Greenhouse Gases (GHG)

Greenhouse gases (GHG) absorb and emit infrared radiation, helping regulate the planet's temperature. The problem arises when human activities — such as burning fossil fuels or using fertilizers — increase their atmospheric concentration, intensifying the greenhouse effect and causing climate disruptions.

Main GHGs:

• CO₂ (Carbon dioxide): From fossil fuels and deforestation. It’s the most emitted by humans.
• CH₄ (Methane): Very potent. Produced by livestock, agriculture, and fuel extraction.
• N₂O (Nitrous oxide): Linked to fertilizer use and industrial activities.
• Fluorinated gases: Used in refrigeration and industrial processes. Have extremely high warming potential.
• Water vapor: Not directly controlled, but amplifies the effect of other GHGs.

Climate impact: The rise in these gases is behind global temperature increases, melting ice, sea level rise, and extreme weather. The World Meteorological Organization has warned of the risk of entering a climate vicious cycle if urgent action isn’t taken.

Key measures to mitigate GHGs:

• Renewable energy
• Energy efficiency
• Sustainable agriculture
• Reforestation
• Industrial gas regulation
