Environmental Impact Assessment

Environmental Impact Assessment (EIA) is a means of drawing together, in a systematic way, an assessment of the likely significant environmental effects arising from a proposed development.

Developments falling within a description in Schedule 1 to the 2011 EIA Regulations always require EIA. Development of a type listed in Schedule 2 to the 2011 EIA Regulations will require EIA if it is likely to have a significant effect on the environment, by virtue of factors such as its size, nature or location.

  • The requirement for EIA comes from European Directive 2011/92/EU.
  • In Scotland, the EIA Directive has been brought into Scottish law through a number of Scottish Statutory Instruments relevant to individual consenting regimes. These pages relate to the Town and Country Planning EIA regime - information on other Scottish EIA regimes is available.
