US Litter Drops 34% Since 2020, Study Finds

The trash problem everyone thought was getting worse is actually getting better. Keep America Beautiful just released the largest litter study in US history, and the results show something remarkable: Americans have cut litter by more than a third in just four years.

The numbers tell a story of real change. Roadway litter dropped 22%, falling from 23.7 billion pieces to 18.4 billion. Waterways saw an even bigger win, with litter plummeting 45% from 25.9 billion to 14.2 billion pieces.

That means the average American's share of litter along roads and waterways fell from 152 pieces to just 96. For anyone who remembers highways lined with trash in the 1970s and 80s, this represents a quiet victory decades in the making.

The credit goes to multiple forces working together. Better waste infrastructure, stronger local cleanup programs, consistent public education, and growing engagement from businesses and governments have all played a role. Nearly 90% of Americans now feel personally responsible for reducing litter, according to the study.

The Ripple Effect

The decline reflects how American habits are changing in unexpected ways. Pandemic mask and glove litter has dropped 76% as COVID precautions faded. Online shopping has driven cardboard litter up 50%, but overall plastic litter is actually declining.

"This study proves what we've always believed: litter is solvable when people, systems and partners work together," said Jennifer Lawson, President and CEO of Keep America Beautiful.

The study did uncover one troubling hotspot. Coastal areas contain 8 to 13 times more litter per mile than inland environments, a finding that's pushing communities to develop targeted beach and shoreline strategies.

Even with 35 billion pieces of litter still scattered across America, the trend line points toward hope. What once seemed like an unfixable problem is proving that consistent effort, public commitment, and smart systems can turn the tide on even the most visible environmental challenges.
