CO2 emissions refer to the emission of carbon dioxide, a greenhouse gas, into the atmosphere. Carbon dioxide consists of carbon and oxygen and has a decisive influence on our climate. CO2 emissions result, for example, from the combustion of carbon-containing materials such as coal, wood, gas or diesel, but are also a natural by-product of cellular respiration in many living organisms.CO2 accumulates in steadily increasing concentrations in the earth's atmosphere as a result of combustion processes and is thus a major contributor to the greenhouse effect, because it absorbs some of the heat emitted by the earth and radiates it back. CO2 does not decompose itself, but is either physically stored by seas and oceans or broken down by plants during photosynthesis. The additional CO2 caused by humans can no longer be completely converted, which means that the carbon dioxide content in the atmosphere is constantly increasing. Since the beginning of industrialization alone, the global increase has almost quadrupled.CO2 emissions can be significantly reduced by using resources more efficiently and in line with demand in building operations. Simple measures already make buildings up to 40 percent more energy efficient. With the aedifion cloud platform, you can optimize your building operations in a data-driven and AI-based way.
