Commenting on the appointment Mr Stevenson said:
"I am delighted to be a member of the new Scottish Ministerial team in the first SNP government in history. This has been a tremendous week for the people of Scotland and one which I hope will herald a new era in Scottish politics, an era of co-operation and effective decision-making.
"A key part of serving in Government is ensuring you hear at first hand the concerns of individuals and businesses. I have always listened carefully to my constituents and in Government it will be my priority to continue to serve all of my constituents.
“Transport, infrastructure and climate change are issues of vital importance to Scotland’s economy and indeed the quality of life of people in Scotland. In my role as Minister I look forward to advancing an improved, safer and greener transport network here in Banff & Buchan and across Scotland.”
