SE 2050 stands for the Structural Engineers 2050 Commitment Program that is in response to the SE 2050 Challenge issued in 2019 by the Carbon Leadership Forum (CLF) and the SE 2050 Commitment Program developed by the Sustainability Committee of the Structural Engineering Institute (SEI) of the American Society of Civil Engineers (ASCE). This site is dedicated to the SE 2050 Commitment Program or the SE 2050 Commitment for short. This comprehensive program has been designed to ensure substantive embodied carbon reductions in the design and construction of structural systems by the collective structural engineering profession.
The SE 2050 Commitment Program is being developed in response to the SE 2050 Challenge which states:
All structural engineers shall understand, reduce and ultimately eliminate embodied carbon in their projects by 2050.
In December 2019 the SEI Board of Governors endorsed the vision of the SE 2050 Challenge by stating:
We, the Structural Engineering Institute (SEI) of the American Society of Civil Engineers (ASCE), support the vision and ambition of the SE 2050 Challenge. We, as a leading structural engineering organization in the United States, recognize the need for coordinated action across our profession to achieve the globally stated goal of net zero carbon by 2050.
The goal of the Program is to provide an accessible sustainability program, for individual structural engineers and structural engineering firms, with an accountable commitment strategy of active engagement on projects and sharing of information all in the name of achieving zero net carbon structures by 2050. The basic aims of the Program are to: Educate the structural engineering profession on the best practices of sustainable structural design and construction that will lead to net zero embodied carbon by 2050; Engage in an embodied carbon tracking program within the structural engineering profession thereby enabling the establishment of appropriate embodied carbon reduction targets until net zero is realized; Report on the current embodied carbon impacts and trends of various structural systems for different regions throughout the country; and Advocate and communicate with clients, the design community, and the public to build an understanding about embodied carbon and impacts of the built environment.
Through this process we will be able to track the embodied carbon impacts of our structural systems, assess the trends for various systems and then establish achievable reduction targets over time. This concept is modeled after the Architecture 2030 reduction targets for operational energy; SE 2050 will run parallel with this for structural embodied carbon. See figure.
Within the Program are three strategic areas of focus: Plan, Implement, and Share summarized below:
Plan: Individuals and firms commit to establishing an Embodied Carbon Action Plan (ECAP) and providing staff with education in the field of embodied carbon including life cycle assessment (LCA).
Implement: Engage in sustainable goals of projects, specify low carbon impact materials, and assess and understand the embodied carbon impact of projects using LCA methods.
Share: Share embodied carbon data of your structural systems to a central database for understanding national trends and developing appropriate reduction targets.
It’s well documented that we must be a carbon neutral society by 2050 if we are to avoid irreversible detrimental impacts to our environment.
Net zero means to SE 2050 that the total impact of all components of the structural system net to a zero embodied carbon impact when considering all stages of a building’s life-cycle. Our vision is net-zero embodied carbon structural systems by 2050.
Getting to net zero will require changes in both our design and construction methods as well in areas where structural engineers may feel ‘there isn’t anything we can do’. We as structural engineers are responsible for educating our industry on opportunities for embodied carbon reductions including demanding the availability of both production and documentation of lower impact materials. After all, any changes to structure as it relates to embodied carbon must be approved by the Structural Engineer of Record.
