Net Zero
ULI Philadelphia and the ULI Net Zero Imperative, in partnership with the City of Philadelphia’s Division of Housing and Community Development and the Philadelphia Housing Development Corporation, hosted a two-day technical assistance workshop in May 2025, focused on retrofitting existing affordable housing to net zero.
In 2022, Philadelphia-based development firm Post Brothers bought two office buildings on Connecticut Avenue in Washington, D.C., with plans to convert them into approximately 530 residential units. Despite the site’s proximity to Dupont Circle and a coveted residential area, assembling a viable capital stack proved more challenging than anticipated. Ultimately, a $465 million Commercial Property Assessed Clean Energy loan from Nuveen Green Capital in December of 2025—billed as the largest ever originated under the program—made the conversion possible.
FORUM, a life sciences building developed by Lendlease, is the first purpose-built life sciences building in Boston Landing, a mixed-use district in the city’s Allston-Brighton neighborhood. Targeting LEED Platinum, the recently opened building employs numerous strategies that enable companies to meet stringent regulatory requirements, reduce their carbon footprint, and achieve net zero operations.
In late 2025, the ULI Randall Lewis Center for Sustainability in Real Estate convened a series of roundtables with sustainability leaders to explore the industry’s perspective on top global priorities in 2026. Roundtables consisted of members of the ULI Americas Sustainable Development Council, the ULI Asia Pacific Net Zero Council, the ULI Europe Sustainability Council, and sustainability-oriented committees of District Councils from ULI San Francisco, ULI New York, ULI Los Angeles, ULI Singapore, and ULI Philadelphia.
Since Microsoft established its headquarters in Redmond, Washington, in 1986, the company’s campus has grown from four buildings to more than 100. The East Campus Modernization Project is the latest addition: replacing several older structures with ones designed to meet the demands of the modern hybrid workplace—and embody the company’s commitment to both employee well-being and environmental stewardship.
Within the next 50 years, Earth will become a planet of cities. From São Paulo to Shanghai, Lagos to Los Angeles, today’s cities are no longer just places where people live. They are the active ingredient shaping how humanity evolves, how we work, how we connect, and how long we may ultimately thrive as a species. Arguably, few organizations are better positioned to contend with the challenges of a fast-urbanizing world than ULI.
With society and the real estate industry significantly behind on achieving the targets set in the Paris Agreement, and worsening affordability in Europe’s housing, ULI Europe’s C Change for Housing program has launched a landmark interactive systems map and companion report to help the real estate industry identify, co-create, and scale the solutions needed to decarbonize existing and future affordable housing.
The ongoing challenges in decarbonizing skyscrapers, warehouses, apartments, and myriad other types of buildings were a key topic during ULI’s 3rd Real Estate Developer & Utility Convening on September 22—part of Climate Week NYC, the largest climate conference outside of the United Nations’ COP.
ULI’s Global Sustainability Outlook, launched in 2021 by the Randall Lewis Center, has become the organization’s annual barometer on the sustainability topics shaping real estate and land use. Each year, the report distills insights from global industry leaders to identify the top issues most likely to influence strategic decision-making in the year ahead and beyond.

Given the pressing challenges facing real estate globally on advancing building decarbonization, ULI is honored to announce the eight District and National Councils selected to participate in the fifth Net Zero Imperative (NZI) Cohort, joining nearly 30 global communities that have engaged with the program to date. NZI is a multiyear initiative to accelerate decarbonization in the built environment and is a significant aspect of ULI’s work to advance its net zero mission priority.
The ULI Net Zero Imperative (NZI) is ULI’s multiyear initiative to accelerate decarbonization in the built environment and advance the organization’s net zero mission priority. Implemented by the ULI Lewis Center for Sustainability in Real Estate, key programs include Technical Assistance Panels (TAPs), which are intense three-day engagements during which a panel of ULI member experts and partners help clients or sponsors, often local governments, think through strategies for advancing their net zero goals.
ULI has launched C Change for Housing, a major new pan-European program designed to mobilize the real estate industry around two of society’s most urgent and interconnected challenges: the climate crisis and housing affordability.
The United States had record-breaking renewable energy growth in 2024, with renewables—including wind, solar, geothermal, and hydropower—and battery storage making up 30 percent of the country’s large-scale power-generating capacity. Real estate is on board, positioned to confront some of the challenges facing clean energy in the U.S., especially as electricity demand is predicted to soar during the next five years.
Operationalizing ULI’s Net Zero Mission Priority
Phase 2 of the Willets Point redevelopment project is transforming an industrial part of Queens that once-inspired F. Scott Fitzgerald’s “valley of ashes” in The Great Gatsby in 1925. A century later, Queens Development Group—a joint venture between Related Companies, Sterling Equities, and New York City Football Club—is converting 23 acres (9.3 ha) of underutilized land into a $3 billion mixed-use community.
In January 2025, the Holcim Foundation played host to a second Global Fellowship—this time for Latin America—in Mexico City. The immersive two-week program occurred in collaboration with UNAM (National Autonomous University of Mexico) and focused on sustainable construction rooted in the social, environmental, and political realities of the region. The Fellowship is part of the Holcim Foundation’s global initiatives to support next-generation practitioners in the built environment.
This year, global ULI Greenprint real estate members reported a 6.3 percent year-for-year, like-for-like reduction in absolute carbon emissions. This result marks the second year in a row that members have reported a reduction of more than 6 percent in absolute carbon emissions—a testament to ULI Greenprint members’ leadership in making progress on their sustainability goals. In addition to leading by example, members continue to fund ULI resources that support the broader industry’s decarbonization progress.
ULI’s Randall Lewis Center for Sustainability in Real Estate held roundtable discussions with members of the ULI Americas Sustainable Development Council, the ULI Asia Pacific Net Zero Council, and the ULI Europe Sustainability Council to inform an outlook for 2025. During the discussions, members addressed sustainability topics and issues that are on the rise, why they matter, and what actions the industry should pursue in the future. Based on expert knowledge shared by those who attended, ULI identified five issues that will shape real estate decision-making in the coming months.
Climate considerations have increasingly become a critical focus for real estate owners, operators, and investors over the past few decades, particularly as the frequency of billion-dollar weather and climate disasters has surged. Beyond the headline-grabbing events, more frequent temperature extremes and less stable energy costs have real financial implications for owners and residents. Key changes in our operating environment include:
Increasingly, such disasters as storms, wildfires, pandemics, and flooding are spurring cities across the United States to prioritize resiliency. Coastal communities throughout Florida know the urgency firsthand. From the Gulf of Mexico to the Atlantic Ocean, many Florida communities were isolated in 2024 when hurricanes and other weather-related events closed roads and cut off power. Our most vulnerable populations took an especially hard hit. Planners, academics, and community members are rethinking how to elevate their response and help communities become more resilient. Could one answer be on four wheels and a chassis?
Governments, businesses, and communities need to collaborate to reduce carbon emissions to ensure that decarbonisation is not just a buzzword.
A new initiative aimed at promoting low-carbon steel in China’s real estate sector has been launched, co-convened by ULI Greenprint, the World Steel Association, and the China Iron and Steel Association. This collaboration unites major real estate developers and steel manufacturers to drive the transition to low-carbon steel production, with the goal of significantly reducing emissions in Mainland China and Hong Kong. China’s steel industry plays a pivotal role in global efforts to combat climate change.
Against the iconic backdrop of Hong Kong’s skyline, a room filled with cross-disciplinary real estate experts engaged in a lively display of unprecedented collaboration. Brightly colored sticky notes plastered across the floor-to-ceiling windows mapped out an intricate web of relationships between developers, tech providers, facility managers, investors, utilities, and more. The pioneering systems change workshop was piloted by ULI APAC Greenprint and aimed to address a critical challenge: how to accelerate climate tech implementations that will lead to long-term sustainability.
According to the second annual C Change Survey, 93 percent of respondents report incorporating transition risks into their real estate investment decisions, indicating the industry’s growing awareness and commitment to integrate climate-related financial risks into decision-making processes.
Given the pressing challenges real estate is facing globally on advancing building decarbonization, ULI is honored to announce that 10 District and National Councils have been selected to participate in the fourth Net Zero Imperative (NZI) Cohort. NZI is a multiyear initiative to accelerate decarbonization in the built environment and is a significant aspect of ULI’s work to advance its net zero mission priority.
Hundreds of events are scheduled September 22-27 for Climate Week NYC 2024, an annual event that drives climate action by those at the very top of business and politics, but also by communities, artists, and activists. This year’s theme: It’s Time. The built environment is a part of the dialogue, as are cross-sector issues like circular economy, water, finance, biodiversity, adaptation, health, environmental justice, policy, and more. With more than 600 events to choose from, it’s easy to assemble a perfect, customized itinerary for the week.
For new construction, owners, developers, and investors can achieve the best low-carbon results by considering both the embodied and operational carbon impacts of their buildings and striking a balance between upfront carbon in materials and long-term efficiency returns, according to a new study by ULI. The report examines the various tradeoffs presented when these two types of carbon are considered in the design of a building’s façade and envelope.
