Carbon emissions is a concept referring to the release of carbon-containing gases, primarily carbon dioxide (CO2) and methane (CH4), into the atmosphere, largely originating from natural and anthropogenic processes. This research field systematically investigates the sources (e.g., fossil fuel combustion, land-use change), sinks (e.g., biological uptake, oceanic absorption), quantification methodologies, historical trajectories, and future scenarios of these emissions. Key characteristics include their role as principal greenhouse gases, their direct contribution to radiative forcing, and their profound influence on global climate change. The significance of studying carbon emissions lies in providing critical data for understanding the Earth's carbon cycle, informing climate mitigation and adaptation strategies, and guiding international environmental policy.
