Calls have been made for the Scottish Government to "take action" after it was revealed that only 14% of its fleet of cars are green vehicles.
Out of the 208 cars the Government has, 26 are hybrid vehicles and three are electric.
The figures were released in answer to a Parliamentary Question by Liberal Democrat transport spokesman Jim Hume.
He said: "The SNP love to say that they are world leaders on climate change, making the most of every opportunity to talk the talk on the environment. However these answers reveal that the SNP are not taking enough action in Government to back up their warm words.
"With only 14% of their fleet either hybrid or electric, they are not setting the example that we would hope for from a government that has set significant climate change targets.
"The technology for electric or hybrid cars is improving and the cost of electric vehicles has dropped significantly so it would be good to see this SNP Government making more use of them.
"By opting for vehicles with cleaner emissions they could be setting a real example for the rest of the country to follow.
A Scottish Government spokesman said: "Our priority is to ensure the Government car service is delivered in the most efficient and cost-effective manner, offering the best deal for the taxpayer.
"Our fleet includes hybrid and electric vehicles and the typical vehicle now purchased for use by Ministers has CO2 emissions that are 31% lower than the vehicles used by ministers before 2007.
"Electric vehicles are suitable for short urban use, rather than for travel across Scotland as ministers and officials do on Government business."
