Dashboard 4: Environmental sustainability, contains a selection of 12 indicators that cover environmental sustainability and environmental threats. The eight indicators on environmental sustainability are fossil fuel energy consumption, renewable energy consumption, carbon dioxide emissions (expressed two ways), forest area (expressed two ways), fresh water withdrawals and natural resource depletion as a percentage of gross national income. The four indicators on environmental threats are mortality rates attributed to household and ambient air pollution and to unsafe water, sanitation and hygiene services; degraded land; and the International Union for Conservation of Nature’s Red List Index, which 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.
