Emissions Report: Cars Are Still the Biggest Problem

United States greenhouse gas emissions are down —but it’s not because anyone’s driving any less.

Overall carbon emissions were down two percent in 2019, but pollution from the transportation sector — the leading contributor to climate change remained basically unchanged, though no longer increasing as it has every year since 2012.

Last year was the third straight year that transportation emissions remained above power sector emissions, which have been falling, according to the Rhodium Group. Electricity and heat production had been the planet’s biggest pollution problem for more than 60 years.
