Although this metric has been presented as a potential game-changer within the ad industry, it has not been fully adopted by the stakeholders, mainly due to disagreement between the different parties on the standards to implement and measure it, and its potential benefits and drawbacks. In this study, we present a survey of the role that viewability can have on the main challenges of the online advertising ecosystem depicting the main applications, benefits and issues. With this objective, we provide an overall picture of how viewability can fit within the ecosystem, which can help the different stakeholders to work on its adoption, integration and establishing a research agenda. ; This work was supported by the Plan de Doctorados Industriales de la Secretaría de Universidades e Investigación del Departamento de Empresa y Conocimiento de la Generalitat de Catalunya under the Grant 2018-DI-059 and by ExoClick.

Abstract
The pressure global food systems exert on the environment has amplified over time, following the growth of the human population, changes in the food consumption patterns and intensification of the production systems. Without changes in food systems, an overpressure on agriculture and food production will be unavoidable, with inevitable consequences for the environment and human health. Animal‐derived protein production like meat and milk is among the most important drivers of this impact. Under this context, the evaluation of the health and sustainability impacts of alternatives for animal‐based food proteins are central aspects of this discussion. Health risk‐benefit assessment (RBA) of foods estimates the overall human health impact following exposure to a particular food or food component, integrating risks and benefits in comparable measures. Methods that simultaneously consider the environmental impact of the food production systems were needed to perform a sustainable holistic assessment. "ALTERNATIVA | Alternative protein sources in the European diets – integrating health risk‐benefit and sustainability" aimed to develop a holistic approach to assess the impact of alternative protein sources, integrating health and sustainability assessment. This project, considering five complementary work packages, developed activities to enhance the capacity‐building among members of the consortium in applying methodologies related to the health RBA and sustainability impact assessment; to develop, in collaboration with different stakeholders, a protocol to integrate the assessment of the impact of foods/diets on health and on sustainability; to apply the derived framework to a case study, to validate it with a real case scenario, estimating the health and sustainability impacts of replacing red meat consumption by pulses in two different countries; and to disseminate and promote the established method of integrated health and sustainability assessment to other potential EU users. This external scientific report summarizes the main outputs and results obtained in the context of the ALTERNATIVA project.
