Deadweight
The Green Book, Central Government Guidance On Appraisal And Evaluation, Published by HM Treasury in 2020, suggests that deadweight refers to: '...allowing for outcomes that would have taken place without the intervention under consideration. Deadweight will be revealed when the total outcome of an option for intervention is compared with business as usual, the (BAU).'
The 2018 Green Book, suggested that deadweight refers to: ‘…outcomes that would have occurred without the intervention. This is used to determine the difference that can be attributed to an intervention.’
Deadweight can also refer to the weight of an inert object, or to the load capacity of a ship.
