The Scottish Government has published its new strategy to tackle climate change amid criticism from campaigners that it does not go far enough.

Climate change secretary Roseanna Cunningham acknowledged that the Government's final climate change plan would be "challenging" to achieve but insisted it was "ambitious and realistic".

The plan sets out how the Government intends to achieve a target of reducing emissions by 66% by 2032.

It includes the commitment for 50% of all of Scotland's energy needs to be delivered by renewables by 2030.

By 2032 transport emissions are to be cut by 37%, new petrol and diesel cars phased out and low emission zones will be introduced in cities across the country.

Other targets for that year include a 33% reduction in emissions from buildings and woodland to be increased from 18% to cover 21% of Scotland.

The plan also stipulates that 70% of all waste will be recycled by 2025. Environmental campaigners said the plan had failed to tackle agricultural emissions and had taken a step backwards in some areas.

Tom Ballantine, chair of Stop Climate Chaos Scotland, said: "In areas such as reducing emissions from our homes the government has significantly decreased ambition from its first draft.

"Particularly short-sighted is the failure to put in place any credible plan to help farmers to reduce their climate impacts, despite the fact that agriculture and land use now account for almost a quarter of our emissions.

"This climate plan is a missed opportunity to deliver a progressive, sustainable and successful economy for Scotland."

Jenny Hogan, deputy chief executive of Scottish Renewables, welcomed the confirmation of the 2030 target.

But she added: "We are however disappointed to see a significant drop in ambition in decarbonising the heat sector, with the majority of effort pushed back to after 2025."

The Scottish Government is to unveil a new Climate Bill before summer 2018, with the coalition calling for a target of zero emissions by 2050 at the latest and 77% by 2030.

Green MSP Mark Ruskell said: "The published climate plan looks like ministers have used the promise of progress on electric vehicles to scale back plans to tackle fuel poverty, allow traffic to grow and avoid more ambition in agriculture.

"We need to see a resurgence in clean public transport that is genuinely run in the public interest."
