Types of Greenhouse Gases - TSV
Greenhouse gases are the collective term for gases that contribute to rising global temperatures. Carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases (HFCs, PFCs, SF6, etc.) are known as the main types. Each gas is evaluated for its warming impact by the Global Warming Potential (GWP), and they differ in atmospheric lifetime and emission sources. In the International Framework for Climate Change, the IPCC has positioned the reduction of these gas emissions as an important issue.

CO2 carbon-dioxide Carbon Dioxide The most significant greenhouse gas, accounting for approximately 75% of anthropogenic emissions. 数百〜数千年 約75% CO₂ 1 ["Fossil fuel combustion","Cement production","Deforestation"]
CH4 methane Methane Has approximately 28 times the warming potential of CO₂, accounting for about 18% of anthropogenic emissions. 約12年 約18% CH₄ 27.9 ["Agriculture (rice, livestock)","Natural gas extraction","Waste landfills"]
N2O nitrous-oxide Nitrous Oxide Also called laughing gas, with approximately 273 times the warming potential of CO₂. 約109年 約4% N₂O 273 ["Nitrogen fertilizer use","Industrial processes","Fuel combustion"]
HFC hydrofluorocarbons Hydrofluorocarbons Fluorinated gases used in refrigerants with hundreds to thousands of times the warming potential. 数年〜数十年 約1% HFCs 675 ["Refrigerants for refrigerators and AC","Spray cans","Foaming agents"]
PFC perfluorocarbons Perfluorocarbons Used in semiconductor manufacturing, extremely long-lived and potent greenhouse gases. 数千年 0.5%未満 PFCs 6500 ["Semiconductor manufacturing","Aluminum smelting"]
SF6 sulfur-hexafluoride Sulfur Hexafluoride One of the most potent greenhouse gases, with approximately 24,000 times the warming effect of CO₂. 850〜1,280年 0.1%未満 SF₆ 24300 ["High-voltage electrical equipment insulation","Semiconductor manufacturing"]
NF3 nitrogen-trifluoride Nitrogen Trifluoride Used in semiconductor and LCD manufacturing, with approximately 17,000 times the warming potential of CO₂. 長い（数百年以上） 0.1%未満 NF₃ 17200 ["Semiconductor manufacturing","LCD panel manufacturing"]
