Question
The top left corner of Exhibit 1-2 shows inputs for raw materials acquisition. These virgin inputs are used to make various materials, including ore for manufacturing metal products, trees for making paper products, and petroleum or natural gas for producing plastic products. Fuel energy also is used to obtain or extract these material inputs.
Consider the life cycle of the manufactured products as a result of the acquisition of raw materials as illustrated here. Select the one step in this flowchart that not only curtails the release of greenhouse gases but also adds to the overall carbon sink.
