Introduction. The EmBI is obtained from the
relationship of conventional economic value
(CEV) between the emergy economic value
(EEV). For EEV the emergy approach was used
to convert the amounts exported (kg) to emergy
values. Emergy, unlike the conventional costbenefit analysis, is a measure of the value of
human work plus the work done by nature in
the generation of a good or resource. Objective.
The aim of this study was to propose an indicator
(Emergy Benefit Index - EmBI) to measure the
sustainability of exports of the agricultural
sector of a country. Materials and methods. To
check the validity of the proposed method data
of the exports in the agricultural sector of Peru
between 1994 and 2014 was taken. Results and
conclusions. A reading of this proposed indicator
can show that Peruvian agricultural exports was
unsustainable only in 2001 and 2002; other years
this economic sector is manifested as sustainable,
although from 2005 sustainability increases,
reaching the year 2014 a EmBI of 1.64. This
indicator would measure if an economy receives
fair price due to exports (EmBI more than 1) or
not (EmBI under 1).
