CMG Principal Consultant Lori Ferriss, AIA, PE, LEED AP BD+C, recently shared her perspective on the evolving role of the built environment in global climate action in an article for Architect Magazine, “Building Momentum: 5 Takeaways from COP30.”
Drawing on her involvement in global built environment climate initiatives, Lori examines what emerged from COP30 in Belém, Brazil—and, importantly, what those developments mean for architects and other professionals shaping the built environment.
The stakes are significant. Buildings and construction are responsible for up to 42% of global greenhouse gas emissions, making the built environment both a major contributor to climate change and one of the most consequential opportunities for addressing it. Yet, as Lori observes, buildings remain underrepresented in many of the formal agreements shaping international climate policy.
Climate action is moving beyond negotiation
One of the most important developments Lori identifies is a growing shift from setting goals toward implementing solutions that already exist.
While COP30’s formal negotiations produced mixed results, initiatives outside the negotiating room demonstrated increasing coordination and momentum. The COP30 Action Agenda, for example, is intended to organize and track climate solutions across sectors, including approaches involving buildings, communities, culture, and heritage. New implementation plans also create mechanisms for advancing and measuring progress in areas including net-zero resilient buildings and heritage-informed decarbonization.
At the governmental level, the newly established Intergovernmental Council on Buildings and Climate represents another important step. Its inaugural meeting brought countries together specifically around decarbonizing and strengthening the resilience of the built environment, including efforts to address the closely connected challenges of climate change and affordable housing.
For the AEC industry, these developments signal an important evolution: buildings are increasingly being recognized not simply as sources of emissions to be reduced, but as part of a broader system through which climate solutions can be implemented.
Resilience, culture, and communities are becoming part of the climate conversation
Lori also highlights an expanding definition of climate action.
Mitigation—reducing the emissions contributing to climate change—has long dominated the conversation. At COP30, adaptation and resilience received greater attention, including a commitment to substantially increase adaptation financing. Buildings and infrastructure will be central to how communities respond to changing climate conditions, particularly in areas already experiencing significant impacts.
At the same time, cultural heritage and community-centered approaches gained greater visibility. Lori sees this as an important development because successful climate action extends beyond technical performance. Existing buildings, cultural resources, local knowledge, and community priorities can all contribute to solutions that address carbon while also strengthening social, economic, and cultural resilience.
That broader perspective is central to Lori’s work. An architect, structural engineer, and recognized leader in sustainable stewardship of existing buildings, she brings together technical expertise, policy experience, and practice strategy to help firms understand how sustainability can become part of everyday decisions about projects, operations, leadership, and the future of their practices. Her industry leadership has included roles with the AIA Committee on the Environment, Climate Heritage Network, International Council on Monuments and Sites, and other organizations advancing built environment climate action.
What does this mean for design firms?
Perhaps the most important message from Lori’s analysis is that the opportunity for the building sector is not dependent on international negotiators solving the problem first.
The tools, knowledge, collaborations, and emerging policy structures needed to make meaningful progress are continuing to develop. For architects, engineers, contractors, and their clients, that creates both an opportunity and a responsibility to consider how climate mitigation, adaptation, resilience, reuse, and community impact become integrated into the way projects and practices operate.
For firm leaders, the conversation is increasingly strategic as well as technical: understanding where climate action is headed, determining where a firm can have meaningful impact, and translating broad commitments into priorities and processes that can be implemented consistently.
As Lori’s report from COP30 makes clear, the built environment has an increasingly important role to play in moving climate action from ambition to implementation.
