Plans to reduce workforce car numbers entering Sellafield 11/03/2021 Sellafield has committed itself to âambitiousâ targets on promoting sustainable travel, including a focus on encouraging a reduction in car use by its workforce. The latest version of Sellafieldâs Travel Plan outlines a number of goals the firm is aiming for in the coming years, including a target to reduce the number of vehicles entering the site each day from more than 6,000 to as low as 4,000. The plan has been shared with Cumbria County Council, and its local committee for Copeland, made up of county councillors representing the area, considered the proposals at its meeting last week.
