Coal Use Rises. Mercury Emissions Rise With It. The Tradeoffs Were Always Real.

What Happened

U.S. coal consumption has rebounded, reversing years of decline. As coal-fired power plants increase output, mercury emissions — a toxic byproduct of coal combustion — are rising alongside them. Mercury accumulates in waterways and fish, posing documented neurological risks, particularly to children and pregnant women.

Historical Context

This is not a new relationship. The EPA's Mercury and Air Toxics Standards (MATS), finalized in 2012, cut mercury emissions from power plants by roughly 81% between 2006 and 2020 — one of the most significant public health wins in recent environmental history. U.S. mercury emissions peaked in the 1990s and fell dramatically as coal declined and regulations tightened. Global context matters too: the U.S. accounts for roughly 3% of global mercury emissions; China, India, and artisanal gold mining together account for the majority. A coal rebound in the U.S. is a genuine reversal of progress, but it's one chapter in a much longer story that includes decades of measurable improvement.

What's In Your Control

Whether you consume large predatory fish (tuna, swordfish, king mackerel) frequently — especially relevant if pregnant or feeding young children. Whether you know your local fish consumption advisories (EPA and state health departments publish these). Whether you contact your elected representatives about energy and emissions policy. Whether you let this headline ruin your morning or use it as information.

Does This Require Action?

Awareness warranted — this is a real public health regression, not noise. If you are pregnant or have young children, check your state's fish consumption advisory. If you follow energy policy, this is a meaningful data point. Everyone else: note it, don't panic. The decades-long decline in mercury emissions shows this is a problem humans have successfully addressed before.
