Carbon dioxide equivalent of carbon dioxide. Equivalent (e) is the concentration of that would cause the same level of radiative forcing as a given type and concentration of greenhouse gas. Examples of such greenhouse gases are methane, perfluorocarbons, and nitrous oxide. e is expressed as parts per million by volume, ppmv. Carbon dioxide equivalent Carbon dioxide equivalent (CDE) and equivalent carbon dioxide (e and eq) are two related but distinct measures for describing how much global warming a given type and amount of greenhouse gas may cause, using the functionally equivalent amount or concentration of carbon dioxide () as the reference. Carbon dioxide
Sustainable urbanism reduced fuel consumption (limiting nitrous oxide, sulfur dioxide, methane, and other gases that contribute to air pollution). Additionally, reducing the overall aggregate electrical load significantly reduces carbon dioxide emissions. Improve indoor air quality by eliminating unhealthy emissions – such as volatile organic compounds (VOCs) – from building materials, products, and furnishings, and through outside filtering and distribution techniques that control pollutants. Maximize the use of controlled daylighting, which can then be augmented by high quality artificial lighting. Provide good acoustic control. Results in high performance facilities can help address a wide range of human resource concerns by improving the total
