Meanwhile First Minister Nicola Sturgeon accused Jeremy Corbyn of trying to "mislead" voters on the single market ahead of a crucial House of Commons vote that is set to re-open Labour's divisions on Brexit.
The Scottish Government's study, launched by Ms Sturgeon in Edinburgh today, looks at the impact of three different Brexit outcomes on GDP, trade and immigration.
"Evidently, Brexit continues to cause real uncertainty across our society, and SCVO has made clear from the outset that we think leaving the European Union will be bad for Scotland and Scotland's charity sector - exacerbating already hard circumstances for charity organisations and the individuals and communities they seek to empower", said acting chief executive Lucy McTernan.
Panic as alert unnerves Hawaii
Hawaii US Senator Brian Schatz tweeted the false alarm was "totally inexcusable" and was caused by human error. Even hours after the false alert was sent, the islands were still reacting to the earlier scare.
In the months after the EU vote, Ms Sturgeon called for a second referendum on Scottish independence - there had been a "material change" of circumstances in the 2014 vote when pro-Union campaigners warned Scots they would lose their EU membership if they voted "Yes". However, the United Kingdom government has already ruled out remaining part of the market.
That was "absolutely, manifestly, beyond any doubt the option which will do the least damage to our economy", Sturgeon said.
She said: "It's time for her to stop listening to the discredited voices around her Cabinet table and start listening to the overwhelming case for Single Market membership".
Sturgeon said the research will detail how remaining in the European single market and the customs union would be the least damaging option for the United Kingdom economy.
'Bad deal' embassy; Donald Trump cancels United Kingdom trip
Trump has also been offered a full-blown state visit to Britain but no date has been set, amid jitters over protests. Trump had responded by tweeting directly to the British PM that she should focus on tackling domestic terrorism.
The move follows a Brexit summit by the leaders of the four parties which Labour refused to attend.
The Scottish Council for Voluntary Organisations (SCVO) has said that the publication of Scotland's Place in Europe highlights the need for the United Kingdom to remain within the single market and customs union. "By far the best option for the Scottish economy is to stay in the EU". This variant of Brexit would see the Scottish GDP 2.7 percent less in 2030 (£688 per head).
The MP for Ilford North in London said Labour's calls for a "jobs-first Brexit" that secures "tariff-free access" to the European Union while leaving the single market was a "fudge" for the 2017 general election that "will not carry us through 2018".
"The fact that the Prime Minister wants to leave not only the political structures of the EU but come out of the European Economic Area shows just how extreme the UK Government position is".
Detroit Lions likely to land Matt Patricia as head coach
It was only a matter of time before news leaked about where Patricia would end up in 2018. Caldwell went 36-28 as the Lions head coach, with an 0-2 playoff record in four seasons.
