What are CO2 emissions? Definition and explanation:
CO2emissions refer to greenhouse gases produced by the combustion of various carbonaceous materials such as coal, diesel and gasoline, natural gas, wood or LPG. In the course of these processes, high volumes of CO are emitted2 (Carbon dioxide), which accumulates in the Earth's atmosphere in steadily increasing concentration. CO2 emissions are significantly involved in the so-called greenhouse effect. This leads to global warming with devastating consequences for the environment.
Carbon dioxide and its effect
Carbon dioxide is a naturally occurring gas and plays an important role in the metabolic processes of many creatures. In low concentrations, it is completely non-toxic to humans and animals. For example, the air exhaled by humans has a carbon dioxide concentration of about four percent. Plants, on the other hand, require carbon dioxide for photosynthesis, which in turn causes them to produce and release oxygen. While the natural CO2 has no negative impact on the environment, the gas produced by technical processes is problematic because it can not be neutralized by nature in such large quantities.
CO2 emissions and their negative impact on the climate
CO2 emissions come predominantly from stationary (ie carried out in plants) and mobile (in-vehicle) burning of fossil fuels. They account for more than 85 percent of all emissions worldwide and are considered to be the main cause of the anthropogenic greenhouse effect. This carbon dioxide molecules accumulate in the earth's atmosphere and absorb infrared light. This hinders the natural radiation of the heat supplied by the solar energy and thereby leads to an increase in the temperatures on the earth. In contrast to the natural greenhouse effect, the anthropogenic greenhouse effect causes considerable climatic problems. The biosphere can not or only badly adapt to the unnaturally rapid increase in temperature, which leads to climatically significant changes.
The reduction of CO2Since the nineties of the 20th century, emissions for climate protection have been a major concern of energy and climate policy endeavors. These include austerity measures such as statutory speed limits for vehicles and ships as well as building renovations and thermal insulation for a reduced use of heating systems. Other efficient solutions to reduce carbon dioxide pollution include decarbonisation of carbonaceous fuels, increased use and research of renewable energy, targeted measures to protect rainforests, and the creation of large forest areas. In addition, the energy efficiency of each individual plays an important role, ie the consistent saving of electricity, water and fuel in everyday life.
