A theme paper for the Strategic Environmental Assessment (SEA) examining 'Air and Climatic Factors' and 'Resources and Waste' topics.
The Air and Climatic Factors topic covers two main areas, Air Quality and Carbon Footprinting. The Air Quality topic focuses emissions of sulphur dioxide (SO2), particulate matter (PM10) (fine particles) and nitrogen oxides (NOx). The assessment covers potential effects of Severn Tidal Power Options on local air quality and human health (ie South West and Wales), in addition to national contributions to air quality. The Carbon Footprinting topic focuses on greenhouse gas emissions (GHG), principally carbon dioxide (CO2). The assessment considers potential changes in GHG emissions, in the UK and globally, as a result of a Severn Tidal Power option being implemented.
The Resources and Waste topic includes sources of construction materials, energy, water and waste management facilities. The key environmental issues for resources relate to the types and quantities of resources required, the source of those resources, and the effects on the landscape from the use of natural resources and their transportation. Key issues for waste relate to the types and quantities of waste generated, how they would be managed, and where they would be disposed, treated, reused or recycled.
