When the user uses the Laidianla App to charge his/her new energy electric vehicle, the App will issue "carbon reward points", which are carbon management points based on carbon calculation and analysis. When carbon reward points accumulate to a certain number, users can exchange them for gifts or donate carbon emission reduction volume to eco-friendly public welfare activities in the App. Such a scheme can guide the user towards green consumption and green practices. In the future, Laidianla App will connect the user's personal carbon emission reduction efforts with the carbon trading market. By that time, the incentive for personal emission reduction efforts will no longer be exclusively subsidized by the platform. Instead, it will become a sustainable behavior supported by the carbon trading market.
