The construction sector, by its very nature complex and multifaceted, is constantly looking for new methods capable of improving the management system of a project, increasing the efficiency and productivity of some operational phases related to careful planning of the works. To date, the aspects related to sustainability are attributable to the materials used and energy consumption of buildings, but the construction phase of a building is the most harmful moment for the environment. This research has as its primary objective the in-depth study of one of the salient aspects of Facility Management: the guarantee of and compliance with environmental standards, in particular during the construction phase. In more detail, the aspect of the acquisition of methodologies for the environmental management of the recovery site will be explored through compliance with the so-called DNSH (Do Not Significant Harm) Principle, introduced by the Recovery and Resilience Facility (RRF), an economic instrument that supports the national recovery and resilience plans (PNRR). Environmental management will be explored through the creation of an environmental sustainability protocol applied to the construction phase and drawn up on the basis of current environmental legislation. The protocol was validated with the application of the ACS (Sustainable Construction Site Certificate) in a case study located in Italy, Palazzo Lazzaro, which is located in the post-earthquake reconstruction areas, in particular, in Fossa (AQ).

This study presents an innovative financial model that integrates the debt-for-climate swap mechanism with Article 6 of the Paris Agreement, specifically designed to support Africa’s transition to clean energy. The model connects debt-for-climate swaps with the creation of internationally transferred mitigation outcomes (ITMOs), offering mutual benefits for both debtor and creditor nations. This approach aims to improve the debt sustainability of African countries while strengthening their climate resilience by combining Article 6 of the Paris Agreement with Official Development Assistance (ODA). Additionally, this model aligns with key Sustainable Development Goals (SDGs), including SDG 7 (Affordable and Clean Energy), SDG 13 (Climate Action), and SDG 17 (Partnerships for the Goals). Furthermore, the study proposes a restructuring of existing environmental safeguards by incorporating the “Do No Significant Harm” (DNSH) criteria and environmental contribution indicators to ensure alignment with the minimum safeguards mandated by Article 6 and international development standards. Through quantitative analysis, our findings indicate that the proposed debt-for-climate swap model could significantly contribute to Africa’s clean energy transition, address the region’s external debt challenges, and enhance climate resilience.

Effective weed management faces increasing legislative restrictions for the use of herbicides due to their toxicity and environmental persistence. In addition, the linear increase in resistant weeds threatens to render authorized herbicides useless. In a post-herbicide era, under the IWM strategy, allelopathy can play a relevant role since many plants can produce a variety of allelochemicals with different structures and modes of action, capable of inhibiting the germination and growth of different weed species. Inspired by green manuring with cover crops, the use of allelopathic biomass from weeds, invasive species, residues of forestry plantations, and other abundant wild plants has some advantages over green manures grown in situ or other alternatives such as applying plant extracts or essential oils. Beyond the ecosystem services provided by green manures, the potential use of allelopathic biomass offers extra opportunities for the science and practice of holistically integrated weed management because (i) the investment of resources and time for producing cover crops would be alleviated, and (ii), new use of agroforestry residues and a sink for harmful weed biomass is provided. In this review, we compile the current knowledge of those allelopathic species whose biomass, used as soil amendment, effectively controlled weeds. In addition, the complex allelopathic processes underlying the effectiveness of cover crops and allelopathic biomass used as green manures for weed control are revisited. Full article

The deployment of automated vehicles (AVs) has the potential to disrupt and fundamentally transform urban transportation. As their implementation becomes imminent on cities’ streets, it is of great concern that no comprehensive strategies have been formulated to effectively manage and mitigate their potential negative impacts, particularly with respect to the components of the do no significant harm (DNSH) framework recently introduced in the EU taxonomy. The methodology employed comprises three steps: (i) An extensive literature review on the impact of AVs on the DNSH components; (ii) exploration of designing a coherent pro-active vision by integrating measures identified in the literature as key elements to mitigate the harm; and (iii) an interdisciplinary focus group (FG) to verify whether the impacts of AVs and potential mitigation measures for Bucharest are similar to those identified by the literature and integrated into the pro-active vision. The results suggest that while there are commonalities, variations exist in focus and perspective, underscoring the necessity of examining the mitigation measures encompassed in the vision through additional focus groups conducted in different cities.

ESG frameworks have progressively become central in economic and policy choices. This is why it is of utmost importance to build a shared and accepted framework to define what we really mean by ESG overcoming the “minimalist” Do Not Significantly Harm (DNSH) principle and moving toward the full achievement of the more ambitious substantial contribution (SC) principle, oriented to the maximization of the social and environmental impact of value creation. To move forward in this direction, our work proposes a relational approach for the assessment of ESG factors focusing in particular on the social pillar. Our conceptual and theoretical proposal argues that, in order to increase the value of that pillar, it is necessary to assess both the internal and external relationships of the firm from an impact perspective, improving at the same time the multidimensional well-being of workers and the capacity to create sustainable development in the local community. The main factors companies should consider to achieve these goals are related to the domains of sense of community, empowerment, good practices of mutual aid and degree of participation at individual, team, organization, and territorial levels that can trigger gift giving, reciprocity and trust, overcoming standard social dilemmas and producing superadditive outcomes together with high social and environmental impact. Starting from these elements, this work proposes a set of indicators and metrics, based on an original methodology to measure and assess the commitment of a firm to increasing social factors. This methodology is particularly suitable for SMEs and start-up companies. Full article

In this study novel immunoconjugates were designed, synthesized and then used to develop a rapid, specific and sensitive indirect ELISA method to directly detect residues of 3,5-dinitrosalicyclic acid hydrazide (DNSH), a toxic metabolite of nifursol present in chicken tissues. The hapten DNSHA was first designed and used to covalently couple to BSA to form an immunogen which was immunized to rabbits to produce a polyclonal antibody against DNSH. Furthermore, a novel 3,5-dinitrosalicylic acidovalbumin (DNSA-OVA) immunoconjugate structurally different from DNSHA-OVA was designed and used as a “substructural coating antigen” to improve the sensitivity of an indirect ELISA analysis for a direct DNSH detection. Based on the “substructural coating antigen” concept, an optimized indirect ELISA method was established that exhibited good specificity and high sensitivity for detecting DNSH, with a cross-reactivity of less than 0.1% (excluding the parent compound nifursol), IC₅₀ of 0.217 nmol/mL and detection limit of 0.018 nmol/mL. Finally, a simple and efficient analysis of DNSH samples in chicken tissues showed that the average recovery rate of the indirect ELISA analysis was 82.3%, with the average coefficient of variation 15.9%. Thus, the developed indirect ELISA method exhibited the potential for a rapid detection of DNSH residues in tissue. Full article
