What are the main GHG?

Greenhouse gases are naturally occurring or man-made gases in the atmosphere that absorb and re-emit solar radiation, causing the planet to warm.

Several regulations address greenhouse gas emissions, but the Kyoto Protocol is a key one.

• The Kyoto Protocol, adopted in 1997 and enforced in 2005, is an international treaty linked to the United Nations Framework Convention on Climate Change (UNFCCC). It specifically targeted industrialized nations, setting binding emission reduction targets for a group of these countries.

• The Kyoto Protocol identified six main greenhouse gases for these reduction targets:

  • Carbon Dioxide (CO2)

  • Methane (CH4)

  • Nitrous Oxide (N2O)

  • Hydrofluorocarbons (HFCs)

  • Perfluorocarbons (PFCs)

  • Sulfur Hexafluoride (SF6)

It's important to note that while the Kyoto Protocol focused on these six gases, the UNFCCC itself acknowledges a broader range of greenhouse gases that contribute to climate change.
