How Can Real Estate Investment Trusts (REITs) Adapt to the Shift Towards Green Buildings in the UK?

April 21, 2024

As the world grapples with the implications of climate change, the property market is experiencing a significant shift. A rising tide of sustainable property investments is transforming the landscape of the sector, driven by increasing consumer demand and stringent government regulations. In this evolving landscape, real estate investment trusts (REITs) find themselves at a critical juncture. The big question is: how can they adapt and thrive in the new era of green buildings?

The Role of REITs in the Property Market

REITs play an integral role in the property market. They allow investors to own income-producing real estate without having to buy and manage properties themselves. However, the traditional focus of these trusts has been on maximising property values and rental income, not necessarily on sustainability.

As a result, REITs are now grappling with the reality of a new property market where green credentials are becoming increasingly crucial. A key factor in this shift is the growing importance of Environmental, Social, and Governance (ESG) factors in investment decisions. Investors are increasingly looking for assets that align with their sustainable objectives, and properties that don’t meet these criteria can face a higher risk of depreciation.

The Shift Towards Green Buildings

Green buildings, also known as sustainable or high-performance buildings, are designed to reduce or eliminate negative impacts on the environment and climate. These structures are energy-efficient, resource-efficient, and environmentally responsible. They are rapidly becoming the new standard in property investment.

This shift towards green buildings is driven by multiple factors, including growing investor demand for sustainable assets, stricter building regulations, and the need to mitigate risks associated with climate change. The trend has led to a situation where REITs that are slow to adapt could find their assets underperforming in the market.

Green Buildings as a Viable Investment

For REITs, the transition to green buildings might seem daunting, especially considering the potential costs of retrofitting existing properties. However, it’s important to understand that green buildings are not just a trend or a regulatory requirement – they can also be a highly viable investment.

Properties with green credentials have a number of advantages over traditional buildings. They can command higher rents and sales prices, have fewer vacancies, and are less likely to become obsolete. Additionally, green buildings can help REITs attract investors who are increasingly focused on sustainability. By investing in green buildings, REITs can reduce their risk exposure, future-proof their portfolios, and potentially enhance their returns.

Strategies for REITs to Adapt to the Green Building Shift

Adapting to the shift towards green buildings requires a proactive approach from REITs. They can start by conducting a comprehensive assessment of their existing properties. This involves evaluating the environmental performance of each asset, identifying areas of improvement, and determining the cost and feasibility of making these improvements.

REITs can also consider incorporating green features into new properties. This can involve using sustainable building materials, incorporating energy-efficient systems, and designing properties to maximise natural light and ventilation.

Finally, it’s important for REITs to communicate their sustainability efforts to their investors. This could involve regularly reporting on their ESG performance, setting clear sustainability targets, and demonstrating how they are working towards these goals.

The Future of Green Buildings and REITs

As the shift towards green buildings continues to gain momentum, REITs that can adapt and thrive in this new landscape will be well-positioned for success. In this context, green buildings are not just a response to climate change and regulatory pressures, but an opportunity for REITs to enhance their performance and attract sustainable investors.

As the property market continues to evolve, it’s clear that green buildings are here to stay. For REITs, the key to success lies in recognising this shift and taking actionable steps to adapt. By doing so, they can ensure their portfolios remain competitive, resilient, and attractive to a growing pool of sustainable investors.

Utilising Green Bonds and Energy Star Certification

Shifting to green buildings necessitates significant initial investment. To facilitate this, real estate investment trusts (REITs) could consider issuing green bonds. These are fixed-income securities designed specifically to fund projects with environmental benefits. By issuing green bonds, REITs can attract investment capital from a growing pool of sustainable investors, while also funding their transition towards green buildings.

Another strategy is for REITs to pursue Energy Star certification for their properties. Energy Star is a U.S program helping businesses and individuals save money and protect our climate through superior energy efficiency. Certified buildings are verified to perform better in terms of energy efficiency compared to their peers. They use less energy, are less expensive to operate, and cause fewer greenhouse gas emissions. Given these benefits, properties with Energy Star certification can command higher rents and have lower operating expenses, boosting the cash flow and profitability of REITs.

In a case study, Boston Properties, a self-administered and self-managed real estate investment trust (REIT), has been successful in incorporating sustainable practices in their asset management. They have a portfolio of Energy Star certified buildings and have also used green bonds to finance their sustainability initiatives.

The Role of Sustainable Building Practices in the Real Estate Sector

While the initial transition to green buildings might involve significant expenditure, the long-term benefits of sustainable building practices in the real estate sector are substantial. Green buildings have a lower total lifecycle cost compared to traditional buildings. They are less expensive to operate due to their energy efficiency, and they have lower maintenance costs.

Sustainable buildings can also contribute to healthier and more productive workplaces. They incorporate design elements that enhance natural light, improve air quality, and promote better occupant comfort and well-being. These factors can increase tenant satisfaction and retention, thereby enhancing the revenue and cash flow of REITs.

Moreover, sustainable buildings are less likely to become obsolete. As the world grapples with climate change and as building regulations become increasingly stringent, properties that are not eco-friendly may risk becoming unattractive to tenants and investors. By investing in sustainable buildings, REITs can future-proof their portfolios and ensure their longevity in the market.


The shift towards green buildings in the UK presents both a challenge and an opportunity for REITs. On one hand, they must grapple with the reality of a changing property investment landscape, where sustainability is no longer a ‘nice-to-have’ but a necessity. On the other hand, this shift offers a chance for REITs to differentiate themselves, attract a growing pool of sustainable investors, and enhance the resilience and competitiveness of their portfolios.

Moving forward, the success of REITs will depend on their willingness and ability to adapt to this new landscape. By incorporating green building practices, pursuing energy efficiency, utilising financial instruments such as green bonds, and communicating their sustainability efforts to investors, REITs can ensure they remain at the forefront of the real estate sector. Embracing green buildings is not just about compliance or risk mitigation – it’s about seizing an opportunity for growth and value creation in an increasingly sustainable world.
