Capitalism has often been identified as the underlying cause of the climate crisis. A leading voice on the subject is Naomi Klein, one of the climate movements most influential thinkers, whose seminal book on climate change was subtitled Capitalism vs. the Climate. She is one of many voices identifying capitalism as the cause of climate change.
Often central within the capitalism versus the climate framing is the idea that the heart of capitalist ideology—free market fundamentalism—has fueled the climate crisis. But this line of argument often glosses over the fact that energy markets are not free from government intervention. In fact, the fossil fuel industry is deeply and increasingly reliant on government support to survive.
