Here's a ranking of greenhouse gases based on their GWP from low to high: 1. Carbon Dioxide (CO₂) - GWP: 1 * Source: Combustion of fossil fuels (coal, oil, natural gas), deforestation, cement production, and land-use changes. * Notes: The baseline GWP of 1, meaning it is the standard against which other gases are compared .....

Methane (CH₄) - GWP: 25 * Source: Agriculture (especially from livestock), landfills, coal mining, oil extraction, and natural gas systems. * Notes: Over a 100-year period, methane is 25 times more effective than CO₂ at trapping heat in the atmosphere. 3. Nitrous Oxide (N₂O) - GWP: 298 * Source: Agriculture (especially synthetic fertilizers), industrial processes, fo .....

Hydrofluorocarbons (HFCs) - GWP: 12 to 14,000 * Source: Used in refrigeration, air conditioning, aerosol propellants, and foam-blowing agents. * Notes: HFCs vary in GWP depending on the specific compound.

Perfluorocarbons (PFCs) - GWP: 7,390 to 17,340 * Source: Produced during aluminum production, refrigeration, and air conditioning. * Notes: PFCs are long-lived and have very high GWPs, with PFC-116 being one of the most potent, having a GWP of 11,500. 6.
