Abstract
In this study, we propose an approach to implement policies to develop a green society through achieving several environmental targets. We applied it to Putrajaya, Malaysia. Tree environmental targets were set in that case study; Low-carbon Putrajaya, 3R Putrajaya, and Cooler Putrajaya. Then we estimated necessary countermeasures to achieve the target, CO2 emission reduction by each sub-actions, and co-benefit of countermeasures to achievement of the three targets. We had workshops with stakeholders in Putrajaya to discuss sub-actions and programs to propose. This approach will help implementation of policies by enforcing suitability to that city and also taking stakeholders' opinion into consideration.
