Main FeaturesReporting, Accounting and statements

Klappir brings the structure and discipline of accounting into the world of sustainability. Designed to meet the rising demands of data transparency, regulatory compliance, and investor needs, Klappir’s Sustainability Accounting feature empowers organizations to record and classify.

In today’s complex sustainability landscape, having a single source of truth is essential. Klappir serves as the definitive data repository for sustainability related information, ensuring your data is accurate, consistent, and always up to date. By centralizing data collection and management, Klappir eliminates discrepancies and reduces the risk of errors, giving you a clear and unified view of sustainability performance. Our accounting principles are built to ensure full transparency, compliance, and trust, enabling businesses to report with confidence and adapt quickly to emerging regulations.

Accounting Core Principles

1. International Standards & Quality Control: All data structures, classifications, and conversion factors follow internationally recognized standards. Governed by ISAE 3000 certification and an annual review, no user can alter these settings independently, guaranteeing traceability, comparability, and integrity.
2. Activity-Based Data as the Foundation: Klappir prioritizes activity-based data (e.g., kg, m³, kWh) for calculations. Spend-based data is also accepted but clearly marked as “not-qualified,” ensuring clarity, especially for global operations where regional variations matter.
3. Long-Term, Secure Data Storage: All data and calculations are stored securely in the Klappir Platform for a minimum of seven years, ensuring full auditability. Data entry is traceable and conducted through defined methods within the platform.
4. Transparent Metrics & KPIs: All sustainability metrics and KPIs are stored for analysis and reporting. Any changes made during the reporting process are fully traceable, supporting complete transparency and compliance.

With automated workflows, real-time data access, and a built-in audit trail, Klappir reduces manual work and minimizes the risk of error. Its powerful classification and analytics tools give users deep visibility into their ESG performance, supporting strategic planning, compliance reporting, and stakeholder engagement.

Sustainability Accounting is no longer a secondary task, it’s a business-critical function. Klappir makes it possible to manage ESG data with the same integrity and operational rigor as financial data. The result? Smarter decisions, stronger compliance, and a measurable sustainability footprint that drives long-term value for the organization and its stakeholders.

Klappir's Reporting feature is designed for compliance with global standards such as the European Sustainability Reporting Standards (ESRS and VSME) and Nasdaq ESG frameworks. The Platform's advanced classification systems facilitate detailed analysis of ESG metrics down to specific assets or suppliers, enhancing transparency and comparability.​

Data you can trust

As sustainability reporting becomes increasingly regulated, scrutinized, and strategic, organizations need a solution that brings order, reliability, and efficiency to the process. Klappir delivers exactly that. With a fully standardized approach to Sustainability Statement disclosure, Klappir transforms ESG reporting into a consistent, data-driven, and business enabling practice. At the core of Klappir’s solution is a common structure used across the entire Klappir ecosystem. Every company on the platform operates under the same standardized data model and reporting format, ensuring that Sustainability Statements are fully comparable across entities, industries, and supply chains. This uniformity makes it easy to benchmark performance, identify risks, and collaborate with stakeholders based on credible, aligned insights.

One structure

But standardization doesn’t mean rigidity. Klappir offers full template customization, allowing organizations to design their own Sustainability Statement layout. This gives companies the flexibility to emphasize strategic focus areas and tailor communication to specific stakeholders without compromising compliance or consistency. Klappir’s platform goes further by ensuring that Sustainability Statements are automatically populated with verified, structured data. Whether the data originates from internal operations, suppliers, or partners, it flows through Klappir’s robust accounting engine, is tagged to specific assets or transactions, and is traceable for audits and reviews. The system ensures full data integrity and removes the manual burden of chasing inputs across departments.

Infinite clarity

Importantly, the Sustainability Statement’s reporting period can be aligned with your financial year, integrating ESG and financial reporting timelines into a single, efficient cycle. This alignment supports integrated thinking and simplifies executive oversight, compliance filing, and investor communication. Klappir is built for regulatory alignment with leading global standards, including the European Sustainability Reporting Standards (ESRS and VSME) and the Nasdaq ESG frameworks. The platform’s intelligent data classification and validation tools ensure every statement meets the expectations of auditors, regulators, and investors.

Proactive tool for growth

With standardized workflows, a user-friendly interface, and real-time dashboards, Klappir reduces the time and effort required for reporting while increasing precision, transparency, and traceability. More than just compliance, Klappir empowers organizations to turn ESG reporting into a strategic asset. By showcasing measurable sustainability performance, businesses strengthen trust with stakeholders, attract ESG-focused investors, and enhance their brand’s reputation.

With Klappir, sustainability reporting is no longer a reactive task, it becomes a proactive tool for growth, resilience, and long-term value creation. Join a future-ready ecosystem where every Sustainability Statement is clear, compliant, and powered by data you can trust.

ISAE 3000 The ISAE 3000 Type 2 attestation provides reasonable assurance on the design, implementation, and operational effectiveness of Klappir's controls over a specified period. Deloitte's evaluation encompassed a comprehensive review of Klappir's processes, including data and policy assessments, process walkthroughs, and performance observations of selected controls. Interviews with key personnel responsible for designing, implementing, and operating these controls were also conducted. This rigorous assessment ensures that Klappir's Sustainability Platform operates with a high level of data accuracy and integrity.

As an added layer of assurance, Klappir offers a dedicated Data Quality Control and Gap Analysis service. This includes a thorough review of your sustainability data, checking for completeness, consistency, and alignment with reporting requirements. We assess statement boundaries, validate critical data points, and identify gaps that may impact compliance or credibility. As part of this service, Klappir provides a formal Data Assessment Chapter within your Sustainability Statement, offering transparent insight into the integrity of your data.

This expert-driven process enhances audit readiness, supports regulatory alignment (e.g., CSRD/ESRS), and reinforces stakeholder trust in your sustainability disclosures.
