Sustainability reporting has evolved beyond a purely regulatory obligation and is now a key source of information for banks, investors, customers, business partners, and other stakeholders. There is a growing expectation for reliable, structured, and verifiable ESG data.

Whether your company is subject to mandatory reporting requirements or preparing voluntary basis, high-quality sustainability data can strengthen stakeholder confidence and support more informed business decisions.

How can BDO help?

We support our clients throughout the entire sustainability reporting journey—from defining the reporting framework and establishing governance and data collection processes, to preparing the sustainability report and assisting with its publication.

Our objective is to help companies build sustainability reporting processes that are not only compliant, but also transparent, auditable, and capable of supporting long-term business value.

Our services include:

• Scoping and applicability assessment of the CSRD, ESRS, the Hungarian ESG Act, voluntary frameworks, and stakeholder expectations.
• Gap analysis to identify existing data, processes, and areas for improvement.
• Double materiality assessment (DMA) and prioritisation of ESG topics.
• Establishment of governance structures, roles and responsibilities, data management processes, and internal controls.
• Preparation of the sustainability report or ESG disclosures.
• Assurance readiness and support during external assurance or certification processes, where required.
