"The Chief Secretary has been asked to examine the proposals by consultations with the departments concerned and put only viable schemes in the meet's official website," Chief Minister Oommen Chandy told reporters at a cabinet briefing.
The government's decision comes in the wake of reservations by CPI(M) led LDF Opposition and some Congress leaders, locally known as 'Green' MLAs, over certain schemes.
Referring to criticism that government lacked transparency and environmental concerns had not been addressed while drafting investment schemes, Chandy said it was a "deliberate campaign" against the meet and it was most unfortunate.
"All projects that came was put on the official website.
But the propaganda is that all schemes appearing in it have been approved by the government. In view of this misinterpretation of facts, the government has decided to have a screening of the proposals," he said.
Henceforth, only those projects that are practicable would come for the discussion at the three-day meet, to be inaugurated by Prime Minister Manmohan Singh at Kochi on September 12, he added.
The Chief Minister said the cabinet also decided to constitute an Investment Clearance Board for speedy screening and examination of the projects cleared at the meet.
Denying the charge that the meet would end in the sale of state's resources, mainly land, to private parties, Chandy said the government would not sell an inch of land.
The proposals were to lease out land for projects that would protect the interest of the state and benefit people, he said.
