The campaign is aimed at parents and children

Environment Minister Ross Finnie said the Scottish Executive campaign would encourage people to take steps "to live within their environmental means".

The "It's our future" campaign is aimed at parents and children.

The Scottish Greens said the Scottish Executive publicity campaign would be better directed at ministers.

Mr Finnie said: "We need to encourage everyone in Scotland to adopt a more sustainable way of life and protect the world we live in.

'Hugely impressed'

"Children are at the forefront of this campaign for a good reason - they will live with the consequences of our actions."

The environment minister said he had been "hugely impressed by the enthusiasm and commitment" of children in Scotland.

"It is important that each person looks at their behaviour when at work, at home and at leisure to see where we can reduce our impact on the planet," he said.

"We all need to recognise that it's our future, and start to translate our intentions into action."

By continuing to build motorways and expand aviation for example, it is clear that current executive ministers say one thing and do another Mark Ruskell Scottish Greens

The Scottish Greens said "political leadership" was needed more than anything else to help people to change.

Green MSP Mark Ruskell said ministers were "utterly failing" to take issues such as climate change seriously.

He said: "It is Mr Finnie's fellow Lib Dem minister Nicol Stephen, who, according to Friends of the Earth made the 'worst environmental decision' since devolution by approving the M74 motorway project.

"By continuing to build motorways and expand aviation for example, it is clear that current executive ministers say one thing and do another."
