In 2021 banks pocketed US$3.4 billion from green-labelled debt deals, compared with US$3.3B from their work with oil, gas and coal companies. In 2020, the split was US$1.9B for green and US$3.7B for fossil fuels. Analysts expect that US$2.5 trillion of debt advertised as green or ESG-oriented will be issued this year, up from US$1.5T in 2021.
