Sulphur Emission Control Area traces of heavy metals, refined petroleum products containing halogen compounds, sewage sludge and sludge oil. The Marine Environment Protection Committee (MEPC) has strongly encouraged members to use the scheme to report the greenhouse gasses emissions. Those gasses include Carbon dioxide, Methane, Nitrous oxide, Hydrofluorocarbons, Perfluocarbons, and Sulfur hexafluoride. The purpose of making the guidelines on CO2 emissions is to develop a system that would be used by ships during a trial period. In 2013 new regulations described in a chapter added to the MARPOL Annex VI came into effect in order to improve "energy efficiency of international shipping. The regulations
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
