Protecting the Environment

We meet our responsibility to protect the environment in many different ways. We are continuously working to reduce the environmental impact of our business activities and develop product solutions that benefit the environment. For us, an efficient approach to raw materials and energy makes both ecological and economic sense. Our measures help reduce environmental impact and at the same time cut the costs associated with materials, energy, emissions and disposal.


Responsibility for steering and monitoring health, safety and environmental protection (HSE) across the Group lies with the enabling function of the same name. It establishes targets, key performance indicators and framework conditions in the form of corporate policies – such as "HSE Management and HSE Key Requirements" - and other measures. HSE management systems are integrated into business processes across the Bayer Group. Operational implementation is effected in the divisions. The continuous review and revision of corporate policies by the HSE function and regular mandatory internal audits and external certification processes ensure that the systems at all sites meet the requirements in each case. Read more about it in our Sustainability Report.


Climate Protection

Climate change affects us all and is one of the greatest challenges that humankind will face in the future. Bayer considers climate protection and the related reduction of greenhouse gas emissions to be a top priority. We anticipate that our business areas of health care and agriculture will be impacted by climate change but will also be part of the solution.


Disover more about our climate targets in our Sustainability Report, chapter 7.


Bayer supports the recommendations of the Task Force on Climate-Related Financial Disclosures (TCFD) with respect to reporting on this topic. In our report, we implement the 11 recommendations of the TCFD in the four categories of Governance, Strategy, Risk Management and Metrics & Targets. For more information, please see our separate TCFD report.



Our energy needs have the greatest direct impact on our greenhouse gas emissions. Production accounts for the most significant share of our energy requirement, which depends on the production operations at the sites and the depth of our value chain.


Among the targets we have set within the context of our climate strategy is to cover 100% of purchased electricity needs with renewable energies by 2030. To achieve this objective, we have produced a catalogue of criteria such as physical proximity to the production plant and additionality.


In 2020, around 6% of our purchased electricity was sourced from renewable energies. Around 94% of the electricity originated from other sources, such as fossil fuels or nuclear power. In 2020, we concluded supply agreements for electricity from renewable energies in the United States, Mexico, Spain and other countries. Compared with 2019 (39.2 petajoules), Bayer’s total energy consumption fell by 8.6% to 35.9 petajoules in 2020. This decline is primarily due to the COVID-19 pandemic, which has led to reduced production activities at some sites.


Energy management systems such as ISO 50001 also help to identify potential energy savings in production processes, as well as when developing new production processes and converting exist-ing ones. This not only conserves valuable energy resources, but also takes into account economic factors associated with long-term savings. In our Report to CDP we also describe projects to save energy that were implemented at various sites.

Greenhouse Gas Emissions

At Bayer, air emissions are primarily caused by the combustion of primary energy sources such as gas and oil. These are used to generate electricity, steam and auxiliary energy (such as for heating and cooling) for the production of our products. Further emissions derive from chemical processes in which coal and other energy sources are required to produce chemical reactions. Emissions are also generated through our vehicle fleet and in the extraction and processing of raw materials. In reporting greenhouse gas emissions, we take into account the recommendations of the Greenhouse Gas Protocol (GHG Protocol). Direct emissions from our own power plants, vehicles, waste incineration plants and production facilities (Scope 1) and indirect emissions from the procurement of electricity, steam and cooling energy (Scope 2) are determined at all environmentally relevant sites whose annual consumption exceeds 1.5 terajoules. In line with the GHG Protocol, we report indirect emissions (Scope 2) according to both the location-based and market-based methods .


Greenhouse gas emissions fell in 2020 compared to 2019 from 3.76 to 3.58 Million metric tons of CO2 equivalent.

Water – An Essential Resource


Water and Wastewater

Responsible water usage is a cornerstone of our commitment to sustainable development. Clean water in sufficient quantities is essential for the health of people, animals and plants. That is why it is crucial that industrial water usage does not lead to local problems such as a shortage of water for the people living in the catchment areas of our production sites. In our Water Position, we commit to complying with international, national and local legislation to protect water resources, using them as sparingly as possible and further reducing emissions into water.


In our water stewardship strategy, we address a variety of factors connected with water, from operational water use and innovative products such as seeds with a reduced water requirement to our commitment in the value chain and cooperation with partners. We support the CEO Water Mandate of the U.N. Global Compact with the goal of working with key stakeholders to develop sustainable strategies for water usage.

In our annual response to the CDP Water Disclosure, we report in detail on our water usage and the company-specific water footprint. This represents a progress report for the CEO Water Mandate. In recent years, including 2020, we have repeatedly been included in the CDP Water A List (leadership status).
