Core Features
AI-Powered Data Ingestion and Categorisation: A core differentiator of Greentally is its ability to ingest unstructured or semi-structured data files and automatically convert them into structured emissions records. Users can upload CSV exports, accounts-payable lists, invoices, utility bills, boarding passes and other documents; the platform’s large language models interpret the content, assign the correct Scope and category, and calculate the associated carbon footprint. This allows emissions calculations that previously took months to be completed in days.
Scope 1, 2 and 3 Emissions Calculations: Greentally calculates emissions across all three scopes, with particular emphasis on tackling Scope 3 supply-chain complexity. The dashboard highlights emissions by scope and category, and includes a supplier and value-chain overview to help organisations understand where emissions are concentrated.
Verified Emission Factors and GHG-Aligned Methodology: The platform combines AI with industry-verified emission factors, using recognised sources such as DEFRA and the US EPA, and aligns its calculations with the Greenhouse Gas Protocol. This is designed to ensure that results are transparent, science-based and suitable for compliance and assurance.
Real-Time Analytics and ESG Dashboards: Greentally provides real-time analytics on emissions, with dashboards showing total impact, emissions by activity, emissions by category and trends over time. Impact summaries and visual breakdowns make it easier for non-experts to interpret the data and identify priority actions.
Water Usage and Broader ESG Metrics: Beyond carbon, the platform offers water usage insights, monitoring and breaking down corporate water consumption. This supports a broader ESG view and helps organisations connect environmental metrics within a single interface.
Human-in-the-Loop Sustainability Services: Greentally’s model explicitly combines AI speed with human oversight. Sustainability analysts review AI-generated calculations, validate ESG reports and help clients interpret results. They also provide strategic guidance on reduction opportunities, roadmaps and alignment with regulatory frameworks.
ESG Reports and Regulatory Alignment: The platform delivers ESG and carbon reports intended to be compatible with major disclosure frameworks across regions. External descriptions highlight preparation for frameworks such as CSRD and CDP, allowing organisations to use Greentally outputs as the backbone of formal ESG and climate reporting.
Plans & Pricing
Greentally positions itself as an affordable, subscription-based carbon accounting platform. External startup intelligence sources describe a tiered model with Starter, Plus and Premium plans, offering increasing functionality and support for higher data complexity and reporting needs. Indicative price points are described in the low- to mid-hundreds per month, billed annually, although these details should be confirmed directly with the vendor as they may evolve.
The platform is explicitly marketed to small and medium-sized enterprises that find traditional carbon accounting too expensive or time-consuming, but can also support larger organisations seeking to streamline ESG reporting.
Integrations
Greentally focuses on flexible data ingestion rather than deep integrations into ERP stacks. Key integration approaches include:
File uploads (CSV, Excel, invoices, utility bills, boarding passes and other documents)
Accounting and finance exports (accounts payable lists, transaction data)
Potential connectors to common business systems, depending on client configuration
The primary integration strength lies in the AI engine’s ability to interpret unstructured input and map it to emissions categories, reducing the need for rigid, field-by-field system connectors.
Certifications & Awards
Greentally is part of the Y Combinator Summer 2023 batch, recognised as a climate and AI startup focused on making enterprise-grade carbon accounting accessible.
As of late 2025, there is no public evidence of B Corp status, ISO certifications or formal assurance of its methodology, although the company emphasises alignment with the GHG Protocol and use of verified emission factors. Organisations seeking audit-grade reporting will typically request methodology documentation and may choose to involve external assurance providers.
Expert Voices & Reviews
External partners and users highlight the role of Greentally in dramatically reducing the time and effort required for carbon footprinting:
A sustainability consultancy describes Greentally as a “game-changer” in carbon footprinting, emphasising that any document can be uploaded and interpreted by the platform, enabling completion of Scopes 1, 2 and 3 footprinting in days instead of months.
A collaboration with an accounting and advisory firm positions Greentally as the ESG software layer in joint offerings that combine financial expertise with automated ESG data and reporting.
In interviews, the CEO stresses that Greentally’s mission is to make robust emissions accounting accessible to SMEs, leveraging AI to automate tracking and help companies uncover reduction opportunities that would otherwise remain invisible.
Customers & Case Studies
Although detailed case studies are still emerging, public references show Greentally being used in partnership contexts and by SMEs:
A technology company’s sustainability report was prepared with a consulting partner, using Greentally for carbon footprinting, with the platform handling multi-scope calculations from diverse data files without overburdening internal teams.
Professional services and accounting firms partner with Greentally to deliver ESG data collection, automated ESG reporting and sustainability strategy to their own client base.
The platform is positioned for businesses that need to comply with climate-related tender requirements, investor expectations or upcoming regulatory frameworks while operating with limited internal sustainability resources.
Closing Insights
Greentally represents a new wave of AI-driven carbon accounting and ESG platforms focused on accessibility, speed and automation. Its strongest differentiators are:
AI-powered parsing of unstructured business documents
Full-scope coverage (Scopes 1, 2 and 3) with supplier insights
Verified emission factors and GHG-aligned methodology
A combined software-plus-expert model that blends automation with human oversight
For small and medium-sized businesses, this can be significantly more efficient than traditional consulting-only footprinting projects. For larger organisations, Greentally offers a way to accelerate data collection and standardise emissions reporting across teams and regions.
However, companies with highly specialised reporting needs, complex internal data architectures or requirements for integrated LCA, product-level footprints or deep supply-chain modelling may still need complementary tools. As with any AI-driven platform, transparency of emission factors, assumptions and models remains critical, especially when using Greentally outputs in regulated disclosures or audited ESG reports.
Overall, Greentally is a strong option for organisations that want enterprise-grade carbon accounting capabilities delivered through a modern, AI-enabled platform, with a particular fit for SMEs and advisory firms serving them.
