In this paper, we introduced "Environmental Contribution Points System", which was aimed at being able to grow Eco Users and reduce CO2 emissions. We made a CO2 database about the effect of reducing environmental load, taking advantage of Automobile Recycled Parts or proper maintenance. The load estimates CO2 quantification and it is used as "Eco Points" for users, who will purchase recycled parts or send their cars for maintenance. For example, in order to promote Environmental Contribution Points, we collaborated with Green Point Club, which had 12 organizations. It installed our database to show the amount of CO2 reduction and Eco Points each recycled auto parts.
