Green Genes

In 2003, Genentech employees formed the Green Genes group to help the company go green, and today it is our largest employee club with more than 4,000 employee members.

The mission of Green Genes is to:

  • Increase our employees’ knowledge and awareness of environmental sustainability.
  • Provide a forum to generate, exchange and evaluate sustainability ideas to improve the environmental performance of Genentech’s operations, our communities and our homes.
  • Have fun while leading by example in our industry.

Over the years, Green Genes’ focus on environmentalism has created broad changes in the company, including the expansion of composting and water and energy conservation programs. Green Genes has also spearheaded multiple landfill-reduction initiatives including a textile recycling drive, pen recycling, food waste minimization and encouraging employees to opt for reusable china instead of disposables in our cafeteria.

There are many ways for Green Genes members to get involved with our environmental programs including participation in numerous educational and volunteer opportunities, such as Eco Fairs, beach clean-ups and Lunch and Learns on topics ranging from beekeeping to electric vehicles.


“We started with composting and reusable water bottles and our effort has grown so that now being green is integrated into the work and our science – it’s the way we do business.”
–Katie Excoffier, Genentech Sustainability Manager
