Activists from Extinction Rebellion Scotland block the main entrance to the Oil Rig Maintenance Facility at the Cromarty Firth Port Authority’s Invergordon Service Base.
They erected a 4.2m high oil rig made of scrap materials with a banner saying “Put me out of commission now”.
Four would also be locked on drums of propeller oil on the road, preventing access to traffic.
John Lardner (69) and Exitinction Rebellion (XR) Scotland campaigner and retired history teacher, said: ‘The Chapham House report indicates that even if the Paris Agreement carbon emissions were met , we have almost no chance of staying below pre-industrial warming levels. We must act now. Our carbon budget is empty. We do not have the choice.
The group calls for an end to fossil fuel extraction and support for a transition of skilled oil and gas workers to decommissioning and renewable industries, not new oilfields.
Other activists hold banners nearby saying ‘Climate emergency’ and ‘No future in fossil fuels’.
Maciej Walczuk (19), an engineering student, said: “We have no choice, the fossil fuel industry is already causing the deaths of the most vulnerable people on this planet.
“Places like this need to look to the future. To survive, they need to transform into work that doesn’t compromise our future instead of trying to continue to profit from the expansion of a deadly industry. “
