Environmental Commitment

We consider environmental stewardship a professional imperative. Mahlum’s community of practice fully embraces architectural principles and practices that respect the earth, show reverence for nature’s life-giving force, support learning opportunities connected to the environment and demonstrate best practice. We take seriously the responsibility to use resources wisely — re-using building materials, selecting locally made products, designing low-impact building systems and demanding resource conservation for all project types.

Within the firm and in collaboration with peer organizations, we continue to learn and evolve. Every day we dedicate time and talent to leadership in the arena of sustainability, using our skills and knowledge to lessen the impact of the built environment on the planet.

We have made a significant commitment to integrated design and energy performance goals in all our work. We also foster innovation through internally funded sustainable research projects, keeping our staff at the forefront of energy efficient design. As a tangible goal, we commit to meeting the 2030 Challenge, which focuses on achieving carbon neutrality through improved building performance and reduced energy consumption.

We apply equal rigor to resource conservation in
our own operations, and
seek out opportunities to do more with less. Mahlum was identified as a 2010 Portland Climate Champion by the BEST Business Center. This program recognizes businesses in our community that have taken comprehensive, concrete actions to reduce their carbon emissions, and are leading the way to a low carbon future.


All paper used in our printers/copiers contains 100% post-consumer recycled waste fiber and is Forest Stewardship Council certified. Many of our paper products are Green Seal certified and chlorine free. Some are even manufactured with 100% wind power. Only vegetable-based inks are used for Mahlum business papers.


Mahlum's priority is to compost first, recycle second, and trash last. Through composting and vermicomposting, we are successfully diverting 2/3 of our previous waste volume from the region's landfills. For several years, our staff have been re-using coffee grounds for garden mulch as part of our Garden Grounds program. Annually, this program diverts 468 gallons (72.8 cubic feet) of coffee grounds from the waste stream to feed our local ecosystem.
