Green stocks have generally outperformed brown stocks in terms of returns over the past decade, according to a new study. The study used CO2 emissions as a measure of a company's greenness and found that green stocks across the G7 have provided higher returns. The authors also attempted to reconcile their findings with previous research and provided some results for early 2022, which showed that brown stocks outperformed green ones during the energy crisis. The study was funded by the Deutsche Forschungsgemeinschaft.
