Americans are making measurable progress in the battle against litter, according to extensive new research that documents a 34% decline in debris across the nation since 2020. The findings, released by the charity Keep America Beautiful, represent the most comprehensive litter study ever conducted in United States history.
The study reveals that every American's share of litter along roadways and waterways has fallen from 152 pieces to 96 pieces over the four-year period. This translates to roadway litter declining 22% from 23.7 billion to 18.4 billion pieces, while waterway litter experienced an even more dramatic 45% reduction from 25.9 billion to 14.2 billion pieces.
Jennifer Lawson, President and CEO of Keep America Beautiful, attributed the progress to coordinated community action. "This study proves what we've always believed: litter is solvable when people, systems and partners work together," Lawson stated. "The declines show us what's possible when communities act with urgency and commitment."
The research identifies several driving factors behind the improvement: education initiatives that shape public behavior, robust local programs with enforcement mechanisms, enhanced infrastructure providing better access to waste management systems, and increased engagement from businesses, organizations, governments, and individual citizens.
Public sentiment supports continued action. Survey data accompanying the study shows nearly 90% of Americans feel personal responsibility to reduce litter, while 93% agree it represents a shared community responsibility. These attitudes appear to be translating into tangible behavioral changes across the country.
The study also captures how litter patterns reflect evolving American lifestyles. Cardboard litter has increased 50% as online shopping continues to reshape consumer habits. Personal protective equipment litter—masks and gloves that surged during the pandemic—has declined 76%. E-cigarette litter has spiked alongside vaping trends, while overall plastic litter is declining.
David Scott, PhD, SVP of Data and Research at Keep America Beautiful, emphasized the diagnostic value of litter data. "Litter tells the story of how we live," Scott explained. "Right now, it's telling a story of progress, but it's also showing us exactly where we need to focus next."
The research introduces new insights into coastal litter density, estimated nationally for the first time. Coastal zones contain 8-13 times more litter per mile than inland environments, highlighting a critical area requiring targeted intervention strategies.
Despite the encouraging trends, significant challenges remain. With 35 billion pieces of litter still present across American landscapes and new types of debris emerging, Keep America Beautiful emphasizes the need for sustained effort. Lawson cautioned that without continued commitment and smarter strategies, recent gains could be reversed.
The study, which updates the groundbreaking Keep America Beautiful 2020 National Litter Study, serves as both a progress report and a roadmap for future action as the country approaches its 250th birthday. It provides communities with data-driven guidance on where urgent intervention remains necessary and demonstrates the effectiveness of coordinated anti-litter efforts.
The research underscores a fundamental principle: environmental improvement requires collective action sustained over time. The 34% reduction in litter since 2020 proves that when communities mobilize around shared goals with adequate infrastructure and public engagement, measurable progress becomes achievable.
