- Greenhouse gas - Wikipedia
Greenhouse gases trap some of the heat that results when sunlight heats the Earth's surface Three important greenhouse gases are shown symbolically in this image: carbon dioxide, water vapor, and methane Physical drivers of global warming that has happened so far
- What Are Greenhouse Gases and Why Do They Matter
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)
- Homepage | GHG Protocol
Greenhouse Gas Protocol provides standards and tools that help countries and cities track progress toward climate goals In 2023, 97% of disclosing S P 500 companies reported to CDP using GHG Protocol
- Overview of Greenhouse Gases | US EPA
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 learn about its emissions in more detail
- Greenhouse gas | Definition, Emissions, Greenhouse Effect . . .
greenhouse gas, any gas that has the property of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the greenhouse effect Carbon dioxide, methane, and water vapour are the most important greenhouse gases
- Greenhouse Gases - MIT Climate Portal
Greenhouse gases are gases—like carbon dioxide (CO 2), methane, and nitrous oxide—that keep the Earth warmer than it would be without them The reason they warm the Earth has to do with the way energy enters and leaves our atmosphere When energy from the sun first reaches us, it does so mainly as light
- Main Greenhouse Gases - Center for Climate and Energy . . .
Greenhouse gases are molecules in our atmosphere that absorb heat radiating from Earth’s surface, preventing it from being emitted into space
