The global transition towards renewable energy sources represents a critical step in combating climate change and achieving sustainable development goals. Renewable energy technologies, such as solar, wind, hydroelectric, and geothermal power, offer promising alternatives to traditional fossil fuels by harnessing natural resources with minimal environmental impact. As governments, corporations, and consumers increasingly prioritize clean energy solutions, the renewable energy sector has experienced unprecedented growth and innovation. However, alongside this expansion, there arises a pressing need to ensure the sustainability of the entire supply chain associated with renewable energy technologies. The supply chain for renewable energy encompasses a complex network of interconnected processes, including the extraction of raw materials, manufacturing of components, transportation, installation, operation, maintenance, and decommissioning of renewable energy systems. Each stage of this supply chain presents unique challenges and risks related to environmental degradation, social equity, and economic sustainability. For instance, the mining of rare earth metals and minerals required for solar panels, wind turbines, and batteries often involves environmentally destructive practices and labor rights violations in some regions of the world (Peng et al., 2020). Moreover, the transportation and logistics involved in sourcing components from multiple countries can contribute to carbon emissions and exacerbate environmental footprints (Arvesen et al., 2020). In response to these challenges, certification programs have emerged as a means to promote sustainability and responsible business practices within the renewable energy supply chain. Certification schemes, such as the International Organization for Standardization (ISO) standards, Leadership in Energy and Environmental Design (LEED), and various industry-specific certifications, aim to establish criteria and guidelines for sustainable operations, product design, and supply chain management (Zeng et al., 2021). These certification programs typically assess and verify compliance with environmental, social, and governance (ESG) criteria, including but not limited to resource efficiency, labor rights, community engagement, and transparency. The proliferation of certification programs within the renewable energy sector reflects a growing recognition of the interconnectedness between environmental stewardship, social responsibility, and economic viability. By adhering to established sustainability standards, renewable energy companies seek to enhance their reputation, mitigate risks, and gain competitive advantages in the marketplace (Tervooren & Madhok, 2019). Moreover, certification programs provide assurance to investors, regulators, and consumers that renewable energy products and services meet rigorous sustainability criteria and align with global best practices. Despite the proliferation of certification initiatives, questions remain regarding their effectiveness in achieving meaningful improvements in supply chain sustainability within the renewable energy sector. While certification schemes offer a framework for assessing and benchmarking performance, their implementation and impact vary widely across different contexts and geographic regions. Furthermore, challenges such as greenwashing, limited stakeholder engagement, and lack of enforcement mechanisms can undermine the credibility and efficacy of certification programs (Peng et al., 2020). Therefore, there is a need for empirical research to evaluate the strengths, limitations, and outcomes of certification initiatives in ensuring supply chain sustainability in the renewable energy sector. This qualitative research aims to address this gap in the literature by examining the effectiveness of certification programs in promoting sustainability within the renewable energy supply chain. Through in-depth interviews with key stakeholders, including renewable energy companies, certification bodies, NGOs, and government agencies, this study seeks to understand the perceptions, experiences, and challenges associated with certification initiatives. Additionally, content analysis of relevant documents, reports, and industry publications will provide insights into the evolution, trends, and impacts of certification programs on supply chain sustainability. By elucidating the complex dynamics of certification in the renewable energy sector, this research contributes to the broader discourse on sustainable supply chain management and corporate responsibility. The findings of this study will inform policymakers, industry practitioners, and certification bodies about the strengths and weaknesses of existing certification frameworks and suggest strategies for enhancing their effectiveness in promoting sustainable practices across the renewable energy supply chain. Ultimately, this research seeks to advance our understanding of the role of certification programs in shaping the transition towards a more sustainable and resilient energy future.

The literature on certification programs in ensuring supply chain sustainability within the renewable energy sector offers valuable insights into the motivations, mechanisms, challenges, and outcomes of certification initiatives. Certification programs, such as ISO standards, LEED, and industry-specific certifications, have gained prominence as tools for promoting environmental responsibility, social equity, and ethical sourcing practices across the renewable energy supply chain. Drawing on recent research and industry reports, this literature review synthesizes key findings and debates surrounding certification programs in the context of renewable energy. Certification programs play a crucial role in addressing sustainability challenges associated with the extraction, production, and utilization of renewable energy technologies. Scholars have underscored the importance of certification schemes in providing a standardized framework for assessing and benchmarking sustainability performance across the renewable energy supply chain (Zeng et al., 2021). For instance, ISO 14001 certification focuses on environmental management systems, while ISO 50001 addresses energy management, offering guidelines for organizations to improve energy performance and reduce environmental impacts (World Bank Group, 2018). Similarly, industry-specific certifications, such as the Solar Energy Industries Association's (SEIA) SolarAPP+ program, aim to streamline permitting processes and ensure compliance with regulatory requirements for solar installations (Solar Energy Industries Association, 2022). The adoption of certification programs in the renewable energy sector is driven by various factors, including regulatory pressures, market demand for sustainable products, and corporate social responsibility (CSR) commitments. Peng et al. (2020) highlight the role of regulatory frameworks and government incentives in incentivizing companies to pursue certification and adhere to sustainability standards. An analysis of the good and bad impacts of cultural norms on sustainable entrepreneurship in the small and medium enterprise (SME) sector of Bangladesh is presented in a recent research. The importance of government policies in influencing sustainable habits is highlighted, and there should be all-encompassing plans to overcome cultural obstacles (Emon & Khan, 2023). A literature study looks at the dynamics of gender in Bangladeshi entrepreneurship, revealing the challenges women confront and the ways the government is trying to help them. Emon and Nipa (2024) highlight the importance of focused policies and research in promoting inclusive entrepreneurship, which can be used as a resource by stakeholders and policymakers. By focusing on relationships between service aspects and patient happiness, this research investigates how technology affects service quality and satisfaction in hospitals. Emon et al. (2023) urge further study to enhance tactics and recommends boosting responsiveness, assurance, and communication while addressing patient preferences on technology usage. Promoting sustainable energy requires more information distribution and the elimination of adoption hurdles including price and availability via incentives and joint efforts, according to a research that assesses public understanding and perception of solar technology (Hasan Emon, 2023). Focusing on solar home systems (SHS) in rural Bangladesh, this research investigates the challenges that residents face while trying to use RET. The policy framework for broad adoption of RET is informed by the findings, which emphasize use limits and demand-supply hurdles. This adoption is vital for sustainable development and poverty reduction (Khan et al., 2020). By conducting in-depth qualitative interviews with forty different stakeholders, this study seeks to understand the pros and cons of integrating renewable energy sources into Dhaka's power grid. Although solar and wind power are becoming more well-known, obstacles such as expensive prices and limited infrastructure are preventing their widespread use. Emphasizing the need of partnership between the government, commercial sector, and civil society, the proposed initiatives for a greener and more resilient energy future in Dhaka include public awareness campaigns and regulatory frameworks (Emon & Khan, 2023). Researchers in Bangladesh looked at the effects of SRM on supply chain cost efficiency and found that two key factors were supplier collaboration and long-term relationships. This research highlights the strategic relevance of supply chain risk management in developing economies and gives practical insights for improving supply chain performance, despite its limits (Emon et al., 2024). The impact of emotional intelligence and education on long-term behavior modification among Bangladeshi university students is investigated in a qualitative case study. Hasan and Chowdhury (2023) found that sustainable development activities may be informed by education's function in promoting awareness and emotional intelligence's contribution to social skills and empathy. Family income, tuition costs, career chances, and university reputation are among of the elements that impact students' decisions while choosing a higher education school in Dhaka, according to a survey. According to Emon et al. (2023), institutions and policymakers in Bangladesh may get valuable insights by considering personal interests, parental attitudes, location, amenities, and security. The purpose of this research is to learn about the solar revolution in Bangladesh from the viewpoints of its users in order to comprehend its effects and spot any problems or possibilities. Policy and practice in poor nations are informed by qualitative approaches with 40 participants utilizing solar systems in rural and urban regions. This research contributes to the growing body of literature on renewable energy (Hasan & Emon, 2023). The policy implications of a thorough assessment on the causes and effects of price hikes in Bangladesh are highlighted. Emon (2023) proposes measures to limit inflation, promote competition, and increase supply chain efficiency in order to reduce negative consequences and stabilize the economy. In countries with stringent environmental regulations and carbon pricing mechanisms, renewable energy companies face greater pressure to demonstrate compliance with certification requirements to access markets and attract investment (Peng et al., 2020). Moreover, consumer preferences for eco-friendly products and brands have spurred companies to pursue certification as a means of enhancing brand reputation and market competitiveness (Tervooren & Madhok, 2019). However, the effectiveness of certification programs in achieving supply chain sustainability goals within the renewable energy sector is subject to debate. While certification schemes offer a structured approach to assessing and managing sustainability risks, critics argue that they may fall short in driving meaningful change and addressing systemic issues such as environmental degradation, human rights violations, and unequal distribution of benefits (Arvesen et al., 2020). Greenwashing, whereby companies use certification labels to convey a misleading impression of sustainability without substantively improving practices, is a pervasive concern (Peng et al., 2020). Limited transparency and accountability mechanisms within certification programs can undermine their credibility and erode trust among stakeholders (Zeng et al., 2021). Moreover, the complex and global nature of renewable energy supply chains poses challenges for effective certification implementation and oversight. Supply chains for renewable energy technologies often span multiple countries and involve diverse stakeholders, each with unique regulatory environments, cultural norms, and socio-economic conditions (World Bank Group, 2018). Ensuring consistent compliance with certification requirements across diverse contexts and value chain stages requires robust monitoring, auditing, and verification mechanisms. However, resource constraints, capacity gaps, and information asymmetries may hinder the efficacy of certification programs in detecting and addressing non-compliance (Arvesen et al., 2020). Furthermore, certification programs face criticisms regarding their focus on procedural compliance rather than substantive outcomes. While certifications provide assurance of adherence to predefined criteria and standards, they may not always translate into tangible improvements in environmental performance, social equity, or economic resilience (Tervooren & Madhok, 2019). The disconnect between certification and real-world impact underscores the need for holistic approaches to sustainability that consider the broader systemic challenges and interdependencies within the renewable energy sector (Zeng et al., 2021). In response to these challenges, scholars and practitioners advocate for continuous improvement and innovation in certification programs to enhance their relevance, rigor, and effectiveness. This includes greater stakeholder engagement, transparency, and accountability in certification processes, as well as the integration of emerging technologies such as blockchain and satellite imaging for enhanced traceability and verification of supply chain sustainability claims (Peng et al., 2020). Additionally, there is a growing emphasis on multi-stakeholder collaboration and collective action initiatives to address systemic sustainability challenges and promote sector-wide transformation (World Bank Group, 2018).

The research methodology employed in this study aimed to investigate the effectiveness of certification programs in ensuring supply chain sustainability within the renewable energy sector. A qualitative approach was chosen to gain insights into the perceptions, experiences, and challenges associated with certification initiatives from key stakeholders. Semi-structured interviews were conducted with a diverse range of participants, including representatives from renewable energy companies, certification bodies, non-governmental organizations (NGOs), and government agencies. Purposive sampling was utilized to select participants with relevant expertise and experience in sustainable supply chain management and certification processes. A total of 20 interviews were conducted between October 2023 and January 2024. The interviews were conducted virtually using video conferencing platforms, allowing for flexibility and accessibility for participants located in different geographic regions. Each interview lasted approximately 60-90 minutes and was audio-recorded with the consent of the participants. An interview guide was developed to ensure consistency and comprehensiveness across interviews, covering topics such as the motivations for pursuing certification, experiences with certification processes, perceived benefits and challenges, and suggestions for improving certification effectiveness. In addition to interviews, content analysis was employed to analyze relevant documents, reports, and industry publications pertaining to certification programs and supply chain sustainability in the renewable energy sector. This included reviewing academic literature, industry reports, certification standards and guidelines, corporate sustainability reports, and press releases. The content analysis aimed to complement and contextualize the insights gathered from interviews, providing a broader understanding of the evolving landscape of certification initiatives and their impacts on supply chain sustainability. Data analysis was conducted iteratively and thematically to identify patterns, trends, and recurring themes within the interview transcripts and document corpus. Transcripts were first transcribed verbatim and then coded using a combination of deductive and inductive approaches. Deductive codes were derived from the interview guide and existing literature on certification programs and supply chain sustainability, while inductive codes emerged from the data through open coding and constant comparison. Themes and sub-themes were developed based on the coded data, and connections between themes were explored to elucidate overarching narratives and insights. The triangulation of data sources, including interviews and content analysis, facilitated a comprehensive and nuanced understanding of the research topic. By integrating perspectives from multiple stakeholders and examining both qualitative and documentary evidence, this study aimed to provide rich insights into the effectiveness of certification programs in promoting supply chain sustainability within the renewable energy sector.
