National Environmental Accounting Database

The National Environmental Accounting Database (NEAD), compiles detailed information for over 150 countries for the full array of resources that underlie economies, including environmental flows (sunlight, rainfall), natural capital stocks (soil, water, forests, fish), mined materials (metals, fuels) and economically transformed goods and services (agricultural commodities, manufactured goods, services). Data for commodities and trade flows are for the years 2000, 2004 and 2008, and long-term average data are used for climate and hydrology flows.

The first version of NEAD was produced in 2006 and contains complete syntheses for 134 countries for the year 2000. With the support of the International Society for the Advancement of Emergy Research (ISAER), a second version of NEAD was produced in 2012, with additional years 2004 and 2008, and more countries. Also, UEVs were updated according to new research which have altered the results for the year 2000.
