Green MSP Patrick Harvie saw his amendment, which called for the Scottish government to reject plans to build a new coal-fired power station at Hunterston, carried at decision time.
During the climate change debate, Mr Harvie told MSPs the proposed power station would be incompatible with the emissions targets and that large-scale carbon capture and storage had never been successfully demonstrated.
Labour's environment spokeswoman Sarah Boyack, who led the debate on 18 March 2010, said more action and less talk was needed to address the "lack of delivery on climate change" in Scotland.
Ms Boyack called for action from the Scottish government to reach emissions targets set out in the 2009 Climate Change (Scotland) Act.
Scotland's plan to make a 42% cut in emissions by 2020 is seen as among the most ambitious in the world.
Ms Boyack suggested the government should replace their ministerial limousines with a clean, green fleet of battery powered electric vehicles.
She said that the Scottish government needs to set an example, to enable the roll-out of electric vehicles.
Climate Change Minister Stewart Stevenson said he could not comment on the plans as they are under consideration by the government, but he did call for the European Union and UK government to take action to support Scotland's ambitious plans and targets.
