EU Environmental Impact Assessment Directive
European Union directive requiring environmental impact assessment of major public and private projects before development consent is granted.
Definition
The EIA Directive, originally adopted in 1985 and codified as Directive 2011/92/EU with later amendments, requires member states to ensure that projects likely to have significant environmental effects — from motorways to intensive farms — are assessed before consent. The assessment must cover direct and indirect effects on population, health, biodiversity, land, water, air and climate, with public participation.

Why it matters
It is the EU workhorse of preventive environmental law and the regional anchor of the global EIA discipline NEPA began.
