Biodiesel (density 0.88 kg/L) from soy oil has life cycle emissions of about 1150 gCO2eq/L. Diesel (density 0.80 kg/L) has life cycle emissions of about 2600 gCO2eq/L. Coffee has life cycle emissions of about 17,000 gCO2eq per kg, and beef has life cycle emissions of about 60,000 gco2eq/kg. Annual worldwide consumption: Coffee: 10 billion kg Beef: 59 billion kg Diesel: 1.5 trillion liters Biodiesel: 40 billion liters i) What leads to more global emissions - beef consumption or use of diesel fuel? ii) What leads to a greater emissions reduction - reducing coffee consumption by 10% or displacing 1% of diesel consumption with biodiesel? Comment on your results from (i) and (ii), and what this implies in terms of global efforts and policies to reduce GHG emissions
