A small number of Ocean Rebellion protesters have gather outside Ineos in Grangemouth - Scotland's biggest polluter.
They vomited plant based water-soluble 'oil' and dressed in black theatrical costumes to represent an oil slick.
Slogans were also projected onto cooling towers which accused Boris Johnson of being 'a tool of the fossil fools'.
The demonstration, which has so far passed peacefully, did see a huge police presence though with lines of cops patrolling the site.
Sophie Miller from Ocean Rebellion said: "The Cambo Oil Field is a continuation of bowing to Fossil-fuel industry pressure, we need to wean humanity off oil not dig more wells.
"We know that Boris Johnson won’t do anything, he’s a weak-willed greedy fool.
"But the Scottish Parliament can show leadership and deliver a blow to Westminster by showing what a true environmental policy looks like."
Ineos bosses have already publicly pledged to reduce emissions to Net Zero by 2045.
There has also been a 37% CO2 reduction since INEOS took over the site in 2005.
