BASF Flags Volume and Complexity as Key Challenges in ESRS Implementation

Chemical giant BASF, one of Europe's largest industrial companies, is navigating the European Sustainability Reporting Standards ahead of mandatory compliance, citing the sheer volume of quantitative and qualitative requirements as its primary operational challenge. The company began a gap analysis in December 2022 and established monthly pulse-check meetings with topic leads across its business to manage the implementation workload.

BASF's sustainability reporting head Tanja Castor described the ESRS as a significant step up even for a company with over 20 years of ESG reporting experience. The standards impose highly complex double materiality requirements demanding far-reaching quantitative impact assessments across the entire value chain. Castor noted ambiguities remain around how mandatory cross-references between standards should appear in integrated reports, and that auditors themselves face uncertainties because ESRS definitions and concepts differ from previously recognised frameworks.

BASF supports the goal of standardised and comparable sustainability reporting, arguing it enables capital market participants and civil society to holistically assess a company's performance, risks, and opportunities. However, the company cautions that true comparability will take several years to develop due to differing interpretations in the first reporting cycles. BASF also highlights potential competitive disadvantages from highly granular environmental disclosures at site or country level, which could allow competitors to draw conclusions about plant utilisation or production volumes.

CDP noted that its 2024 questionnaire will align with the ISSB climate standard IFRS S2 and that by end-2024 it plans to deliver the first ISSB-aligned corporate environmental dataset to market. CDP is also beginning alignment with ESRS and the TNFD framework. BASF's advice to peers starting their ESRS journey: build cross-functional working groups bridging sustainability and finance departments, since robust internal data-gathering and control systems — already standard in financial reporting — are a prerequisite for successful ESRS implementation.
