Statutory guidance: Transitional National Plan (TNP): quarterly register

Updated: Updated TNP register 2018: quarter 2.

The TNP is issued by Defra in accordance with Article 32 of the Industrial Emissions Directive (IED) and associated guidance.

The IED sets minimum limits for emissions of sulphur dioxide, nitrogen oxides and dust to the air from large combustion plants with a thermal rating equal to or greater than 50 megawatts.

The TNP scheme allows large combustion plants first licensed before 27 November 2002 to trade their annual allowances for sulphur dioxide, nitrogen oxide and particulate matter (dust) with other large combustion plants within the TNP scheme.

The TNP register is maintained by the Environment Agency on behalf of the 4 UK regulators:

  • Environment Agency
  • Natural Resources Wales
  • Northern Ireland Environment Agency
  • Scottish Environment Protection Agency
