Dashboard 4: Environmental sustainability?, contains a selection of 10 indicators that cover environmental sustainability and environmental threats. On environmental sustainability there are seven level and change indicators related to: energy consumption, carbon dioxide emissions, change in forest area and fresh water withdrawals. Three environmental threats indicators are mortality rate attributed to household and ambient air pollution and to unsafe water, sanitation and hygiene service and the International Union for Conservation of Nature and Natural resources’ Red List Index that measures aggregate extinction risk across groups of species. Based on the performance on each indicator, countries are divided into three groups of approximately equal sizes (terciles) – the top third, the middle third and the bottom third. Three-colour coding visualizes a partial grouping of countries by indicator. It can be seen as a simple visualization tool as it helps the users to immediately picture the country’s performance. Cut-off values that are defined by terciles of distribution of each indicator are given in Technical note 6.
