A report has revealed that public sector staff in Scotland are too dependent on air travel rather than rail services, and have flown to London up to 100 times as frequently as taking the train in the last year.
The report by Transform Scotland showed that the most regular fliers included the police and universities, and fewer than one in five of the 78 public bodies which responded to the survey used rail more than air.
However, good practise was found to be carried out by West Lothian Council, as well as the Scottish Environment Protection Agency (SEPA) who cut its mainland UK flights by 96%.
It also commended the National Library of Scotland for their efforts on travel planning, and called on others to "show such leadership".
But the campaign group said much more needed to be done to help deliver Scotland's climate change targets. Transform Scotland chairman Phil Matthews said, "Transport is one of the key sources of greenhouse gases and public bodies have a vital role to play in cutting emissions.
"It is therefore surprising that the wider public sector appears to be taking so little action to help deliver Scotland's legally binding climate change targets.
"We find it particularly dismal that over 60% of public bodies do not have a travel plan in place, despite this being the most effective way to cut emissions from the transport sector, and after a decade or more of free travel planning advice being offered to them."
He said public bodies should be given a year to improve their record, and those failing to take action should be held to account by the Scottish ministers.
