emission
An emission is the act of sending out or releasing something like gas, light, or heat into the air.
Explanation at your level:
An emission is when a car or a factory sends smoke into the air. It is not good for the earth. We want to have fewer emissions to keep the air clean for you and me.
When a machine like a car runs, it releases gas. This release is called an emission. Many cities want electric cars because they have zero emissions. This helps the environment stay healthy.
Emission is a noun used to describe the release of gases or radiation. You will often hear about 'carbon emissions' in the news. These are the gases that cause global warming. Governments are trying to lower these emissions to protect the planet.
The term emission is frequently used in environmental science to discuss pollutants. It refers to the discharge of substances into the atmosphere. Because of climate change, the reduction of emissions has become a major political and economic goal for countries worldwide.
In academic and formal discourse, emission denotes the systematic release of matter or energy. Beyond environmental contexts, it can describe the radiation of light or heat from a source. Understanding the nuance between 'direct emissions' and 'indirect emissions' is crucial for those studying sustainability and corporate environmental responsibility.
Etymologically derived from the Latin emittere, emission encompasses a broad spectrum of 'sending forth.' While modern usage is dominated by the environmental crisis, the word retains its historical roots in physics, describing the spontaneous release of particles or waves. Its usage reflects the tension between industrial progress and ecological preservation, serving as a key signifier in the Anthropocene era.

- Emission means the release of gas, light, or heat.
- It is a key word in climate science.
- It comes from the Latin word for 'to send out'.
- Commonly used with 'carbon' and 'zero'.
Think of emission as the act of 'letting something out.' When you breathe, you are technically performing an emission of carbon dioxide! However, in the modern world, we usually use this word to talk about pollution.
When we discuss greenhouse gas emissions, we are talking about the gases released by cars, power plants, and factories. These gases float up into the atmosphere and change our climate. It is a very important word for understanding how humans impact the planet.
Essentially, any time a source releases energy or matter into the environment, we call it an emission. It could be light from a star, radiation from a medical device, or exhaust from your neighbor's old truck.
The word emission comes from the Latin word emittere, which literally means 'to send out' or 'to let go.' It is a combination of ex- (out) and mittere (to send).
This root word is quite busy in English! You can see it in words like transmit (send across), admit (send in), and remit (send back). The word emission entered English in the 17th century, originally used in scientific contexts to describe rays of light or heat being 'sent out' from a source.
It wasn't until the industrial age that the word became synonymous with pollution. As factories began pumping smoke into the sky, people needed a word for that discharge, and emission fit perfectly. It has evolved from a general scientific term to a central word in global environmental policy.
While emission is a technical word, it appears in several fixed expressions:
- Net-zero emissions: A goal where the amount of gas added to the atmosphere is balanced by the amount removed.
- Emission standards: The legal limits set by governments on how much pollution a vehicle can release.
- Zero-emission: A term used for electric cars that produce no exhaust.
- Fugitive emissions: Unintentional leaks of gas from equipment.
- Carbon footprint: While not containing the word 'emission,' it is the most common idiom used to describe the total emissions caused by an individual or company.
Emission is a countable noun, so you can have one emission or many emissions. It is usually preceded by an article (the, an) or a possessive pronoun.
Pronunciation: In the UK and US, it is pronounced ee-MISH-un. The stress is on the second syllable. Rhyming words include transmission, permission, omission, and commission.
It is often used as a modifier in compound nouns, such as emission levels or emission control. When you are writing, make sure to check if you are talking about a single event (singular) or the total output (plural).
