2.5 Conclusions.

  • LCA is the most common method used for quantifying the environmental impacts and resource use throughout the entire life cycle of a product or service.
  • It comprises four stages: goal and scope definition, allocations of inputs and outputs to stages of the lifecycle, assessment of impacts, and the interpretation of results.
  • LCA of agricultural products is difficult and uncertain.
  • Carbon footprinting is based on the LCA approach but focuses only on greenhouse gas emissions.
  • LCAs have historically focussed on environmental impacts, but are increasingly incorporating societal considerations.
  • LCA is an extremely useful tool but cannot by itself indicate the sustainability of a product or process
