1. Lab 5, Part 3: Your Own CO2 Emissions

3. We know: 0.5 kg CO2/kWh
So that means 0.5 kg of CO2 emitted per 1 kWh of electricity used
Therefore…
For 1000 kWh we emit 500 kg of CO2!
(1000 kWh used)*(0.5kg/kWh)=500 kg

5. Example: My grandma lives in Riverhead, Long Island
Example: My grandma lives in Riverhead, Long Island. It is 150 miles round trip for me to go there. If I go once a month  150miles*12trips=1800miles
Usually 2
Subaru Forester  24 city/ 32 highway
Total Miles: 1800
Miles for me only: 1800 miles/ 2 people = 900 miles
Fuel consumption: 900 miles/ 32 mpg = gallons of fuel per year

7. Fuel consumption (see #4): 28.125 gallons of fuel per year
CO2 emissions = (9kg/gallon)*( gallons) = 253 kg CO2 per year due to fuel consumption
Distance: 5.5 miles (one way)  11 miles round trip
Commute: (11 miles)*(5 days a week) * (52 weeks in a year) = 2860 miles per year commuting to CCNY
Emissions = (2860 miles) * (0.073 kg CO2/person/mile) = kg CO2
New York  Los Angeles is ~2,800 miles
Round trip (x2) = 5600 miles
Emissions = (5600 miles) * (0.42 kg/person/mile) = 2,353 kg CO2

8. 500 kg CO2
Air travel + public transportation + personal car travel =
2,353 kg CO kg CO kg CO2 = 2814 kg CO2
Home + Transportation =
= 3314 kg CO2

10. My total emissions: 3125 kg CO2
