Buy Clean Legislation: What Precast Manufacturers Need to Know About EPD Requirements
How low-carbon procurement policies are reshaping the precast concrete market
Buy Clean & Low-Carbon Procurement
Written by the IntraSync Engineering Team | Reviewed by Zachary Frye, CTO & Founder (7+ years precast industry experience)
Buy Clean legislation is transforming how government agencies procure construction materials, with concrete products at the center of these policies. For precast manufacturers, understanding these requirements isn't optional - it's becoming essential for accessing a growing segment of the market.
What is Buy Clean?
Buy Clean refers to procurement policies that require government-funded construction projects to consider the environmental impact of building materials. These policies typically require Environmental Product Declarations (EPDs) and may set maximum Global Warming Potential (GWP) thresholds for eligible products.
The concept originated in California with the 2017 Buy Clean California Act, which established GWP limits for structural steel, flat glass, and mineral wool insulation used in state projects. Concrete and cement were added in subsequent legislation, and the model has spread to other states and the federal level.
The Buy Clean Wave
Buy Clean policies are expanding rapidly:
- Federal: Federal Buy Clean Initiative (2022) covers major infrastructure projects
- California: Pioneered the approach with concrete now included
- Colorado, New York, New Jersey: Active or pending legislation
- GSA: Requires EPDs for many building materials on federal projects
How Buy Clean Affects Precast Manufacturers
The implications for precast producers are significant and growing:
1. EPD Requirements
Most Buy Clean policies require products to have valid EPDs to be eligible for government projects. Without an EPD, your products may be automatically disqualified regardless of price or quality.
2. GWP Thresholds
Some policies set maximum Global Warming Potential limits. Products exceeding these thresholds are ineligible. As policies mature, these thresholds are expected to tighten, rewarding manufacturers who invest in lower-carbon production.
3. Reporting Requirements
Documentation requirements include EPDs, material sourcing information, and sometimes production data. This reporting burden can be substantial without proper systems in place.
| State/Program | EPD Required | GWP Limits | Status |
|---|---|---|---|
| California | Yes | Yes (phased) | Active |
| Federal (GSA) | Yes | Coming | Active |
| Colorado | Yes | Yes | Active |
| New York | Yes | Proposed | Pending |
Understanding EPDs for Buy Clean Compliance
Environmental Product Declarations are the foundation of Buy Clean compliance. These standardized documents, governed by ISO 14025, provide verified environmental impact data across a product's life cycle.
Types of EPDs
Industry-Wide EPDs
Based on industry average data, these EPDs are easier to obtain but represent generic products rather than your specific manufacturing.
- + Lower cost and faster to obtain
- + Good starting point for compliance
- - May not reflect your actual performance
- - Less competitive advantage
Product-Specific EPDs
Based on your actual production data, these EPDs accurately represent your products' environmental performance.
- + Reflects actual performance
- + Competitive advantage if better than average
- + Required for premium LEED credits
- - Requires detailed production data
Preparing Your Plant for Buy Clean
Manufacturers who prepare now will be positioned to capture government project opportunities as these policies expand:
Buy Clean Readiness Checklist
- Obtain EPDs: Start with industry-wide EPDs if needed, plan for product-specific
- Track Production Data: Capture energy usage, material quantities, and mix designs
- Document Material Sources: Maintain supplier certifications and environmental data
- Evaluate Mix Designs: Identify opportunities to reduce embodied carbon
- Build Reporting Capability: Systems for generating compliance documentation
Strategies for Reducing Embodied Carbon
Meeting tightening GWP thresholds requires proactive steps to reduce the carbon footprint of your products:
Cement Optimization
Cement is typically the largest contributor to concrete's carbon footprint. Strategies include supplementary cementitious materials (SCite fly ash, slag), optimized mix designs, and low-carbon cement alternatives.
Energy Efficiency
Production energy contributes to embodied carbon. Efficient curing systems, optimized batch processes, and renewable energy can reduce this component.
Local Sourcing
Transportation of materials affects total carbon footprint. Sourcing aggregates and other materials locally can reduce overall GWP.
Waste Reduction
Minimizing scrap and rework reduces the carbon intensity per unit of finished product. Quality systems that prevent defects have environmental benefits too.
The Competitive Advantage
While Buy Clean requirements create compliance obligations, they also create competitive opportunities for prepared manufacturers:
- Market Access: Be eligible for government projects competitors can't bid
- Premium Positioning: Low-carbon products can command better margins
- Customer Loyalty: Help customers achieve their sustainability goals
- Future-Proofing: Get ahead of regulations before they tighten
- Operational Efficiency: Carbon reduction often aligns with cost reduction
The Timeline is Now
Don't wait for Buy Clean to come to your market. EPDs can take 3-6 months to obtain, and production systems need time to implement. Manufacturers who start now will be ready when requirements expand to their region.
Conclusion: Sustainability as Strategy
Buy Clean legislation represents a fundamental shift in how construction materials are procured. For precast manufacturers, this shift creates both challenges and opportunities.
The manufacturers who view EPDs and carbon reduction as strategic investments rather than compliance costs will capture growing market share as these policies expand. Those who wait may find themselves locked out of significant project opportunities.
