THE TOP FIVE

1. U.S. power sector emissions rose by 4% last year

Emissions from the United States’ electrical sector spiked 4% last year as demand for power drove up generation from coal. That’s according to the latest annual assessment published Tuesday morning by the U.S. Energy Information Administration. The report, which has tracked annual emissions data from all power sources since 2010, found that U.S. energy-related carbon dioxide emissions increased by 2%, or about 115 million metric tons, in 2025. But the power sector specifically saw a surge of 4%, or 58 million metric tons, due to a spike in fossil fuel use. Coal-fired generation rose by 13%, even as natural gas-fired power fell 4%. Renewables helped avoid more coal use. While wind generation increased 3%, solar skyrocketed by 34%. Generation from all other sources — including nuclear and the category of “other renewables” that includes hydropower and geothermal — were essentially flat last year.

1. Trump imposes 50% tariffs on Canada

President Donald Trump’s on-again, off-again feud with America’s northern neighbor is, as of Monday, back on again. The White House imposed 50% tariffs on most Canadian goods, accusing the nation’s geographically nearest ally and closest cultural bedfellow of unfairly discriminating against American automotives, alcohol, and dairy products. The move threatens to unleash what the Associated Press called “a new wave of economic chaos, with risks of higher inflation and further fraying of relations between two nations that had been closely woven together before Trump’s return” to office.
