Climate Action

Reversing the course of climate change is the goal that drives our work.

Xiongan New Area Plan

We are building a zero-carbon future.

SOM was one of the first design and engineering firms to join the World Green Building Council’s Net Zero Carbon Buildings Commitment. In 2022, we became a carbon neutral business by applying strategies to reduce emissions across our global operations, together with carefully selected carbon offsets as we continue to reduce our environmental impact. Among the other climate pledges that SOM has made are the AIA 2030 Commitment, the China Accord, and the SE2050 Commitment, which mandate stringent sustainability results for the projects that we deliver. As a member of the United Nations’ Race to Zero campaign, we are reinforcing these commitments in all aspects of our practice.

By 2030, we are targeting net zero operational carbon for 100 percent of our active work.

By 2040, we are targeting net zero whole life carbon for 100 percent of our active work.

Headquarters Building on Lake Geneva
Designed to reduce both embodied and operational carbon—all while harmonizing with its singular setting above Lake Geneva—this energy-efficient workplace building features a hybrid structure of concrete and mass timber.

The built environment accounts for 40 percent of carbon emissions worldwide. Imagine the impact if we could bring that number to zero. As an interdisciplinary design firm, we are channeling all of our expertise and resources to reach this goal—every day, our architects, engineers, and urban planners team up to meet the challenge. We approach every design project as an opportunity to accelerate the transition to a net zero carbon future, where human wellbeing and planetary health go hand-in-hand.

Through our built projects, our research initiatives, and our role as advocates in our industry and beyond, we are working to advance a net zero carbon built environment—and to create a more livable future for everyone.

We are building on decades of environmental leadership

In the 1960s, long before the threat of climate change was widely understood, Nathaniel Owings, SOM’s co-founder and a noted environmental activist, spoke to the profound responsibility that architects have to protect our planet’s limited resources. This conviction has guided our work ever since.

Civilizations leave marks on the Earth by which they are known and judged. In large measure, the nature of their immortality is gauged by how well their builders made peace with the environment.

We are developing new design solutions

As a research-based practice, SOM has a long history of advancing technological innovations that have transformed the architecture and construction industry. Today, we are applying decades of global experience to local contexts in order to address the climate and biodiversity emergencies.

We have demonstrated the potential for high-rise construction using mass timber, a far less carbon-intensive material than concrete and steel. We’ve also collaborated with manufacturers to design a prototype for efficient, low-carbon concrete construction. Partnerships with government agencies and universities have allowed us to advance our research. Working with U.S. Department of Energy’s Oak Ridge National Laboratory, we developed a concept for an energy-independent dwelling. We continue to lead research initiatives on carbon-sequestering materials, building systems, and technologies to advance decarbonization. We have implemented these solutions into hundreds of our own projects—from the first net-zero-energy school in New York City to the innovative timber construction of the main library in Long Beach, California.

Taking a comprehensive approach to carbon calculations has convinced us that a better model is needed across the industry. In 2023 we launched Whole Life Carbon Accounting, a system for evaluating and measuring whole life carbon emissions clearly and comprehensively, from the very start of a project and throughout its life cycle. And our adaptive reuse studio continues to help our clients find innovate solutions to renew, repurpose and extend the lifespan on the buildings that already exist, thereby reducing the embodied carbon impact of development.


We are driving change in the building industry

We cannot confront this challenge alone. Decarbonizing the building sector depends on everyone with a stake in the built environment—designers and developers, clients and contractors, institutions and governments, and finally, the people who use buildings and spaces—making this shared commitment and working together.

  1. SOM has authored or helped to launch major climate action initiatives, including the Carbon Leadership Forum’s MEP2040; ASHRAE Decarbonization Task Force; the World Business Council for Sustainable Development’s Decarbonizing Construction Guide; and the RIBA 2030 Climate Challenge.
  2. Individuals throughout our firm contribute their expertise and influence across the building industry worldwide—shaping policy, standards, and best practices. Members of our team hold leadership roles at organizations including the AIA Committee on the Environment, the UK Construction Industry Council, the City of Chicago Net Carbon Task Force, and more.
  3. Sharing knowledge maximizes the potential for impact, so we have created resources to promote progressive and sustainable building practices. These include an initiative to dechemicalize and decarbonize material specifications; design tools to advance active, passive, net zero design strategies; and an analysis tool to reduce embodied carbon in architecture, MEP, interior fit-outs, and structural design. By making the results of our research available to others, we aim to catalyze change throughout the industry.
