Greenhouse gas - Wikipedia
Greenhouse gases (GHGs) are the gases in the atmosphere that raise the surface temperature of planets such as the Earth. What distinguishes them from other gases is that they absorb the wavelengths of radiation that a planet emits, resulting in the greenhouse effect. [1] .
Greenhouse gases - U.S. Energy Information Administration (EIA)
Greenhouse gases absorb this infrared radiation and trap its heat in the atmosphere, creating a greenhouse effect that results in global warming and climate change. Many gases exhibit these greenhouse properties. Some gases occur naturally and are also produced by human activities. Some, such as industrial gases, are exclusively human made.
Required information: Emissions data for all six GHGs covered by the UNFCCC/Kyoto Protocol separately (CO 2, CH 4, N 2 O, HFCs, PFCs and SF 6) in metric tonnes and in tonnes of CO 2 equivalent. Required information: Source of the GWP values and indicate if multiple Assessment Reports have been used. p63; Chapter 9 – Reporting GHG Emissions
What Are Greenhouse Gases and Why Do They Matter
2022年10月12日 · Greenhouse gases (GHGs) are a category of gases that absorb heat energy emitted from the planet's surface and they remain in Earth's atmosphere for a long time (from decades to centuries). Though they make up only a small portion of the atmosphere (less than 1% of all air molecules), GHGs absorb a significant amount of heat energy and re ...
What are the main greenhouse gases? | Explained - NY Engineers
The Kyoto Protocol identifies six main greenhouse gases: Carbon dioxide (CO2) Methane (CH4) Nitrous oxide (N2O) Sulfur hexafluoride (SF6) Hydrofluorocarbons or HFCs; Perfluorocarbons or PFCs; Here we will discuss these six greenhouse gases and their main sources.
Kyoto Protocol - Targets for the first commitment period
The targets for the first commitment period of the Kyoto Protocol cover emissions of the six main greenhouse gases, namely: • Carbon dioxide (CO2); • Methane (CH4); • Nitrous oxide (N2O); • Hydrofluorocarbons (HFCs); • Perfluorocarbons (PFCs); and • Sulphur hexafluoride (SF6)
Greenhouse gases - World Meteorological Organization
2025年1月15日 · Greenhouse gases (GHGs) in the atmosphere trap infrared radiation from the Earth, keeping it warm, this is known as the greenhouse effect. GHG emissions from human activities provided the majority contribution towards global warming of 1.1 °C. Carbon dioxide (CO2) in 2023 was 151% of pre-industrial levels.
