Windmills and global sustainability initiatives


Making a Positive and Sustainable Impact

Every day, we’re focused on doing our best work to address unmet medical needs while minimizing the impact on our environment. This means making the most of our shared resources so we can deliver more lifesaving medicines to patients.

What Is Green Chemistry?

The Green Chemistry movement is driven by scientists, researchers and engineers aiming to create alternative processes that protect and preserve natural resources while reducing toxic waste. At Gilead, it’s changing the way we produce lifesaving medicines in earth-friendly ways.

Meet the Team

Incorporating Green Chemistry and other sustainability efforts across all phases of our R&D is a team effort. Here are some of the people making it possible:

Our Global Commitment

From green buildings to renewable energy to responsible sourcing, our sustainability efforts are far-reaching and constantly evolving. We strive to provide a healthy and safe workplace evidenced by the strict environmental practices we hold true.


Targeted Goals

Reduce our global Scope 1 and 2 greenhouse gas emissions by 25% by 2025, compared with our 2016 emissions.
