Table 2 shows the impacts for 1 liter gasoline and 1 liter bioethanol over their whole life cycle. Please rank the two options using the hierarchical ranking method based on local and global impacts. You need to show your hierarchical tree and brief justifications for your assigned weighting factors to each category and subcategories. The heating values of gasoline and bioethanol are 34 MJ/liter and 23.5 MJ/liter, respectively. Table 2. Impacts of 1 liter gasoline and 1 liter bioethanol. Impact category 1. carcinogens 2. Non-carcinogens 3. Respiratory inorganics 4. Respiratory organics 5. Aquatic ecotoxicity 6. terrestrial ecotoxicity 7. Terrestrial acid/nutri. 8. Aquatic acidification 9.
