How high should the price of a tonne of CO2 be to have an impact?

It is very hard to put an accurate price on all the damage climate change causes. How do you put a price on the loss of biodiversity, ocean acidification, sea level rises, extreme weather, drought, famine, the spread of tropical diseases, political instability and other effects we didn't even yet think of?

Prominent economists [1] involved in the 'High-Level Commission on Carbon Prices'[2] calculated that we need a price between €35 and €65 per tonne of CO2 in 2020 and between €40 and €80 per tonne of CO2 in 2030 to be in line with the Paris Agreement objectives.

For the current price of one carbon credit, check the German trade platform EEX, which is designated by the European Commission to be the joint auction platform.
