Carbon dioxide, the most important greenhouse gas, mainly results from the incineration of fossil fuels, coal, petroleum, and natural gas. For simplicity and legibility, the term “CO2” is used synonymously with “CO2 equivalents” throughout the Smart City Wien Framework Strategy. The latter term considers the fact that other gases (nitrous oxide, methane, etc.) also have a greenhouse effect.
