GSI has always focused on sustainable practices and solutions for the preservation and responsible management of our shared natural resources. We are working to incorporate more sustainability into our offices and daily operations; an effort that is spearheaded by GSI’s Green Team.


The Green Team consists of a group of staff tasked with examining our current practices and determining what we can do to become a more sustainably minded business. Since 2014 we have been working on achieving the City of Portland Sustainability at Work certification for our Portland, Oregon office. We are working to apply the same level of sustainability firm-wide, so that if it was available, our other offices would qualify for certification also. See a list of our sustainability achievements, on-going efforts, and future plans below.

What We Have Done

  • Instituted an extra recycling program to collect non-curbside recyclable plastics, Styrofoam, batteries, and ink cartridges (Portland office only).
  • Instituted an employee-led composting program for employees to take home food waste from the office kitchens for their home composting or recycling (Portland office only).
  • Recycle or refurbish all of the electronic devices that we use.
  • Completely eliminated the use of disposable dishware.
  • Four main office supplies (paper, binders, labels, and envelopes) contain at least 30% post-consumer recycled content.
  • Secure bike parking is available at all office locations.
  • Host annual Earth Week Challenge and EcoChallenge.
  • Offer a public transportation reimbursement program to all employee.
  • Incorporated videoconferencing technologies into all of our offices to reduce the need for travel.
  • Installed low flow aerators on bathrooms and kitchen faucets (Portland office only).
  • Host annual drives to support local charities both as a firm and financial support for charities that employees champion.
  • Host an annual EcoChallenge Event to educate and encourage staff to employ sustainable practices at work and at home.
  • Participating in city-sponsored and firm-sponsored commuter competitions.
  • Purchase carbon offsets from the Bonneville Environmental Foundation to offset 69% of out business-related travel. Business-related travel is the largest carbon producing part of our business.
What We Are Working On

  • Add aerators to faucets in all office locations to achieve greater water use efficiency.
  • Working to make sure that as many office supplies as possible contain at least 30% post-consumer recycled content.
  • Investigate ways to incorporate sustainability into more of our projects and project work.
  • Develop policy and options for using sustainable transit options for business-related trips.
