Abstract
We conducted a social survey in the Japanese cities of Yokohama and Kitakyushu and classified citizens into groups regarding attitudes on climate change and developmental cooperation, identifying each group's state of support to international intercity cooperation for the environment. The survey not only collected relevant attitudinal data including attitudes on carbon crediting but provided the respondents with opportunities of carbon offsetting as remuneration to obtain real action data. The principle component analysis and cluster analysis show there are five groups in terms of preference of carbon crediting as well as interests in climate protection and international development. The group of global environment contributors, opposing carbon crediting, is most supportive of international intercity environmental cooperation while they are more active in climate protection in daily lives. This group may not support the city's obtaining credits by extending support of climate change mitigation projects in developing countries.
