Scotland should set an emissions reduction target of 61% by 2030.
That’s the recommendation of the Climate Change Committee (CCC) which added a fall of at least 3% of emissions every year from 2020 would be necessary.
If the target is met, Scotland would be able to reach an emissions reduction of 80% by 2050, it stated.
The Committee believes the country’s ambition is higher than the UK as a whole and suggests a framework to help achieve the target.
It recommends installing heat pumps in around 18% of homes by 2030 and electric vehicles should account for 65% of new car and van sales by 2030.
Electricity decarbonisation should also reduce emissions from 220 gCO2/kWh to below Scotland’s legislated target of 50 gCO2/kWh, it added.
The Committee suggests a revision to the Scottish targets for 2027 to align them with the latest scientific evidence on past emissions and accounting rules for the EU Emissions Trading System.
Lord Deben, Chairman of the CCC said: “Scotland is leading the UK in its ambitious approach to tackling climate change and is to be commended for doing so. There is a lot of positive action already underway in Scotland, driven by both its vibrant renewable sector and its bold policy approaches. This must now be accelerated.
“New policies will be required to meet these ambitious but achievable carbon objectives. With these actions Scotland can continue as an example to the rest of the UK in its approach to address climate change.”
The Scottish Government said the advice from the CCC will be taken into account when Scotland’s next batch of targets are set in October.
Climate Change Minister Aileen McLeod said: “Scotland is a world leader in tackling climate change, with our approach being described as ‘exemplary’ by Christiana Figueres, the head of the UN climate body, during her visit to Scotland last week. We are on track to exceed our 2020 target for a 42% reduction from baseline levels in greenhouse gas emissions and have outperformed the UK as a whole in every year since 2010.
“Looking to the future, I recognise the need to need to maintain our high ambition – especially following the global agreement reached as we hoped and argued for in Paris. ”
In February the CCC also warned the UK could not meet its climate targets without investment in carbon capture and storage (CCS).
