BOSTON GLOBE • January 10, 2023
US planet-warming emissions increased by 1.3 percent in 2022 compared with the previous year, according to new preliminary estimates published early Tuesday morning. Leading climate scientists warn that to avert the most catastrophic impacts of climate change, the world must slash global greenhouse gas pollution by 7.6 percent each year until 2030. As the world’s top historical — and second-largest current — emitter, the United States bears particular responsibility to decarbonize quickly. But the new report by the leading independent research organization Rhodium Group, which analyzes US data on energy and economic activity for all of 2022, suggests the nation is not moving nearly fast enough.
