GRI environmental performance indicators

The indicators relating to the environmental performances (core and additional) envisaged by the GRI-G3.1 Guidelines, edition 2011, together with the indicators introduced by the Sector Supplement for Utility companies in the electric sector are shown below106, with indication of the sections and pages of the report where it is possible to find them. The meaning of each performance indicator is illustrated in the Guidelines and Sector Supplement, available on the website www.globalreporting.org.

The quantitative environmental figures are illustrated in the Environmental accounts, an integral part of the Sustainability Report, made up of around 250 items which describe the production values, the factors used (the resources), and the external outputs (waste and emissions). The Environmental accounts also include the presentation of around 60 indicators/parameters of environmental importance, selected so as to clearly and concisely describe the Group’s performances.

    Environmental issues pages 183, 184 (limited to the cooling process of the thermoelectric plants)

106The indicators of the Sector Supplement for Utility companies in the electric sector (EU) are supplemented in the table; the text disciplines distinct matters for energy companies, introduces new indicators (EU) and a number of in-depth notes (commentary) relating to indicators already envisaged by the 2006.

Biodiversity

EN11 (Core)

  • Location and size of land owned, leased, managed in, or adjacent to, protected areas and areas of high biodiversity value outside protected areas.
    Environmental issues pages 159, 175

EN12 (Core)

  • Description of significant impacts of activities, products, and services on biodiversity in protected areas and areas of high biodiversity value outside protected areas.
    Environmental issues page 159

EU13

  • Biodiversity of offset habitats compared to the biodiversity of the affected areas.
    Environmental issues page 159

EN13 (Additional)

  • Habitats protected or restored.
    Environmental issues page 159

EN14 (Additional)

  • Strategies, current actions, and future plans for managing impacts on biodiversity.
    Environmental issues page 159

EN15 (Additional)

  • Number of IUCN Red List species and national conservation list species with habitats in areas affected by operations, by level of extinction risk (*).
    At present, this item is not monitored, but the Group carries out its activities strictly respecting and protecting the natural habitats concerned and the fauna and flora present in the areas it operates in.

 

Emissions, Effluents and Waste

EN16 (Core)

  • Total direct and  indirect greenhouse gas  emissions by weight.
    Environmental issues pages 185, 186; Environmental accounts pages XIV, XVI, XVII 

EN17 (Core)

  • Other  relevant indirect greenhouse gas  emissions by weight.
    No significant emissions to report

EN18 (Additional)

  • Initiatives to reduce greenhouse gas  emissions and  reductions achieved.
    Environmental issues page 172

EN19 (Core)

  • Emissions of ozone-depleting substances by weight.
    Environmental issues page 186

EN20 (Core)

  • NOx, SOx, and  other significant air emissions by type  and  weight.
    Environmental issues page 186; Environmental accounts pages XIV, XVI, XVII

EN21 (Core)

  • Total water discharge by quality  and  destination.
    The water which  is used by the  Acea  Structures for “civil/sanitary” use  (around 1 Mm3   in 2011) underwent the  same standard purification treatment which  all the  civil waste water is subject to. The environmental impact on the  receiving water body  by the  discharge of the  treated water is particularly contained.

EN22 (Core)

  • Total weight of waste by type  and  disposal method.
    Environmental issues pages 186, 187; greater details in the  Environmental accounts

EN23 (Core)

  • Total number and  volume of significant spills.
    In 2011,  as already occurred over  the  last  few years, there were no significant spills into the  environment of polluting substances such as mineral oil, fuel or chemical products.

EN24 (Additional)

  • Weight  of transported, imported, exported, or treated waste deemed hazardous under the  terms of the  Basel
    Convention Annex  I, II, III, and VIII, and  percentage of transported waste shipped internationally.
    Waste classified as ”hazardous”, monitored as indicated by EN22, is transferred to specialized and  authorized external companies. At present, the  item  is not  additionally monitored.
    Environmental issues pages 186, 187

EN25 (Additional)

  • Identity, size, protected status, and  biodiversity value  of water bodies and  related habitats significantly affected by the  reporting organization’s discharges of water and  runoff.
    No discharge to be reported which  significantly affected the  habitats or biodiversity.

 

(*) The IUCN (International Union for the Conservation of Nature) list, to which the EN15 indicator refers, concerns endangered species (www.iucn.org).

Products and services

EN26 (Core)

  • Initiatives to mitigate environmental impacts of products and  services, and  extent of impact mitigation.
    The products supplied (electricity, heat, drinking  water, treated water and  public  lighting) do not  have  significant environmental impacts since they  do not  give rise  to either pollution or harmful emissions. The initiatives focus  on the reduction of the emissions into the  atmosphere (due  to thermoelectric generation).
