Carbon Price (EU ETS)

Get the price of emitting one tonne of CO2 under the EU Emissions Trading System (EU ETS): the clearing price of the primary auctions of EU emission allowances (EUAs) the European Energy Exchange holds for the European Union, Germany and Poland almost every trading day, daily from 2020. The carbon price is the main transition risk variable of climate scenarios; see get_climate_scenario for its projected paths.

The price is the average of the day’s auctions of general allowances, in euro per tonne of CO2. No API key is needed. Weekly and monthly periods take the price of the last auction of each period.
