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
