Carbon Credits: What Are They? A Simple Definition
A carbon credit is a certificate that shows that one metric ton of carbon dioxide equivalent (CO2e) emissions have been reduced, eliminated, or avoided. Companies or nations can satisfy voluntary sustainability goals or regulatory requirements by trading or selling these credits.
There are two main kinds of carbon credits:
- Used in mandated carbon markets, such as national emissions trading schemes, are regulated (compliance) credits.
- Businesses and people can offset emissions in voluntary climate action initiatives by using voluntary carbon credits.
-
Carbon Markets: Voluntary vs Compliant
Any mechanism that permits the purchase, sale, or exchange of carbon credits is referred to as the “carbon market.”
Market Terms for Compliance:
- Cap and Trade System: A regulatory framework that permits the selling of pollution permits while capping emissions.
- The government-run carbon price marketplace is called the Emission Trading System (ETS).
- Permission to emit a certain quantity of CO2 in compliance markets is known as an allowance.
Terms of the Voluntary Market:
- Offset Projects: Efforts to cut or eliminate emissions in order to produce carbon credits.
- Retirement: When a carbon credit is taken out of circulation permanently in order to claim an offset.
-
Definition of Terms Used in Carbon Trading
- Pricing of Carbon
A system that costs carbon emissions, either through cap-and-trade trading or taxes.
- Trade Caps

- The Carbon Tax
A direct tax on greenhouse gas emissions, which is frequently used in conjunction with or in place of trading schemes.

Market Dynamics and Carbon Credit Pricing
The following factors affect pricing:
- Demand and supply
- Rules and regulations
- Type of project and durability
