Low carbon, English is low carbon.

Meaning lower (lower) emissions of greenhouse gases (mainly carbon dioxide).

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. Carbon dioxide emissions are increasing, and the earth's ozone layer is suffering unprecedented consequences.

Crisis and global catastrophic climate change have repeatedly occurred, which have seriously endangered the living environment and health and safety of mankind. Even the rapid growth or expanding GDP that mankind was once proud of has been greatly reduced due to environmental pollution and climate change.

A life that reduces carbon dioxide emissions is called low-carbon life.

Introduction Editor 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.

[2] Since the Industrial Revolution, due to human activities, especially the mining and burning of fossil energy such as coal, the content of carbon dioxide gas in the atmosphere has increased dramatically, leading to global climate change characterized by climate warming.

According to meteorological experts, gases such as water vapor, ozone, and carbon dioxide in the atmosphere can transmit short-wave radiation from the sun, heating the earth's surface, and at the same time block the earth's surface from emitting long-wave radiation into space, thus heating the atmosphere.

Because this effect of gases such as carbon dioxide is similar to that of a "greenhouse", they are called greenhouse gases.

[2] 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%.

[2] Low carbon aims to advocate an economic model based on low energy consumption, low pollution, and low emissions and reduce harmful gas emissions.

In recent years, many fund products have used low-carbon concepts as investment targets, which meet the requirements of green economic development and have achieved good results. HSBC Jinxin Low Carbon Pioneer is the first low-carbon economy concept fund in China.

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 ethylene, plastics, 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 carbonates, such as marble.

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.

The chemical properties of elemental carbon are inactive at room temperature and insoluble in water, dilute acids, dilute alkali and organic solvents; it reacts with oxygen at different high temperatures to generate carbon dioxide or carbon monoxide; among halogens, only fluorine can directly react with elemental carbon; under heating

, elemental carbon is more easily oxidized by acid; at high temperatures, carbon can also react with many metals to form metal carbides.

Carbon is reducing and can smelt metals at high temperatures.

The so-called low-carbon life means to minimize the energy consumed in daily life, thereby reducing carbon dioxide emissions.

Chemical element chemical symbol: C element atomic weight: 12.01 [1] Uses of charcoal Charcoal is an indispensable and important material in the national economy.

The original purpose of charcoal is fuel. Because charcoal is flammable, flame-resistant, has low ash content, and contains no sulfur, it has always been a high-quality fuel.

Due to its unique microporous structure and super adsorption capacity, charcoal is widely used in many aspects such as food, pharmaceuticals, chemical industry, metallurgy, national defense, agriculture and environmental protection.
