Ferry media; terminal and on-board advertising Accusations of climate change denial In 2011, Pattison Outdoor Advertising disallowed Beyond Coal, who had bought billboard space on one of the company's billboards, from displaying an anti-coal message until references to the nearby Westshore Terminal, where 700 train cars of coal are loaded each day, were removed. In 2012, Greenpeace were engaged in talks with Pattison Outdoor Advertising to display a billboard advocating renewable energy sources, but the company abruptly terminated the discussions. When asked why the billboard would not be approved, the company refused to provide a reason. In 2014, Pattison Outdoor Advertising allowed Friends of Science to place a billboard opposed to the scientific consensus on climate change, which prompted organizations like Greenpeace to accuse Pattison Outdoor Advertising and the Jim Pattison Group as a whole of applying a double standard and censoring environmentalist messages.
