Based on preliminary economic activity and energy data, Rhodium Group estimates that greenhouse gas (GHG) emissions in the US slightly increased in 2022, rising 1.3% compared to the previous year. While this is the second year in a row that emissions have increased, it nonetheless marks a change from 2021, when emissions rebounded faster than the economic growth rate. This reversal in 2022 was largely due to the substitution of coal with natural gas—a less carbon-intensive fuel—and a rise in renewable energy generation.

The effects of drought and climate change are seen at Hoover Dam, which will soon hold the smallest amount of water since it was filled in the 1930s.
