do buses polutes more than cars?

Answer 1

Yes they do because majority of all buses requires diesel.

Answer 2

Besides the greater amount of pollution produced by buses, diesel exhaust worsens asthma and allergy symptoms and increases lung cancer risk. Exhaust exposure is 4 times higher inside a bus vs. car.

However, a bus carries more people at once and unless most citizens are carpooling (which they aren't) it would take many cars emitting lots of polution to carry the same amount of people as the bus.

So it's kind of a stalemate, I guess.

Answer 3

I won't deny the math that some of the other answers made, but they all missed the point. At present time and with all the traffic, a bus system has been converting their rolling stock to environmental friendly fuels. There are buses running on natural gas, hydrogen, bio fuel and even multi-fuels. These cut the estimates of pollution and makes public transportation a more viable method of travel.

Answer 4

If you're comparing one bus to one car, then yes, busses create more polution. But if you're comparing one bus to the number of cars it would take to carry an equal amount of people, the cars cause more polution than that one bus.

Answer 5

If you compare 1 bus to 1 car, then yes. However, you must consider the # of people riding the bus as well. Most of them would be driving their own cars, individually. If you have a bus with 60 people on it, that is anywhere from 15 to 60 cars that aren't being driven (15 if there are 4 people to a car).

Answer 6

Theoretically, yes. However, if you divide the pollution out by person, then no. By this I mean that a car carrying four people pollutes more than a bus carrying 40 (or probably even 15, but I don't know the exact amount of pollution either emits, and it depends on make etc) when you divide the rate of pollution by number of passengers.

Answer 7

A single bus would pollute more than a single car.

But in reality, it would give off less pollution.

How is this so?

Vehicles that run on regular gasoline, which include compact or full-sized passenger cars, trucks, and sport utility vehicles give off 2,421 grams of carbon dioxide per gallon of fuel burned. If the average-sized fuel tank for these vehicles is 12 gallons, that makes 29,052 grams per vehicle, or approximately 64 pounds of CO2.

Mass transit buses run on diesel fuel. Diesel engines give off 2,778 grams of CO2 per gallon. If the average bus has a 200-gallon fuel tank, that's 555,600 grams, or 1,223 pounds.

If you look at it only that way, then yes, buses pollute more than cars.

However, consider the following:

Let's say a mass transit bus driving its usual route in Atlanta carries 40 passengers. Now, if these 40 passengers each drove a separate car, the total amount of CO2 grams would be calculated thus:

2,421 g/gal x 12 gal/car x 40 cars = 2,560 lb. CO2

Now remember, the bus only gives off 1,223 lb. of CO2 for its entire tank. Even with the constant stops. Consider that if 40 more cars were on our highways, we'd see more traffic jams, and those 40 drivers would have to keep starting and stopping, burning off excess fuel. They would have to refuel more frequently than a bus, which might only have to refuel two times a week or so.

So, yes, the bus does give off less.

Answer 8

This is a point I have been trying to get people to understand for a long time ... think about miles per gallon PER SEAT!

A 747 jumbo jet with 550 passengers is getting the same fuel mileage PER SEAT as a 5 passenger car with five passengers in it. The average number of people per car in North America is 1.2 persons per car. So they are burning 4X more per seat than a jumbo jet to drive their cars.

If you look at mileage per seat rather than per vehicle, a commuter train gets 5X better mileage per seat than a car or an airplane.

But if they aren't full, they are wasting energy moving empty seats. An empty bus is no better for the environment than an empty car. In fact, it's much worse.

Answer 9

Yes,
Like people, They more gas they have the more polution it puts out.

Answer 10

yes, but 1 bus can carry like 40 people who otherwise could be driving 40 cars, which polute way more than one bus.
