Contributing to sustainable development has become a core element of Bayer’s corporate strategy. We are increasingly focusing our activities on providing more people in all the regions of the world with access to health care and food and devising solutions to the challenges presented by climate change and protecting the environment.



Bayer's Industry-Leading Carbon Initiative

Bayer takes steps to make carbon sequestration a farmer’s newest crop opportunity.



There is no innovation without collaboration! We’d love to work with you to create solutions for a better life in the fields of health and agriculture.



Benefits of GMOs

Genetically modified crops (also referred to as genetically engineered or GMOs), help farmers to maximize each acre of farmland and reduce resources – water, land, energy - required to produce our food, fuel and fiber. GMOs are an important tool for farmers to maintain their land and grow food more sustainably.

Bayer Bee Care Program

The Bayer Bee Care Program was established to find solutions to bee health challenges. The program brings Bayer’s extensive bee health experience and knowledge under one coordinated platform. Bayer has proudly dedicated more than 30 years to ensuring the protection of pollinators.



Transparency at Bayer

We believe in doing things responsibly. We set high ethical standards that represent how we measure ourselves and our partners. Through greater efforts in transparency, we can work together to turn the impossibilities of today into the breakthroughs of tomorrow.
