WASHINGTON — Climate-altering pollution from greenhouse gases declined by nearly 2% in the US in 2023, even as the economy expanded at a faster clip, a new report finds. The decline is far below the rate needed to meet Joe Biden’s pledge to cut U.S. emissions in half by 2030, compared to 2005 levels, said a report. “Absent other changes,″ the U.S. is on track to cut greenhouse gas emissions by about 40% below 2005 levels by the end of the decade, said Ben King, lead author of the study. The report said U.S. carbon emissions declined by 1.9% last year. Emissions are down 17.2% from 2005. …Last year’s relatively mild winter and continued declines in power generation from coal-fired plants drove down emissions in the US. …Turning the tide on industrial emissions will also require meaningful action to decarbonize other industries such as iron and steelmaking, cement manufacturing and chemical production, the report said.
