This paper analyzes citizens’ eco-awareness between Toyota City in Japan and Neiva City in Colombia. Both cities have been making efforts to promote their eco-policies, which are somewhat similar to each other in areas such as transportation and public welfare and livelihood. To put these policies into practice, civic support is essential. Through survey questionnaires, this study compares citizens’ awareness of eco-policies in Toyota City and Neiva City. Findings show that Toyota City outperforms Neiva City in some areas such as forests and the urban center while Neiva outperforms in other areas: transportation and industry. This paper explains possible reasons for these differences and makes suggestions to further promote eco-policies.
