CO2 levels
Greenhouse gas measurement
CO2 levels refers to the concentration of carbon dioxide in a given environment, typically measured in parts per million (ppm).
The term most often appears in discussions of atmospheric carbon dioxide and climate change: CO2 levels have risen dramatically since the Industrial Revolution.
Indoor CO2 levels indicate air quality and ventilation—high readings suggest a stuffy, poorly ventilated space.
