What is Buy Clean and how does it affect concrete producers?

Buy Clean: What Concrete Producers Need to Know

What Is Buy Clean?

Buy Clean is a policy framework — adopted at the state, local, and federal level in the United States — that requires construction materials used in publicly funded projects to meet maximum Global Warming Potential (GWP) thresholds. Concrete is one of the primary materials covered.

How Buy Clean Requirements Work

Project specifications under Buy Clean policies require concrete suppliers to provide verified EPDs demonstrating that their mixes meet the applicable GWP limit for the project. The requirements typically apply to specific material categories (e.g., ready-mix concrete) and define a maximum kg CO₂e per cubic yard or cubic meter based on a regional or national benchmark.

Where Buy Clean Is Active

California has the most developed Buy Clean program and has influenced similar policies in other states. Federal Buy Clean guidance has also been issued, with more states expected to adopt requirements in the coming years.

How Climate Earth Helps

Climate Earth generates Buy Clean-compliant EPDs automatically and tracks project mixes against applicable GWP benchmarks. Your sales and technical teams can respond to Buy Clean requirements immediately with verified, project-specific data.
