Over the past year, carbon revenues increased 18% from the previous year and three times higher compared to 2016.
These are distributed in US $ 29,500 million through carbon taxes and US $ 27,300 million in the quota market.
Behind these revenues, there is great heterogeneity in the prices of CO2 emissions.
“More than 46% of the emissions regulated with a carbon price have a price of less than 10 dollars a ton”recall the study authors.
According to them, this represents a price that does not coincide “with the international scientific consensus that considers that the full effect of incitement of these mechanisms is achieved with prices of between 40 and 80 dollars per ton.”
“This should make us ask about coherence,” says Marion Fetet, who recalls that, on the one hand, administrations tax emissions, but on the other, they subsidize fossil fuels.
“Subsidies for fossil fuels accounted for a minimum of $ 450 billion in 2020”, highlights the study.
On the other hand, the wealthiest people pollute much more than the poorest on the planet, and they should pay specific taxes to compensate it, according to a study by the World Inequality Lab (WIL) published on Wednesday, before the COP26 climate summit.
The richest 1% in the world emitted an average 110 tons of CO2 per person in 2019, details the study carried out by economist Lucas Chancel, co-director of WIL at the Paris School of Economics.
This represents 17% of global emissions for that year. All of these come from the consumption and investment habits of this category of the population, according to the WIL.
In addition, while the richest 10% of the world generates half of the planetary emissions, the poorest half of the population is barely responsible for 12% of the global, an average per person of 1.6 tons of carbon per person.
