Speaking at the Association of County Councils annual conference in Leicester today, Mr Dobson said the document would be ready in time for the party's local government conference.
Once the local government conference had considered the paper, it would form the basis of a policy document to be presented to the party's annual conference next autumn, he said.
Mr Dobson was reluctant to comment on current local government reforms but he said Labour remained committed to unitary councils and regional government in England, a Welsh assembly and a Scottish parliament.
It was not possible to comment in detail on the contents of the green paper but it was likely to urge scrapping such practices as compulsory competitive tendering, said Mr Dobson.
Mr Dobson said he personally preferred regional government which reflected existing natural geographic boundaries rather than the imposition of regions of uniform size and population.
