The gas given off when an engine burns fossil fuels during combustion.

The release of a substance (usually a gas when referring to the subject of climate change) into the atmosphere.

The release or discharge of substances, effluents or pollutants into the environment.

Emissions are the products produced other than heat in a combustion reaction.Examples: Carbon dioxide is a common emission from combustion reactions.

The energy transmitted from the source as electromagnetic waves.

Waste fumes or gases from production processes that are released into the atmosphere

 The release of substances (e.g., greenhouse gases) into the atmosphere.

Emissions is a general term for the substances produced when tobacco products are burnt. Emissions may refer to the total amount of smoke generated or to  individual chemicals in smoke (smoke constituents).

Emissions of heat-trapping gases (greenhouse gases), greenhouse-gas precursors, and aerosols associated with human activities. These include the burning of fossil fuels, deforestation, land-use change [..]

Discharge released into the atmosphere from processing.

Materials (gases, particles, vapors, chemical compounds, etc.) that come out of smokestacks, chimneys, and tailpipes.

Quantity of a substance that is thrown to the air.

byproducts of a running engine, including: exhaust pollutants, noise emissions.

Substances that are discharged into the air from industrial processes, vehicles, and living organisms. In the context of global climate change, they consist of important greenhouse gases (e.g., the release of carbon dioxide during fuel combustion).

In transportation, the gases and particles discharged into the atmosphere as byproducts of the combustion process of converting fuel to motive power. These mobile source pollutants are primary contrib [..]

An assessment of how many pollutants a car gives off that is measured by EPA standards. Emissions of common gasses must not exceed the maximum levels set by the EPA.

Something that has been released

Emissions are the byproducts of combustion. After combustion is complete, water, gases, and carbon are released through the car's exhaust system as emissions.

The release of a substance (usually a gas when talked about in the context of climate change) into the atmosphere.

A release of pollutants into the air from a source. Emissions released from any point other than a flue or stack are called fugitive emissions.

The release of gases, liquids and/or solids from any process or industry. Liquid emissions are commonly referred to as effluents.

Term used generically to refer to the various components of the engines exhaust.

In the context of the atmosphere, gases or particles released into the air that can contribute to global warming or poor air quality.

Pollution released or discharged into the air from natural or man-made sources, including vehicles, smokestacks and the spraying of aerosols.

Released or discharged air contaminants in the ambient air from any source.

Particulate escape through or around baghouse into the atmosphere.

The discharge of waste gases into the atmosphere

The release of gases into the atmosphere. Often refers to the emission of greenhouse gases, such as carbon dioxide, during fuel combustion.
