LONDON — With Earth Day on the horizon, Gallup research shows that the world feels more positive today about efforts to preserve the environment than at any point in the past 20 years, even as many global environmental indicators point to worsening conditions.
In 2025, a median of 57% of adults across 140 countries said they are satisfied with environmental protection efforts in their country, while 41% said they are dissatisfied. Satisfaction has increased significantly since 2022, rising eight percentage points from 49%. For much of the 2010s, satisfaction with environmental preservation efforts was broadly stable, near 50%.
Though most of the world feels satisfied with environmental preservation efforts, less than half of adults in 50 countries agree, including in the United States.
