Top energy, tech, and climate researchers at ETH Zurich have engaged in an informed debate over the European regulation that sets an upper carbon footprint limit for European markets.
The limits, to be established this year, come into force in 2027 and will apply to electric vehicle batteries and stationary batteries with more than 2 kilowatt-hours (kWh) of storage capacity. In a Science paper examining this topic, researchers anticipate that any throughput-based design option for quantifying the carbon footprints of batteries may fall short of its expectations and do more harm than good.
The regulation could play a pioneering role in
