The financial commitment to environmental protection made in 2013 by the Enel Group's overall industrial perimeter is shown in the following table:
|Production chain (Milion of euro)||Investment||Current expenses||Total|
|Thermal electricity generation||125||204||329|
|Other activities (including mining and environmental support)*||95||65||160|
* “Environmental support” are consulting and guidance activities non directly pertaining to a specific chain.
Environmental expenses (investment and current expenses) are recognised according to a classification system based on the criteria adopted by Eurostat and Istat (the Italian Statistical Institute). Under Istat's criteria, “environmental protection expenses” are defined as the costs incurred for preventing and mitigating environmental pollution and degradation and for restoring the quality of the environment, regardless of the origin of such costs (legislation, agreements with local governments, corporate decisions, etc.). It excludes expenses incurred for minimising the use of natural resources, as well as for activities that, albeit environmentally beneficial, primarily satisfy other requirements, such as health & safety at workplaces. The term “expenses” has always an algebraic sense, as it may also refer to revenues, such as those which may accrue from waste delivery to recovery operators.
