atio = c) calculate the absolute (in tons) and relative increase in co2 emissions (%) during period 1997-2008. 1997: co2(1) = 2008: co2(2) = absolute increase = relative increase= *100% * ∆ car emissions (exhaust gases) carbon dioxide is the main greenhouse gas. ghgases are measured in co2 equiv. units gasoline used as fuel in cars when burning produces co2 that contributes to gh effect cec (car emission coefficient) shows how much emissions are released into the atmosphere by 1l gasoline. for average passenger car cec ~ 2.42 kg co2 /l * fuel efficiency & fuel consumption fuel efficiency rate – distance traveled per unit of fuel used (km /l): fer = d/v example: 10 km/l means that 1 l gasoline is required to drive 10 km. fuel consumption rate shows the amount of fuel used per certain distance (l/100 km) example: 7 l/100 km means that 7l of gasoline …

suming that your car’s monthly mileage is 900 km and its fuel efficiency is 15 km/l, calculate your annual car emissions in kg of co2. given: mm=900 km; fer=15 km/l; cec = 2.42 kg co2/l solution: let’s find first monthly emissions: monthly car emissions = cec x monthly fuel consumption to find monthly fc, use proportion: 15 km – distance traveled per 1l gasoline 900 km ----------------------------- xl gasoline - monthly fuel consumption * * practice problem #2- solution monthly car emissions = 2.42 kg co2/l x 60l = 145.2 kgco2 to find annual car emissions, multiply monthly value by 12 (months): 145.2 kg co2 x 12 = 1742.4 kg co2 * * air pollution control maximum admissible concentration, mac of pollutant is a standard level of pollutant (air, water or soil) below which there is virtually no harm to human health or the environment. magnification ratio, mr – ratio …
