Why Wave 2 Companies Should Already Switch Their Sustainability Reports to the CSRD Structure
A look at Wave 1 CSRD disclosure for Wave 2 CSRD companies.

Ignitis Group is the largest public company in the Baltic States. Headquartered in Vilnius, Lithuania, it is a renewables-focused integrated utility with a purpose to create a 100% green and secure energy ecosystem for current and future generations. AB “Ignitis grupė” is the parent company of the Group, which is responsible for coordinating the activities and transparent management of the Group companies. It focuses on increasing the Group’s efficiency, making significant contributions to the energy security and green transition in the region as well as providing competitive services to customers while ensuring sustainable long-term value growth.
Ignitis leads in sustainability reporting through disclosing to the CDP, the UNGC, and disclosing against the EU Taxonomy and the Corporate Sustainability Reporting Directive (CSRD). The CSRD is an EU directive that entered into force in 2023, and applies to both EU companies and non-EU companies, including those with an EU branch, that have significant operations in the EU. The ESRS (European Sustainability Reporting Standards) are developed by EFRAG, an independent organisation bringing together various stakeholders, and are adopted by the European Commission as delegated acts after scrutiny by the European Parliament and Council.
Ignitis uses Nossa Data’s ESG reporting platform to leverage its sustainability reporting to the CSRD and the CDP amongst other sustainability frameworks and standards.
Ignitis fell within the first wave of companies required to report under the EU’s CSRD. As a parent company, this meant producing consolidated, CSRD-compliant sustainability disclosures for the Group and reporting against the ESRS for the first time in its FY2024 Annual Report. Companies aligning to the ESRS, must disclose thousands of data points across material sustainability topics, structured around general principles (ESRS 1), general disclosures (ESRS 2), and the material topical standards. The ESRS cover four reporting areas: governance, strategy, impact, risk and opportunity management, and metrics and targets.
The ESRS were developed through a process involving exposure drafts and public consultation, ensuring that the final rules reflect broad stakeholder input. Sustainability disclosures must be included in the company’s annual management report, not as a separate document, and sustainability statements must be audited by third parties.
Following a double materiality assessment, Ignitis identified a set of material ESRS topics that needed to be reported consistently across the Group. The challenge was not only understanding what to report, but how to efficiently collect, manage and consolidate sustainability data from several Group companies across different teams and functions.
Manual processes and spreadsheets would not scale to meet these reporting requirements, particularly under the scrutiny and timelines of first-wave CSRD reporting.
Nossa Data worked closely with Ignitis’ Sustainability team to design and implement bespoke ESRS reporting templates within the platform, tailored specifically to Ignitis’ group structure and material topics.
The solution enables consistency, collaboration, and assurance:
This approach allowed Ignitis to centralise sustainability reporting while maintaining clear ownership at entity level.
"Implementing a centralised data system has significantly streamlined our operations and enhanced the accuracy of our reporting. Its user-friendly design enabled specialists across various fields within our Group to work efficiently and the system's robust data tracking and auditing functions have been crucial in achieving high-quality reporting results. Additionally, the team's dedicated support and responsiveness to our feedback have refined our workflow, ensuring alignment with our reporting objectives.“
