1. Introduction

The topic of research, known as sustainable operations management (SOM), centres around the incorporation of sustainability principles into the management of operations inside organizations. The primary objective of the SOM approach is to mitigate adverse environmental and social consequences associated with operational activities, while concurrently maximising economic advantages. In recent years, there has been a notable increase in interest towards this topic, mostly driven by the heightened recognition of the influence that corporate activities exert on both the environment and society. The concept of SOM encompasses the integration of sustainable practices across various domains, including supply chain management, product design, energy management, waste management, and transportation. The use of SOM practices has the potential to yield financial benefits through cost reduction, enhance the reputation of a business, and enhance its competitive advantage ^[1]^[2]. An integral part of SOM is waste management, which sets the foundation of a sustainable circular economy. The environmental impact of waste products, such as industrial and municipal garbage, is substantial because of their capacity to cause contamination and the inefficient use of resources. The scope of SOM should include the implementation of methods aimed at effectively managing and repurposing waste products to mitigate their impact on the environment. The recent literature on waste management includes the application of innovation technology. The authors of ^[3] explore a plethora of various applications of waste materials, such as their use in energy production, H₂ storage, catalysis, adsorption, and CO₂ capture. Integrating findings from this paper into the proposed SOM framework can help organizations identify sustainable ways to repurpose waste materials for energy generation, carbon capture, and more. Moreover, paper ^[4] examines how waste materials can also find applications in the pharmaceutical industry, such as drug delivery and detection. Incorporating insights from this paper allows firms to explore sustainable alternatives in drug manufacturing and delivery, potentially reducing the environmental impact of pharmaceutical operations, and finally, ref. ^[5] discusses the potential of waste material (orange peels) in cancer therapy. By leveraging waste materials for solar cell production, firms can contribute to renewable energy generation while reducing waste disposal burdens.

Climate neutrality in Europe has been envisioned as a critical objective, with decarbonization strategies being extensively pursued to achieve this goal ^[6]. Simultaneously, innovative wastewater treatment methods, such as MEUF, have been employed to address environmental concerns. Through the amalgamation of Europe’s climate neutrality vision, decarbonization efforts, and the implementation of cutting-edge technologies like MEUF, a sustainable future is being forged for the region with different strategies. By intertwining these essential topics, a comprehensive understanding of the multifaceted approach to environmental preservation and climate action can be gleaned. These strides towards sustainability are bolstered by policy frameworks and regulations that incentivize green innovation and penalize environmental degradation. In the energy sector, the transition to renewable energy sources is paramount. Solar, wind, and geothermal energy are being harnessed at an unprecedented scale, replacing fossil fuels and reducing greenhouse gas emissions significantly. The modernization of energy infrastructure, including smart grids and energy storage solutions, facilitates the integration of these renewable sources, ensuring energy reliability and security. Public awareness and engagement are also integral to this journey towards climate neutrality. Educational initiatives, public campaigns, and community involvement activities are vital in fostering a culture of environmental responsibility and sustainability. Citizens are empowered with knowledge and tools to contribute to climate action, enhancing the collective impact of individual efforts. In the context of wastewater management, advancements in technologies like MEUF signify a revolution in pollution control and resource recovery. As Europe marches towards achieving climate neutrality, the synergies between various sectors—from energy to waste management and from policymaking to public participation—are becoming increasingly evident. Each element is a piece of a complex puzzle, and their effective integration is indicative of the comprehensive strategy required to address the intricate challenges posed by climate change and environmental degradation, a summary of measures and strategies is presented at Table 1. The collective efforts, innovations, and policies are weaving a tapestry of resilience, sustainability, and climate neutrality that is expected to define Europe’s future.

2. Advancing towards Europe’s Climate Neutrality Ambitions

Progress towards Europe’s climate neutrality ambitions has been steadily advanced through the implementation of comprehensive decarbonization strategies. The adoption of innovative technologies, such as MEUF, that is analysed at a later chapter has been promoted to ensure effective wastewater treatment and to address environmental concerns. A sustainable future for the region has been facilitated by the harmonious integration of these efforts, thereby enabling a multi-faceted approach to environmental preservation and climate action. Consequently, a deeper understanding of the intricate interplay between climate neutrality, decarbonization, and cutting-edge technologies has been provided, highlighting the commitment of European nations to achieving a sustainable and environmentally responsible future for the geographical region ^[6]^[7].

3. Decarbonization Strategies in Key Sectors

Decarbonization strategies in key sectors have been increasingly prioritized as a crucial component of Europe’s climate neutrality efforts. In the energy sector, a significant transition to renewable sources has been witnessed, while the reliance on fossil fuels has been gradually diminished. The transportation industry has been revolutionized by the widespread adoption of electric vehicles, and improvements in public transport systems have been made to reduce the carbon footprint. Industrial processes have been reevaluated and optimized to minimize greenhouse gas emissions, and sustainable practices have been integrated into agriculture and land use. Technological innovations and policy reforms are synergistically driving this transformation, enhancing efficiency and sustainability across sectors ^[8]. Collaboration among governments, businesses, and civil society is fostering a collective approach, amplifying the impact of individual contributions. As a result, the transition towards a low-carbon economy has been accelerated, and the ambition of achieving climate neutrality in Europe has been brought closer to realization.

3.1. Building Sector

Significant steps have been made in the building sector as part of the concerted efforts towards achieving climate neutrality in Europe. Energy-efficient practices and the use of eco-friendly materials have been increasingly prioritized, leading to the construction of greener, more sustainable buildings ^[9]; additionally, the construction sector is placing more emphasis on optimising energy processes in infrastructure construction using the concepts of embodied energy and lifecycle assessment. Embodied energy is the complete amount of energy needed to manufacture a product, whereas lifecycle assessment is a technique employed to examine the environmental consequences linked to every phase of a product’s existence. Exploration is underway to utilise Building Information Modelling (BIM) software for the purpose of optimising energy processes. Furthermore, EU energy policy places a high level of importance on promoting energy efficiency. The civil sector, encompassing both residential and tertiary buildings, presents significant opportunities for enhancing energy efficiency. The implementation of policy instruments, such as tax deductions and economic incentives, has proven to be successful in generating significant opportunities for energy savings by addressing inefficiencies in the civil sector ^[10]. The adoption of passive house designs and the incorporation of renewable energy sources, such as solar panels and geothermal heating systems, have been embraced across the region. Retrofitting older buildings with improved insulation and energy-efficient technologies has been widely implemented to reduce overall energy consumption and greenhouse gas emissions attributable to the built environment ^[11].

In addition, building certifications promoting sustainability, like LEED and BREEAM, have gained prominence, setting stringent standards for environmental performance, and encouraging the adoption of green building practices. These certifications not only validate the sustainability credentials of a building but also enhance its value, fostering a market transformation towards sustainability ^[12]. The European Union (EU) has established a standardized set of fundamental sustainability indicators, called Level (s), for office and residential buildings. This framework aims to establish a consistent structure for certifying the sustainability of buildings throughout all EU member countries. This framework is utilized for the purpose of comparing the predominant Green Building Rating Systems (GBRSs) in the European Union, which encompass BREEAM, “Deutsche Gesellschaft für Nachhaltiges Bauen (DGNB)”, “Haute Qualité Environnementale (HQE)”, and LEED ^[13]. The cumulative impact of these innovations and initiatives is profound. The building sector is transitioning from being a significant contributor to environmental degradation to becoming a catalyst for sustainability and climate action. The holistic approach, encompassing technology, policy, and societal engagement, is paving the way for a future where buildings are not only structures for habitation and work but also embodiments of ecological and social values.

3.2. Energy Sector

Identified as a crucial component for pursuing climate neutrality in Europe, the energy sector’s significant greenhouse gas emissions are attributed to energy production and consumption. Nevertheless, there has been a gradual reduction in carbon emissions from energy systems in Europe, primarily due to the substitution of fuels and the growing adoption of renewable energy sources. This phenomenon has been notably apparent in the industry, buildings, and transport sectors ^[14]. The exploration and implementation of diverse low-carbon, renewable energy sources across Europe, for replacing fossil fuels, have resulted in a considerable carbon footprint reduction ^[15]. Intensified efforts for energy efficiency enhancement, prevention of losses ^[16] and conservation promotion have centred on energy consumption optimization in various sectors like electric vehicle charging ^[17]. Electric vehicle charging integration with the electricity grid is a crucial component of Europe’s 2050 low-carbon plan. This approach promotes the use of sustainable energy sources and aids in mitigating the release of greenhouse gases. Innovative technologies for improved renewable energy integration into grids, investment encouragement in research and development, and the promotion of breakthrough energy technologies contribute to resilience, sustainability, economic growth, and job creation, underlining a green economy’s potential ^[18]. The utilisation of renewable energy has a substantial influence on reshaping the global fuel and energy distribution. Promoting the advancement of renewable energy and a sustainable economy with reduced carbon emissions is a key objective of contemporary energy and international economic policies in numerous nations; for example, wind energy in Europe has been empirically proven to have a favourable influence ^[19]. The efforts to incorporate renewable energy sources (RES) into power networks, specifically transmission grids, are a primary area of emphasis. This encompasses the use of cutting-edge materials, novel electrical components, sophisticated electronic devices, automated control systems, intelligent technologies, and innovative management mechanisms. The formulation of comprehensive policies and regulatory frameworks has further accelerated this transition, ensuring that sustainable energy practices are not only technologically viable but also legislatively supported and economically incentivized.

3.3. Industrial Sector

The industrial sector has been recognized as a key contributor to greenhouse gas emissions, and as such, it is imperative that significant decarbonization efforts are focused on this domain. Various measures have been adopted to reduce the environmental impact of industrial processes, including optimizing energy consumption, using renewable energy sources, and implementing innovative waste management techniques. Additionally, the adoption of circular economy principles has been encouraged, in which resource efficiency and waste reduction are prioritized, thereby promoting sustainable industrial practices ^[20]. Developing economies such as Nigeria have examined the application of circular economy principles in the management of industrial solid waste. These concepts promote a regenerative approach to managing natural resources, which is in contrast to a linear strategy that is not sustainable because of the limited supply of raw resources for production and the resulting environmental degradation ^[21].

In recent years, the application of advanced technologies, such as MEUF, has been widely embraced in the industrial sector to address wastewater treatment challenges. By utilizing these cutting-edge methods, industries have been able to reduce their environmental footprint and support Europe’s climate neutrality ambitions. Furthermore, the collaboration between the public and private sectors has been instrumental in driving research and development in environmentally friendly technologies, leading to the creation of innovative solutions that support a cleaner and more sustainable industrial sector. A relatively recent case study undertaken at Volvo CE, a multinational corporation, emphasized the significance of effective leadership, prompt implementation, and cultural change at the organizational level in attaining sustainable energy management ^[22]. Finally, another dynamic model, the multi-objective dynamic model developed for the industrial sector context is a tool designed to analyse all variables that impact the overall energy consumption in the sector. This model considers multiple factors that impact energy usage, beginning with the extraction of raw materials, their transportation to manufacturers, the grid network, and ultimately the delivery of the final product to consumers, as well as the disposal or recycling of used products. The model is created to comprehensively account for all relevant elements concurrently, with a particular emphasis on the insufficiency of solely implementing some ways, such as solar panels, while disregarding other crucial factors like end-user considerations and life cycle analysis ^[23]. As Europe moves towards achieving its climate goals, the continued commitment to decarbonization within the industrial sector remains a crucial component of the overall strategy.

4. Digitalization as a Catalyst for Decarbonization Efforts

Digitalization’s role as a catalyst for decarbonization efforts across various sectors and businesses sizes in Europe is increasingly recognized ^[24]. Advanced technologies like artificial intelligence, big data, and IoT have resulted in substantial improvements in energy efficiency, resource management, and greenhouse gas emission reduction. Enhanced monitoring and control over energy consumption patterns have been facilitated, and processes have been optimized. A key enabler of Europe’s low-carbon economy transition, digitalization accelerates the transition from fossil fuels to renewables, contributes to reducing Europe’s carbon footprint, and encourages the adoption of electric vehicles through smart charging infrastructure. Industrial transformation through digitalization results in more sustainable practices, promotes the circular economy, minimizes energy consumption and waste, aligning with Europe’s decarbonization and climate neutrality goals. Digitalization fosters sustainable development and accelerates Europe’s transition towards a low-carbon future.
