Focusing on what matters most

The same discipline and rigour that drives our science is reflected in our approach to environmental sustainability. Just as we seek to have a positive impact on the lives of patients and employees, and in the communities where we operate, we also strive to minimise our impact on the environment.

For years we have invested in sustainable innovations to reduce carbon emissions, water use and waste. And now we have achieved carbon neutrality. That means Biogen has effectively neutralised all the carbon emissions from sources associated with our business, including internal operations, purchased electricity, employee commuting and business travel, and suppliers of products and services.

Our strategic approach to environmental sustainability has contributed to the recognition we have received from global sustainability ranking and rating organisations.

  • In 2015, we were ranked number one in the world in Newsweek’s 2015 Green Rankings
  • In 2014, we were designated as the Dow Jones Sustainability Index World (DJSI World) biotechnology leader and named to DJSI North America for the fifth consecutive year
  • In early 2015 we were named as the most sustainable company in the world on the Global 100 list, issued each year by SRI rating organisation, Corporate Knights
