Abstract	Air travel has a decisive role in the spread of infectious diseases at global level. We present a methodology applied during the early stages of the COVID-19 pandemic that uses detailed aviation data at final destination level in order to measure the risk of the disease spreading outside China. The approach proved to be successful in terms of identifying countries with a high risk of infected travellers and as a tool to monitor the evolution of the pandemic in different countries. The high number of undetected or asymptomatic cases of COVID-19, however, limits the capacity of the approach to model the full dynamics. As a result, the risk for countries with a low number of passengers from the Hubei province appeared as low. Globalisation and international aviation connectivity allow travel times that are much lower than the incubation period of infectious diseases, a fact that raises the question of how to react in a potential new pandemic.

Abstract	In France, around 70% of conventional industrial foods are ultra-processed, with no data for organic foods. The objectives of this study were to evaluate the percentage of ultra-processed foods (UPFs) in industrially packaged organic (n = 8554) and conventional (n = 45,791) foods, and to describe their marker of ultra-processing (MUP) profiles. The percentage of UPFs and MUP profiles were determined with the Siga methodology. UPF percentages were 53% in organic foods and 74% in conventional foods, and there was 8% more organic UPFs in conventional stores than in organic stores. The more additive MUPs are used, the greater the quantity of nonadditive MUPs. Conventional UPFs contained twice as many total MUPs as organic UPFs. Main MUPs in organic UPFs were refined oils, extracts and natural aromas, native starches, glucose syrup, lecithins and citric acid. Organic foods are, therefore, overall less ultra-processed although still containing high levels of nonadditive MUPs.

Abstract	Worldwide, foods are scored with composition indices. However, processing scores are now emerging. The objective of this study was to study the interconnectedness of the degree of processing and composition for 28,747 industrially packaged foods (71.6% of ultra-processed foods, UPFs) representative of retail assortments. The Nutri-score and Traffic Light Labelling System (TLLS) were used to assess the composition, and the Siga index was used to assess the degree of processing. On average, the more nutritionally favourable Nutri-score and TLLS groups exhibited 56.5 and 50.0% UPFs, respectively. Among markers of ultra-processing non-additives mostly included added fat/sugar/fibre/vitamin, animal and/or plant protein isolates, and taste exhausters, while additives mostly included sweeteners and taste exhausters, suggesting that markers of ultra-processing (MUP) are added to foods to improve composition scores. In conclusion, both types of scores are not complementary as such but obey to a fundamental hierarchy: processing first, then composition if necessary.

Abstract	The qualitative NOVA classification of foods according to their degree of processing is used worldwide by researchers. NOVA defines ultra-processed foods (UPFs) by the presence of processed industrial ingredients and additives to modify the sensory properties (aroma, taste, colour and texture) of reconstituted food, named 'cosmetic' compounds, i.e., modifying food appearance. Some drastic processes directly applied to food are also markers of ultra-processing. However, with the intent to develop an elaborate tool for industries and retailers, the Siga classification was developed by combining the four holistic NOVA groups with four more new reductionist subgroups considering the impact of processing on the food/ingredient matrix; the contents of added salt, sugar and fat; the nature and number of markers of ultra-processing (MUPs); and the levels of at-risk additives (groups are unprocessed, A0; minimally processed foods, A1; culinary ingredients, A2; balanced foods, B1/C0.1; high salt, sugar and/or fat level foods, B2/C0.2; processed/ultra-processed foods; and UPFs with more than one MUP, C1). The Siga algorithm was used to characterize 24 932 packaged foods in French supermarkets (baby foods and alcohol excluded), which were representative of the packaged food assortments. The main results showed that two-thirds of the products were ultra-processed. Products with more than one MUP (C1) corresponded to the most represented category, accounting for 54% of the products. Among foods with more than five ingredients, 75% were UPFs. Considering all products, the average number of ingredients, MUPs and at-risk additives were 10.1, 2.6 and 0.5, respectively. Among food categories, some contained a high percentage of UPFs: 94, 95, 95, 81, 80, and 87% for salted meats, cooked dishes, flavoured yogurts/white cheeses, energy and gourmet bars, breakfast cereals, and vegetarian dishes, respectively. Finally, the Siga algorithm presents a useful tool for improving the health potential of packaged food and for decision-making on search engine optimization (SEO) policy and assortment management in supermarkets.

Abstract	Urban accessibility and congestion indicators allow us to benchmark cities. If these indicators are also available at a fine resolution, we can compare different neighbourhoods within a city. We present a dataset of different accessibility indicators for all urban areas with more than 250 thousand people in the EU27, the UK, Switzerland and Norway. Each city is analysed by means of a population grid of 500 m by 500 m and represented by a wider area covering both the densely populated urban centre and the commuting zone. To capture congestion, we measure accessibility for each grid cell at different times of the day that correspond to different traffic conditions using the detailed network and congestion information provided by TomTom.

Article: Review of sustainability indices and indicators: Towards a new City Sustainability Index (CSI)

Abstract	The purpose of this paper is to discuss conceptual requirements for a City Sustainability Index (CSI) and to review existing major sustainability indices/indicators in terms of the requirements. The following indices are reviewed: Ecological Footprint (EF), Environmental Sustainability Index (ESI), Dashboard of Sustainability (DS), Welfare Index, Genuine Progress Indicator (GPI), Index of Sustainable Economic Welfare, City Development Index, emergy/exergy, Human Development Index (HDI), Environmental Vulnerability Index (EVI), Environmental Policy Index (EPI), Living Planet Index (LPI), Environmentally-adjusted Domestic Product (EDP), Genuine Saving (GS), and some applications of composite indices or/and multivariate indicators to local or regional context as case studies. The key conceptual requirements for an adequate CSI are: (i) to consider environmental, economic and social aspects (the triple bottom line of sustainability) from the viewpoint of strong sustainability; (ii) to capture external impacts (leakage effects) of city on other areas beyond the city boundaries particularly in terms of environmental aspects; (iii) to create indices/indicators originally for the purpose of assessing city sustainability; and (iv) to be able to assess world cities in both developed and developing countries using common axes of evaluation. Based on the review, we conclude that it is necessary to create a new CSI that enables us to assess and compare cities' sustainability performance in order to understand the global impact of cities on the environment and human life as compared with their economic contribution. In the future, the CSI will be able to provide local authorities with guidance toward sustainable paths.
