Common mistake:
Learners sometimes confuse 'emission' with 'emissionS'. 'Emission' (singular) is usually the act or process of sending something out, while 'emissions' (plural) often refers to the gases themselves. They may also mix up 'emission' with 'omission', which means leaving something out.
Meaning
act of sending out gas or energy
Collocations
the emission of greenhouse gases
|the emission of radiation
|the emission of light
|emission standards
|emission controls
|emission levels
Synonyms
release (Very general word for letting something go out; does not especially suggest pollution or energy the way 'emission' often does.)
|
discharge (Often used for the flow or sending out of liquids, gases, or electricity; slightly more technical or formal in this context.)
Antonyms
absorption (Focuses on taking in energy or substances rather than sending them out.)
|
capture (Describes actively collecting or trapping gases or energy instead of releasing them.)

Synonyms
