In 1988, the world was preparing to act against climate change. But then something happened. Something that stopped the positive movement and led to the climate crisis that the world has woken up to today. The planet's largest oil companies were among the first to detect global warming, but instead of acting they launched a campaign that for 30 years has derailed the fight against climate change. 'The Campaign Against the Climate' is an in-depth documentary that reveals how things could go so badly wrong – and who was behind it all. Through internal documents and interviews with those involved, we observe at close quarters how the oil industry for years ran an international campaign that tricked people and decision makers all over the world for years, and how it coloured the public's perception of climate change. A story that is not over yet.
