“Taxing flights is one way to target high emitting lifestyles, especially if we tax business class more than economy class,” Chancel told Climate Home. “A tax on air tickets to finance development programs already exists in some countries. What we need is to increase its level and generalise it.”
Piketty – author of Capital, a bestseller on wealth inequality – and Chancel outline huge disparities in people’s carbon footprints across the world. One-tenth of people are responsible for 45% of global emissions. “Economic inequalities are reaching record high levels and reducing them constitutes a key challenge to policymakers in the coming decades,” said Chancel.
“It’s the same thing with carbon: another huge challenge that puts our societies at risk. If we fail to address both, our societies can collapse.””
