Background

Carbon trading is a marketable solution for greenhouse gas emission reduction. China has carbon emission right trading markets aiming at high energy consumption industries such as power generation, building materials and steel, voluntary emission reduction markets aiming at industries such as wind power, photovoltaic and forest carbon sink, and carbon-based markets aiming at public lives and small enterprises. The carbon-based general market stimulates the public to form a green low-carbon life style through carbon assets, continuously accumulates carbon emission reduction in a large scale, and is an effective supplement for a total-amount-controlled carbon trading system. At present, the carbon general mechanism in China is still in an exploration stage, and related practices are mainly carried out on regional and small-range trial. The main problems with the existing carbon platform include: (1) the integral excitation mechanism is imperfect, the activity of the participants is low, and the platform operation difficulty is large. (2) The platform openness is not enough, the participation willingness of commercial institutions is low, and the carbon-market-benefit low-carbon scenes are few. (3) The platform has data barriers, the participation cost of users is high, and the scale of the carbon popularization business is not large.

Patent document CN112232955A (application number: 202011104282.1) discloses a public service system based on carbon trading, which comprises a low-carbon user behavior information acquisition subsystem, a carbon currency conversion subsystem and a carbon trading platform; the invention encrypts the low-carbon user behavior information based on the block chain encryption technology to ensure that the user behavior is not stolen, advocates and promotes low-carbon behaviors such as green travel, low-carbon life and green consumption by stimulating carbon currency conversion transaction, also relates to a carbon transaction platform based on APP building carbon universal system platform, develops functional modules such as 'carbon universal system' and 'carbon account', and the like, and comprises carbon universal system propaganda, low-carbon behavior data access, carbon account accumulation, public service exchange and commercial resource encouragement modes to form a carbon universal ecosphere of accumulation-exchange-consumption, and enables the carbon universal ecosphere concept to go deep into the daily life of common users by stimulation. The patent can provide comprehensive services participating in carbon popularization ecology for the public and can improve the participation enthusiasm of the public to a certain extent. However, the patent fails to consider an incentive method of a scene operator, and a public incentive method lacks a value-making mechanism and fails to technically guarantee fairness and justice of reward distribution; on the other hand, the patent fails to solve the problems of low participation willingness of the organization and high centralized operation difficulty, and does not relate to the improvement of system security and fairness.
