• Map data
Description: Land area (sq. km)
Source: World Bank
Description: Population, total, 2013
Source: World Bank
Description: Total GDP (PPP, current international $)
Source: World Bank
Notes: Most data for 2013, but with some infilling of blanks from earlier years.
Description: Potential CO₂ emissions from annual extracted fossil fuels, 2013
Source: BP Statistical Review of World Energy 2014, converted to CO₂ by Duncan Clark, using the following BP conversion factors: oil, 3.07 tonnes CO₂ per tonne; gas, 2.35 tonnes CO₂ per tonne of oil equivalent; coal, 3.96 tonnes per tonne of oil equivalent.
Description: Total emissions of CO₂ from fossil fuel burning and cement production, 2013
Source: Glen Peters et al., Global Carbon Project
Description: Carbon footprint of all goods and services consumed, 2012
Source: Glen Peters et al., Global Carbon Project
Description: Cumulative CO₂ emissions from energy use, 1850–2011
Source: WRI, Climate Analysis Indicators Tool.
Description: Potential CO₂ emissions from "proven" fossil fuel reserves, end of 2013
Source: BP Statistical Review of World Energy 2014, converted to CO₂ by Duncan Clark, using the following BP conversion factors: oil, 3.07 tonnes CO₂ per tonne; gas, 2.35 tonnes CO₂ per tonne of oil equivalent; coal, 3.96 tonnes per tonne of oil equivalent.
Description: People exposed to droughts, floods and extreme temperatures
Source: World Bank
Notes: Original dataset was % of population exposed in the period 1990–2009. This has been multiplied by the 2013 population to give an estimate of the people currently exposed.
Description: Population living less than 5m above sea level
Source: World Bank
Notes: Original dataset was % of population. This has been multiplied by the 2013 population to give an estimate of the total population currently living below 5m.
Description: Population living below $1.25 a day
Source: World Bank
Notes: Calculated by multiplying the 2013 population total by the % of population living on less than $1.25 in the most recent year for which data is available.
Description: Change in CO₂ emissions, 1990–2008
Source: Glen Peters et al., Global Carbon Project
Description: CO₂ emissions per capita, 2013
Sources: see Carbon Emissions and Population above.
Description: GDP per capita, 2013
Source: World Bank
Notes: Data from 2013 with some gap-filling from earlier years.
Description: Rate of annual population growth, 2013
