US watchdog plans to make companies reveal greenhouse-gas emissions

Climate action rules announced by SEC chair Gary Gensler expected to face opposition from Republicans and industry groups

The US's top financial watchdog proposed on Monday that publicly traded companies report information on their greenhouse-gas emissions and even those of their suppliers and consumers in one of the Biden administration's most sweeping environmental actions to date.

The new Securities and Exchange Commission (SEC) rules faces staunch opposition from some politicians and members of the business community and will be open to public comment for at least two months before final rules are released.
