Which compound can contributes to the greenhouse effect?

Halocarbons are compounds that have significant contributions to the greenhouse effect due to their ability to trap heat in the atmosphere. These synthetic compounds, which include substances like chlorofluorocarbons (CFCs) and hydrofluorocarbons (HFCs), are particularly potent greenhouse gases, often having a global warming potential many times greater than carbon dioxide. They can remain in the atmosphere for an extended period, making their impact on climate change considerable.

Understanding the role of halocarbons highlights the importance of managing and regulating these substances to mitigate their contributions to atmospheric warming. In contrast, while ozone is also a greenhouse gas, its role is more complex as it is beneficial in the stratosphere but a pollutant in the troposphere. Carbon monoxide does not directly contribute to the greenhouse effect but can influence atmospheric chemistry related to gases that do. Nitrogen oxides play a more prominent role in air quality and smog formation rather than being significant greenhouse gases.
