Inimtegevuskasvuhoonegaaside, often translated as anthropogenic greenhouse gases, are gases in Earth's atmosphere whose presence is the result of human activities. These gases trap heat, contributing to the warming of the planet's surface. While some greenhouse gases occur naturally, human actions have significantly increased their concentrations since the Industrial Revolution.

The primary anthropogenic greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases. Carbon dioxide is largely released through the burning of fossil fuels like coal, oil, and natural gas for energy production, transportation, and industrial processes. Deforestation also contributes to CO2 levels, as trees absorb carbon dioxide during photosynthesis. Methane is emitted from sources such as livestock farming, natural gas leaks, and the decomposition of organic waste in landfills. Nitrous oxide is primarily produced through agricultural activities, including the use of fertilizers, as well as from fossil fuel combustion and industrial processes. Fluorinated gases, which include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6), are synthetic gases used in various industrial applications, refrigeration, and aerosols.

The increased concentration of these gases in the atmosphere enhances the natural greenhouse effect, leading to a rise in global average temperatures. This phenomenon is known as global warming and is a major driver of climate change, with consequences such as altered weather patterns, sea-level rise, and impacts on ecosystems. Understanding and mitigating the emissions of anthropogenic greenhouse gases is therefore crucial for addressing climate change.
