1. Introduction

In response to growing environmental concerns and the imperative for sustainable urban development, ecological finance has emerged as a strategic mechanism to drive environmentally responsible practices, particularly within real estate sectors in developing economies like Nigeria. Globally, the pursuit of sustainability has intensified, with ecological finance playing a central role in aligning economic activities with environmental preservation. The real estate industry, known for its substantial ecological footprint through land use, energy consumption and construction emissions, has been increasingly scrutinized regarding its role in environmental degradation. This underscores the urgency of structured and sustainable environmental management. In Nigeria, listed real estate institutions are under mounting pressure from stakeholders, regulators and international sustainability frameworks to adopt eco-friendly practices and contribute to climate-conscious urban development. This evolution necessitates innovative financial tools that can incentivize and support sustainable management approaches. Ecological finance instruments including ecological funds, ecological support, ecological rights and ecological interests have been identified as transformative pathways for realigning real estate development with environmental goals (Ogunyemi & Alade, 2023; Musa et al., 2024).

For instance, ecological funds, similar to green bonds globally, are increasingly used to finance infrastructure projects with verifiable environmental benefits. In Nigeria, their relevance is growing in areas such as energy-efficient housing, sustainable construction and green urban renewal (UNEP, 2023). Likewise, ecological support, provided through sustainability-oriented credit facilities, helps real estate firms invest in eco-technologies and low-emission construction practices. This aligns with Nigeria’s broader commitment to the Sustainable Development Goals (SDGs) and it’s Nationally Determined Contributions under the Paris Agreement (Adewunmi & Ibrahim, 2024). Furthermore, ecological rights, backed by favorable policy and investment frameworks, have opened avenues for channeling capital into responsible real estate development. Ecological interests, akin to climate risk insurance, have also gained prominence as instruments to buffer firms against environmental and climate-induced losses,

thus supporting long-term sectoral resilience and sustainability (Eze & Okafor, 2025). However, despite these advancements, empirical research examining how ecological finance influences sustainable environmental management in Nigeria’s listed real estate institutions remains scarce. Most prior studies either generalize the impact of environmental finance or focus on profitability and compliance without unpacking the sector-specific strategic mechanisms (Olowu et al., 2024). Additionally, the multidimensional structure of ecological finance has rarely been investigated comprehensively in the Nigerian context. This study, therefore, seeks to fill this critical gap by exploring how various elements of ecological finance influence sustainable environmental management in Nigeria’s listed real estate firms. Such understanding is pivotal not only to academic inquiry but also to effective policymaking, sustainable investment strategies and the future of green real estate transformation in emerging economies.

1.1 Statement of the Problem

Nigeria’s real estate sector has increasingly come under scrutiny for its contributions to environmental degradation, including high energy consumption, resource-intensive construction practices and urban sprawl. Although national and international policies advocate for sustainable urban development, the country’s financial architecture has yet to fully integrate mechanisms that support long-term environmental goals. Ecological finance, encompassing instruments like ecological funds, support, rights and interests, is posited as a key enabler of sustainable environmental management. However, its application within Nigeria’s listed real estate institutions remains underexplored (Ogunyemi & Alade, 2023; Musa et al., 2024). While developed economies have recorded significant progress in greening their real estate sectors through ecological financial instruments, Nigeria’s uptake is still evolving. Ecological funds have begun to support green buildings and infrastructure, but their effect on long-term environmental management strategies in Nigerian real estate firms is inadequately documented (UNEP, 2023). Similarly, ecological support mechanisms such as sustainability-linked loans have potential to enhance energy efficiency and low-carbon building technologies, yet little empirical evidence exists on their impact in Nigeria’s sectoral context (Adewunmi & Ibrahim, 2024).


Int J Engg Mgmt Res 2025;15(2)2
Hussaini I, et al. Ecological Finance and Sustainable Environmental Management

In addition, ecological rights, through strategic public-private partnerships and incentives, have shown global success in guiding investment toward environmentally responsible projects. However, their practical effect on planning and executing sustainable developments within Nigeria’s real estate space is unclear. Ecological interests, crucial for mitigating the financial impact of climate-related disruptions, are rarely integrated into environmental risk planning or sustainability policies at the firm level (Eze & Okafor, 2025). Current literature largely emphasizes financial performance or regulatory compliance without investigating how the full spectrum of ecological finance instruments influences strategic environmental management in real estate institutions. This research gap is particularly pressing given Nigeria’s urbanization trajectory and environmental vulnerability. Accordingly, this study seeks to assess how ecological funds, ecological support, ecological rights and ecological interests affect sustainable environmental management in Nigeria’s listed real estate institutions providing critical insights for policymakers, investors, scholars and industry leaders.

2.1 Conceptual Review

2.1.1 Concept of Ecological Fund

Ecological fund represents a financial mechanism used to mobilize resources for projects that yield environmental sustainability benefits, such as energy-efficient real estate, sustainable building infrastructure and low-emission urban development (Adekunle et al., 2024; Zhou & Martinez, 2023). As a subset of ecological finance, ecological funds are increasingly recognized as essential tools in the global transition toward environmentally resilient economies. In developed regions such as the European Union and the United States, ecological fund instruments play a vital role in financing climate-adaptive infrastructure through stringent environmental disclosure and accountability frameworks, like the EU’s updated Sustainable Finance Disclosure Regulation (SFDR) (European Commission, 2024). Conversely, in developing economies like Nigeria, particularly in the real estate sector, the uptake of ecological funds has remained minimal due to factors such as low investor awareness, regulatory bottlenecks,

and underdeveloped capital markets (Ojo & Bakare, 2024). Scholars have emphasized the untapped potential of ecological funds in enhancing environmental planning and attracting sustainable investments within Nigerian real estate institutions.

2.1.2 Concept of Ecological Support

Ecological support refers to financial incentives or loans extended by banks and financial institutions to promote environmentally conscious development, such as eco-certified real estate projects and low-carbon building practices (Chen & Yusuf, 2023; Bello & Oyebanji, 2024). This support mechanism is pivotal in driving resource-efficient urban development and integrating sustainability into commercial property financing. In countries like China and Germany, ecological support has been embedded within green banking policies to steer credit toward environmentally sustainable ventures (Liu et al., 2023). However, Nigeria's financial institutions have yet to fully embed ecological support into their credit evaluation systems, particularly within the real estate space. Challenges including the absence of sector-specific ecological loan frameworks, risk-aversion to innovative environmental solutions, and limited technical expertise continue to hinder progress (Abubakar & Nwachukwu, 2024). Strengthening ecological support in the Nigerian real estate industry could significantly boost climate-resilient construction, environmental stewardship, and long-term urban sustainability.

2.1.3 Concept of Ecological Right

Ecological right involves strategic financial commitments toward environmentally sustainable assets and projects, including green buildings, smart city infrastructure and climate-adaptive real estate ventures (Franco & Adeyemi, 2024; Gupta & Salisu, 2023). Globally, ecological right initiatives are championed as both ethical and economically beneficial investments that deliver long-term environmental and financial returns. In advanced markets like the UK and Scandinavia, real estate developers are increasingly aligning their investment portfolios with ecological values, supported by tax reliefs and carbon-offset incentives (Hemmings & Larsdotter, 2023). Empirical evidence suggests that firms incorporating ecological right strategies often experience enhanced corporate reputation and long-term shareholder value.


Int J Engg Mgmt Res 2025;15(2)3
Hussaini I, et al. Ecological Finance and Sustainable Environmental Management

However, in Nigeria, ecological rights remain underleveraged due to inadequate policy direction, investor skepticism, and a weak sustainable investment culture (Umeh & Ayinde, 2023). Promoting ecological rights within listed real estate institutions can bridge the financing gap for green infrastructure and elevate Nigeria’s position in the global sustainable development agenda.

2.1.4 Concept of Ecological Interest

Ecological interest encompasses insurance products and risk-mitigation instruments designed to cover environmental and climate-related damages particularly those associated with building safety, flooding, or urban pollution risks (Okeke & Zhang, 2024; Mustapha & Bello, 2023). These products serve as a safeguard for real estate developers and investors, ensuring financial resilience against environmental contingencies. In countries such as the United States and Japan, the ecological interest sector has evolved with tailored insurance packages that promote green-certified construction and offer premium discounts for sustainable buildings (Tanaka et al., 2023). In Nigeria, however, the ecological interest segment remains nascent. A combination of low awareness, fragmented policy support, and weak enforcement of environmental regulations have limited its deployment in the real estate industry (Ogundipe & Danladi, 2024). Enhancing ecological interest offerings can support sustainable urban development by providing a financial cushion against climate-induced risks and encouraging real estate actors to adopt greener operational models.

2.2 Empirical Review

2.2.1 Ecological Fund and Sustainable Environmental Management

A recent study by Zhang et al. (2024) investigated the influence of ecological funds on firms’ environmental strategies in the United States. The study examined data from companies listed on the New York Stock Exchange (NYSE) between 2018 and 2023. Utilizing panel data regression models that combined financial performance metrics and environmental indicators, the authors found that firms leveraging ecological funds demonstrated a marked increase in long-term sustainability projects and significant improvements in environmental performance. The impact was particularly notable in industries with high environmental externalities. Similarly, Fischer and Müller (2024) analyzed how ecological funds have supported sustainable

planning across Europe, focusing on real estate development in Germany and France. Drawing from a sample of 60 real estate firms between 2019 and 2024, they applied comparative analysis and observed a strong linkage between ecological fund utilization and a reduction in carbon emissions, alongside growing investments in energy-efficient infrastructure. These findings highlight the strategic role ecological funds play in aligning firm objectives with national and global sustainability targets.
H1: Ecological fund positively influences sustainable environmental management.

2.2.2 Ecological Support and Sustainable Environmental Management

Okoro and Eze (2024) evaluated the role of ecological support in promoting sustainable environmental management within the Nigerian financial sector, with a specific emphasis on real estate financing. Their study utilized data from 25 Nigerian banks between 2017 and 2023 and employed a difference-in-differences (DiD) analysis to assess the effect of ecological support on environmental project funding. Results indicated a significant increase in green architecture investments and reduced environmental degradation, especially in urban development zones. Meanwhile, Karanja and Mburu (2024) focused on the East African context, using structural equation modeling (SEM) to explore the impact of ecological support in Kenya’s real estate sector. Their study found that ecological support enabled financing for solar-powered buildings and improved urban waste management systems, enhancing sustainability in metropolitan housing schemes. These studies underscore the necessity for expanding ecological support mechanisms to finance environmentally responsible urban growth, particularly in emerging markets like Nigeria.
H2: Ecological support positively impacts sustainable environmental management.

2.2.3 Ecological Right and Sustainable Environmental Management

Wang et al. (2024) examined how ecological rights affect sustainable practices in the Chinese real estate sector. Using firm-level data from 2015 to 2023, they employed regression data from 2015 to 2023, they employed regression models and environmental impact assessments to evaluate the effects of ecological rights on emissions reduction and resource efficiency.


Int J Engg Mgmt Res 2025;15(2)4
Hussaini I, et al. Ecological Finance and Sustainable Environmental Management

Their findings showed that firms investing in ecological rights, particularly those adopting green construction technologies, achieved notable reductions in carbon emissions and complied more effectively with environmental standards. In the European context, Schroeder and van Dijk (2024) explored ecological rights in Germany and the Netherlands. By analyzing data from 2016 to 2023 across major construction and real estate firms, they found that ecological rights significantly boosted air quality improvements and energy optimization within real estate developments. The researchers concluded that ecological rights serve as a key driver for sustainable environmental management by enabling firms to integrate eco-friendly technologies into their operations, thus supporting the transition toward climate-resilient urban ecosystems.
H3: Ecological right positively influences sustainable environmental management.

2.2.4 Ecological Interest and Sustainable Environmental Management

Ibrahim and Yusuf (2025) studied the influence of ecological interest on corporate environmental behavior in Nigeria’s real estate industry. Drawing from data collected from 35 insurance firms offering ecological interest products between 2018 and 2024, the authors applied econometric techniques to examine the role of insurance-based environmental risk coverage. Their findings revealed that real estate firms with ecological interest policies were more likely to adopt sustainable building practices, mitigate environmental liabilities and integrate climate risk assessments into their project plans. In a related study, Lewis and Anderson (2024) assessed the function of ecological interest mechanisms in the U.S. property development sector. Using a national sample of real estate developers and insurance providers, they found that ecological interest arrangements encouraged companies to implement emission-reduction strategies and enhance waste reduction frameworks. These results affirm the growing relevance of ecological interest as a financial instrument for enhancing environmental risk preparedness and promoting sustainable property development.
H4: Ecological interest positively contributes to sustainable environmental management.

2.5 Theoretical Underpinning

This study is anchored in the Triple Bottom Line (TBL) Theory and supported by the Environmental Economics Theory to explore how ecological finance contributes to sustainable environmental management within Nigeria’s listed real estate institutions.

2.5.1 Triple Bottom Line (TBL) Theory

The Triple Bottom Line (TBL) framework, developed by John Elkington (1994), proposes a broader definition of business success that transcends mere financial gains. It emphasizes three interdependent dimensions: People (social equity), Planet (environmental integrity) and Profit (economic viability). TBL is particularly relevant for evaluating how ecological finance mechanisms support sustainable environmental management in the Nigerian real estate sector. Ecological finance tools such as ecological funds, ecological support and ecological rights aim to reduce the environmental footprint of real estate development. These instruments facilitate investments in energy-efficient construction, sustainable building materials, and compliance with environmental regulations. This aligns with the TBL's environmental component by promoting eco-conscious development in Nigeria’s rapidly growing real estate industry. The adoption of ecological finance fosters corporate practices that benefit the wider community. For instance, real estate firms utilizing ecological support to implement sustainable waste management or green landscaping contribute to healthier urban environments. Such practices strengthen stakeholder relations and uphold the social responsibility aspect of the TBL model. The profit dimension of TBL is achieved through the financial sustainability of eco-friendly investments. Ecological finance enables real estate developers to access capital while improving their environmental credentials. Investments in ecological rights can lead to operational cost savings (e.g., lower energy bills) and enhanced investor confidence, thereby boosting long-term profitability.

2.5.2 Environmental Economics Theory

Environmental Economics emerged as a distinct discipline in the 20th century, pioneered by Arthur Cecil Pigou (1912) through his work on externalities. This was later expanded by scholars such as Ronald Coase (1960),


Int J Engg Mgmt Res 2025;15(2)5
Hussaini I, et al. Ecological Finance and Sustainable Environmental Management

who emphasized negotiated solutions to environmental issues, and William Nordhaus (1970s), who explored the economic implications of climate change. Environmental economics advocates for the internalization of environmental costs into market systems through mechanisms such as taxes, incentives, and policy instruments. Ecological finance is an application of this theory, as it incentivizes environmentally responsible behavior and reorients capital flows toward sustainable activities. In the Nigerian real estate context, ecological funds can be mobilized to finance projects like solar-powered estates or wastewater recycling facilities. These instruments help real estate institutions reduce their carbon footprints while complying with green building regulations. The environmental economics perspective underscores the need to value such ecosystem services in economic terms (Koundouri et al., 2022). Access to ecological support, such as low-interest loans for eco-compliant projects, empowers developers to adopt cleaner technologies and sustainable designs. This aligns with environmental economic principles that stress financial mechanisms as levers for positive environmental change (OECD, 2023). With ESG investing gaining traction globally, ecological rights investments in projects aligned with environmental goals are increasingly appealing to both institutional and individual investors. By encouraging capital allocation toward sustainable urban infrastructure, real estate firms can enhance both ecological value and long-term investor returns (UNEP FI, 2022). Ecological interest, akin to environmental insurance, helps firms hedge against risks such as flooding, soil erosion, or regulatory penalties. Environmental economics supports such instruments as risk-sharing mechanisms that drive proactive environmental planning and compliance (IPCC, 2023). In sum, environmental economics provides a robust theoretical lens through which to assess the integration of ecological finance in Nigeria’s real estate institutions. By aligning economic incentives with sustainability goals, firms are better positioned to contribute to long-term environmental stewardship and responsible urban development.

3. Methodology

This study adopts an ex-post facto research design, which is suitable for exploring causal relationships where variables cannot be manipulated directly (Hair et al., 2019).

A quantitative approach relying on secondary data was employed to investigate the role of ecological finance in sustainable environmental management. The population consists of all ten real estate institutions listed on the Nigerian Exchange Group (NGX) as of April 10, 2025. Given their small number, census sampling was used to include all listed firms. The study period spans ten years, from 2015 to 2024. Data were sourced from the annual reports of the listed firms, retrieved from their official websites. These reports are recognized for their credibility and comprehensiveness, consistent with the criteria established by Deegan and Rankin (1997) and Abdul Rahman (2001). Descriptive and inferential statistics were used for analysis, and the statistical package STATA 17 version facilitated data processing. This approach ensures both analytical rigor and empirical reliability in uncovering how ecological finance instruments impact environmental outcomes in the Nigerian real estate sector.

Sustainable Environmental Management (SustManage) reports the highest mean value, suggesting strong environmental engagement among sampled real estate firms. Ecological Interest reflects the lowest mean, implying it is the least adopted ecological finance tool. Distribution measures reveal a fairly normal spread, supporting the reliability of the dataset. These findings are consistent with Kim & Bai (2023), who identified ecological insurance (interest) as underutilized due to policy and awareness gaps in developing nations.

All ecological finance components significantly and positively affect sustainable environmental management. Ecological Right (β = 1.05) emerges as the strongest predictor. These results align with Adomako et al. (2023), who emphasize that real estate investments anchored on ecological principles can drive green infrastructure development and sustainability transitions in urban economies.

The significant p-value indicates heteroskedasticity in the model. Thus, robust or generalized least squares estimation is necessary to ensure valid inference. According to Mensah & Ibrahim (2024), correcting for heteroskedasticity is essential in sustainability-focused econometric models to avoid distorted policy implications.

All VIF values are below the threshold of 10, confirming that multicollinearity is not a concern. This ensures that the estimates are stable and that the individual effects of the ecological finance tools are interpretable. As noted by Ofori-Atta & Kwarteng (2023), maintaining low collinearity enhances the explanatory power of sustainable finance models in African economies.

The results from Table 7 show the Ramsey RESET test used to assess model specification. The test statistic is 2.67 with 3 degrees of freedom and a p-value of 0.094. Since the p-value exceeds the 5% significance level, the null hypothesis that the model is correctly specified—is not rejected. This suggests that there is no significant evidence of misspecification, and the functional form of the model is adequate. This finding supports previous studies, such as García et al. (2022), which emphasized that correctly specified models improve the detection of irregularities. Similarly, Klein and Zimmermann (2021) found that well-specified models in forensic analytics yield more robust and interpretable results, reinforcing the reliability of the conclusions in this study.

Table 8 presents the results of the regression model. All predictor variables—EcFund, EcSupport, EcRight, and EcInterest are statistically significant, with p-values less than 0.05.

Specifically: EcFund has a coefficient of 0.85 (p = 0.0000), indicating that a unit increase in EcFund is associated with a 0.85 increase in Sustainable Environmental Management. EcSupport has a coefficient of 0.70 (p = 0.0003), showing a positive relationship with environmental management.

EcRight has the highest coefficient at 1.05 (p = 0.0000), reflecting the strongest influence on environmental management. EcInterest has a coefficient of 0.65 (p = 0.0000), also indicating a positive effect. The robust standard errors confirm the reliability of these results by accounting for heteroscedasticity. The R² value of 0.62 shows that the model explains 62% of the variance in Sustainable Environmental Management, indicating a good model fit. These results align with prior research highlighting the significant role of ecological finance tools in fostering better financial and environmental outcomes, reinforcing the need for firms to diversify their ecological finance portfolios.

Table 9 presents an analysis of outliers and influential observations using Cook's Distance. The mean Cook’s Distance is 0.025, with a maximum value of 0.15. The threshold for identifying influential observations is set at 0.020. Since the maximum value exceeds the threshold, this indicates that certain observations may disproportionately influence the results. Investigating these points further is crucial to ensure the robustness of the regression model and ensure that the analysis reflects the broader population.

3.3 Summary

This study explores the effect of ecological finance on sustainable environmental management within listed real estate institutions in Nigeria. It highlights that environmental degradation from urban development can be mitigated through the adoption of ecological financial mechanisms. Using financial and sustainability reports from selected firms, econometric techniques were applied to assess the relationship between ecological finance tools and environmental planning efforts.

Key findings suggest a strong positive relationship, indicating that firms utilizing ecological finance tools are better at implementing effective environmental management strategies. Ecological funds and credits, in particular, have shown positive impacts on environmental innovation and compliance. However, challenges such as inadequate ecological finance policies and limited awareness hinder broader adoption. This study provides significant insights into ecological finance within the Nigerian real estate sector and suggests improvements in policy and practice to foster sustainable urban development.

3.4 Conclusion

Ecological finance significantly enhances sustainable environmental management in Nigeria’s real estate industry. Firms adopting ecological financial practices are better prepared for environmental risks and more committed to sustainable practices. While ecological finance is underutilized in Nigeria, its transformative potential for both environmental and economic development is clear. Institutional support, policy reforms, and market innovations are key to scaling its impact.

3.5 Recommendations

i. Strengthen Regulatory Frameworks: The government should implement and enforce policies supporting ecological finance to encourage environmentally responsible corporate behavior.
ii. Promote Awareness and Capacity Building: Stakeholders, especially in the real estate industry, should be educated on the benefits and applications of ecological finance tools.
iii. Facilitate Access to Ecological Instruments: Financial institutions should create tailored ecological finance products accessible to firms at different stages of environmental planning.
iv. Mandate Sustainability Reporting: Regulatory bodies should require listed companies to disclose their environmental planning efforts and usage of ecological finance tools in annual reports.
v. Enhance Public-Private Collaboration: Encourage partnerships that combine public funding with private investment in ecological technologies.

3.6 Limitations of the Study

i. The study was constrained by the availability of comprehensive ecological finance and environmental planning data, reducing the sample size.

ii. The study period may not fully capture long-term trends or delayed effects of ecological finance initiatives.
iii. The analysis treated the real estate sector as homogeneous, potentially overlooking sub-sector variations.

3.7 Suggestions for Further Studies

i. Future research should adopt extended timeframes to capture the long-term impacts of ecological finance.
ii. In-depth studies on specific sub-sectors (e.g., residential, commercial, industrial) could yield more precise insights.
iii. Research on how corporate governance and institutional quality affect the relationship between ecological finance and environmental management.
iv. Cross-country analyses can uncover best practices and contextual factors influencing ecological finance adoption.
