Answer 1

The Correct answer is Carbon tetrachloride.

Key Points

Carbon tetrachloride is not considered a greenhouse gas.
Greenhouse gases are those that absorb and emit radiant energy within the thermal infrared range, leading to the greenhouse effect.
Carbon tetrachloride is a chemical compound with the formula CCl₄ and is used mainly in fire extinguishers and as a cleaning agent.
Although it has some environmental impacts, it does not significantly contribute to the greenhouse effect.

Additional Information

Methane
- Methane (CH₄) is a potent greenhouse gas, with a global warming potential much higher than carbon dioxide.
- It is produced through natural processes and human activities like agriculture, particularly from the digestive systems of grazing animals.
Nitrous oxide
- Nitrous oxide (N₂O) is a greenhouse gas emitted from agricultural and industrial activities, as well as during the combustion of fossil fuels and solid waste.
- It has a global warming potential of 298 times that of carbon dioxide over a 100-year period.
Carbon dioxide
- Carbon dioxide (CO₂) is the primary greenhouse gas emitted through human activities, especially from burning fossil fuels.
- It is a major contributor to the greenhouse effect and is responsible for about 64% of man-made global warming.
