The financial burden of tackling climate change will fall disproportionately on Scotland, the financial watchdog has warned.

The Scottish Fiscal Commission (SFC) said it would cost the public sector £1.1bn a year - 18% of the Scottish government's capital budget.

Environmentalists and economists say this is still cheaper than doing nothing - which would result in more having to be spent on the impacts of climate change, such as flooding, in the long term.

The Scottish government has already urged Westminster to provide more funding for important measures like tree planting.

The £1.1bn bill relates to the commitment to reach "net-zero" in Scotland by 2045 and for the UK as a whole by 2050.

That is the point where we will have reduced our planet warming greenhouse gas emissions close to zero, with the remainder being offset by things like trees which absorb carbon dioxide from the atmosphere.

The figures do not include spending on adapting to more extreme weather events by building more flood defences, for example.

SFC said the financial burden may fall disproportionately on the Scottish government because a greater share of the UK's overall commitments fall to tree planting in Scotland.

That equates to £207 per person in Scotland compared with £149 in the rest of the UK.
