Table 1, does a leather shoe or plastic shoe result in greater total emissions? State any assumptions you make. (For example: Assume that both shoes have plastic laces – laces excluded from calculation) c) Consider only carbon dioxide emissions (Table 1) and determine which shoe has a smaller carbon footprint: [Ignore chemical productions, paper production and transport] cow leather shoe (0.25 kg) with interlining (0.10 kg), plastic laces (0.010 kg) and rubber sole (0.50 kg) EVA shoe (0.10 kg) without interlining, plastic laces (0.010 kg), rubber sole (0.30 kg)and pig leather tongue (0.15 kg) d) Look up an example of a sustainable shoe manufacturer on the web and describe the materials that are used, the countries from which they are sourced, and any claims about life cycle
