What does low carbon mean?

Low carbon means lower (lower) greenhouse gas (mainly carbon dioxide) emissions.

With the development of the world's industrial economy, the dramatic increase in population, the unlimited rise in human desires, and the uncontrolled production and lifestyle, the world's climate is facing more and more serious problems, and carbon dioxide emissions are increasing. , the earth's ozone layer is suffering an unprecedented crisis, and global catastrophic climate changes have repeatedly occurred, which has seriously endangered the human living environment and health and safety

Even the rapid growth or expanding GDP that mankind was once proud of has also greatly reduced due to environmental pollution and climate change. A life that reduces carbon dioxide emissions is called low-carbon life.

In addition to carbon dioxide, other gases include methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, etc.

Carbon dioxide has large global emissions, high warming effect, and long life cycle. It is the greenhouse gas that has the greatest impact on climate change. A research report from the Oak Ridge Laboratory in the United States shows that since 1750, the world has emitted more than 1 trillion tons of carbon dioxide, of which developed countries account for about 80%.

Low carbon connotation

Low carbon society, low carbon economy, low carbon production, low carbon consumption, low carbon life, low carbon city, low carbon community, low carbon family, low carbon Carbon tourism, low-carbon culture, low-carbon philosophy, low-carbon art, low-carbon music, low-carbon life, low-carbon survivalism, and low-carbon lifestyle.

Words such as "low carbon" and "carbon footprint" have become popular terms at home and abroad in recent years. "Carbon" here mainly refers to carbon dioxide gas. A life that reduces carbon dioxide emissions is called low-carbon life.

Physical Overview

Carbon compounds are generally obtained from fossil fuels, and then separated and further synthesized into various products required for production and life, such as plastics, benzene, etc.

Carbon exists in various forms, including crystalline elemental carbon, such as diamond and graphite; amorphous carbon, such as coal; complex organic compounds, such as animals and plants; and carbonic acid. Salt, such as marble, etc. The physical and chemical properties of elemental carbon depend on its crystal structure. High-hardness diamond and soft and smooth graphite have different crystal structures, and each has its own appearance, density, melting point, etc.
