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] .

2022年6月1日 · Carbon dioxide (CO2) is the most abundant greenhouse gas. Each year, hundreds to thousands of times more CO2 is emitted into the atmosphere by human activity than any other greenhouse gas.

GHG（Greenhouse Gas，GHG。）或称温室效应气体 是指大气中那些吸收和重新放出红外辐射的自然和人为的气态成分，包括对太阳短波辐射透明（吸收极少）、对长波辐射有强烈吸收作用的二氧化碳、甲烷、一氧化碳、氟氯烃及臭氧等30余种气体。

2024年11月23日 · 年度溫室氣體指數 (Annual Greenhouse Gas Index，AGGI) 由美國國家海洋暨大氣總署（NOAA） 的大氣科學家定義為"在有足夠的全球測量數據的任何年份，由於長期存在且充分混合的溫室氣體而產生的總直接輻射強迫與1990年基期的比率"。

2025年1月16日 · Gases that trap heat in the atmosphere are called greenhouse gases. This section provides information on emissions and removals of the main greenhouse gases to and from the atmosphere. Click on a greenhouse gas below to …

The main property of greenhouse gases is to absorb radiant energy. The strength of absorption and its atmospheric lifetime will determine the potency of the greenhouse gas. The following list provides some major greenhouse gases – Water Vapour (H 2 O) Carbon dioxide (CO 2) Methane (CH 4) Ozone (O 3) Nitrous Oxide (N 2 O) Chlorofluorocarbon (CFC)

2024年4月1日 · 温室气体核算体系 （Greenhouse Gas Protocol，简称 GHG Protocol ）是一套国际上广泛认可的温室气体会计和报告标准。它由世界资源研究所（World Resources Institute，WRI）和世界商业理事会可持续发展（World Business Council for Sustainable Development，WBCSD）联合开发，旨在为政府 ...

2025年2月26日 · Greenhouse gas, any gas capable of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the phenomenon known as the greenhouse effect. Carbon dioxide, methane, and water vapor are the most important greenhouse gases.

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).

2024年10月28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.
