Green House Gases (GHG)

Green house gases or a combination of various toxic chemicals released into the atmosphere.

The core greenhouse gases are:

• carbon dioxide (CO2),
• methane (CH4),
• nitrous oxide (N2O),
• and fluorinated gases (F-gases).

Together, these gases make up about 98 percent of all greenhouse gas emissions:

1. Carbon dioxide is the most significant, accounting for about 82 percent.
2. Methane accounts for about 11 percent, but can cause most harm,
3. Nitrous oxide and F-gases account for 5 and 2 percent.
