US greenhouse gas emissions rose sharply in 2021: Report

US' greenhouse gas emissions from energy and industry sharply rose 6.2% in 2021 after a pandemic-driven decline in 2020, according to a report by the Rhodium Group. The surge has put US further off track from its climate targets. The emissions majorly increased due to jump in coal-fired power generation and a "rapid rebound" in road transportation, the report said.
