Life cycle assessment and carbon foot print

Life cycle assessment and carbon foot print
1) Taking the Life Cycle Assessment perspective, which stage of the life cycle, all the way from raw material extraction to end-of-life disposal, will contribute the highest carbon emissions (kg Co2 eq.) for 1) Biofuel-based cars, 2) Electric Cars, 3) Hybrid Cars and 4) Hydrogen Cars. Consider the system boundary to be well-to-wheel and the functional unit is 1 passenger-km.
Explain your reasoning for each technology pathway separately. (10 points)
2) Each student should keep a diary of all the meals for I day. No need to track individual ingredients, only meals (e.g. omelette for breakfast, chocolate for snack, hamburger with fries for lunch, etc.)
a) Go to the carbon “food”print calculator at: http://www.eatlowcarbon.org/food-scores/ to calculate the total CO2 equivalent consumed per day by summing up the values for all meals. 6 points
If you do not find the exact meal on the website, use a meal from the list with similar ingredients for approximation.
b) What changes can you make in your 1) diet and 2) food source to reduce the carbon footprint? 4 points
