What Does CO2 Stand For?

CO2 stands for Carbon Dioxide

CO2, or carbon dioxide, is a colorless, odorless gas that occurs naturally in Earth's atmosphere as a trace gas. It is a byproduct of respiration in animals and plants, and the combustion of fossil fuels. CO2 plays a critical role in the Earth's carbon cycle and is a significant greenhouse gas, contributing to climate change and global warming. It is used in various industrial applications, including food and beverage processing, and as a refrigerant. Monitoring CO2 levels is essential for environmental science and climate policy.
