WebGreenhouse gases are measured in ‘carbon dioxide-equivalents’ (CO 2 e). Today, we collectively emit around 50 billion tonnes of CO 2 e each year. This is more than 40% higher than emissions in 1990, which were around 35 billion tonnes. What are carbon dioxide equivalents (CO2e)? The major constituents of Earth's atmosphere, nitrogen (N 2) (78%), oxygen (O 2) (21%), and argon (Ar) (0.9%), are not greenhouse gases because molecules containing two atoms of the same element such as N 2 and O 2 have no net change in the distribution of their electrical charges when they vibrate, and monatomic gases such as Ar do not have vibrational modes. Hence they are al…
