On April 18, BWTON Technology Co., Ltd., together with metro operators in Nanchang, Suzhou and other cities, launched a carbon reduction service for metro passengers. Each trip is now recorded in a personal carbon account, and passengers can use their points to borrow over 5,000 e?books for free. This is the world's first account system dedicated to metro passenger carbon emission management, and China's first public welfare initiative converting "green actions" into "tangible goods."

Yu Huaqiong, CEO of BWTON, said: "The personal carbon account will become the largest platform for measuring, trading, and sharing low?carbon living in public mobility, giving back to passengers through public welfare and promoting long?term industry development."

To encourage participation, BWTON and partner metros launched the "100,000?Trip Low?Carbon Challenge." Passengers who activate the carbon reduction function via the metro app and scan to pay will automatically join the challenge. When total challenge shares reach 100,000, a "Low?Carbon Public Welfare Library" is opened, allowing passengers to borrow over 5,000 e?books for free.

BWTON provides the technology for the personal carbon account, including visualization based on core algorithms that accurately present each passenger's reduction amount.

Professor Yang Xiaoguang of Tongji University commented: "The personal carbon account system integrates financial, public welfare, and sharing attributes. It collects green data from metro users, converts it into carbon reduction equivalents, awards points, and provides incentives. This is a national first."

As a branch of the carbon market, personal carbon accounts have great potential. Unlike corporate carbon markets, they leverage public participation and are expected to become a key force in achieving low?carbon goals, as well as an essential part of green finance and smart city development.

BWTON will integrate GIS, 5G, and big data to support metro owners in building a low?carbon consumption system based on MaaS platforms, and will develop personal carbon reduction algorithms and a closed?loop trading ecosystem. In the future, BWTON will launch city?specific low?carbon activities and open its carbon standards to buses, e?invoicing, and other green scenarios.

Founded in 2017 as a joint venture between CRRC and China UnionPay, BWTON is China's largest smart mobility platform operator. Its business covers rail transit, metros, buses, and other scenarios across 20 provinces and over 100 cities. It operates 34 urban rail transit projects and has built MaaS platforms in multiple cities, achieving multi?modal interconnection.

BWTON's "Digital Cloud Ticket" system, based on a digital middle office and cloud computing, shifts the focus from tickets to people, enabling personalized services and scenario?based ecosystems. It connects vehicles, stations, people, and services, achieving a convergence of travel, tourism, and commerce.

Professor Yang Xiaoguang noted that the Digital Cloud Ticket system not only provides stable application capabilities but also allows merchants to distribute ticket products and customize benefits. It can also support public welfare initiatives like the personal carbon account.

BWTON CEO Yu Huaqiong stated that the company is driven by creating customer and social value, integrating social responsibility into its business model to raise the green index of the rail transit industry and enhance passengers' sense of gain and happiness in pursuing smart mobility and a quality life.
