1. Increasing vegetation cover : It will increase utilisation of atmospheric CO2 in photosynthesis.
2. Seeding of oceans with phytoplankton : Increased photosynthetic activity of oceans will result in decreasing CO2 concentration.
3. Carbonation : CO2 released during combustion should not be allowed to pass into atmosphere. Instead, it can be changed into carbonates.
4. Alternate sources of Energy : Instead of fossil fuels, hydrogen fuel and solar energy should be used.
5. Burning of litter : Litter and crop residue should not be burnt but instead converted into manure.
