Greenhouse Gas Emissions (GHGe)
溫室氣體排放

greenhouse effect; greenhouse gas emissions

Greenhouse gases are chemical compounds that contribute to the greenhouse effect. Greenhouse gas allow sunlight (solar radiation) to enter the atmosphere where it warms the Earth’s surface and is reradiated back into the atmosphere as longer-wave energy (heat). Greenhouse gases absorb this heat and ‘trap’ it in the lower atmosphere.

The rapid increase in atmospheric concentrations of the three main human-made greenhouse gases – carbon dioxide, methane, and nitrous oxide – is clear from the data sets for these gases over the last 420,000 years.
