The SNP-Greens deal, signed in 2021, brought the Green Party into government for the first time anywhere in the UK.

It also gave the SNP a majority at the parliament at Holyrood when the votes of its MSPs were combined with those of the seven Greens members.

Without it the SNP would need to operate as a minority administration.

The reports Thursday come after the devolved government in Edinburgh announced on April 18 that it would scrap its target to reduce carbon emissions by 75 percent by 2030 after the UK's climate change advisory committee described it as "beyond credible".

The Scotsman newspaper reported that First Minister and Scottish National Party leader Humza Yousaf took the decision to end the agreement after calling an emergency cabinet meeting.

The Scottish Greens are currently junior partners in Yousaf's pro-independence government.

The decision to row back on its climate ambitions is the latest setback for the SNP, which has been hit by internal squabbling, resignations and a fall in support before this year's UK general election.

As part of the deal, Greens co-leaders Patrick Harvie and Lorna Slater were made junior ministers in the Scottish Government.

The UK Climate Change Committee (CCC) last month sharply criticised Scotland for repeatedly failing to achieve its climate targets.

The required acceleration in emissions reduction in Scotland was now "beyond what is credible", due to inadequate efforts in areas including home heating, transport, farming and nature restoration, it said.

Yousaf vowed that the country would still meet its target of reaching net zero by 2045.
