The Panorama programme, now scheduled for airing in late July, interviewed about six Timber Trade Federation (TTF) members as part of its investigation, which is believed to have a strong focus on the trade of African tropical timber to the UK.
The TTF has been involved with the programme makers for six months, meeting researchers several times, including visits to the corporation’s studios.
"We have tried to be as open and honest as we can," said David Hopkins, TTF head of communications and external affairs.
"It’s our view that we should be as transparent about the whole industry. The truth is the industry is in good shape and there is very little in the UK which is primary trade of illegally-logged goods and that is in no small part due to the introduction of our Responsible Purchasing Policy.
"There’s been an increase in certified products and a decrease in higher risk material, which we are pleased with, and that is a very good news story for the industry. So we feel confident we do not have an enormous case to answer.
"However, that does not mean there will not be question marks raised in the programme or slurs."
Mr Hopkins said TTF members interviewed had not been confronted with any trump cards accusing them of being guilty of trading in illegal wood.
"The programme may highlight bad practices and I’m worried it may give a bad name to tropical timber generally, which is not a good outcome. It might taint the name of tropical timber as a whole," said Mr Hopkins.
