Abstract
Carbon prices soared above €60/tonne for the first time on August 30, 2021, with the expectation of tightened environmental legislation. These prices made a new record on the European Union Emission Trading System (EU ETS), the European Union’s carbon market. The stressed gas market and expectations of a tighter gas supply in Europe are also behind rising carbon prices. These factors spilled over into electricity prices, which also broke highs, hitting €140 per megawatt hour (MWh) in real-time trading on September 1, 2021.
