Goal and Scope: Practice

We will do a bicycle Life Cycle Assessment. The goal of the bicycle life cycle assessment is to evaluate the global warming impact of bicycle materials and bicycle use over $10$ years. Now, it is time to identify the scope of this LCA. Complete the tasks below step by step.

$1.$ Draw a system diagram of a bicycle $(20).$

$2.$ Define a functional unit for a bicycle LCA $(10).$

$3.$ Identify reference flows for a bicycle LCA $(20).$

Hint: The reference flow is a quantified amount of the product$($s$),$ including product parts, necessary for a specific product system to deliver the performance described by the functional unit.

$4.$ Define the system boundary for your bicycle LCA $(10).$

$5.$ Draw the life cycle of a bicycle $(20).$

$6.$ What are your cut$-$off criteria? $(10)?($e$.$g$.,$ mass under $5$ g was not considered$)$

$7.$ Reference $(10)$
