Greenhouse gases, primarily CO2, have led to global warming and

extreme weather events, posing serious threats to human society[1]. Human

activities, especially energy-related activities dominated by the large-scale use of fossil fuels,

are the main cause of the rapid

increase

in atmospheric CO2 greenhouse gas concentrations[2]. According to 2018 public data

[3

], global

CO2 emissions reached 33.5 billion tons, with China accounting for 28.6%, ranking first

in the world. In 2020, China's GDP reached 101.6 trillion yuan, accounting for

17.42% of the global total, ranking second in the world. It is evident that China's carbon emissions per unit

of GDP are relatively high. From the 1992 United Nations Framework Convention on Climate Change to the 2015 Paris Agreement,

addressing global warming through carbon emission reduction has reached broad

consensus

worldwide,

proposing

the goal of

"limiting the global average temperature increase to well below 2°C

above pre-industrial levels

and pursuing efforts to limit the temperature increase to 1.5°C" by 2050. As of June 12, 2020,

125 countries have committed to achieving carbon neutrality by the middle of the 21st century.
