Report Reveals Sustainable Snapshot
of American Architecture

A new report, the “U.S. Sustainable Design Report”[2] from Metropolis and Interface, provides a sustainable snapshot for U.S. architecture and design in 2025 and 2026. The report outlines perspectives on the industry at large, the perspectives that support it, and the specification data that outlines a realistic picture of sustainable architectural products.

It is an architectural responsibility to understand the environmental impacts of contributing to the built environment, which accounts for 42 percent of global carbon emissions. Understanding the industry’s mindsets, challenges, and strengths better equips architects with the knowledge they need to promote progress.

Estimations informing a sustainable snapshot

A strong point of emphasis in the report is the lack of a universal, recent, and credible metric for evaluating sustainability in the American built environment; a compiled certification-tracking database does not yet exist.

Jaxson Stone explains that adding up the reported square footage certified across LEED, WELL Standard, Green Globes, and Living Future projects accounts for less than three percent of American building square footage. However, this compilation does not account for an overlap in certifications.

The data, derived from each certifying organization’s self-publicized numbers, shows the amount of certified space in the American built environment:

• Nearly 771.1 million m² (8.3 billion sf) is LEED Certified.
• More than 74.3 million m² (800 million sf) is WELL Certified.
• Nearly 69.7 million m² (750 million sf) is Green Globes Certified.
• 278,709 m² (3 million sf) is Living Future Certified.

It is also important to note that a large proportion of buildings were constructed before many current standards were put into place, and more often than not, it is a more sustainable choice not to rebuild or renovate pre-existing functional structures, barring health and safety risks or significant energy inefficiency.

Regardless, the proportion of buildings that can be classified as sustainable across the U.S. is undeniably small. Certification numbers, however, do not necessarily reflect the number of green designs; given the guidelines, they may often be followed without clients wanting to pay for certification.

Increasing uncertainty in AI for sustainability

Between 2024 and 2025, confidence in both AI’s capabilities for industry enhancement and in the company’s decision-making surrounding AI has dropped by nine percent. At the same time, 13 percentage points more design leaders report AI is the top sustainability enabler.

Impacts across the industry

In METROPOLIS’s 2025 Sustainable Design Survey, 400 industry professionals spanning broad company types, firm sizes, roles, and age ranges, with the largest proportion of respondents, 41 percent, aged 30-45. Respondents reported varying levels of influence on project sustainable outcomes, with the largest proportion, 35 percent, reporting moderate influence, and only one percent reporting no influence. Sixty-four percent note that sustainability considerations often or almost always impact project decisions, and 67 percent report being comfortable or very comfortable applying sustainable principles in daily work. This data offers a positive environmental outlook on the mindsets, abilities, and knowledge guiding today’s designs.

For architects, sustainability can only go as far as the client wishes. In fact, respondents attribute the greatest improvement in design sustainability to client education and demand. Making sustainability information available to clients on all accounts, from large-scale developers to small-scale homeowners, drives sustainable designs. As a joint effort across the built environment, making information public and easily accessible helps building owners better understand how sustainable designs or building specifications can benefit them long-term, whether it be cost-efficient operations, tax rebates, or a reduced need to replace or excessively maintain materials.

In terms of specifications, only 15 percent report rarely or almost never being able to incorporate sustainable materials into designs. This means the vast majority—85 percent—can specify sustainable materials, sometimes, often, or almost always.

Circularity is an increasingly prevalent buzzword across the design industry[3], essentially forming a zero-waste approach by maximizing the renewable lifespan of products and adapting them further into designs. Metal is an excellent example of this concept in practice; for example, aluminum railings are often made from recycled aluminum products, have a long lifespan, and are largely recyclable once their lifespan has come to an end.
