Since the AIA 2030 Commitment launched in 2009, the program has become the architecture profession’s primary scale of progress for reducing the built environment’s carbon emissions.
The Commitment began by creating a shared framework for measuring the energy performance of design projects at the portfolio scale. Over the past 15 years, that framework has done its job. Over 1,400 signatory firms have now signed on and begun building cultures of measurement, developing internal accountability systems, and driving meaningful gains in energy efficiency across tens of thousands of projects.
The Design Data Exchange (DDx) is making an impact. The program's longitudinal dataset, now encompassing well over 50,000 reported design projects, stands as AIA’s primary climate action program and one of the profession's most valuable strategic assets. As we approach 2030, the AIA 2030 Commitment Working Group feels it is time to reflect on what the Commitment has taught us to date, and to evolve the program to reflect the changes we seek for the profession going forward.
We cannot “efficiency” our way to zero. The multi-year plateau in predicted Energy Use Intensity (pEUI) reduction is not necessarily a sign of stagnation. Firms have pushed energy efficiency toward a practical point of diminishing return, and that achievement deserves recognition. Rather, the plateau is a signal that energy efficiency alone can no longer serve as the 2030 Commitment’s sole proxy for progress toward zero emissions. And that continued efforts are needed on the policy front to improve regional building codes.
A lower pEUI does not always equal lower emissions. A gas-fired building and an all-electric building with identical pEUIs will appear equivalent in our current reporting framework. In reality, these two buildings represent fundamentally different emission trajectories. The gas-fired building is “locked-in” to fossil fuel emissions as long as the building’s systems rely on gas, while the all-electric building will follow the grid as it greens, getting closer to zero emissions as the grid becomes cleaner.
It is time to move toward total carbon reporting. As we move beyond the year 2030, the Working Group recommends repositioning the program to capture the full scope of decarbonization efforts across the built environment.
While these changes will not take effect for Reporting Year 2026, we will begin preparing for future reporting cycles with iterative changes in the coming year. In addition to changing the name of the Commitment itself, the recommendations are:
-
Maintaining a focus on energy efficiency and pEUI. The commitment must continue to benchmark pEUI as a primary gauge of energy efficiency and a critical guardrail to ensure that demand reduction remains central to our design practice.
-
Strongly encouraging and incentivizing energy modeling and fuel source reporting to enable total carbon metrics. Doing so will help progress toward making electrification visible and trackable at scale. More importantly, it means beginning the transition toward tracking the total carbon intensity of our portfolios. Total carbon involves calculating and reporting operational emissions using regional grid data, so that the combined contributions of energy efficiency, electrification, renewable energy, and grid decarbonization are all reflected in how we measure progress. This will include surfacing grid-mix data that already exists within the DDx. An emissions-centric lens will not replace pEUI; it will complete it, providing firms with a measurement framework that aligns with their commitment.
-
Expanding embodied carbon reporting. As a key part of the total carbon equation, expansion will allow signatory firms to capture carbon reductions beyond energy and operational emissions. While the DDx already tracks embodied carbon for building structures and enclosures; recent changes have expanded tracking by including the site, interiors, mechanical systems, and construction activity.
-
Realigning baselines and adding specificity. This will update existing baselines to more accurately reflect current building performance and ensure that firms can use the DDx as a goal-setting tool for active projects, rather than simply a repository of past data.
The year 2030 has always been a waypoint, not a finish line. The deeper objective of advancing carbon neutral buildings remains as urgent as ever. The AIA 2030 Commitment By the Numbers report and Architecture 2030's 2030 Beyond the Numbers report, grounded in the lived experience of practitioners across the profession, confirm that the strategies needed to drastically reduce carbon emissions are not theoretical; they are already in practice. Every signatory firm deserves the tools, metrics, and professional community it needs to carry out its work through 2030—and beyond!
