Unravel Carbon Agentic Sustainability Platform

Unravel Carbon is a Singapore-founded climate software company co-founded by Grace Sai, Marc Allen and Kevin Teng, backed by Sequoia, Y Combinator and ALPHA JWC Ventures. It helps companies measure, reduce and report emissions in a way that holds up to regulators, auditors and investors.

The platform combines enterprise carbon accounting with AI agents: a Sustainability Copilot, data collection and transformation agents, a gap analyzer, an insights and review agent and product intelligence. Core modules cover corporate carbon footprint, product carbon footprint, ISSB reporting and ESG reporting, with sector solutions for fashion and consumer goods, manufacturing, food and beverage and financial institutions. Customers shown include Officeworks, Big Dutchman, The Iconic, Arla and AIA.

• Sustainability Copilot: an AI assistant that answers questions and guides users through carbon and ESG tasks.
• Data collection and transformation agents: gather and normalise activity data from files and business systems.
• Corporate carbon footprint: Scope 1, 2 and all 15 Scope 3 categories with materiality assessment.
• Product carbon footprint: product-level emissions for consumer goods, food and manufacturing supply chains.
• ISSB and ESG reporting: a library of 170+ ESG metrics and disclosure outputs aligned with ISSB, TCFD and CDP.
• Enterprise controls: audit trail, approval workflows, API integration and single sign-on.

Vietnamese garment and footwear suppliers can compute product footprints requested by global brands. Listed companies preparing ISSB-aligned sustainability reports can consolidate group-wide emissions data. Banks can use the financed emissions add-on to measure portfolio emissions.

AI agents take over much of the manual work of collecting, cleaning and mapping activity data, which shortens reporting cycles. Scope 3 coverage across all 15 GHG Protocol categories, audit trails and AI-assisted validation help reports pass assurance. One platform serves carbon accounting, product footprints and ISSB or ESG disclosures. A vendor interview states that 54% of sustainability teams adopted its AI agents within six months.

ISSB-based climate disclosure is being adopted across Asia-Pacific, including Singapore, Australia and Japan, and large buyers increasingly ask suppliers in Southeast Asia for Scope 3 and product footprint data. Sustainability teams are small, so AI that automates data collection is becoming a key buying criterion.
