What process primarily produces the greenhouse gases associated with coal energy?

The process that primarily produces the greenhouse gases associated with coal energy is the combustion of coal. When coal is burned to generate energy, it undergoes a chemical reaction that releases carbon dioxide (CO2), a major greenhouse gas. This is a significant concern because CO2 contributes to global warming and climate change when it accumulates in the atmosphere.

During combustion, the carbon stored in coal combines with oxygen from the air, resulting not only in CO2 emissions but also in other pollutants such as sulfur dioxide (SO2) and nitrogen oxides (NOx). The amount of greenhouse gases emitted is directly proportional to the amount of coal that is burned. Consequently, the reliance on coal as an energy source has a substantial impact on greenhouse gas emissions, which is why it is often scrutinized in discussions about renewable energy and climate strategies.

While other options might involve processes that can contribute to emissions in different ways, they are not the primary source of greenhouse gases linked to coal energy. For instance, mining processes can create emissions but are generally less significant compared to those produced during combustion. Likewise, transportation of coal typically contributes to emissions but remains a smaller contributor compared to the combustion itself. Land use changes can have environmental impacts but are unrelated to the specific production of greenhouse
