777Recently, BestSign, a leading e-signature provider in the Asia-Pacific region, visited Carbonstop, a renowned Chinese one-stop carbon management solutions provider. The two parties held a strategic cooperation signing ceremony at Carbonstop’s carbon-neutral office and toured its low-carbon workspace, experiencing firsthand the practical outcomes of a carbon-neutral office environment. They officially announced a strategic partnership aimed at jointly advancing measurable, reportable, and verifiable carbon emission reductions in the e-signature industry, helping enterprises align their digital transformation with low-carbon development.

As a leading AI-powered e-signature cloud platform in the Asia-Pacific region, BestSign redefines intelligent contract lifecycle management through its proprietary industrial mutual-trust e-signing network, global solutions, and its out-of-the-box Legal AI Agent product. Its services span over 40 countries worldwide, serving 5.84 million businesses and 346 million individual users—including 222 Fortune 500 companies as paying clients.
By digitizing paper-based contracts, BestSign promotes sustainability and reduces carbon emissions across the entire industry. In early 2024, BestSign estimated that saving paper is only one part of a paper contract’s “carbon footprint.” When factoring in printing, mailing, and other associated activities, the full carbon footprint of paper contracts translates to approximately 4 million tons of CO₂ equivalent emissions avoided annually by BestSign—equivalent to generating RMB 250 million in annual green value for society. By mid-2025, the total number of e-contracts signed via the BestSign platform surpassed 18 billion. If converted into equivalent paper contracts, this would save 252.7 billion sheets of paper, protect 8.424 million trees, and reduce annual carbon emissions by 16,848 metric tons. This “Green Contract Highway”, built by BestSign, is now safeguarding operations across more than a dozen sectors, including consumer goods, manufacturing, finance, new energy, and agriculture.
As a well-known domestic provider of integrated carbon management solutions, Carbonstop has long been committed to helping enterprises quantify, analyze, manage, and reduce carbon emissions. Leveraging its extensive industry experience, Carbonstop will provide BestSign with professional carbon reduction quantification services.
The Carbonstop team has precisely calculated “the amount of carbon emissions reduced per e-contract compared to a paper contract” for BestSign’s customers. This means every contract signed by a customer comes with its own “carbon reduction report card,” making green commitments vivid and visible. Both enterprise clients and individual users can clearly see their contributions to carbon neutrality through everyday business activities. This model—where “signing equals carbon reduction” and data is fully traceable—not only turns the concept of green office practices into quantifiable action but also reshapes how businesses perceive contract management: e-signing is no longer just a tool for efficiency but a critical vehicle for implementing corporate ESG strategies.

As an innovator in the e-signature space, BestSign has long transcended the boundaries of single-enterprise contract management, building an industrial-scale signing network that spans multiple industries and scenarios—from collaborative contracting across supply chain partners to cross-sector ecosystem agreements. This network, like capillaries, connects millions of enterprises and individuals, enabling faster and more transparent transmission of commercial trust. The partnership with Carbonstop now injects “carbon neutrality vitality” into this mature interconnection network—by deeply embedding carbon accounting into every interaction, the original trust-based industrial linkage will evolve into a green value chain connecting the future.
Today, green development is no longer a national agenda alone but a universal language of global commerce. BestSign, with its deep technical expertise in e-signatures, already serves numerous multinational corporations through a secure, compliant, global signing network that supports multilingual and multi-jurisdictional scenarios. Meanwhile, Carbonstop—the only Chinese carbon management provider featured on Gartner’s recommended list—boasts a global carbon database with over 510,000 data points and serves thousands of clients, many of whom are internationally oriented. The synergy of their capabilities will forge a distinctive Chinese solution: not only expanding service scope and capacity, but also marking a significant step toward globalizing China’s green tech standards.
“Making every e-contract a green pass is just the beginning of our collaboration with BestSign,” said Yan Luhui, Founder and CEO of Carbonstop. Against the backdrop of dual drivers—digitalization and decarbonization—Carbonstop and BestSign will deepen collaboration across multiple dimensions to deliver innovative solutions that help enterprises enhance operational efficiency while achieving green growth, jointly advancing toward a more sustainable future.
