Emissions Inventory

The Emissions Inventory (EI) dataset collects data from regulated industrial activities and includes annual emissions to air and controlled waters, off-site transfers of waste and transfers of pollutants to wastewater. The NRW EI includes all the data from Wales that is published on the UK Pollutant Release and Transfer Register (UK PRTR) but also includes further emissions that are under the UK PRTR threshold. The EI includes reporting on annual emissions of certain substances to air, controlled waters and land, and off-site transfers in wastewater and waste. You must report to the EI if you: operate under a Part A (1) Environmental Permit and have received a notice under Regulation 60 of the Environmental Permitting Regulations 2010 operate a sewage treatment works with a capacity at, or over, 100,000 population equivalents (PE) dispose of radioactive waste to air, water or sewers covered by a permit issued under the Environmental Permitting Regulations 2010 run an opencast mine or quarry with a surface area over 25 hectares, or an underground mine and related operation (no capacity threshold).
