Recently, as climate change occurs rapidly, the international community is increasingly calling for the use of the term climate crisis rather than climate change. The Intergovernmental Panel on Climate Change (IPCC) has warned that if the average global temperature rises by 2℃ in the future, it will have a fatal impact on the global ecosystem. As the thawing of the Siberian permafrost, Antarctica, and Greenland glaciers accelerates, the Earth itself is in a vicious cycle of warming itself and facing catastrophe. Now, climate change is an international issue and must be solved in order to preserve the global ecosystem.

The biggest factor in such climate change is a large amount of continuously generated greenhouse gases. Recently, through the Paris Agreement on Climate Change, a universal system in which all countries participate has been prepared, and many countries are implementing the carbon emission trading system to mitigate greenhouse gas emissions.

However, in the conventional carbon emission trading system, the transparency of emission allocation and the reliability of emission monitoring are not secured, so companies participating in the emission trading system are complaining, and market activation is hindered by the instability of the carbon emission trading system.
