Total Prize Money


Unlike operational carbon emissions, which can be reduced over time with building energy efficiency renovations and renewable energy, embodied carbon emissions from building materials have irreversibly entered the atmosphere as soon as a building is built. That means the upfront building material choices are critically impactful. And as new construction operations become more efficient, embodied carbon impacts become even more significant. On current trajectories, Architecture 2030 estimates embodied carbon will be responsible for almost half of total new construction emissions between 2020 and 2050.

MassCEC has engaged Built Environment Plus (BE+) to conduct an Embodied Carbon Challenge for actual new construction and major renovation projects in process or built in Massachusetts.

At least 5 prizes will be reserved for Lead Applicants who have not performed Whole Building Life Cycle Assessment (WBLCA) previously.

The Embodied Carbon Reduction Challenge Has Two Goals

Goal 1:

Assist design teams in gaining expertise to advise clients about options for reducing embodied carbon including using tools to estimate embodied carbon impacts

Training and Resources

BE+ will host a series of events and trainings including an overview of embodied carbon tools for different design phases, tips and tricks for Tally LCA and One Click LCA, case studies and more.

BE+ has licenses to Tally LCA and One Click LCA available for the duration of the Challenge for participants. For access click Express Interest

Goal 2:

Demonstrate low-cost, high impact changes that significantly reduce embodied carbon


Deadline March 31, 2024

Each project is required to be submitted by a Lead Applicant. The Lead Applicant can be:

  • Any company/person on the Design and/or Construction Team including the Owner.
  • Must have approval from the project Owner and be in coordination with other team members. 
  • It will be up to the discretion of the Lead Applicant how the prize is allocated to other team members.
  • A Lead applicant can submit more than one entry and be on more than one team.
  • A Lead Applicant will only be awarded a prize as the Lead Applicant once. The Lead Applicant can be on an additional winning project as a non-lead applicant team member.
Challenge Participation Requirements
  • Lead Applicants must complete the Notice of Interest form on the Built Environment Plus website.
  • Each Lead Applicant must send at least one employee to at least 3 of the designated related trainings offered by BE+ over the course of the Challenge.  See more information on training opportunities starting May 2023 on the BE+ website.


Judges will score the projects on a scale of 0-100 using the following criteria.

BE+ in collaboration with Brightworks will review all submissions prior to sending to the Judging Panel.

A panel of embodied carbon experts will serve as the judges, review the projects and determine the 2 grand prize winners and other projects to recognize.

BE+ will update this page with the judging panelists.

BE+ will announce the winners at an in-person celebration planned for May 2024. Following the celebration BE+ will issue the prize money to the Lead Applicants on the winning projects.

All prize winners will receive graphic from MassCEC showing recognition level/prize awarded in addition to cash prize.  Graphic  may  be included on company website and  marketing materials.

How to Participate

Submissions Requirements

1. Participation and Awards Submission is FREE.

2. Complete this Notice of Interest Form. Participants who complete this form will receive communication regarding the Challenge, available resources, educational opportunities and more.

3. Participants will submit the following for consideration:

    • Whole Building Life Cycle Assessment Reports for the baseline and proposed / actual building. This is expected to be completed in Tally or One Click LCA unless otherwise approved by Built Environment Plus. See WBLCA requirements below.
    • Carbon Leadership Forum WBLCA Reporting Template for baseline and proposed.
    • A Digital Poster that describes the project and Embodied Carbon reduction strategies. The poster must include a stacked bar chart of the proposed vs. baseline in units GWP/m2 broken down by foundations, structure, enclosure, interiors, site/landscaping, MEP, and FF&E as applicable.
    • Written text giving a project and team overview. Descriptions of how the reduction strategies are replicable and cost effective, innovative both in terms of design process and implementation, and an explanation of the embodied carbon reduction strategies. The Lead Applicant must also attest to having attended at least 3 of the Challenge events.
Requirements for Whole Building Life Cycle Analysis (WBLCA)

Conduct a cradle-to-grave life-cycle assessment of the project’s structure, foundations and enclosure consistent with LEEDv4 Materials and Resources Building Life-Cycle Impact Reduction Credit requirements and demonstrate a reduction for Global Warming Potential (GWP) compared to an equivalent baseline building.

The scope of the assessment should include, at a minimum, the following:

  • Life cycle stages: A1-A3, A4, A5, B4, C1-C4
  • Physical Scope: Substructure, Superstructure, Exterior Enclosure
  • Environmental Indicators: Global Warming Potential (GWP)

The baseline and proposed buildings must be of comparable size, function, orientation, and operating energy. The service life of the baseline and proposed buildings must be the same and at least 60 years to consider impacts from replacement and end-of-life. Baseline assumptions must be based on industry standard design and material selection for the project location and building type. The team must use the same life-cycle assessment software tools and data sets to evaluate both the baseline building and the proposed building, and report the Global Warming Potential (GWP) impact category at a minimum. Data sets must be compliant with ISO 14044.

Each applicant’s WBLCA will be reviewed by a third party to ensure appropriate and consistent expectations in terms of embodied carbon calculations and assumptions for judges of the competition.

BE+ will not accept responses past the deadline.
