Which greenhouse gas is primarily released from burning fossil fuels?

• A. Methane
• B. Carbon Dioxide
• C. Nitrous Oxide
• D. Ozone

Answer: (B)

The primary greenhouse gas released from burning fossil fuels is carbon dioxide. When fossil fuels such as coal, oil, and natural gas are combusted for energy, carbon contained in these fuels reacts with oxygen in the atmosphere, leading to the formation of carbon dioxide. This process is a significant contributor to the enhanced greenhouse effect, which leads to global warming and climate change.

Carbon dioxide is the most abundant greenhouse gas emitted by human activities, especially in power generation, transportation, and industrial processes. Its long atmospheric lifetime and ability to trap heat make it a major focus of climate change policies and environmental regulations. Understanding this is crucial for those involved in managing and regulating emissions from various sectors, as carbon dioxide emissions are a key factor in environmental sustainability efforts.
