In his 2020 book The Citizen's Guide to Climate Success: Overcoming Myths That Hinder Progress, Mark Jaccard is critical of Klein's assertion that capitalism must be abolished in order to solve the climate crisis. Instead Jaccard asserts that solving climate change is completely possible in capitalist economies and that all progress on climate thus far has been made in mixed-capitalist economies. He says that abolishing capitalism is actually only Klein's preferred path to solving climate change and not essential to solving climate change as Klein declares.
