Summary: The study finds that winning public procurement awards with environmental selection criteria significantly increases the probability of firms introducing more environmentally friendly products, especially for small and medium-sized firms, with no significant effect for larger firms. There is also no statistically significant effect on the introduction of more environmentally friendly processes.

Summary: Green Public Procurement (GPP) is an alternative for public agencies to purchase goods and services with reduced environmental impact. This study analyzed the inclusion of environmental criteria in public works procurement and found that most projects only include environmental criteria in the technical specifications and contract performance clauses. However, the study provides guidance for procurement professionals and researchers on how to incorporate environmental criteria in the procurement process based on infrastructure type and project characteristics, which are necessary for governments interested in improving their performance towards the Sustainable Development Goals.

Summary: This study investigates the potential influence of organisational responses to conflicting institutional demands on barriers to environmental performance (EP) monitoring of government green procurement (GGP) in Malaysia. The findings suggest that policy irregularities, knowledge asymmetry, and communication gaps are the key challenges hindering EP monitoring of GGP in Malaysia. The practical implications include the need for policymakers to have knowledge of barriers in order to design the monitoring process effectively and to increase transparency and accountability in green procurement.

Summary: Sustainable public procurement (SPP) in China is a hierarchical and centralized multi-level system driven by legal and policy initiatives, social benefits, and public body commitments. There is untapped potential for more SPP in China, but barriers exist at the operational level. This research recommends a reform of SPP by involving state-owned enterprises and infrastructure projects in a different approach.

Summary: Green public procurement plays a vital role in reducing the environmental impact of societies. This paper presents a method for developing green procurement tools based on life-cycle assessment data and national environmental objectives. The method was applied to develop a tool for green procurement of public transport services in Sweden, showing that certain fuel systems align well with environmental objectives while others perform worse.

Summary: Mission-oriented approaches, such as green public procurement (GPP), are popular solutions for governments to address sustainability challenges. This paper investigates the use of voluntary standards in GPP and missions-oriented innovation systems (MIS) for sustainable urban development (SUD) at the municipal level. The study conceptually formulates sustainability missions and analyzes the roles of voluntary standards and stakeholders in achieving these missions.

Summary: Green public procurement (GPP) is widely used as a public administration tool for achieving sustainability outcomes, with significant cross-country differences in adoption. Factors such as more developed countries, larger government size, better governance, and larger contracts are positively associated with GPP adoption. Collaborative procurement between contracting authorities increases the likelihood of GPP adoption.

Summary: This study examines the influence of internal commitment and external pressures on green purchasing in local governments. The findings suggest that internal commitment plays a more significant role, and earlier stages of green public procurement institutionalization are more susceptible to external influence.

Summary: In the context of sustainable neighborhood developments, the neighborhood scale is suggested as a successful scale to realize cross-sector, inter-organizational collaborations, but the complexity of multifaceted goals and resulting interdependencies challenges the promise of sustainable transition, creating a gap between what is promised as sustainable neighborhoods and what is actually delivered.

Summary: This study explores the relationship between GPP market pressure and firm's environmental certification practice using institutional theory and upper echelons theory. It finds that GPP market pressure is positively associated with environmental certification practice, and top management support partially mediates this relationship. The study provides new insights and practical implications for firm managers and government administrators.

Summary: The decision-making of Czech public procurers is affected by the trade-off between stewardship and administrative compliance, resulting in a prioritization of contract criterion over ecological criteria. Public procurers possess a stewardship motivation towards GPP but also seek to avoid administrative risks associated with its implementation.

Summary: This study examines the impact of ideological alignment between politicians and bureaucrats on turnover and performance. It finds significant partisan cycles and turnover among political appointees, while no political cycles exist in the civil service. A considerable proportion of bureaucrats are ideologically misaligned with their political leaders. The study also reveals that procurement contracts overseen by misaligned officers experience greater cost overruns and delays.

Summary: This study evaluated the effect of alternative filtering materials and bed aeration on the retention of nutrients and fecal bacteria in woodchip bedded stand-off pads for cows. The results showed that the alternative biofilters were more efficient in removing COD, SS, TN, and NO3-N, while conventional biofilters were more efficient for PO4-P removal. Aeration did not have a significant effect under the tested temperature conditions.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: In this study, an electron beam excitation multi-wavelength ultraviolet (EBE-MW-UV) system was established and found to have significantly higher microbial inactivation effects compared to single-wavelength UV-LEDs in water. Mechanism analysis revealed that EBE-MW-UV damaged microbial DNA and proteins, and generated additional reactive oxygen species, leading to microbial inactivation.

Summary: This study focuses on the development of an air-lift bio-electrochemical reactor (ALBER) with a continuous feeding regime to enhance nitrogen removal from synthetic wastewater. The effect of temperature, hydraulic retention time (HRT), N -NH+4 /TN ratio, and current density on the reactor performance was investigated, and the ALBER achieved a maximum TN removal of 73%. The results suggest that the ALBER has potential for treating industrial wastewater at low temperatures.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
