The document highlights that climate change adaptation in the Basque Country requires fluid dialogue across society and can be achieved through changes in habits and lifestyles. It notes that increased exposure to the natural environment has a positive impact on health and well-being, and that specific adaptation measures can enhance overall population resilience.

The document argues that cities are becoming primary actors in achieving climate mitigation and adaptation goals. It emphasizes that science provides essential support to local policymakers through first-hand information and the application of ad hoc methodologies. Case studies presented in the work demonstrate diverse opportunities for collaboration between scientific research and municipal-level policy, suggesting that the urban scale is an effective level for establishing multi-level links between these fields.

The policy brief highlights the critical role of cities in achieving climate change containment and adaptation goals. It asserts that science can assist local policymakers by providing high-quality information and developing specialized methodologies. The authors argue that the urban scale is an ideal environment for strengthening the link between scientific research and policy implementation.

The document highlights the role of science in achieving urban climate objectives under the Basque Declaration, while noting that divergent interests between science and policy, as well as the difficulty of balancing scientific rigor with practical applicability, present both challenges and opportunities.

The document examines sea level fluctuations in the Basque Country across geological timescales, noting a significant acceleration in the 20th century compared to the previous 7,000 years. It contrasts process-based and semi-empirical global models to project future rises, estimating that the Basque coast could see an increase of 41-57 cm by 2100 depending on the emissions scenario.

The document outlines various BC3 research initiatives aimed at improving urban resilience and sustainability. Key examples include flood-risk modeling in Bilbao and Zurich, heat-health warning system evaluations in Madrid, and the socio-economic analysis of energy efficiency plans. It emphasizes the necessity of science-policy collaboration to create cost-efficient, data-driven urban interventions.

The document outlines expected climate impacts in the Basque Country, including rising temperatures, sea-level rise, and altered precipitation, which threaten public health through heat waves, flooding, and increased pollutants. It identifies 26 adaptation measures, highlighting the cost-effectiveness and co-benefits of ecosystem-based solutions like Sustainable Urban Drainage Systems (SUDS) and behavioral changes in transport.

The document examines the intersection of science and urban policy, identifying that while research can provide robust data to validate decision-making and increase citizen trust, significant gaps exist due to differing timeframes, technical languages, and motivations. It argues that co-creating solutions and bridging the gap between researchers and practitioners is essential for the successful implementation of the Basque Declaration's sustainability goals.

The document presents findings from a study of scientists at the University of the Basque Country (UPV-EHU) and the Basic and Excellence Research Centres (BERC) network. It finds that scientists primarily view science communication as a social responsibility and duty, with a strong preference for face-to-face interactions. The study highlights that scientists believe the success of communication depends on the benefit to the audience and is largely within the speaker's control through adaptability and preparation. The authors suggest that these scientists already embody many of the goals of Responsible Research and Innovation (RRI), though they note that real-world constraints like time and resources may impact these ideals.

The document argues that agricultural management is overly driven by food production, leading to a decline in the ecosystems it depends on. It advocates for an ecosystem-based approach to food security and introduces semantic meta-modelling as a tool to integrate various models and quantify trade-offs between crop yields and regulating services like water quality and climate regulation. Using a case study in the Basque Country, the authors demonstrate that informed farming practices, such as adjusting manure application and reducing tillage, can significantly reduce emissions and nitrate leaching without necessarily compromising winter wheat yields.

The document evaluates the environmental sustainability of first-generation biofuels produced in the Basque Country using an innovative methodology that integrates the SIMSNIC agronomic model with life cycle analysis. The study focuses on bioethanol from wheat and biodiesel from rapeseed in the La Llanada Alavesa area. It finds that while biofuels are more energy efficient than fossil fuels, meeting the EU's mandatory 35% greenhouse gas (GHG) reduction target is unlikely under current mineral fertilisation conditions, particularly in nitrate-vulnerable areas. Organic fertilisation increases the likelihood of meeting GHG targets but exacerbates water contamination, soil acidification, and land-use competition. The authors conclude that the agricultural stage, specifically nitrogen fertilisation and climatology, is the primary driver of the carbon footprint due to nitrous oxide emissions.

The research paper investigates the effectiveness of Bonus-Malus schemes for promoting energy-efficient household appliances in Spain, specifically focusing on dishwashers, refrigerators, and washing machines. The authors develop a methodology to optimize the combination of taxes and subsidies to minimize dead weight loss (DWL) while meeting specific policy goals such as emission reductions or budget neutrality. The study finds that while simple subsidies can lead to welfare loss and increased energy bills due to a higher total number of appliances, a combined tax-subsidy approach can more effectively shift the market toward efficient goods. For instance, achieving a 10% emission reduction for dishwashers would be most effective by taxing both labelled and non-labelled goods, though this results in a significant reduction in the total number of appliances. Conversely, budget-neutral schemes can increase the share of efficient appliances but may inadvertently increase total energy consumption if the increase in efficient units outweighs the reduction in inefficient ones.

The document emphasizes that urban sustainability is not merely a technological challenge but involves power relations, culture, and social values. It advocates for the use of participatory methods to integrate the 'cognitive dimension'—the knowledge, perceptions, and values of diverse stakeholders—to identify barriers and opportunities in energy transitions. Using a Fuzzy Cognitive Mapping (FCM) study in Bilbao, the authors demonstrate that social initiatives and changes in lifestyle yield superior results in reducing emissions and improving quality of life compared to purely economic or institutional measures.

The report introduces 'governAbilities' as the nexus of sustainability, accountability, and adaptability, arguing that these three operational areas are essential for governments to maintain a 'social licence to operate' in a complex, uncertain century. It identifies four common principles—outcome-based, multistakeholder, forward-looking, and multi-dimensional—that link these abilities. To operationalize these, the authors propose a toolkit including Budgeting for Outcomes, Indicator Information Systems, Multistakeholder Councils, Scenario Planning, and Integrated Strategies. The report provides global case studies, such as Germany's sustainability reporting and Washington State's budgeting process, to demonstrate how these tools can be implemented to improve public management and policy resilience.

The policy brief argues that market discount rates are unsuitable for evaluating long-term environmental impacts and proposes the 'equivalency principle' to determine social discount rates. This principle assumes that undeveloped and developed land of identical attributes should provide equal utility to future generations. Using a case study of a proposed seaport in Pasaia, Basque Country, the authors demonstrate that applying this principle results in lower, site-specific discount rates (between 0.96% and 3%) that would lead to the rejection of the project, whereas a market rate of 11% would justify it in some scenarios.

The document argues that the global agro-food system is increasingly inefficient due to a disconnection between crop production and livestock, driven by rising demands for animal protein and high rates of food waste. It highlights that international trade of food and feed has increased eightfold over the last 50 years, leading to significant nitrogen pollution and greenhouse gas emissions. Using Spain as a primary example, the authors demonstrate how a shift from a Mediterranean diet to one rich in animal proteins has increased nitrogen pollution and created 'emission leakage,' where emissions associated with imported feed in non-Annex B countries exceed those from domestic production. The briefing suggests that reducing animal protein intake, decreasing food waste, and reconnecting crops with livestock are essential for global food security and environmental safety.

The Basque Country exhibits a high resource dependency, with a Total Material Requirement of 108 tons per capita in 2004, 83% of which is imported. This consumption pattern drives significant environmental and social degradation abroad, including oil spills in Nigeria, deforestation for palm oil in Indonesia, toxic pollution from nickel mining in Russia, and watershed degradation from tin mining in Bolivia. The document argues that the economic prosperity of developed regions is linked to an unsustainable use of global resources and calls for a transformation in consumption and production patterns to meet basic human needs without exceeding planetary limits.

The research paper examines the cognitive dimensions of urban sustainability transitions (UST) in Bilbao, Spain, using the Q method to identify how stakeholder values and perceptions act as barriers or opportunities for decarbonization. The study identifies four distinct discourses among stakeholders: local followers, confidant visionaries, problem-solvers, and workaday sceptics. While there is a general consensus that energy consumption in the Basque Country is too high and fossil fuels are scarce, significant gaps exist between decision-makers and potential drivers of change. The authors argue that for cities to act as 'transition tractors' rather than mere actors, they must establish knowledge, discussion, and communication (KDC) platforms to link pragmatists, visionaries, and policymakers.

The study analyzes the Spanish domestic appliance market in 2012 to determine the price premium for energy efficiency (EE) labels and the price elasticities of demand. Using a hedonic pricing model, the authors found that high energy efficiency labels lead to price premiums of 4.15% for washing machines, 12.63% for refrigerators, and 4.03% for dishwashers. The analysis also indicates that demand for high-efficiency appliances is more elastic than for low-efficiency ones across all three categories.

The report examines water governance in four European countries, focusing on the implementation of the EU Water Framework Directive (WFD) and the Marine Strategy Framework Directive (MSFD). It finds that while there is a general shift toward integrated, river-basin-based management, significant challenges remain in coordinating freshwater and marine policies, managing spatial boundaries, and ensuring meaningful stakeholder participation. The study highlights diverse models of service delivery, from the privatized system in the UK to the public-private partnerships and user associations in Spain, and the strong tradition of community-led water protection in Finland.
