Coal power emissions in the EUETS were 6% higher in 2022 than in 2021, but remained lower than 2019 levels. As the energy crisis continued and fossil gas prices reached unprecedented highs in 2022, Europe was faced with a twin crisis of unexpected nuclear outages and a 1in500 year drought causing hydro output to plummet. The impact of this ...
