emits

Emits is the third-person singular form of the verb emit. To emit means to produce and discharge something from a source into the surrounding environment. The term is used across science, engineering, and everyday language to describe the release of energy, matter, or information.

In physics and everyday life, an object can emit light, heat, sound, or radiation; a chemical reaction can emit gas or vapor; a machine can emit electromagnetic signals or noise. The noun form emissions refers to the substances or energy released, with environmental and health contexts focusing on pollutants and greenhouse gases.

In computing, emit is used to describe generating events or signals. Many programming frameworks provide an emit function or method to notify registered listeners that something has happened. For example, an event emitter may emit a data event carrying a payload, triggering handlers elsewhere in the program.

In policy and science, the verb is used to quantify and regulate discharges. A factory or vehicle may emit pollutants or carbon dioxide, and emissions data are used in environmental monitoring and regulatory compliance.
