Climate Migration and CRE: Preparing for Population Shifts and Their Impact on Property Values

The global climate is changing at an alarming rate, and the consequences are far-reaching. One of the most significant impacts is climate migration, a phenomenon that is reshaping demographics and presenting unique challenges for the commercial real estate (CRE) industry. As rising sea levels, extreme weather events, and prolonged droughts force people to relocate, the CRE sector must adapt to these population shifts and their impact on property values. This report delves into the intricate relationship between climate migration and CRE, providing valuable insights into how the industry can prepare for these changes and mitigate potential risks.

Understanding Climate Migration

Climate migration, the displacement of populations due to the adverse effects of climate change, is a complex issue with both immediate and long-term consequences. These effects can manifest as sudden-onset disasters, such as hurricanes and floods, or as gradual changes, such as sea-level rise and desertification¹. While climate change affects everyone, its impact is not uniform. Vulnerable populations, often those with limited resources and pre-existing socioeconomic challenges, are disproportionately affected, exacerbating existing inequalities and forcing them to seek safer and more sustainable living conditions¹.

It is important to note that while climate change can be a significant driver of migration, it is often intertwined with other factors, such as economic opportunities and social networks². Understanding this complexity is crucial for CRE professionals as they assess the potential impacts of climate migration on specific regions and property markets.

While many associate climate migration with permanent relocation, it is essential to recognize that most disaster-related displacements are temporary³. Following a natural disaster, many individuals return to their homes once the immediate danger has subsided. However, the increasing frequency and severity of extreme weather events, coupled with gradual environmental changes, suggest that climate-related migration may become more permanent and large-scale in the future³.

Impact on Population Shifts

Climate migration is already reshaping population demographics across the globe. Projections indicate a potential displacement of 140 million people by 2050 due to climate change⁴. However, this figure represents just one estimate within a broader range of possibilities. Some studies suggest that up to 3 billion people could be living outside the "human climate niche" by the end of the century, highlighting the significant uncertainty surrounding the scale of future climate migration⁴.

In the United States, internal migration patterns are shifting as people move from climate-vulnerable regions to more resilient areas⁵. Demographic-driven demand plays a crucial role in shaping these trends, with factors such as population growth, age distribution, and household formation influencing housing needs and preferences⁶.

Cities in the South and West, particularly in Texas, Florida, and Arizona, are experiencing rapid population growth, driven in part by climate migration⁷. This influx of new residents presents both opportunities and challenges for receiving communities. While population growth can stimulate economic activity and increase demand for housing, it can also strain existing infrastructure, resources, and social services⁸.

One notable example is the impact of Hurricane Katrina in 2005, which led to a significant influx of climate migrants from New Orleans to Houston, Texas. This sudden increase in population placed considerable pressure on Houston's housing market, highlighting the need for affordable housing options and proactive planning to accommodate climate migrants⁹.

Furthermore, the impact of climate change on rural agricultural communities in South Asia and sub-Saharan Africa is driving migration towards urban centers¹⁰. This trend underscores the global nature of climate migration and its potential to reshape urban landscapes and strain resources in receiving cities.

Effects on Property Values

The impact of climate migration on property values is complex and multifaceted. While increased demand in receiving areas can drive up property values¹¹ the long-term effects of climate change on real estate markets remain uncertain.

Properties in areas highly vulnerable to climate risks, such as coastal regions prone to flooding or wildfire-prone areas, may experience a decline in value as people become more aware of the potential for damage and increased insurance costs¹². Climate change can also lead to costly repairs, rising insurance premiums, and market devaluation, further complicating property value assessments¹⁴.

On the other hand, climate risk factors can also have a net-positive effect on property value in some markets. Properties with features that enhance climate resilience, such as those located in areas with lower risk of extreme weather events or those with energy-efficient designs, may experience a capital value premium of up to 20%¹⁵.

Regional Variations in Property Value Impacts

The impact of climate migration on property values can vary significantly across different regions. Analyzing regional trends and local market dynamics is crucial for CRE investors to make informed decisions.

The following table provides a snapshot of population growth and home price changes in various U.S. cities:

¹⁶

This data illustrates the diverse impacts of population growth on property values. While some cities, such as Port St. Lucie and Palm Bay in Florida, experienced both population growth and home price increases, others, like Goodyear and Buckeye in Arizona, saw population growth accompanied by declining home prices. These variations highlight the importance of considering local market conditions, climate risks, and economic factors when assessing property value trends.

How the CRE Industry is Preparing

The CRE industry is beginning to recognize the significance of climate migration and its potential impact on the market. Several strategies are emerging as the industry adapts to these changes:

• Investing in Climate-Resilient Infrastructure: Developers are increasingly incorporating climate-resilient features into new buildings to protect them from extreme weather events and enhance their long-term value. This includes incorporating features such as elevated foundations to mitigate flood risk¹⁷ using fire-resistant materials in wildfire-prone areas¹⁸ and implementing energy-efficient systems to reduce reliance on fossil fuels and minimize operational costs¹⁹.
• Assessing Climate Risk: CRE investors are conducting more thorough risk assessments, considering the potential impact of climate change on property values and investment returns²⁰. This involves evaluating the vulnerability of properties to specific climate hazards, such as flooding, extreme heat, and wildfires, and incorporating these risks into investment decisions. By understanding the potential financial implications of climate change, investors can make more informed choices and prioritize properties with greater resilience.
• Promoting Sustainable Practices: The industry is embracing sustainable building practices to reduce its environmental footprint and meet the growing demand for eco-friendly properties²¹. This includes using sustainable building materials²² implementing energy-efficient designs¹⁹ and incorporating green building certifications, such as LEED, into development projects. These practices not only contribute to climate change mitigation but also enhance property value and attract environmentally conscious tenants.

It is important to acknowledge that the built environment itself has a significant impact on climate change²³. The CRE industry must take responsibility for reducing its carbon emissions and promoting sustainable land use practices. This includes minimizing embodied carbon in building materials²¹ investing in renewable energy sources¹⁹ and prioritizing green infrastructure in development projects.

Government Initiatives and Policies

Governments at all levels are playing a crucial role in addressing climate migration and its impact on real estate. Several initiatives and policies are being implemented to support climate adaptation and resilience:

• Zoning Reforms: Local governments are implementing zoning reforms to encourage denser housing development and increase affordability, particularly in receiving communities experiencing population growth due to climate migration²⁴. This includes allowing for multi-family homes in more neighborhoods, encouraging transit-oriented development, and reducing barriers for construction permitting.
• Financial Incentives: State and federal governments are providing financial incentives for climate adaptation projects, including funding for resilient infrastructure and housing development²⁴. This includes grants, tax breaks, and subsidies to support the construction of climate-resilient buildings and infrastructure, as well as programs to assist vulnerable populations in relocating from high-risk areas.
• Managed Retreat: In some cases, governments are pursuing managed retreat strategies, offering buyouts to homeowners in high-risk areas to facilitate relocation²⁶. This approach recognizes that some areas may become uninhabitable due to climate change and aims to provide a pathway for residents to move to safer locations.
• International Cooperation: Recognizing the global nature of climate migration, governments are engaging in international cooperation to address the challenges and support vulnerable countries²⁷. This includes sharing best practices, providing financial assistance, and developing policies to protect the rights of climate migrants.

Investment Strategies and Risk Management

CRE investors are adapting their strategies to account for climate migration and its associated risks:

• Diversification: Diversifying investments across different regions and property types can help mitigate the risk of climate-related losses²⁸. By spreading investments across a variety of locations and asset classes, investors can reduce their exposure to specific climate hazards and market fluctuations.
• Climate Risk Assessment: Incorporating climate risk assessments into investment decisions is crucial for identifying vulnerable properties and making informed choices²⁰. This involves using climate modeling tools, analyzing historical data, and considering future projections to assess the potential impact of climate change on property values and investment returns.
• Resilience Planning: Investing in climate-resilient infrastructure and adaptation measures can protect properties and enhance their value¹⁸. This includes incorporating flood-proofing measures¹⁸ using fire-resistant materials¹⁸ and implementing energy-efficient designs¹⁸.
• Collaboration and Engagement: Engaging with local communities, governments, and other stakeholders is essential for understanding climate risks and developing effective adaptation strategies¹⁸. This includes participating in community planning processes, collaborating with local organizations, and advocating for policies that support climate resilience.

Conclusion
