Green Strategy for Retired Electric Vehicle Battery Recycling
As the global new energy vehicle (NEV) industry rapidly expands, the disposal and recycling of end-of-life (EOL) power batteries have become imperative. Efficient closed-loop supply chain (CLSC) management, supported by well-designed regulations and strategic investments, plays a crucial role in sustainable waste power battery recycling.

Carbon Footprint Reduction through Modern Supply-Chain Measures
The worldwide Sustainable Development Goals (SDGs) for smart cities and communities focus significant attention on air quality and climate change. Technology and management can reduce fossil fuel dependence in smart cities’ energy supply chains (SC). A sustainable smart city and reduced carbon emissions require coordinated technology and management with appropriate infrastructure.

Sustainable Solutions for Small/Medium Ports
Ports are under increased pressure to reduce their negative climate and environmental impacts. Their roles and functions in transportation systems and the economy make them a key industry in promoting sustainability. In particular, small- and medium-sized ports (SMSPs) should serve as lighthouses or flagships of environmental and digital transformation, allowing access to remote locations and integrating peripheral regions.

Metal Halide Perovskites for Organic Chemical Transformations
Heterogeneous photocatalysts incorporating metal halide perovskites (MHPs) have garnered significant attention due to their remarkable attributes: strong visible-light absorption, tuneable band energy levels, rapid charge transfer, and defect tolerance. Additionally, the promising optical and electronic properties of MHP nanocrystals can be harnessed for photocatalytic applications through controlled crystal structure engineering, involving composition tuning via metal ion and halide ion variations, dimensional tuning, and surface chemistry modifications. Combination of perovskites with other materials can improve the photoinduced charge separation and charge transfer, building heterostructures with different band alignments, such as type-II, Z-scheme, and Schottky heterojunctions, which can fine-tune redox potentials of the perovskite for photocatalytic organic reactions.

Decision Support Systems Based on Gaseous Emissions
To achieve national and global air quality and climate change objectives, the agricultural sector increasingly requires dependable decision support tools for gaseous emissions at the farm level. While most decision support systems (DSSs) provide information for facilitating their use, only four are suitable for inexperienced users, and stakeholder participation in DSS development is infrequent. The dominant methodology for farm-level greenhouse gas (GHG) estimation is IPCC 2006, with quantitative models primarily used for indicators’ assessment. Scenario and contribution analyses are the prevailing decision-support approaches. Soil, crop, and fertilizer types are the most implemented non-livestock-related inputs, while climate- and feed-related costs are the least required. All DSSs assess farm-level mitigation measures, but less than half offer sustainability consultation. These tools promote environmental sustainability by evaluating mitigation strategies, disseminating farm sustainability information, and guiding sustainable farm management. Yet, challenges such as disparate estimation methods, result variations, comparison difficulties, usability concerns, steep learning curves, the lack of automation, the necessity for multiple tools, the limited integration of the results, and changing regulations hinder their wider adoption.

Polyacrylamide Polymer Membrane Used for CO2 Post-Combustion Capture
The membrane gas-capture process has been examined for several separation purposes, such as air separation, hydrogen purification, and carbon-capture methods. For the membrane CO2 removal process, several membrane materials have been studied and enhanced to meet carbon dioxide separation standards, like molecular sieves, fixed-site carriers (FSC), inorganic, and polymeric membranes.

Living on Coast in Harmony with Natural Processes
The coastal zone is a fascinating place that comprises the interface between sea and land. This interface, which is both very dynamic and sensitive, has been affected by strong urban and industrial pressures, and an increase in both traffic and recreational uses, leading to the deterioration of natural habitats and the growing instability of residential areas. Added to this disruption is ongoing climate change, which will lead to rising sea levels and increased wave action. Another problem we are increasingly concerned about is ocean pollution, which has been one of the main causes of threats to deep-water coral reef areas. The main sources of pollution include oil spills and offshore oil drilling. The effects of pollution caused by oil spills can not only seriously affect the global environmental balance of our planet but can also, on a different scale, seriously affect the economy of countries whose main resources depend heavily on the sea. Wave energy has the potential to alleviate the world's dependence on depleting fossil energy resources. With regard to coastal protection, the development of ecological solutions to preserve ecosystems and address coastal processes as an alternative to traditional coastal protection structures (seawalls, groins and breakwaters) is becoming increasingly important. These structures, generally referred to as passive measures, are usually built to alter the effects of sea waves, currents and the movement of sand along the coastline, with the aim of protecting beaches, ports and harbors.

Uncommon Production of the World
The socio-spatiality of capitalist modernity is the embodiment of pressures to eliminate common, spatially adapted institutions in the name of an allegedly more rational world demarcated by the prospect of having everything private and predisposed to be exploited. The vital element of these pressures to legitimise economic inequalities to extract more and more value from labour and nature is the phenomenon of uncommoning. This article has several interconnected goals, especially, an interpretation of the meaning and practices of uncommoningmaking use of classical, contemporary, and decolonial academic and grey literature—and a critical reflection on the frontiers of the modern world, where uncommoning is clearly the key socio-spatial driving force underpinning a deceitful democracy and providing justification for the encroachment of private properties upon the commons. This focus on the commons facilitates and radicalises the comprehension of how societies and communities deal with the allocation, use, and preservation of cherished elements of their material and immaterial reality. It can be constructively reached from the perspective of Global South societies, indigenous nations in particular, with solid experiences and knowledge of the commons. They have the outstanding intellectual and moral authority, and the main job for most is to listen, learn, and act together.

Energy Efficiency Policies for Small and Medium-sized Enterprises
The importance of small- and medium-sized enterprises (SMEs) from economic, social, and environmental point of view and the crucial role of energy efficiency (EE) are widely recognized. However, the development of effective policies and their analysis are still challenging topics, for which research is relatively scarce. The main reasons for this are the high heterogeneity of SMEs, their low energy impact compared with energy-intensive enterprises, the lack of quantitative information on the energy consumption of SMEs, and the low awareness of SMEs on energy topics. The structural paradigm change in the energy markets has underlined the importance of EE in SMEs. It is necessary to highligth the need for a good balance between economic and supportive mechanisms and the crucial role of energy audits. The analyzed contributions show that despite SMEs’ efforts to use existing EE policies, there are still important barriers to be addressed. Moreover, there is an important lack of quantitative analyses, which are necessary for the development a harmonized policy evaluation approach.
