    Economic input-output analysis was first developed by Wassily Leontief in the 1930s to aid manufacturing planning and has been used ever since in countless applications addressing questions on economy, labour, social issues, trade, energy, ecology, resource use, industrial ecology and environmental science. The compilation of input-output tables of national and regional economies is a routine practice governed by a UN standard. Thousands of analysts and researchers use analytical input-output techniques. Environmental applications of IOA began in the early 1970s when it was widely used for energy analysis. In 1973, Leontief received the Nobel Prize for Economic Science for the development of the input-output methodology and its wide application.
