We feel a responsibility to drive positive change across the communities where we operate and on our planet. We recognize that the climate crisis is a health crisis, with a disproportionate impact on vulnerable communities. Our environmental, social and governance (ESG) commitments aim to advance a healthier, more sustainable and equitable world — one where science meets humanity.


In 2020, we announced targets for reducing our greenhouse gas emissions and our long-term vision to address fossil fuel emissions in our operations. Learn more about our climate goals and progress.


Water plays a critical role in many aspects of our business, including our production processes. We are working to reduce our water use and make sure it adheres to high quality and safety standards before returning it to the environment.

Learn more about our efforts to reduce water usage and address pharmaceuticals in the environment in our ESG Report.


Waste reduction enhances sustainability and can drive greater operating efficiency. We use the waste hierarchy, focusing first on reuse, composting and recycling.

We recognize that manufacturing medicines typically generates a large amount of waste relative to the amount of product produced. Minimizing waste reduces environmental impacts and disposal costs, resulting in more cost-effective production of medicines through a lower cost of goods. Biogen has applied metrics with targets to our manufacturing processes, tracking how much waste our processes generate and continuously working to improve efficiency.

  • We cut the total waste generated from our operations by 50% from 2019 to 2021.
  • We maintained a 100% diversion of waste from landfills in 2021.

Sustainable Drug Development

According to the U.S. Department of Energy, scientific labs use anywhere from five to 10 times more energy than typical office buildings1 and generate 5.5 metric tons of plastic a year2. Our Principles of Sustainable Drug Development aim to promote sustainability, process safety and efficiency in the ways we discover, develop and manufacture potentially life-changing therapies.
