1. Introduction

The tourism sector's increasing contribution to global CO2 emissions, estimated at 4.9%, emphasizes the urgency for sustainability (European Climate Foundation, 2014). In the hospitality industry, Net Zero represents a comprehensive commitment to balancing greenhouse gas emissions with equivalent removal efforts, extending beyond energy and travel-related reductions to encompass waste minimization, water efficiency, sustainable food and beverage practices, and environmentally responsible building design. Achieving Net Zero requires a methodical reduction of emissions by enhancing efficiency, embracing renewable energy sources, and managing resources responsibly, while also tackling unavoidable emissions via carbon offset strategies and nature-based solutions. This methodology aims to significantly diminish the sector's climate impact and bolster environmental stewardship within travel and hospitality operations (United Nations, n.d.; Oxford Net Zero, n.d.).

Due to the substantial contribution of tourism-related activities particularly transportation, accommodation, and energy-intensive hospitality operations to greenhouse gas emissions, Malaysia's hospitality sector faces a critical challenge in progressing toward Net Zero, especially as tourism growth is positively associated with rising national CO₂ emissions (Lenzen et al., 2018; UNWTO, n.d.; Zaman et al., 2022). Pursuing this goal can combat climate change, protect Malaysia's diverse ecosystems and foster biodiversity conservation. Malaysia possesses a rich history of environmental involvement, which can be traced back to its engagement in the 1972 UN Conference on the Human Environment, as well as its dedication to international accords such as the Paris Agreement. Nevertheless, recent statistics indicate that CO2 emissions from tourism in Malaysia may increase by 25% by the year 2030, surpassing optimistic projections (UNWTO & ITF, 2019). Currently, tourism accounts for 8-11% of global emissions, with the aviation sector alone contributing 17%. Forecasts suggest that if tourist arrivals were to double, there could be a potential 5.3% share of anthropogenic carbon emissions by 2030. This necessitates urgent climate action within the industry (UN, n.d.; UNWTO, n.d.; Usborne, 2022; SEDA, n.d., IEA, 2020; Chua & Oh, 2010; Lim et al 2006).

The pursuit of Net Zero in Malaysia's hospitality industry aligns closely with national climate objectives while enhancing industry competitiveness by attracting eco-conscious tourists and strengthening long-term financial viability through improved energy efficiency and resource management. The implementation of sustainability initiatives enhances a corporation's reputation, strengthens customer loyalty, and promotes positive branding. This enhancement is underpinned by a strong commitment from the government through various policies and initiatives, such as the National Green Technology Policy (NGTP), Green Investment Tax Allowance (GITA), Green Income Tax Exemption (GITE), MyCarbon, Green Technology Financing Scheme (GTFS), Low Carbon Cities Framework, Green Technology Park Malaysia, Green Building Index (GBI), National Transport Policy (NTP), Malaysia Intelligent Transport System Blueprint (MITSB), National Land Public Transport Master Plan (NLPTMP), and National Solid Waste Management Policy (NSWMP). Collectively, these initiatives provide incentives, regulatory support, and financing options for transitioning to sustainability (Ministry of Energy, Green Technology & Water Malaysia, 2009; 2017; Malaysia Green Technology and Climate Change Corporation, 2023; GBI Sdn Bhd, n.d.; Ministry of Transport, 2019; Ministry of Works, 2019; Ministry of Natural Resources and Environment, 2015; Ministry of Local Government Development, 2016; Government of Malaysia, n.d.; IEA, 2020).

The urgency for Net Zero adoption is underscored by Malaysia's 2021 CO₂ emissions of 251.6 million tonnes and a growth rate of 6.12%, with the energy-intensive hospitality sector contributing significantly to greenhouse gas emissions (Knoema, n.d.; Rahim, 2014; European Climate Foundation, 2014). The industry also faces persistent environmental challenges, including energy and water inefficiency, waste generation, single-use plastics, pollution, ecological degradation, and climate vulnerability, which increase operational costs and threaten tourism resilience (Mukaramah et al., 2021; Babatunde et al., 2018). Addressing these challenges through Net Zero-aligned mitigation strategies is essential for climate resilience, economic development, cultural heritage preservation, and fulfilling corporate social responsibility, positioning Malaysia's hospitality industry as a responsible contributor to sustainable tourism and national sustainability goals.

The aim of this research is to present a thorough theoretical framework for the Malaysian hospitality sector to achieve Net Zero status by tackling major environmental issues through sustainable practices. By integrating principles of sustainable development, systems thinking, and Corporate Social Responsibility (CSR) across multiple fields, it addresses concerns such as emissions, energy consumption, water usage, waste production, and ecological effects. The framework promotes the reduction of carbon footprints via efficiency improvements, renewable energy adoption, and responsible stewardship or resources, in addition to carbon offsetting methods. Ultimately, it seeks to empower the industry to proactively address climate change, protect the environment, and encourage responsible tourism in Malaysia.

2. Literature Review

The referenced papers collectively offer valuable insights into the theoretical framework and prior research related to achieving net-zero emissions. Mishra et al. (2022) undertook a systematic literature review examining key themes related to the net-zero economy, with particular emphasis on decarbonization, emission mitigation, and supply chain management. The study shows a strong positive correlation between digitalization, circular economy practices, and the advancement of netzero goals, while also highlighting the fact that the majority of current research is focused on decarbonization strategies, emission control mechanisms, and life cycle assessment. Asif et al. (2023) utilized data from the Carbon Disclosure Project to identify environmental sustainability factors aiding businesses in achieving pollution reduction targets and sustainable business models. Huang et al. (2013) explored energy-saving and emission reduction opportunities within China's hospitality sector, proposing a foundation for carbon emission assessment modelling. Jones (2023) investigated how the tourism industry addresses net-zero emissions challenges and highlighted transition strategies employed by industry leaders. Talib (2019) addresses the implementation of Sustainable Facilities Management (SFM) in the hotel industry, identifying multiple initiatives that can support effective sustainable facilities management practices. These papers, when considered together, enhance the understanding of net-zero initiatives and provide critical insights for developing a theoretical framework focused on reaching net-zero emissions in Malaysia's hospitality industry.

The proposed Net Zero framework for Malaysia's hospitality industry is grounded in sustainable development principles (WCED, 1987) and systems thinking (MIT Sloan School of Management, 2023), recognizing the sector's interconnected relationship with the environment, society, and the economy. Aligned with global climate ambitions, the framework adopts a multidisciplinary perspective that integrates environmental, economic, social, and policy dimensions to promote holistic sustainability. It extends beyond energy efficiency to encompass waste management, water stewardship, sustainable procurement, and community engagement as essential components of emission reduction. Central to the framework is collaborative stakeholder involvement, bringing together industry professionals, investors, policymakers, local communities, and non-governmental organizations. By embedding Corporate Social Responsibility (CSR) and sustainable business practices, the framework reinforces organizational accountability, transparency, and ethical governance. With an emphasis on Goals 13 (Climate Action) and 12 (Responsible Consumption and Production), these principles promote alignment with global sustainability agendas and help steer the hospitality sector toward a resilient and balanced Net Zero transition.

The theoretical perspective underpinning the proposed framework is grounded in systems thinking, which acknowledges the complex interdependencies within the hospitality industry and its interactions with the environment and local communities. By adopting a holistic approach, the framework seeks to address these interconnected relationships comprehensively, minimizing unintended consequences and promoting balanced outcomes that support both environmental integrity and economic viability. In order to put this perspective into practice, System Dynamics (SD), established by Prof. Emeritus Jay W. Forrester at MIT Sloan in the 1950s, serves as a conceptual and analytical framework. SD allows for the investigation of dynamic system behaviour over time, making it particularly applicable to the tourism and hospitality field, where numerous subsystems engage and change in response to internal and external stimuli.

Global sustainability agendas, systems thinking, system dynamics, corporate social responsibility, and sustainable development concepts are all integrated into the theoretical underpinnings of the suggested Net Zero framework. Through integrated sustainability strategies, stakeholder participation, and accountability mechanisms, it acknowledges the complex effects of the hotel industry on environmental and social systems and offers a methodical route to reaching Net Zero. Through this approach, the framework aims to guide the industry toward a more environmentally responsible, socially conscious, and resilient future.

In Malaysia, the adoption of environmentally friendly hotel practices lags behind European nations, with recent attention to sustainability (Yusof & Jamaludin, 2013). Tourism Malaysia (2016) notes a low and stagnant number of hotels in Malaysia implementing sustainable methods. Although there is a rising awareness of environmental sustainability in the hospitality industry, the execution of green initiatives in Malaysian resorts and hotels is still limited, largely due to the focus on short-term financial returns over the benefits of long-term sustainability. Siti et al. (2011) discovered that revenue generating took precedence over sustainability, with little adoption of green and sustainable efforts, frequently as a result of the perception of unappealing benefits. Kamalulariffin et al. (2013) identified five key barriers to environmental management adoption in Malaysian hotels, finding that only organizational-level greenness partially supported implementation. Similarly, Yusof and Jamaludin (2013, 2014) discovered that Malaysian green hotels focused predominantly on energy, waste, and water management due to immediate cost reduction benefits, while neglecting areas with less direct financial impact such as indoor air quality and sustainable site management. Kasim (2009) further explored how managerial attitudes in small and medium hotels influenced environmental management approaches. Recent research substantiates this consistent trend, showing that despite the efforts of government certification, only a small percentage of Malaysia's 750 rated accommodation facilities have received green certification, as hotels persist in prioritizing cost-saving approaches and immediate benefits over extensive sustainable practices (Luo et al., 2021). The majority of Malaysian hotels have instituted basic eco-friendly measures in their restaurant operations, such as conserving energy and water, sourcing locally, and managing waste, which are prevalent in the hotel industry of the country (Yusof & Jamaludin, 2013; Anton, Deltas, & Khanna, 2004; Wang, 2012; Langgat, 2019). Nonetheless, researchers and environmental organizations are increasingly concerned about the environmental impact of the industry and the pressing need for sustainable practices (Dief & Font, 2010; Nicholls & Kang, 2012a, 2012b; Hu, 2012; Kasim & Ismail, 2012; Kim et al., 2017). Current research trends in sustainable hospitality, as shown by studies such as Miao & Wei (2013), Hu (2012), Theotokis & Manganari (2015), and Millar, Hind, & Magala (2012), concentrate on the effects of green practices on consumer profiles.

Platas (2023) discusses the hotel sector's carbon footprint on a global scale and the reports on a CBRE Hotels Research study examining CO2 emissions across the international hospitality industry, comparing data from 25 countries including the US, UK, Germany, Spain, UAE, Saudi Arabia, Japan, Vietnam, France, Colombia, Indonesia, Egypt, and Malaysia. While Malaysia is briefly mentioned as one of the countries with high water usage per occupied room alongside Vietnam and Egypt, the study primary focus is on the urgent need for the entire global hotel industry to reduce carbon emissions and improve environmental, social, and governance (ESG) performance across different regions. This is a global industry analysis that includes Malaysia as one of many countries examined. Covering accommodation, food services, transportation, and entertainment, the industry is responsible for emissions stemming from energy consumption, transportation, food services, water

usage, waste generation, infrastructure, construction, business travel, and supply chains. Specifically, hotels and resorts demand a large amount of energy, resulting in direct CO2 and greenhouse gas emissions (Yusof & Jamaludin, 2013). Tourism-related transportation emits CO2 and air pollutants. Food and beverage operations contribute emissions across the supply chain, while water consumption indirectly contributes if powered by carbon-intensive sources. The industry generates significant waste, with improper disposal releasing greenhouse gases like methane (CH4). Construction and expansion processes are energy-intensive, and business travel adds to emissions. The manufacturing and distribution of goods and services within the hospitality industry significantly impact its carbon footprint. A report by CBRE indicates that as of March 2023, the hotel industry is assessed at a CO2 rating of 96, emphasizing the pressing necessity for global efforts to reduce carbon emissions (Platas, 2023). Tackling these emissions through energy efficiency, renewable energy adoption, water optimization, waste reduction, and sustainable transportation is critical for the industry's role in combatting climate change and promoting global sustainability.

Effective collaboration among stakeholders in hospitality industry is essential for addressing challenges, fostering responsible tourism, and shaping guest experiences. However, the industry's considerable environmental footprint, stemming from water usage, energy consumption, waste generation, and tourism concentration, poses threats to ecosystems and communities. Adopting sustainable initiatives, including conservation, waste minimisation, and cultural preservation, is essential to mitigate these impacts. Transparent communication and collaboration are paramount to promote responsible and sustainable tourism, ensuring the preservation of natural resources and benefiting local communities. Embracing sustainability has the potential to redefine the hospitality sector, turning it into a positive force for environmental sustainability and social consequences.

In Malaysia, the hospitality industry is increasingly adopting sustainable practices through various initiatives, such as acquiring green building certifications, implementing energy-efficient technologies, and utilizing renewable energy sources to minimize carbon footprints, as guided by GBI tools (Green Building Index, 2022). Significantly, four hotels received certification under the ASEAN Green Hotel Standard in 2022 (The Malaysian Reserve, 2023), and in 2014, there were 29 hotels and 448 projects registered with the Green Building Index (GBI) (GBI, 2014). While water conservation measures like water reuse systems and low-flow fixtures address water scarcity, waste reduction, recycling, and locally sourced organic food are also becoming more common practices. These initiatives show the industry's commitment to sustainability and help Malaysia's hospitality sector become more ecologically conscious.

Reaching Net Zero in the Malaysian hospitality industry faces obstacles including a lack of industrywide awareness, financial limitations for smaller businesses, and the difficulties associated with maintaining sustainability throughout the supply chain, especially in food procurement. Accelerating Net Zero initiatives necessitates clear policies, standardized data collection, and a cultural shift among staff and guests. Integrated approaches addressing energy efficiency, waste reduction, and water conservation are indispensable. Despite these obstacles, the industry is aggressively pursuing sustainability and recognizing the need for Net Zero. In order to overcome challenges and make the shift to a more sustainable and Net Zero-compliant hospitality industry in Malaysia, enterprises, the government, non-governmental organizations, and communities must work together. This will greatly contribute to both national climate goals and international sustainability initiatives.

Net Zero in Malaysia's hospitality industry is a comprehensive goal aiming to offset all greenhouse gas emissions from operations through removals from the atmosphere. Malaysia's commitment to achieve Net Zero by 2050 is outlined in its Long-Term Low Emissions Development Strategy (LT-LEDS), aligning with UNFCCC objectives. In the hospitality sector, Net Zero principles prioritize emission reduction via energy efficiency, waste management, and renewable energy.

Collaboration among stakeholders, supported by robust policies, ensures collective sustainability action with transparent reporting. Embracing innovation and sustainable technologies propels the industry toward Net Zero, positioning Malaysia's hospitality as a leader in sustainable tourism and responsible business. This commitment aligns with national climate goals, fostering environmental preservation (BNM Annual Report, 2022).

The Greenhouse Gas Protocol's three primary scopes are used to control greenhouse gas emissions in Malaysia's hospitality sector (World Resources Institute and World Business Council, 2004). Direct emissions from on-site sources, such as the burning of fossil fuels and the use of refrigerants, are included in scope 1. Scope 2 covers indirect emissions associated with purchased electricity, whereas Scope 3 covers external emissions associated with operations such as waste disposal, worker and guest transportation, and the manufacture and transportation of commodities. Achieving Net Zero in the hospitality industry necessitates comprehensive strategies targeting all these emission scopes. This involves the reduction of emissions through energy-efficient technologies, adoption of renewables, and engagement in carbon offsetting activities, aligning establishments with sustainability and environmental preservation goals.

In order to achieve sustainability and Net Zero targets, Malaysia's hospitality sector must prioritize both carbon reduction and offsetting techniques. Reducing carbon emissions entails implementing effective strategies and technology that improve long-term sustainability and customer appeal. At the same time, carbon offsetting makes up for residual emissions, accelerating the process of reaching Net Zero and demonstrating a prompt dedication to environmental care. When combined, these tactics help Malaysia's hotel industry fight climate change, save resources, and encourage ethical travel.

Government's commitment to environmental sustainability in the hospitality sector is evident through various legislations and policies. Malaysia's National Policy on Climate Change outlines emission reduction targets and sustainable practices, impacting hospitality and tourism. The National Energy Efficiency Action Plan promotes energy-saving technologies across sectors, including hospitality. The Green Technology Master Plan encourages eco-friendly practices and renewable energy adoption in tourism and hospitality.

The Environmental Quality Act sets standards for waste, air, and water quality, affecting hospitality operations. Mandatory Environmental Impact Assessments under this act ensure environmental considerations in hospitality development projects. Eco-friendly methods are encouraged by Sustainable Tourism Development guidelines, while trash minimization is emphasized by the Solid trash and Public Cleansing Management Act. Sustainability in the hospitality industry is encouraged by initiatives like the Green Building Index and MyHIJAU Mark. In order to promote responsible tourism and correspond with Malaysia's environmental aims, it is imperative that these policies be monitored (Bhuiyan and Ismail, 2018; Jalal & Bodger, 2009).

Sustainability has been successfully promoted by current environmental regulations in Malaysia's hospitality industry, including the National Policy on Climate Change, National Energy Efficiency Action Plan (NEEAP), Green Technology Master Plan, and Sustainable Tourism Development Guidelines. However, there are notable gaps in enforcement, compliance, incentives, circular economy integration, Extended Producer Responsibility (EPR), public awareness, Small Medium Enterprise (SME) support, and monitoring/reporting. Strengthening enforcement, offering incentives for sustainable practices, integrating circular economy principles, implementing EPR programs, and raising public awareness are crucial. Support for SMEs and improved monitoring/reporting mechanisms will enhance Malaysia's alignment with global environmental goals and promote responsible tourism.

To propel Malaysia's hospitality industry toward Net Zero, imperative policy recommendations include mandatory emission reduction targets, sector-specific goals, stringent green building standards, and incentives for retrofitting with energy-efficient technologies. Enforcing renewable energy integration and carbon offset mandates, along with extended producer responsibility policies, will address emissions comprehensively. Incentivizing circular economy practices and prioritizing sustainable venues for official events will encourage a shift towards responsible resource consumption. Policies promoting local, organic, and sustainable food sourcing will contribute to a greener supply chain. Standardized reporting and a green tourism certification program will ensure transparency and accountability, while dedicated funds for research, innovation, and training programs will drive sustainable practices. This comprehensive approach supports Net Zero ambitions and concurrently elevates the industry's reputation and competitiveness, establishing Malaysia as a leader in sustainable tourism.

This transition requires capacity building through staff training, implementation of energyefficient operations, and responsible procurement practices. Hospitality establishments should actively engage guests in sustainability initiatives, while investors and financial institutions play a crucial role by providing green financing and supporting low-carbon projects. At the policy level, government agencies can accelerate progress through targeted incentives and collaborative regulatory frameworks, while local communities and non-governmental organizations contribute by supporting environmental stewardship and inclusive development. Collective and coordinated engagement across these stakeholder groups is essential to reposition Malaysia's hospitality industry as a sustainable destination and a proactive contributor to global climate action.

The results indicate that although awareness of sustainability and Net Zero objectives is increasing within Malaysia's hospitality sector, significant implementation gaps remain across policy translation, operational practices, and stakeholder engagement. Sustainability efforts are largely fragmented and uneven, with most establishments prioritizing low-cost, incremental actions such as basic energy and water conservation rather than adopting systemic decarbonization strategies aligned with long-term Net Zero targets. The lack of sector-specific, standardized methods for measuring, tracking, and reporting greenhouse gas emissions, particularly in the Scope 1, Scope 2, and Scope 3 categories is a significant gap that restricts target-setting, benchmarking, and accountability, particularly for small and medium-sized businesses. Adoption of energy-efficient technologies and renewable energy solutions is further hampered by structural and financial limitations, such as high upfront investment prices and restricted access to or knowledge of green finance options. Supply chain-related emissions remain insufficiently addressed due to fragmented supplier networks, weak circular economy integration, and the lack of extended producer responsibility mechanisms. In addition, limited human capital development, weak sustainability governance, and underutilized guest engagement restrict organizational capacity for meaningful change. At the governance level, inconsistent enforcement, the absence of hospitality-specific Net Zero guidelines, and weak inter-agency coordination hinder effective policy implementation. Collectively, these findings underscore the need for an integrated, system-level transition supported by stronger regulatory alignment, standardized reporting frameworks, enhanced financial and technical support, and coordinated multi-stakeholder collaboration to enable Malaysia's hospitality industry to progress from symbolic sustainability actions toward substantive Net Zero transformation.

Figure 2. Framework for Net Zero in Hospitality Industry

The proposed Net Zero framework for Malaysia's hospitality industry adopts a multidimensional, systems-based approach encompassing governance, operational decarbonization, supply chain transformation, human capital development, and stakeholder collaboration, allowing the implementation gaps identified in this study to be mapped explicitly to its core components. Weaknesses in standardized emission measurement, reporting, and enforcement align with governance and policy misalignments, underscoring the need for hospitality-specific regulatory instruments and stronger vertical policy integration. Gaps in energy efficiency adoption, renewable energy deployment, and green retrofitting correspond to the operational decarbonization dimension, reflecting financial and capacity constraints particularly among SMEs that necessitate more accessible financing and phased transition pathways. Persistent Scope 3 emissions linked to procurement, food sourcing, and waste management highlight deficiencies in the supply chain and circular economy component, reinforcing the importance of coordinated supplier governance, extended producer responsibility, and life-cycle-based resource management. Limited training, fragmented sustainability responsibilities, and weak organizational governance map directly to human capital constraints, emphasizing the need for institutionalized sustainability competencies and leadership commitment. Finally, underutilized guest engagement and weak multi-stakeholder coordination validate the framework's stakeholder collaboration pillar, confirming that Net Zero requires collective, crosssectoral action. When taken as a whole, these identified gaps support the framework's applicability in directing managerial decision-making and integrated policy design, presenting Net Zero as a systemlevel, strategic change rather than a collection of discrete environmental projects.

5. Conclusion

This study advances the theoretical and practical discourse on Net Zero transitions in Malaysia's hospitality industry by developing a systems-based framework that integrates governance alignment, operational decarbonization, supply chain transformation, human capital development, and stakeholder collaboration. The findings demonstrate that while awareness of sustainability and Net Zero objectives is increasing, implementation remains fragmented and predominantly incremental, with limited alignment between national climate ambitions and firm-level practices. Key constraints persist in standardized emissions measurement, access to green financing, supply chain coordination, organizational capacity, and policy enforcement, underscoring the gap between intention and execution. By explicitly mapping these implementation gaps to the proposed Net Zero framework, the study highlights the necessity of moving beyond isolated initiatives toward coordinated, systemlevel transformation. Achieving Net Zero in Malaysia's hospitality sector requires robust sectorspecific governance instruments, standardized carbon accounting and reporting, enhanced financial and technical support particularly for SMEs and deeper integration of circular economy principles across supply chains. Equally critical is the development of human capital and sustainability leadership, alongside meaningful stakeholder engagement that mobilizes guests, communities, financial institutions, and policymakers in shared climate action. Theoretically, this research contributes a context-sensitive framework grounded in sustainable development and systems thinking, offering a structured lens through which Net Zero pathways in hospitality can be understood and operationalized. Practically, it provides actionable insights for policymakers and industry leaders to recalibrate strategies, strengthen institutional capacity, and align managerial decision-making with long-term climate objectives. Ultimately, the research highlights that the shift of the hospitality industry towards Net Zero is not merely an environmental necessity but also a strategic chance to improve resilience, competitiveness, and Malaysia's status as a credible leader in sustainable tourism.
