Words such as "low carbon" and "carbon footprint" have become popular words at home and abroad in recent years. The "carbon" here mainly refers to carbon dioxide gas.

since the industrial revolution, due to human activities, especially the exploitation and burning of fossil energy such as coal, the content of carbon dioxide gas in the atmosphere has increased sharply, leading to global climate change characterized by climate warming. According to meteorologists, water vapor, ozone, carbon dioxide and other gases in the atmosphere can penetrate the short-wave radiation of the sun, warming the earth's surface, and at the same time preventing the earth's surface from emitting long-wave radiation into space, thus warming the atmosphere. Because the effect of carbon dioxide and other gases is similar to that of "greenhouse", it is called greenhouse gas.

in addition to carbon dioxide, other gases include methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, etc. Carbon dioxide is a greenhouse gas with great global emissions, high warming effect and long life cycle, which has the greatest impact on climate change. According to the research report of Oak Ridge Laboratory in the United States, since 175, the world has emitted more than 1 trillion tons of carbon dioxide, of which developed countries account for about 8%.

low carbon aims to advocate an economic model based on low energy consumption, low pollution and low emission, and reduce harmful gas emissions. In recent years, many fund products take the low-carbon concept as the investment target, which meets the requirements of green economy development and has achieved good results. HSBC Jintrust Low-carbon Pioneer is the first low-carbon economy concept fund in China.
