the broader, macroscale environmental impacts of the material and energy inputs and emissions along the US broiler supply chain. It was found that feed provision accounts for 80% of supply chain energy use, 82% of greenhouse gas emissions. 98% of ozone depleting emissions, 96% of acidifying emissions and 97% of eutrophying emissions associated with the cradle-to-farm gate production of broiler poultry. On-farm inputs and emissions, largely related to heating and ventilation contribute on average only 9% of these impacts. These results underscore the fallacy of landless farming and the importance of full supply-chain environmental management for improving sustainability in the US poultry industry.
