The British Soft Drinks Association (BSDA) is in talks with key players such as Coca-Cola and Britvic, in advance of releasing recommendations to members.
They are believed to be along the lines of the Guideline Daily Allowance scheme favoured by the Biscuit Cake Chocolate and Confection-ery Association.
A spokesman for the BSDA confirmed it is looking at making labelling recommendations to members.
He said: 'The soft-drinks industry is getting more diverse and any scheme has to be able to cope with this. For example, a fruit-juice drink may be one of the government's recommendations for five portions of fruit a day, but has a high proportion of sugar.'
Industry insiders have said the Food Standards Agency's traffic-light food-labelling scheme would not be appropriate for drinks.
