Find Optimism in Action - why policy is indispensable to meeting US embodied carbon targets

Climate work can feel heavy – especially right now. With the scale of change required, shifting influences, and mounting pressure, it’s easy to lose sight of where progress is happening. But momentum matters, and tangible actions that highlight climate solutions are essential to sustaining it. 

At CLF, we’re working to bring those opportunities to the forefront – showing how today’s solutions can meaningfully reduce embodied carbon and move the built environment towards a more climate-aligned future. 

A clear signal of that opportunity comes from The Embodied Carbon Pathways to 2050 for the United States, a collaborative report by CLF, RMI, and the UW Life Cycle Lab. This report offers the most comprehensive analysis to date on the future of US embodied carbon and how embodied carbon emissions could evolve, and be reduced, across US buildings and materials. Rapid decarbonization is essential to meet the emissions reductions required for a 1.5°C-aligned future. With limited time and mounting pushback, prioritizing the highest-impact strategies is critical, and this report identifies a broad set of existing and emerging solutions with immediate potential.

Our analysis shows that a combination of strategies — from material substitution and design optimization to electrification and carbon capture — is essential to achieving the necessary emissions reductions. It also shows that everyone in CLF’s network has a role to play: changes in manufacturing, design, and procurement, supported by private- and public-sector policies and incentives, are key to accelerating the transition to a lower-carbon construction sector. 

We hope this report helps you see embodied carbon reduction not as an abstract challenge, but as a set of concrete opportunities. Dive in, and identify one way these pathways can inform your work — whether you’re shaping policy, specifying materials, or influencing procurement decisions. Progress is already underway, and there’s a role for everyone in moving it forward.

Embodied Carbon Pathways to 2050 for the United States

Embodied Carbon Pathways to 2050 for the United States, a collaboration between the Carbon Leadership Forum (CLF), RMI, and the University of Washington (UW) Life Cycle Lab, provides an assessment of embodied carbon from US construction materials and explores pathways to align with a 1.5°C global warming limit.

This report serves as a call to action, urging the industrial and construction sectors to continue progress towards global targets.

The embodied carbon of key construction materials used in buildings and infrastructure in the United States is significant and requires deployment of a large range of strategies. While challenges remain, existing technologies and strategies can deliver meaningful reductions in the near term. Success will depend on rapid policy action, cross-sector collaboration, and sustained investment in both proven and emerging solutions.

This report was published in August 2025.

Perkins&Will recently published a three-part report - Executive Summary, Context, and Applications in Architecture, and State of the Industry Survey - that explores how regenerative natural materials can reduce carbon and reshape the way we design and construct buildings.
