Limited Assurance Report of the Independent Auditor Regarding Sustainability Information¹

To the Executive Board of BASF SE, Ludwigshafen am Rhein

We have performed an independent limited assurance engagement on the qualitative and quantitative disclosures on sustainability published in the Online-“BASF Report 2019” (further “Report”) published under http://www.bericht.basf.com/2019/en for the business year from January 1 to December 31, 2019 of BASF SE, Ludwigshafen am Rhein (further „BASF“).

It was not part of our engagement to review product or services related information, references to external information sources, expert opinions and future-related statements in the Report.

Management´s Responsibility for the Report

The legal representatives of BASF are responsible for the preparation of the Report in accordance with the Reporting Criteria. BASF’s Report applies the principles and standard disclosures of the Standards of the Global Reporting Initiative (GRI), the Corporate Accounting and Reporting Standard (Scope 1 und 2), the Corporate Value Chain Standard (Scope 3) Standard of the Greenhouse Gas Protocol initiative by the World Resources Institute and the World Business Council for Sustainable Development (WBCSD), the recommendations of the European Chemical Industry Council (CEFIC), in combination with internally developed criteria for the evaluation method Sustainable Solution Steering, for climate protection products and the related prevented emissions as well as for the Health Performance Index as Reporting Criteria (further “Reporting Criteria”).

The responsibility includes the selection and application of appropriate methods to prepare the Report and the use of assumptions and estimates for individual qualitative and quantitative sustainability disclosures which are reasonable under the circumstances. Furthermore, this responsibility includes designing, implementing and maintaining systems and processes relevant for the preparation of the Report in a way that is free of – intended or unintended – material misstatements.

Independence and quality assurance on the part of the auditing firm

We are independent from the company in accordance with the requirements of independence and quality assurance set out in legal provisions and professional pronouncements and have fulfilled our additional professional obligations in accordance with these requirements.

Our audit firm applies the legal provisions and professional pronouncements for quality assurance, in particular the Professional Code for German Public Auditors and Chartered Accountants (in Germany) and the quality assurance standard of the German Institute of Public Auditors (Institut der Wirtschaftsprüfer, IDW) regarding quality assurance requirements in audit practice (IDW QS 1).

Practitioner’s Responsibility

Our responsibility is to express a conclusion based on our work performed within a limited assurance engagement on the on the qualitative and quantitative disclosures within the scope of our engagement.

We conducted our work in accordance with the International Standard on Assurance Engagements (ISAE) 3000 (Revised): “Assurance Engagements other than Audits or Reviews of Historical Financial Information” and the International Standard on Assurance Engagements (ISAE) 3410: “Assurance Engagements on Greenhouse Gas Statements” of the International Auditing and Assurance Standards Board (IAASB). These standards require that we plan and perform the assurance engagement to obtain limited assurance whether any matters have come to our attention that cause us to believe that the above mentioned sustainability information of the entity for the business year January 1 to December 31, 2019 has not been prepared, in all material respects, in accordance with the aforementioned Reporting Criteria. We do not, however, issue a separate conclusion for each disclosure. In a limited assurance engagement the evidence gathering procedures are more limited than in a reasonable assurance engagement and therefore significantly less assurance is obtained than in a reasonable assurance engagement. The choice of audit activities is subject to the auditor’s own judgement.

Within the scope of our engagement, we performed amongst others the following procedures:

• Inquiries of personnel on corporate level, which are responsible for the materiality analysis, in order to gain an understanding of the processes for determining material sustainability topics and respective reporting boundaries of BASF
• A risk analysis, including a media search, to identify relevant information on BASF sustainability performance in the reporting period
• Reviewing the suitability of internally developed Reporting Criteria
• Evaluation of the design and implementation of the systems and processes for the collection, processing and control of the sustainability disclosures included in the scope of this engagement, including the consolidation of the data
• Inquiries of personnel on corporate level responsible for providing the data and information, carrying out internal control procedures and consolidating the data and information
• Evaluation of selected internal and external documentation
• Analytical evaluation of data and trends of quantitative information which are reported by all sites for consolidation on corporate level
• Evaluation of local data collection and reporting processes and reliability of reported data via a sampling survey at the sites Ludwigshafen am Rhein (Germany), Kuantan (Malaysia), Antwerp (Netherlands), Shanghai BACH (China), Shanghai SBPC (China), Freeport (USA) und Geismar (USA).
• Review of the consistency of GRI Standards in-accordance option ‘Comprehensive’ as declared by BASF with sustainability information in the Report
• Assessment of the overall presentation of the disclosures.

As described in the BASF Report 2019, BASF engaged external providers to perform sustainability assessments and audits on suppliers. The adequacy and accuracy of the conclusions from these external assessments were not part of our limited assurance engagement.

Conclusion

Based on the procedures performed and the evidence obtained, nothing has come to our attention that causes us to believe that the qualitative and quantitative disclosures for the business year from January 1 to December 31, 2019 included in the scope of this engagement and published in the Report are in all material respects not prepared, in all material respects, in accordance with the Reporting Criteria.
