What is Unravel Carbon
Unravel Carbon is a carbon accounting software platform used to measure, manage, and report greenhouse gas (GHG) emissions across Scopes 1, 2, and 3. It supports corporate sustainability and finance teams with emissions calculations, activity-data collection, and reporting workflows for internal targets and external disclosures. The product emphasizes supplier engagement and Scope 3 data management, including tools to collect primary data and apply emissions factors where primary data is unavailable.
Scope 1–3 accounting coverage
The platform is designed to calculate and track emissions across Scopes 1, 2, and 3, which aligns with common corporate carbon accounting requirements. It supports activity-data based calculations and emissions factor application to convert operational and spend/supplier data into CO2e. This makes it suitable for organizations that need a single system of record for corporate emissions inventories and progress tracking.
Supplier engagement for Scope 3
Unravel Carbon includes workflows aimed at collecting supplier data for Scope 3 categories, a common challenge in carbon accounting programs. It supports outreach and data capture processes that can help move from estimated to more primary, supplier-specific inputs over time. This is particularly relevant for companies with large supply chains where supplier participation drives inventory quality.
Reporting and audit readiness
The product supports structured reporting outputs and documentation practices that help teams prepare for stakeholder requests and assurance processes. Centralizing calculations, data sources, and methodologies can reduce manual spreadsheet work and improve traceability. This is useful for organizations aligning carbon reporting with broader ESG reporting cycles and governance controls.
Data quality depends on inputs
As with most carbon accounting tools, output accuracy depends heavily on the completeness and quality of activity and supplier data provided. Where primary data is missing, the platform must rely on secondary data and emissions factors, which can introduce estimation uncertainty. Organizations may need additional internal processes to validate data and manage exceptions.
Integration requirements can be nontrivial
To reduce manual data collection, many deployments require integrations with ERP, procurement, travel, utilities, and supplier systems. The effort to map data fields, normalize units, and maintain data pipelines can be significant, especially for multi-entity organizations. Implementation timelines and ongoing administration may increase if source systems are fragmented.
Not a full EHS suite
Unravel Carbon focuses on carbon accounting and related reporting rather than broader EHS incident management, industrial hygiene, or operational risk modules. Companies looking for a single platform to cover both EHS management and carbon accounting may need additional software. This can lead to parallel systems and added governance work to keep data consistent.
