Car pollution facts - Typical amounts of fuel burned
- Americans use nearly 400 million gallons of gasoline every
day (not all in cars)
- California alone uses over 40 million gallons per day, about
equal to China...China is quickly catching up
- 400 million gallons will fill a 600 acre lake about 2 feet deep

There have been many car pollution facts recorded in the last 100 years. The history of car pollution has been one of air and water contamination followed by regulated improvement. Cars may be fun, useful, and profitable, but except for shiny exteriors and new smelling interiors, they are not clean. Cars have long put millions of tons of dirt and bad chemicals into the air and water. This trend had been led by consumer demand followed by profiting manufacturers, oil companies, and government inaction.
Car pollution facts - General
- Cars pollute the air, water and land.
- Cars today are in fact much cleaner than 30 years ago.
But, there are many more cars driving many more miles.
- Cars and trucks cause a lot of air the pollution in the world
today, and contribute a lot to the most common and
dangerous air pollutants.
- China and the USA alone produce close to half of the
world's carbon dioxide...much of that from cars.
- SUVs pollute a lot more than cars.
- Most ozone pollution is caused by cars and trucks.
- Your car makes carbon dioxide based only on how many
gallons of gasoline your car burns.
- It's not the kind of car you drive, but how many miles you
drive it and how many gallons of gas you burn that counts.
- Car tires wear out as you drive on them and the particles
from those tires go into the air.
- The air near within a few hundred yards or so of big streets
is most likely polluted with harmful particulates from, and
stirred up by, traffic.
- Car washes make our cars shine, but put pollutants into
streams, waterways, and eventually drinking water.
- The National Geographic reports more tornadoes in the USA during the week than on the weekend. Weekday commuter pollutants are to blame!
Car pollution facts - Amounts of air pollution
- According to the National Geographic, over half the air pollution in the USA is
caused by transport, mostly automobiles.
-1,400 new vehicles arrive in New Delhi, India daily adding to 7 million already there, a
65 percent increase since 2003. Resulting fine particle pollution has gone up around
47 percent and NOx rose 57 percent as well - from the New Delhi Journal. - 70% of air pollution in Chinese cities is from cars and trucks.
- 42% of air pollution in Dubai is from cars and trucks.
- 17% of air pollution in Hong Kong is caused by the 550,000 gas burning cars there.

- Human activities release over 130 times the amount of CO2 emitted by volcanoes.
- About 5-7% of the particles from worn out tires heads into the air as PM10
or less sizes. These PM sizes are bad for the lungs.
- 2010 cars are about 20 times cleaner than cars 20 years ago.
- CO (carbon monoxide) emissions have decreased a significant amount.
- HC (hydrocarbon) emissions have decreased a significant amount.
- PM 2.5 emissions have been lowered with cleaner fuels.
- PM 10 emissions will only improve with less vehicular travel.
- It is estimated that of the CO2 emissions produced over a car's lifespan, 10% come
from its manufacture and 5% from its disposal, with the remaining 85% coming from
fuel use and servicing operations.
- Sleeper cab diesel rigs idle 28 hours per week, burning 1500 gallons of fuel per
year per rig.
- Traffic congestion wastes billions of gallons of gas.
Car pollution facts - Health effects
- Moms in highly car polluted areas have smaller babies which is not good for their
health. This is according to The Journal of Environmental Health Perspectives.
- The Stanford School of Medicine says Moms living in the San Joaquin Valley of
California during their early weeks of pregnancy had an elevated risk of having birth
defects in their newborns due to air pollution.
- China has its share of newborns with birth defects. In the highly polluted Shanxi
province, 140 babies out of 10,000 born have had congenital neural tube defects.
The findings are in the Aug 2, 2011 Proceedings of the National Academy of

births in China were the result of bad air.
- India experienced 620,000 preemies in the same time.
- According Government of Scotland data, up to 3,000 people die there from car
induced air pollution. This is in contrast to 190 killed per year in car crashes.
- About 80 people per DAY are killed in the USA from car induced air pollution...or
- Air Particulate Matter pollution kills an average of 40,000 per year in the U.S. and
up to some 200,000 in Europe.
