Founded in Gaithersburg in 1988, MedImmune is pioneering innovative research and exploring novel pathways across key therapeutic areas, including respiratory, inflammation and autoimmunity; cardiovascular and metabolic disease; oncology; neuroscience; and infection and vaccines. The MedImmune headquarters is located in Gaithersburg, Md., one of AstraZeneca’s three global R&D centers.  MedImmune’s key products include Synagis®, the first monoclonal antibody to prevent serious lower respiratory tract disease caused by respiratory syncytial virus in children, and FluMist®, the intranasal influenza vaccine.

Environmental sustainability is an integral part of MedImmune's business strategy. In the same way that we innovate and set aggressive goals to generate new advancements in biopharmaceuticals, we continually seek to improve the resource efficiency of our operations and supply chain while managing the environmental impact of our products. We are committed to AstraZeneca’s 10-year global Safety, Health and Environmental (SHE) Strategy. Under this strategy, we support the following sustainability targets:

Greenhouse gas: 20% reduction in greenhouse gas footprint.

Waste: 15% waste reduction (hazardous and non-hazardous).

Water: Reduce water usage by 25%.

In addition to being a Montgomery County Certified Green Business, MedImmune is also a member of the Maryland Green Registry.

Energy & Carbon Emissions

Our Gaithersburg location has taken the lead for energy conservation at MedImmune. We set a site-specific goal of a 25% reduction in energy intensity by 2020. In the first three years after setting the target, the site has already achieved a 10% energy intensity reduction. Overall energy use at the site will fluctuate with expected growth and/or consolidation, but we will continue to drive improvements in our energy intensity through excellence in energy management.

MedImmune Gaithersburg has developed substantial partnerships with the Maryland Energy Administration and the U.S. Department of Energy (DOE) to develop an industry-leading energy management system.

  • First biotech company to receive certification under DOE ‘s Superior Energy Performance program (2014)
  • First biotech laboratory facility to implement the ISO 50001 energy management standard
  • Participation in DOE’s Better Plants program since 2010

Highlighted Initiatives

  • A large R&D laboratory expansion completed in 2011 earned Leadership in Energy & Environmental Design (LEED®) Gold certification for New Construction from the U.S. Green Building Council. The 324,000 square foot space uses 28% less energy per square foot than the rest of the main building.
  •  Exterior lighting retrofits helped reduce energy for that system by more than 45%.
  • 10% of electricity is purchased from renewable energy sources.
  • The Gaithersburg headquarters implemented an Electric Vehicle (EV) Charging Station Program in January 2011, installing eight units.


MedImmune’s Gaithersburg sites have implemented robust waste recycling programs for paper, cardboard, cans, glass and yard debris. Gaithersburg also recycles many other materials including construction debris, ink cartridges, composted food, batteries, light bulbs and electronics.

Waste reduction and sustainability is also a focus in MedImmune’s cafeterias. Composting in the cafeteria includes biodegradable kitchenware.  Our catering service focuses on local/seasonal/sustainable menu offerings. 

The employee fitness center was awarded LEED Gold certification in large part because of recycling of construction waste and use of products made from recycled materials.


In order to meet the corporate targets for reduction in water use, MedImmune’s Gaithersburg headquarters is currently implementing a water conservation plan. 

Employee Engagement

Every new hire at MedImmune receives information about environmental sustainability as part of orientation.  Gaithersburg’s Green Team meets regularly and plans both yearly events such as Earth Week observances and semi-annual “Office Swap” of unused supplies.  The Green Team also educates colleagues on good environmental practices at the office and at home.
