Life Cycle Assessment: CO2 to Methane

About this Assignment
For your final report, you will complete the LCA study. All phases of the analysis should be included

Objectives
Reassess goal for an LCA
Reassess the scope of the study
Provide final estimates of material and energy flows for the study
Complete the Life Cycle Inventory Analysis
Provide an interpretation to the LCA results

Directions and Resources
Please refer to Modules 2 and 3 for detailed instructions and resources on how to prepare a complete LCA. In brief, you need to complete:
Phase 1. A goal (note: incorporate instructor feedback from midterm-report and any other changes to the goal of the study)
Phase 1. A scope (note: incorporate instructor feedback from midterm-report and any other changes to the scope of the study)
Phase 2. A Life Cycle Inventory (note: incorporate instructor feedback from midterm-report and any other changes to the LCI)
Phase 3. A Life Cycle Inventory Analysis (this includes selection of indicators, etc.)
Phase 4. An interpretation of the study.
