The National Environmental Accounting Database (NEAD), compiles detailed information for 169 countries about 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 production, extraction, and trade flows are from 2000, 2004 and 2008, while long-term average data are used for climate and hydrology flows.
