BOTH Labour and the Liberal Democrats have rounded on the Scottish Government's record on climate change, saying it is all talk and no substance.

Labour's Shadow Environment Secretary, Claire Baker said there had to be a "serious, credible and urgent plan" to meet targets, while her Liberal Democrat counterpart, Jim Hume, said only 14% of the Government's vehicle fleet, 29 out of 208, are hybrid or electric models.

Ms Baker said: "The SNP is relying on a 10-fold increase in cycle journeys to reach its climate change targets, but is slashing the budget to promote cycling. Only last month, Audit Scotland warned that is a mistake.

"We have set really tough climate change laws in Scotland, but we need a credible plan to meet the targets. Transport and housing are predicted to be the biggest polluters in coming years so we have to make changes."

She added: "We need a serious, credible, and urgent plan to implement our climate change laws in a way that is fair and economically sustainable."

Mr Hume said: "With only 14% of the fleet either hybrid or electric, [the SNP] is not setting the example we would hope for from a Government that has set significant climate change targets.

"By opting for vehicles with cleaner emissions they could be setting a real example for the rest of the country to follow."

A spokesman for Minister for Transport Keith Brown said: "Since 2007, the Scottish Government has invested £83 million in infrastructure and softer measures to encourage more active travel, including expansion of the National Cycle Network and local links to enable more people to travel by more active means for their everyday journeys.

"We have only recently announced a £2.2m funding package to help boost healthier, greener and more affordable travel across the country, including £1.3m to help increase Scottish cycling rates. And we are developing the Future Transport Fund which will enable us to support better public transport, including active travel initiatives.

"We are also committed to tackling climate change. The Climate Change (Scotland) Act 2009 introduced world-leading legislation to reduce emissions by at least 80% by 2050."
