Which type of gas is considered more environmentally valuable in the extraction process?

Natural gas is considered more environmentally valuable in the extraction process due to its lower carbon intensity when burned compared to other fossil fuels. It primarily consists of methane, which produces the least amount of carbon dioxide per unit of energy released. The combustion of natural gas results in fewer pollutants, such as sulfur dioxide and particulate matter, contributing to a cleaner environment.

In contrast, coal gas, derived from coal, releases significantly more greenhouse gases and pollutants during both extraction and combustion. Biogas, while renewable and producing fewer emissions than fossil fuels, relies on organic materials which may not always be as widely available or scalable as natural gas. Propane, although a cleaner-burning fuel than coal or oil, still emits carbon dioxide and other pollutants, making it less environmentally valuable than natural gas. Thus, natural gas stands out for its relatively lower environmental impact during extraction and use, aligning with modern energy transition goals toward cleaner energy sources.
