CO₂ stands for carbon dioxide, a colorless and odorless gas composed of one carbon atom and two oxygen atoms. It is a naturally occurring compound found in low concentrations in the Earth’s atmosphere. CO₂ is produced, among other things, by the respiration of living organisms, the combustion of fossil fuels such as coal, oil, and natural gas, and is also released during the decomposition of organic material. Plants absorb CO₂ during photosynthesis and convert it into oxygen and glucose, making it an essential component of the global carbon cycle.
CO₂ (carbon dioxide) is a significant greenhouse gas that contributes to global warming. Greenhouse gases, such as CO₂, methane, and nitrous oxide, have the ability to trap heat in the Earth’s atmosphere by absorbing and re-emitting infrared radiation. This leads to a temperature increase in the atmosphere, known as the greenhouse effect, which drives significant climatic changes and global warming. According to the Intergovernmental Panel on Climate Change (IPCC), the increase of CO₂ in the atmosphere since the industrial revolution is a major driver of climate change.
The concentration of CO₂ (carbon dioxide) in the atmosphere is measured in “parts per million” (ppm) and is currently around 419 ppm, showing a significant increase compared to pre-industrial levels of about 280 ppm. The main sources of this increase are industrial processes, transportation, and agriculture, which release large amounts of CO₂.
In industrial use, CO₂ is used for carbonation of beverages (e.g., in carbonated drinks) and as a refrigerant. It is also used in medicine, such as for minimally invasive surgeries.
