Conceptual Framework for Extended Life Cycle Assessment of

debate on appropriate framework, tools and methods to evaluate food and feed along the chains. This paper presents literature review for evaluation of triple bottom line impacts of soy and beef chains in particular, and food chains in general. We reviewed literature on the sustainability of soy and beef chains and concluded that synchronous quantitative assessment of triple bottom line impacts along the soy and beef chains is currently lacking. We proposed to define a framework to bridge the gap between concepts of sustainability and carry out economic, environmental and social evaluation of food business cases especially for soy and beef chains. The framework includes defining relevant triple bottom line indicators, stakeholder preferences and defining quantitative methods for assessment of these impacts simultaneously. However, this paper is still under development and defining framework has been partly done. Moreover, stakeholders’ preferences have not been finished yet.
