Hydrological, meteorological, and climatological disasters have become more frequent globally (Parry et al. 2007; Cavallo and Noy 2009; CRED 2022), affecting over 3.9 billion people since 2000 and causing losses totalling USD 2.2 trillion (CRED 2020).

Climate change directly impacts the health of the human population through events such as earthquakes, flooding, heatwaves and drought, which increase the risk of injury, displacement, disruption of food supplies, infectious diseases and mental ill health (England 2024; Lenzen et al. 2020; Tennison et al. 2021; The Lancet Respiratory Medicine 2023). The impact on population health of these climate events, alongside indirect health consequences such as increased prevalence of respiratory conditions due to air pollution, places an increased burden on health services (Royal College of Physicians 2017). The environmental footprint of healthcare services contributes between 1% and 5% towards total global environmental impacts (Lenzen et al. 2020; Tennison et al. 2021). Reducing the impact of the healthcare system on climate change has the potential to benefit population health through improved air quality and diet, and increased activity levels (Mailloux et al. 2021). Due to the lack of systematic reviews which consider carbon emissions associated with the patient pathway within individual specialities, further research is needed to enable the identification and transformation of the most carbon-intensive clinical pathways, while ensuring future models of care can be delivered in a cost-effective manner without increasing emissions or compromising patient care. In 2008, the Climate Change Act set national targets for the 100% reduction of carbon emissions in England to 1990 levels by 2050 (‘Climate Change Act’ 2008). Within the United Kingdom, the National Health Service (NHS) has an important role in helping to achieve these targets, as the organisation accounts for 4% of England's carbon footprint (NHS England 2022). The UK government's Greener NHS team from NHS England asked the Exeter Policy Research Programme Evidence Review Facility to bring together and analyse research which assesses different ways carbon emissions resulting from hospital-led care can be reduced, without affecting the care patients receive in hospitals, at home and in clinics. Work focusing on identifying and delivering interventions to reduce carbon emissions within known carbon hotspots, such as NHS estates and facilities, travel and transport, supply chain, and certain medicines and medical and anaesthetic gases that have high global warming potential is already underway, alongside examining the effectiveness of different models of care delivery across all specialities (NHS England 2022; NHS Shared Business Services 2022). Evidence focusing on the effectiveness of interventions in reducing carbon emissions within secondary healthcare would be a useful complement to this work. An approach which considers the patient pathway may be beneficial in identifying interventions which consider wider healthcare systems and thus have a meaningful impact on reducing carbon emissions.

Guided by what has been achieved in psychology and criminology, scholars from the field of preventing violent extremism (PVE) have tried to import key lessons from violence risk assessment and management, while bearing in mind the idiosyncrasies of their particular field. However, risk tools that have been developed in the PVE space are relatively recent, and questions remain as to their level of psychometric validation. Namely, do these tools consistently and accurately assess risk of violent extremist acting out? To answer this question, we systematically reviewed evidence on the reliability and validity of violent extremism risk tools. The main objective of this review was to gather, critically appraise, and synthesize evidence regarding the appropriateness and utility of such tools, as validated with specific populations and contexts. Searches covered studies published up to December 31, 2021. They were performed in English and German across 17 databases, 45 repositories, Google, other literature reviews on violent extremism risk assessment, and references of included studies. Studies in all languages were eligible for inclusion in the review. We included studies with primary data resulting from the quantitative examination of the reliability and validity of tools used to assess the risk of violent extremism. Only tools usable by practitioners and intended to assess an individual's risk were eligible. We did not impose any restrictions on study design, type, method, or population. We followed standard methodological procedures outlined by the Campbell Collaboration for data extraction and analysis. Risk of bias was assessed using a modified version of the COSMIN checklist, and data were synthesized through meta-analysis when possible. Otherwise, narrative synthesis was used to aggregate the results. Among the 10,859 records found, 19 manuscripts comprising 20 eligible studies were included in the review. These studies focused on the Terrorist Radicalization Assessment Protocol (TRAP-18), the Extremism Risk Guidance Factors (ERG22+), the Multi-Level Guidelines (MLG-V2), the Identifying Vulnerable People guidance (IVP guidance), and the Violent Extremism Risk Assessment (VERA)—all structured professional judgment tools—as well as <i>Der Screener—Islamismus</i>, an actuarial scale.

However, in the words of the head of the World Bank's Development Impact Group, DIME, ‘Dissemination is dead’.<sup>1</sup> That is, traditional dissemination pathways—academic publications, conference presentations, and even policy briefs—are insufficient for achieving meaningful policy uptake. No matter how rigorous or relevant, research alone does not usually translate into policy impact without deliberate, structured mechanisms to bridge the gap between evidence generation and decision-making. The recognition of this fact has resulted in the growth of knowledge translation as what has been called the fourth wave of the evidence revolution (White <span>2019</span>).</p><p>Knowledge translation is ‘the exchange, synthesis, and effective communication of reliable and relevant research results. The focus is on promoting interaction among the producers and users of research, removing the barriers to research use, and tailoring information to different target audiences so that effective interventions are used more widely’ (World Health Organization <span>2004</span>). There are various approaches to knowledge brokering. These include direct interaction between researchers and decision-makers in interpreting and using the findings, in-house knowledge brokers, creating a ‘helpdesk’ function, or using an independent rapid review service.</p><p>The approach we discuss here is online evidence-based decision-making products (EBDMPs), which summarize research findings in accessible forms without requiring the user to read the underlying research papers or reports.

The objectives are as follows. Our review will exclusively emphasize quantitative evidence from experimental studies, identifying the important factors and providing comprehensive and in-depth recommendations, with a primary focus on identifying the effective communication and marketing strategies that have been evaluated. The findings of the study focusing on consumers' acceptance will provide valuable insight for policymakers to combat the food waste issue. The research questions are as follows: RQ1: What are the key factors influencing consumer acceptance in experimental studies on upcycled foods?
