What鈥檚 a Fair Share of Energy?
Equitable resource distribution requires the world鈥檚 affluent countries to reduce their ecological impact while low-income nations gain greater access to resources until there is convergence. And where should that convergence happen? For energy distribution, researchers at the International Institute for Applied Systems Analysis say the minimum global energy flow required to achieve universal decent living standards could be as low as 500 watts per capita. Less draconian, the International Energy Agency projects that the U.N.鈥檚 Sustainable Development Goals can be achieved worldwide with an energy flow of about 1,300 watts per capita鈥攁bout what Cuba uses.
Data source: World Bank, latest International Energy Agency data available for each country.

What鈥檚 a Fair Share of Housing?
A solidly built home with adequate floor space, electric lighting, thermal comfort, and good indoor toilets. How much? For a household of up to three people, a minimum of 323 square feet plus 107 additional square feet per occupant beyond three.

What鈥檚 a Fair Share of Food?
An adequate daily consumption of protein, vitamins, and minerals. How much? For optimal health, 2,353 calories daily for an average adult.

What鈥檚 a Fair Share of Water?
A safe, reliable water supply. How much? Minimum of 13 gallons daily per capita.
