Labour MSP Cathy Jamieson said the Scottish government's Freight facilities grants (FFG) had contributed to reducing carbon emissions and congestion by moving freight to rail and sea, on 13 January 2011.
Ms Jamieson said awards totalling £68.9 million had been made to projects in Scotland and this had reduced the need for 33,573,500 lorry miles per year.
However she regretted the Scottish government's proposals to reduce support for the freight industry from £10.3 million in 2010-11 to £2.9 million in 2011-12, and was concerned that this would put in jeopardy the work that has been done across Scotland.
Transport Minister Keith Brown confirmed that £2.9million had been allocated to support the freight industry in 2011-12.
However he said they could not fund new FFG projects for the time being and said that the FFG scheme was a discretionary grant scheme and applicants could never be certain of grant support during the project development stage.
Mr Brown ended by saying the situation was not as bleak as it seemed at the beginning of the debate and "if others take different decisions to help us with the resource situation that we are in, the matter can be looked at again".
