What is a life cycle analysis?
• LCA is a technique to assess the environmental aspects and potential impacts associated with a product, process, or service, by:– compiling an inventory of relevant energy and
material inputs and environmental releases;– evaluating the potential environmental impacts
associated with identified inputs and releases;– interpreting the results to help you make a more
informed decision.
Steps
• 1) Raw Materials• 2) Extraction• 3) Processes• 4) Transportation• 5) Product
What are Raw materials?
What is Extraction? • Manual long harvesting/whole tree harvesting• Mechanical whole tree harvesting/log length
What are processes?

What is transportation?
What is a product (use)?
What are inputs and outputs?
• Inputs = materials and energy used • Outputs = waste and pollution created
