Bill
S 2127
Mass. bill S.2127 requires at least 30% embodied carbon reductions in eligible state-funded construction via mandated whole-building LCA or reuse strategies, with DCAMM rulemaking.
Note on source materials
- The packet you provided includes a header/title that appears unrelated to the bill text (a title about suspending travel to certain states). The full bill text included in your packet, and summarized below, is a Massachusetts state bill (S.2127) that would require embodied-carbon reductions in state‑funded construction projects. This summary is based on the bill text you supplied.
Summary — An Act relating to embodied carbon emission reductions in state‑funded projects (S.2127)
Purpose
- Require the Commonwealth to reduce embodied carbon in certain state‑funded construction and renovation projects by setting procurement and design compliance requirements. The Department of Capital Asset Management and Maintenance (DCAMM) must promulgate rules to achieve at least a 30% embodied carbon reduction for eligible projects.
Key definitions (selected)
- Awarding authority: state agencies contracting public works, institutions of higher education, certain natural‑resource agencies, other state entities receiving state funds for public works, and the Department of Transportation.
- Eligible project: new construction >50,000 gross sq ft; or renovation where >50% of assessed value is altered and project >20,000 gross sq ft of occupied/conditioned space.
- Covered products: structural concrete (ready‑mix, precast, CMUs, shotcrete), reinforcing steel (rebar, post‑tension tendons), structural steel (hot‑rolled sections, plates, metal deck), and engineered wood / mass timber (CLT, glulam, LVL, etc.).
- Embodied carbon: GHG emissions from harvesting, extraction, manufacture, transport, installation, maintenance, replacement, disposal of eligible products.
- Environmental Product Declaration (EPD): Type III EPD per ISO 14025 (or equivalent LCA methods meeting ISO data standards).
- Whole Building Life Cycle Assessment (WBLCA): cradle‑to‑gate or cradle‑to‑grave LCA per ISO 14040/14044 (operating energy excluded), comparable to a reference baseline per ASTM E2921‑22.
Key provisions
- Rulemaking deadline: DCAMM must promulgate rules within one year of enactment that collectively produce at least 30% embodied carbon reductions in eligible projects.
- Compliance pathways (awarding authorities must require one of the pathways from bidders):
- Performance pathway (WBLCA): Conduct a cradle‑to‑grave whole building LCA (ISO 14040/14044, excluding operating energy) showing ≥30% reduction in Global Warming Potential (GWP) versus a reference baseline building drawn from an LCA Commons/database. Software and datasets used must comply with ISO 14044, ISO 21930 and conform to ISO 21931; same tools/datasets for baseline and proposed building.
- Re‑use pathway: Demonstrate retention of at least 45% of the existing building’s primary structural elements and enclosure (foundations, columns, beams, walls, floors, lateral elements, roof framing, wall framing, exterior finishes). (Text truncated in packet; additional conditions likely follow.)
- Product‑level requirements: preference for EPDs (cradle‑to‑gate / A1–A3 stages) and other ISO‑compliant life‑cycle data; defines “responsible bidder” as the supplier or subcontractor manufacturing/providing the eligible product.
Who is affected
- State awarding authorities (DCAMM, agencies, higher ed, DOT, others) — will need to include embodied‑carbon compliance requirements in contract specifications.
- Design teams (designers of record) and construction contractors — must deliver projects meeting WBLCA or reuse targets.
- Material suppliers, manufacturers, and subcontractors — increased demand for EPDs, low‑carbon materials, or recycled/reused components; may need to provide LCA data.
- Project budgets and schedules — may incur additional design, LCA modeling, procurement, and documentation costs; potential long‑term lifecycle savings and emissions reductions.
Procedural / timeline notes
- Introduced: June 18, 2025. Status: Referred to the Senate Committee on Finance; previous referral to State Administration and Regulatory Oversight appears in the record. Hearing scheduled (per materials) for 07/15/2025.
- DCAMM must adopt rules within one year after enactment to implement the 30% reduction target.
- The provided bill text is truncated in places; final legislative text may add technical, enforcement, procurement, or compliance details not included here.
Potential impacts (practical)
- Environmental: Intended to lower embodied GHG emissions in large state construction/renovation projects (target ≥30%).
- Market: Increases demand for low‑carbon materials, EPDs, WBLCA expertise, and building reuse strategies (e.g., adaptive reuse, mass timber use, low‑carbon concrete/steel).
- Administrative/financial: Requires new procurement language, LCA performance verification, and possible upfront costs for modeling and materials; potential for long‑term benefits in emissions reductions and material cost stability.
Caveats
- This summary is based on the provided draft text (with some sections truncated). Final bill language and implementing regulations could change thresholds, compliance methods, verification procedures, cost‑recovery mechanisms, or enforcement provisions.
