The purpose of this thesis is to understand how a communitybased carbon credit could be implemented through the use of social capital. As such, it is a practical exploration into the relationship between classical economics and a humanitarian design approach. The thesis is carried out in 2 sections. Part one analyses how the existing credit model fails to relate to human behaviour on 3 fundamental levels. These levels include issues of measurement standards, proximity of credits generated and the human condition in relation to the carbon economic model. From there, I will explore the use of social capital and the potential to supplement a personal credit framework within a community context. The second part outlines the design proposal for implementing a carbon credit system on a community level. The proposal will consist of an urban intervention, an online social platform and the physical implementation of the online data within an urban setting.
