Sustainability (icon)

We are fully aware of our stakeholders’ high expectations regarding our products and processes. The quality and safety of our products, the safe and responsible operation of our facilities and the comprehensive protection of our employees and the people who live near our sites are of the utmost importance to us. Bayer also considers environmental protection and the responsible use of natural resources to be extremely important.

Responsibility for health, safety, environmental protection and quality ( HSEQ stands for health, safety, environment, quality. ) lies with the Group Board of Management. Group-wide HSEQ management systems are in place and incorporated into the business processes. Responsibility for steering and control lies with the two new corporate functions, “Health, Safety & Sustainability” and “Quality,” which stipulate responsibilities and framework conditions, among other things, through corporate policies, targets and performance indicators (KPIs).

Operational responsibility lies with the corresponding line organizations of the segments, which steer HSEQ independently with management systems, committees and working groups. All relevant HSEQ performance indicators from our production sites are compiled in a Group-wide Bayer site information system (BaySIS). The continuous review and revision of policies by the corporate functions, regular mandatory internal audits and external certification processes ensure that the systems at all production sites effectively meet the specific requirements in each case.

The excellent performance of our HSEQ stands for health, safety, environment, quality. management systems for the areas of health, safety, environmental protection and quality also reduces running costs by avoiding damage and disruptions to work and production.

Standards and certifications

Bayer’s HSEQ management systems are based on recognized international standards. Regular upkeep of the management systems and appropriate training and certification also underpin our commitment to the chemical industry’s Responsible Care™ initiative and in particular the guidelines of the Responsible Care Global Charter.

With regard to HSE management system coverage based on energy consumption, around 95% of all our production sites had an HSE management system audited by Bayer in 2016. Some 97% of our business activities were certified externally to at least one internationally recognized standard. A Group-wide certification plan aims to achieve virtually complete coverage in accordance with external standards in both environmental and occupational safety management by 2017. One hundred percent coverage is not feasible owing to the frequent changes in our site portfolio.

Pharmaceuticals and Consumer Health

The quality management system of these two segments forms the basis for the highest possible safety standards in the manufacturing of pharmaceuticals and medical devices, which are subject to strict quality requirements. It is therefore based on internationally recognized standards such as ISO (e.g. ISO 9001, 17025 and 13485) and ICH (International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use), as well as on rules for good working practice ( GxP is a collective term for all guidelines that govern “good working practice” and are particularly relevant for the fields of medicine, pharmacy and pharmaceutical chemistry. The “G” stands for “Good” and the “P” for “Practice,” while the “x” in the middle is replaced by the respective abbreviation for the specific area of application – such as Good Manufacturing Practice (GMP), Good Laboratory Practice (GLP), Good Clinical Practice (GCP) or Good Agricultural Practice (GAP). These guidelines are established by institutions such as the European Medicines Agency or the U.S. Food and Drug Administration. ) in the development and manufacture of pharmaceuticals (e.g. Good Manufacturing Practices (GMP)), Good Distribution Practices (GDP) and Good Clinical Practices (GCP). Compliance with the relevant standards is regularly audited by internal experts, regulatory authorities and external consultants. These audits also cover our suppliers and institutes sub-contracted by us.

Crop Science

Product manufacture at Crop Science is performed according to ISO 9001. Compliance with manufacturing standards and registered product specifications is regularly monitored by external auditors. All our products are approved/authorized by the relevant national authorities and thus fulfill the respective requirements with regard to quality and user safety.

Animal Health

Our veterinary medicine products also comply with stringent GxP quality standards stipulated in relevant statutory requirements applying to development, approval, manufacture, marketing and safety monitoring. According to this, safety is to be ensured for the animals to be treated, people and the environment alike. Within the scope of the statutory approval procedures and, if required, re-registrations, Animal Health carries out studies in order to verify the quality, efficacy and safety of its products. Regular official inspections and internal audits check compliance with legal requirements. The audits also cover institutes subcontracted by us, service providers and suppliers.


Covestro’s quality management system is certified to the international standard ISO 9001. Over 99% of reporting production and nonproduction sites worldwide are certified.
