This document discusses air emissions and climate change. It defines air emissions as substances in the atmosphere that are harmful to humans and animals. Air pollution is caused by particles and gases from sources like vehicle exhaust, factories, dust, and wildfires. To reduce air emissions, the document recommends using reusable products instead of plastic and electric vehicles instead of gas vehicles. Climate change refers to long term shifts in temperature and weather patterns and is caused by greenhouse gases like carbon dioxide, methane and nitrous oxide emitted from sources such as cars and factories. Solutions proposed to address climate change include renewable energy sources, sustainable transportation, and air pollution prevention.

What is air
emission?
Air emission is the
contamination of
air due to some
substances in the
atmosphere that
are harmful to the
humans and
animals and the

3. Causes
of air
emission
Air pollution is caused by
solid and liquid particles and
certain gases that are
suspended in the air. These
particles and gases can come
from car and truck exhaust,
factories, dust, pollen, mold
spores, volcanoes and
wildfires. The solid and liquid
particles suspended in our air
are called aerosols.

4. How to reduce air
emission?
Replace plastic products into reusable products
which helps stop the emission going to the air
from burning the plastic.
Use solar panel cars instead of fuel which doesn’t
burn fuel which pollutes the air.

5. Climate change
What is climate change? Climate
change refers to long term
shifts in temperature and
weather pattern.

6. Causes of climate
change.
Presentation Title 6
Carbon dioxide
Methane
Nitrous oxide
Sulfur hexaflouride
Perflurocarbom
Hydroflurocarbon
These causes
happen as a
resultant from
petrol cars,
factories etc.

7. Solution of climate
change
Presentation Title 7
• Renewable energies
• Changing our main energy sources to
clean and renewable energy. Solar,
Wind
Sustainable transportation
Our transport methods must be
aligned with environmental
requirements and reduce their
carbon footprint.
Air pollution prevention
Many methods exist to prevent, control
and reduce air pollution, in particular by
reducing the consumption of fossil fuels,
and limiting industry emissions and
