Choosing between sustainability management platforms is rarely a straightforward decision. The platforms that serve private equity firms collecting portfolio-level data operate differently from those built to help enterprises manage multi-framework regulatory reporting across departments. Before shortlisting any tool, it helps to understand where each platform was designed to perform and where it may fall short for your specific use case.
This comparison looks at two platforms that come up regularly in conversations about sustainability data management: Novata and KEY ESG. Both serve organisations that need to move beyond spreadsheets and manual reporting, but they have developed around distinct buyer profiles and operational priorities.
Novata
Novata is a sustainability data platform developed with a focus on private markets. It is designed to support private equity firms and their portfolio companies in collecting and aggregating standardised sustainability data, particularly in response to growing LP reporting demands and industry frameworks such as the EDCI.
The platform’s primary strength lies in its standardised data collection model. For PE firms looking to get consistent, comparable data across a portfolio with minimal configuration, Novata’s structured approach can reduce the complexity of initial deployment. Its alignment with common private markets reporting conventions makes it a recognisable option for firms operating within that ecosystem.
The trade-offs tend to emerge as reporting requirements grow more complex. Organisations that need to manage multiple regulatory frameworks simultaneously, run detailed Scope 3 carbon accounting across value chain categories, or support workflow-level compliance with approvals, evidence management, and audit trails may find the platform’s architecture constraining. Firms with enterprise reporting needs that extend beyond private market conventions, or that are scaling compliance across subsidiaries, jurisdictions, and non-ESG colleagues, often find they need a more flexible system.
Novata is a reasonable starting point for PE firms in the early stages of formalising ESG data collection. It is less well suited to organisations whose sustainability management requirements have grown to include multi-framework compliance, comprehensive carbon accounting, and audit-ready reporting across complex organisational structures.
KEY ESG
KEY ESG is a modular sustainability data management and compliance platform built for both enterprise organisations and investment firms managing portfolio-level reporting. The platform is designed to support the full sustainability management cycle: data collection, regulatory compliance, reporting, and performance improvement, within a single connected system.
The platform operates across two purpose-built products. The company platform supports in-house sustainability teams managing their own regulatory and voluntary reporting. The fund manager platform is built specifically for private equity and venture capital firms rolling up portfolio company data to fund-level reports, covering frameworks including SFDR and EDCI.
On the compliance side, KEY ESG supports a broad range of regulatory frameworks from a single data model, including CSRD, SFDR, IFRS S1 and S2, EU Taxonomy, TCFD, EDCI, and California Climate Disclosure Laws. The platform updates as regulations change, keeping organisations compliant without requiring manual reconfiguration.
Carbon accounting is comprehensive across all Scope 1, 2, and 3 categories, with calculations aligned to GHG Protocol methodology and access to over 70,000 emission factors from sources including DEFRA, US EPA, and Climatiq. The platform automates many of the Scope 3 categories and provides exportable audit trails, supporting both internal review and external assurance processes.
Workflow design is central to how the platform is built. Data collection tasks are assigned to specific users, progress is tracked centrally, and a 4-Eye Principle review process supports data sign-off before reporting. For CSRD compliance, the platform includes an in-platform double materiality assessment module aligned with European Sustainability Reporting Standards requirements. Audit trails are maintained throughout, providing the data lineage and evidence management that external auditors require.
The platform is designed to be used by non-ESG specialists, including finance, operations, compliance, and legal teams, not just dedicated sustainability managers. With 250 plus preset data points and unlimited custom metrics, organisations can configure the platform to their reporting needs without specialist implementation support.
KEY ESG is trusted by over 10,000 monthly active users with a 97% customer satisfaction rate. Clients include A.P. Moller Capital, Wittur, Svante, Iconic London, and Galileo Global Education, spanning private equity, manufacturing, technology, and consumer goods.
Comparing the two platforms
The clearest distinction between Novata and KEY ESG is the breadth of the compliance and workflow architecture.
Novata was built for standardised data collection in private markets. It does that job clearly and is a recognisable name in the PE ecosystem. Where it is less suited is in supporting the kind of comprehensive multi-framework compliance, Scope 3 depth, and workflow-level audit readiness that regulated enterprises and compliance-driven investment firms increasingly require.
KEY ESG was built to support both use cases simultaneously. A PE firm managing SFDR and EDCI reporting at fund level can run that alongside portfolio companies managing their own CSRD or IFRS obligations, all within the same platform. The modular architecture means the system adapts to organisational complexity without requiring reimplementation as requirements grow.
Which platform suits your organisation?
Novata is worth considering if:
- You are a PE firm in the early stages of ESG data collection
- Your primary requirement is standardised data aggregation across portfolio companies
- You are working primarily within private market framework conventions such as EDCI
KEY ESG is the stronger fit if:
- You need multi-framework compliance across CSRD, SFDR, IFRS, EU Taxonomy, and other regulations from a single system
- You require comprehensive Scope 1, 2, and 3 carbon accounting with full audit trail support
- You are managing sustainability data across multiple entities, jurisdictions, or departments
- You need the system to support non-ESG colleagues in collecting and validating data
- You are a PE firm that also needs to support portfolio company-level compliance alongside fund-level reporting
A note on what to ask during evaluation
When comparing platforms, the most useful questions to ask are practical rather than feature-level:
- Can the platform support all the regulatory frameworks relevant to your reporting cycle without additional configuration costs?
- How does the audit trail work, and what does an external auditor actually see?
- Who in your organisation will use the platform, and how much sustainability knowledge do they have?
- What happens when a regulation changes? Does the platform update automatically or require manual reconfiguration?
The answers to those questions reveal more about long-term fit than any demo walkthrough will.
