1 Ιουν 2022 · The table below shows the relative concentrations of these major greenhouse gases and their sources. Some gases (like CO 2 ) are made by both natural and manmade processes, while others (like hydrofluorocarbons) are only the result of human industrial activity.
The major anthropogenic (human origin) sources of greenhouse gases are carbon dioxide (CO 2), nitrous oxide (N 2 O ), methane and three groups of fluorinated gases ( sulfur hexafluoride ( SF 6 ), hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs, sulphur hexafluoride (SF 6 ), and nitrogen trifluoride (NF 3 )).

13 Μαΐ 2019 · Major greenhouse gases and sources. Carbon dioxide (CO 2): Carbon dioxide is the primary greenhouse gas, responsible for about three-quarters of emissions.
15 Νοε 2023 · According to WMO’s Greenhouse Gas Bulletin, released in 2024, atmospheric levels of the three main greenhouse gases - carbon dioxide, methane and nitrous oxide all reached new record highs in 2023.
Total greenhouse gas emissions are the sum of emissions of various gases: carbon dioxide, methane, nitrous oxide, and smaller trace gases such as hydrofluorocarbons (HFCs) and sulfur hexafluoride (SF6). How much does each gas contribute to global greenhouse gas emissions?
25 Σεπ 2024 · Greenhouse gases are gases in Earth’s atmosphere that trap heat. They let sunlight pass through the atmosphere, but they prevent the heat that the sunlight brings from leaving the atmosphere. The main greenhouse gases are: Water vapor; Carbon dioxide; Methane ; Ozone; Nitrous oxide; Chlorofluorocarbons
For climate change, the most important greenhouse gas is carbon dioxide, which is why you hear so many references to “carbon” when people talk about climate change. There are three main reasons CO 2 is so central to the global warming happening today.
