TVAs Environmental Impact Index
As part of its Environmental Management System, TVA has established a set of indicators to assess and manage the beneficial and detrimental effects of its activities on air, water, land, energy use, and waste production. These indicators enable TVA to measure its progress and set targets for future improvement.
A subset of these indicators is used to compile the Environmental Impact Index (EII), which gives a snapshot of TVA’s overall environmental performance as measured against a baseline of fiscal year 2002.
As conditions change, TVA may revise its target data for the EII indicators.
