Carbon dioxide emissions associated with a onenight stay in a hotel room are calculated at 29.53 kg of CO2 per room day for an average hotel. The 200 rooms of your hotel are all occupied for two days during a college football game.
a. How much CO2 did the guests and hotel release into the atmosphere?
b. What work, leisure activities, and processes in the hotel generate CO2 emissions? Provide three examples and explain how carbon dioxide is emitted.

A Jet Air 304 airplane emits 22 kilograms of carbon dioxide per hour while flying. Today, the plane flew for 8.2 hours on six flights. This emission rate doesn’t include the time on the ground running its engines and other airport gate and airport emissions.
a. How much carbon dioxide did the JetAir 304 airplane release into the atmosphere today?
b. What work, leisure activities, and processes in the airline and airport generate CO2 emissions? Provide three examples and explain how carbon dioxide is emitted.

Assume you are the chief operating officer of the fast food chain with 5,500 stores in North America. Each store operates 360 days a year and has one heated dryer in the ladies and men’s restrooms. Each dryer operates 200 times per day per restroom. One pound is 453.6 grams. To dry your hands in a retail store restroom requires zero carbon dioxide emissions if you let your hands drip dry. If you use one standard size paper towel, 10 grams of CO2 were generated to manufacturer the towel. If you use a standard heated electric dryer 20 grams of CO2 are used to generate this energy and operate the dryer.
a. How many pounds of carbon dioxide are released in the atmosphere from the heated electric hand dryers in the fast-food chain’s stores?
