Pollution discharged into the atmosphere from residential chimneys, smokestacks, other vents and surface areas of commercial or industrial facilities and from motor vehicle, locomotive, or aircraft exhausts.

In the context of climate change, emissions refer specifically to greenhouse gases produced and released into the air by numerous activities including burning fossil fuels, industrial agriculture, and melting permafrost. These gases cause heat to be trapped in the atmosphere, slowly increasing the Earth’s temperature over time.
