I'm not aware of consultations with industry; you'd have to check with Environment on that. A key element of models is what's called the elasticity of substitution, or the extent and the ease to which firms can substitute technologies in the face of a change in price, which is essentially what we're doing here.
So the models would implicitly have a historical estimate of those types of changes. But to my knowledge, there was no survey of firms done to estimate what would be required per firm, for example.
