California Transparency in Supply Chains Act

The California Transparency in Supply Chains Act of 2010 is designed to increase the amount of information made available by manufacturers and retailers regarding their efforts (if any) to address the issue of slavery and human trafficking, thereby allowing consumers to make better, more informed choices regarding the products they buy and the companies they choose to support. The following highlights Bayer’s global efforts in this regard.

Bayer supports the United Nations’ Universal Declaration of Human Rights and a number of globally recognized declarations for multinational enterprises. As a founding member of the United Nations Global Compact (UNGC) initiative, Bayer undertakes various measures to implement the 10 universally recognized principles in the areas of human rights, labor standards, environmental protection and anti-corruption throughout the organization when shaping business processes and strategies.

Promoting human rights standards internally and throughout all of Bayer’s business operations is in line with our Values and Leadership Principles, our Sustainable Development Policy and our group-wide Human Rights Position. Since 2017, Bayer has published a public statement based on the UK Modern Slavery Act to send a clear signal against slavery and servitude, forced or compulsory labor and human trafficking in its value chain. Bayer’s commitment to foster the implementation of human rights is supported through our Corporate Compliance Policy. It is in effect at all Bayer locations and it applies to Bayer’s business operations worldwide. Bayer will use this position as a framework to guide our decision-making and constructive engagement within our sphere of influence, while the responsibility of the governments of the various countries for protection of human rights is respected.

Bayer has combined all of its fundamental sustainability standards and requirements for its suppliers in a Supplier Code of Conduct. This code of conduct comprises the areas of ethics, labor, health, safety, environment, and quality as well as related management systems. Our Supplier Code of Conduct emphasizes international labor and human rights standards such as the principles of the UNGC and the International Labour Organization’s (ILO) eight core labor standards. Suppliers are expected to protect the human rights of their employees and to treat them with dignity and respect. Supplier employees shall have the right to freely choose employment, the right to associate freely and join or be represented by worker councils or labor unions on a voluntary basis, and the right to bargain collectively as they choose. Workers also have the right to a workplace free of harassment and unlawful discrimination.

In order to successfully address the diverse challenges of a sustainable supply chain and to leverage synergies together with other companies, we collaborate with the Pharmaceutical Supply Chain Initiative (PSCI) as well as with Together for Sustainability (TfS), an initiative co-founded by Bayer. In both initiatives, we focus on the standardization of sustainability aspects in the pharmaceutical and chemical industries in order to establish corresponding social, ethical and environmental practices among our suppliers. The exchange of supplier assessments and audits among member companies enables access to additional sustainability evaluations of suppliers who also work for Bayer. This minimizes the administrative burden for both suppliers and the member companies.

The Pharmaceutical Supply Chain Initiative is a group of major pharmaceutical companies who share a vision of better social, economic, and environmental outcomes for all those involved in the pharmaceutical supply chain. This includes improved conditions for workers (including freely chosen employment, no involuntary prison labor, abolition of child labor, and no use of forced, bonded or indentured labor), economic development, and a cleaner environment for local communities.

The Together for Sustainability initiative is a group of multinational companies that aims at developing and implementing a global supplier engagement program that evaluates and improves sustainability sourcing practices, including ecological and social aspects. The initiative is based on good practices and builds on established principles – such as the UNGC and the Responsible Care Global Charter as well as standards developed by the ILO, the International Organization for Standardization (ISO), Social Accountability International (SAI) and others.

Slavery and human trafficking can take many forms, including forced labor and child labor. We follow a clear ‘zero tolerance to child labor’ policy in our business operations worldwide. We do not tolerate child labor in our supply chain either, where we take action against known cases of violations. Our efforts to fight against child labor and forced labor are consistent with the ILO’s core labor standards and the UNGC principles.

Our efforts for more sustainability in the supply chain include:

  • Sustainability standards: Bayer regards adherence to sustainability standards within the supply chain as a crucial factor in the value chain. By acting responsibly in collaboration with our suppliers, we aim to minimize risks and create stable, long-term business relationships with our partners. For this reason, Bayer applies not just economic standards, but also environmental, social and governance (ESG) standards in choosing new suppliers or continuing its relationships with existing ones. These standards are defined in our Supplier Code of Conduct, which includes child labor avoidance and no utilization of slavery, forced, compulsory, bonded or indentured labor or involuntary prison labor as well as human trafficking in our supply chain. It is integrated into electronic ordering systems and contracts throughout Bayer. Furthermore, our standard supply contracts contain clauses that authorize Bayer to verify suppliers’ compliance with our sustainability requirements. The Supplier Code of Conduct is based on the principles of the UNGC and our Human Rights Position.
  • Supplier sustainability performance evaluation:The sustainability performance of our suppliers is monitored through online assessments and on-site audits. Suppliers are selected for these evaluations based on a combination of country and category risks as well as strategic importance in accordance with our Group targets. The assessments are carried out on our behalf by a leading web-based service platform for sustainability performance monitoring (EcoVadis). They are based on a web-supported, modular questionnaire completed by the supplier, coupled with accompanying verification documents and 360° screening. We conduct the on-site audits with external, independent auditors. Here, too, we apply the standard of the respective industry initiatives in which we participate in order to benefit from synergies. In addition, internal auditors perform inspections focusing on health, safety, and environmental protection. Among others, these audits are performed on contract and toll manufacturing suppliers with an increased risk potential. The assessment and audit results are thoroughly analyzed and documented. Wherever the results are unsatisfactory, we develop improvement measures together with our suppliers to ensure that they fulfill social, ethical and environmental standards in the future. In 2017, 3% of the evaluations had a critical result. These suppliers were requested by Bayer to rectify the identified weaknesses with the help of corrective instructions or action plans. In 2017, Bayer was not prompted to end a supplier relationship due solely to sustainability performance or serious sustainability deficiencies.
  • Training for procurement staff: We offer training activities to help procurement staff worldwide create awareness of sustainability and possible risks in dialogue with our suppliers. Training for procurement employees includes online courses dealing with the EcoVadis sustainability assessment process. In addition, we organize specific sustainability roadshows for different procurement categories and local procurement organizations (in 2017, i.e. in China and Switzerland), and provide information material. Within the scope of our supplier sustainability evaluations, we have identified a country risk particularly for India. In this connection, we carried out intensive workshops and training courses in India for our local procurement personnel.
  • Training for suppliers: We regularly provide information on sustainability to our suppliers through Supplier Days. This global and local dialogue is essential to build up reliable relations and to make the principles of our procurement policy and our sustainability requirements clear to our suppliers. In return, we would like to know more about the suppliers’ situation in order to be able to identify and remove obstacles in our collaboration at an early stage. In China, Bayer used its Supplier Day 2017 to communicate its sustainability requirements. And we also conducted supplier training and workshops in China and India in cooperation with PSCI and TfS. Furthermore intensive training courses for external auditors of the PSCI initiative took place in China and India. The continuous development of suppliers in terms of sustainability is also a key objective of the industry initiatives TfS and PSCI. The TfS initiative offers an online Supplier Academy providing trainings on the initiative, Sustainability in Supply Chains and the Sustainability assessment and audit process. Moreover, the TfS member companies organize joint supplier events with the aim to promote a mutual understanding on sustainability challenges and requirements in the supply chain. PSCI likewise promotes continuing supplier development by means of the comprehensive information provided on the PSCI website and interactive webinars. Furthermore, PSCI organizes supplier conferences providing intensive training on subjects such as occupational safety, health and environmental protection, as well as in labor law and corporate ethics.
