This study, part of an R&D project with Dutch tour operators, assessed Dutch consumer preferences towards a carbon label for holiday trips. A general survey (n = 504) assessed the perceived importance of a CO 2 label to consumers. To determine the preferred design, two focus groups (n = 15) followed by a panel study (n = 1246) were performed. Finally, a pilot study (n = 100) assessed potential effects of the label on attitude and booking intention. The general survey's results indicate that a carbon label could impact on the travel choice of some Dutch travellers, when label information is explicit, understandable and simply designed. The focus groups in combination with the panel study showed that Dutch consumers prefer a recognisable carbon label, similar to the EU energy label. The pilot study revealed that consumers' attitudes increased significantly, but that intention to book was not significantly affected for the group that was shown the carbon label. These findings contribute to understanding consumer attitudes towards tourism eco and carbon labels, and their content and design. Implementation of a carbon label for tour packages still requires a number of barriers to be resolved. Sustainability remains a low priority during holiday decision-making.

This letter to the editor argues that the assumption of a single value for the acetate recovery factor in carbon-13 stable isotope research for different individuals, can lead to significant errors in the outcomes of substrate utilization measurements.

Energy policies are vital tools used by countries to regulate economic and social development as well as guarantee national security. To address the problems of fragmented policy objectives, conflicting tools, and overlapping initiatives, the internal logic and evolutionary trends of energy policies must be explored using the policy content. This study uses 38,277 energy policies as a database and summarizes the four energy policy objectives: clean, low-carbon, safe, and efficient. Using the TextCNN model to classify and deconstruct policies, the LDA + Word2vec theme conceptualization and similarity calculations were compared with the EISMD evolution framework to determine the energy policy theme evolution path. Results indicate that the density of energy policies has increased. Policies have become more comprehensive, barriers between objectives have gradually been broken, and low-carbon objectives have been strengthened. The evolution types are more diversified, evolution paths are more complicated, and the evolution types are often related to technology, industry, and market maturity. Traditional energy themes evolve through inheritance and merger; emerging technology and industry themes evolve through innovation, inheritance, and splitting. Moreover, this study provides a replicable analytical framework for the study of policy evolution in other sectors and evidence for optimizing energy policy design

In het vorige blog kwam de term ‘greenwashing’ voor en werd ik nieuwsgierig of organisaties inderdaad zo groen zijn als ze beweren in bijvoorbeeld hun jaarverslagen. Greenwashing staat voor “het zich groener of maatschappelijk verantwoorder voordoen dan een bedrijf of organisatie daadwerkelijk is”. Het kernproces van het bedrijf is dan bijvoorbeeld nog niet aangepast. Bedrijven noemen hun product ‘natuurlijk’, terwijl er misschien maar één natuurlijk ingrediënt in voorkomt. Op die manier kunnen ze mooi meelopen met de groene trend, zonder daadwerkelijk te voldoen aan milieueisen. Het is meer een likje groene verf. Zijn er middelen die ons kunnen helpen bij het vormen van een kritische houding?

Dealing with and maintaining high-quality standards in the design and construction phases is challenging, especially for on-site construction. Issues like improper implementation of building components and poor communication can widen the gap between design specifications and actual conditions. To prevent this, particularly for energy-efficient buildings, it is vital to develop resilient, sustainable strategies. These should optimize resource use, minimize environmental impact, and enhance livability, contributing to carbon neutrality by 2050 and climate change mitigation. Traditional post-occupancy evaluations, which identify defects after construction, are impractical for addressing energy performance gaps. A new, real-time inspection approach is necessary throughout the construction process. This paper suggests an innovative guideline for prefabricated buildings, emphasizing digital ‘self-instruction’ and ‘self-inspection’. These procedures ensure activities impacting quality adhere to specific instructions, drawings, and 3D models, incorporating the relevant acceptance criteria to verify completion. This methodology, promoting alignment with planned energy-efficient features, is supported by BIM-based software and Augmented Reality (AR) tools, embodying Industry 4.0 principles. BIM (Building Information Modeling) and AR bridge the gap between virtual design and actual construction, improving stakeholder communication and enabling real-time monitoring and adjustments. This integration fosters accuracy and efficiency, which are key for energy-efficient and nearly zero-energy buildings, marking a shift towards a more precise, collaborative, and environmentally sensible construction industry.

During crime scene investigations, numerous traces are secured and may be used as evidence for the evaluation of source and/or activity level propositions. The rapid chemical analysis of a biological trace enables the identification of body fluids and can provide significant donor profiling information, including age, sex, drug abuse, and lifestyle. Such information can be used to provide new leads, exclude from, or restrict the list of possible suspects during the investigative phase. This paper reviews the state-of-the-art labelling techniques to identify the most suitable visual enhancer to be implemented in a lateral flow immunoassay setup for the purpose of trace identification and/or donor profiling. Upon comparison, and with reference to the strengths and limitations of each label, the simplistic one-step analysis of noncompetitive lateral flow immunoassay (LFA) together with the implementation of carbon nanoparticles (CNPs) as visual enhancers is proposed for a sensitive, accurate, and reproducible in situ trace analysis. This approach is versatile and stable over different environmental conditions and external stimuli. The findings of the present comparative analysis may have important implications for future forensic practice. The selection of an appropriate enhancer is crucial for a well-designed LFA that can be implemented at the crime scene for a time- and cost-efficient investigation.
