The richest 10% produce half of greenhouse gas emissions. They should pay to fix the climate | Lucas Chancel

This is not simply a rich versus poor countries divide: there are huge emitters in poor countries, and low emitters in rich countries

Let's face it: our chances of staying under a 2C increase in global temperature are not looking good. If we continue business as usual, the world is on track to heat up by 3C at least by the end of this century. At current global emissions rates, the carbon budget that we have left if we are to stay under 1.5C will be depleted in six years. The paradox is that, globally, popular support for climate action has never been so strong. According to a recent United Nations poll, the vast majority of people around the world sees climate change as a global emergency. So, what have we got wrong so far?

There is a fundamental problem in contemporary discussion of climate policy: it rarely acknowledges inequality. Poorer households, which are low CO2 emitters, rightly anticipate that climate policies will limit their purchasing power. In return, policymakers fear a political backlash should they demand faster climate action. The problem with this vicious circle is that it has lost us a lot of time. The good news is that we can end it.
