The document discusses various strategies used in cities around the world to reduce air pollution from smog. In Santiago, on high smog days cars without catalytic converters are banned from entering the city. Mexico City hopes to replace petrol and diesel fuels with cleaner natural gas. Los Angeles made cleaner-burning gasoline compulsory in 1996, reducing emissions by 15%. Improving public transportation to provide an alternative to private cars is another strategy discussed. The document also provides additional tips individuals can take to help reduce air pollution and conserve energy.

3. • In Los Angeles:
On bad smog day people
with chest problems, such
as asthma, are warned to
stay indoors.
»Smog: fog or haze
intensified by smoke or
other atmospheric
pollutants

4. • In Santiago:
Strategy #
1
–On days when smog level is high,
cars are banned from entering the
city.
»This apply to those vehicles
without catalytic converters in
their exhausts.
• Catalytic converters remove
many nitrogen oxides, carbon
monoxide and unburnt
hydrocarbons.
• They work most efficiently
when engines are hot.

5. Strategy #
• Replacing petrol and diesel
with cleaner fuels (like gas).
• It is one of the big hopes for
Mexico City.
2
»Helped by the fact that Mexico
has large reserves of natural
gas.
»To date it is mainly used for
vehicles in intensive use, such
as, Public transports.

6. • In LA & California:
–From 1996 the use of CBG
(Cleaner Burning Gasoline)
was made compulsory.
»This fuel reduces ozone-forming
emissions from road
vehicles by 15%.
»This is regarded as the most
important improvement since
the introduction of catalytic
converter.

7. Strategy #
3
• Improving public transport and
making it more attractive
alternative to private car
»Cairo has a brand new, bright,
clean and efficient metro crossing
the city from north to south.
»However metro has specific routes
and roads go everywhere.
»Cars are usually at the top of buying
list in developing countries.

8. • Bike or walk to nearby destinations
• Walk, ride bikes, roller blade, skateboard
instead of driving
• Plant a tree
• Look up air pollution information on the
internet
• Read and learn about air pollution
• Know how air pollution affects your health
• Conserve energy
• Turn the lights out when you leave the room
• Use cold water instead of hot whenever
possible - you'll use less energy
• Use fans to help cool - they use less energy
than coolers and air conditioners
• Reduce, Reuse, then Recycle

9. • Select products with less packaging -
Other
Ways…
packaging consumes energy when it's made,
generates harmful volatile organic
compounds when it's printed, produces
carbon dioxide and carbon monoxide when
it's burned, and generates greenhouse gases
when thrown away in a landfill
• Buy and use products in their non-aerosol
form - propellants used in aerosol cans
contribute to pollution
• When barbecuing, use an electric or
chimney-type charcoal starter instead of
lighter fluid.
• Use a propane grill when barbequing
• Keep your air filter clean and get regular
tune-ups - a neglected car can reduce gas

10. • Keep your air filter clean and get regular
tune-ups - a neglected car can reduce gas
mileage by 20%
• Make sure your tires are properly inflated -
you can save $130 a year in gasoline costs
• Turn the car off while waiting in line at
railroad crossings and drive-thru windows
• Make sure your car's air conditioner is
working properly - leaky air conditioners in
cars are the single greatest source of
chlorofluorocarbons (CFCs), a greenhouse
gas
• Clean the condenser coils on your
refrigerator every few months - you can
reduce electricity consumption 6% or more
• Prevent fires
