Holyrood politicians are campaigning for their pensions to come from “ethical investments” rather than fossil fuel companies.
The MSP pension fund currently invests at least £1m in oil, gas and coal companies, according to Friends and Earth Scotland.
Now a cross-party group of MSPs have spoken out on the issue ahead of a meeting of their pension fund trustees.
A parliament spokesman said they were reviewing their investment strategy.
The move comes after First Minister Nicola Sturgeon declared a “climate emergency” at the SNP party conference earlier this year.
There is growing pressure from environmental campaigners for public bodies to move their investment into greener companies, also referred to as divesting.
