Climate action requires both top-down leadership and bottom-up engagement. Drawing on five waves of the Southeast Asia Climate Outlook Survey (2020-2024; N = 7654 across 10 ASEAN countries: Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, Vietnam), this research examined how perceptions of government climate efforts relate to citizens' everyday and collective actions. Survey items were updated across years to reflect shifting geopolitical and societal conditions in the region, and cross-sectional analyses were conducted on pooled data where appropriate.


Perceiving greater government action was linked with low-friction everyday behaviors and lower likelihood of protest or disengagement. Correlations showed that those who view their governments as acting were more likely to adopt sustainable lifestyles (ρ = .12, p < .001) and follow climate news (ρ = .08, p < .001), and less likely to protest (ρ = -.03, p = .047), sign petitions (ρ = -.07, p < .001), or disengage entirely (ρ = -.03, p = .025). Moreover, such low-risk everyday actions (e.g., following news, sharing information, making lifestyle changes) were consistently widespread across ASEAN, while direct collective political advocacy were more pronounced in certain countries (e.g., Cambodia, Vietnam) though they remained uncommon relative to other climate actions overall. Third, national profiles revealed alignment and misalignment between government credibility and citizen engagement. For example, Singapore and Brunei displayed higher trust in government but lower personal advocacy, while Vietnam and the Philippines were high on both. In contrast, Malaysia, Myanmar, Laos, and Thailand clustered lower on both dimensions.


These findings illustrate how perceptions of government effort shape everyday and collective forms of climate engagement, and how distinct national contexts produce different trust-advocacy profiles. Policy implications include making government efforts visible and credible, reducing barriers to everyday engagement, and safeguarding civic space so that citizen participation complements government leadership.
