I spoke to Adam Wilkins of CKC at Stoneleigh to confirm that the Kit car emissions proposals had been abandoned...he said that as well as the phone call they had received an email from the DfT.
I'm keeping an eye on the DfT website but as Peterux has said in the BIVA Builds thread on this forum there has been no update of the official website.

It appears that they are still analysing the feedback!
