The Greens have urged Scots to vote at the Holyrood election in May "like their future depends on it".
Co-leader Patrick Harvie warned time was running out to tackle the global climate emergency and that bold environmental policies were now required.
The Greens returned six MSPs via the list vote at the last Scottish Parliament election in 2016 and members are hoping to hit double figures this time around.
But the pro-independence party has faced repeated criticism from Unionists for being too supportive of the SNP Government.
The Greens refused to back other opposition parties last week when Deputy First Minister John Swinney faced a vote of no confidence for delays in releasing evidence to the Alex Salmond Inquiry.
Launching his party's campaign in Edinburgh today, Harvie insisted his party had "worked constructively" throughout the covid pandemic to make sure workers were protected.
He said: “Our future is at stake at this election.
"Climate science gives us just nine years to reverse climate breakdown, and the pandemic has shown up the gaps in our economy that allow too many people to fall into poverty.
“The Scottish Greens have worked constructively during the Covid crisis to make sure our frontline workers are tested regularly, to bring about a ban on evictions over winter and make sure our schools are safe.
“But as we build back from this crisis and address the looming climate emergency, we need a recovery that creates jobs and tackles Scotland’s climate emissions.
"We need investment in low carbon industries like windfarms, trains and warm homes. Only the Scottish Greens offer the solutions to act now, which is why we are asking people to vote like our future depends on it on May 6.”
