The table and bar chart show information about the modes of transportation used for traveling to work in Houston, Texas, and how much CO2 emissions each type of transport produces.
In the table, it is clear that a private car with only 1 passenger is the most popular transportation; 48% of commuters use it, while only 11 percent of people use a car with more than 1 passenger. Train/bus comes as the second most popular, with 37 percent of travelers preferring this as a main mode of transportation. The least popular is cycling or walking, which is used by only 4%. In terms of average age, people in the age group 43-47 tend to prefer cars or buses/trains when compared to the 39-year-old generation.
Turning to the production of CO₂ emissions, cars with one passenger produce the highest emissions, at more than 0.3 CO₂ emissions per kilogram per person per kilometer, followed by cars with 4 passengers, which produce about 0.1 CO₂. Bus/train and cycling/walking produce the least pollution among these forms of transportation.
In conclusion, cars with one passenger are the most used modes of transportation and also the ones that produce the most CO₂ emissions, while traveling by bus/train and walking/cycling are less chosen, and they also produce small or any CO₂ emissions. Finally, people with an average age above 43 prefer traveling by car, and those 39 years old opt more for vehicles with zero emissions of CO₂.
