Currently, the pricing environment favors new players. EU ETS (European Union Emission Trading System) remains the world's main and largest trading system for greenhouse gas emission credits. In the last year, its turnover was EUR 51.4 billion. During 2020, the price of CO₂ credits increased by 30%. In early 2021, emission credit futures were trading above EUR 32, and

are believed to continue going up in the medium term. The magnitude of their growth will depend on how radical the expected carbon tax in the EU turns out to be. Current forecasts vary widely. Emission credit price may vary in the range from EUR 40-70 per metric tonne of CO₂ until 2025.
