As global warming advances and economies become globalized, deepening certain social problems, the endurance of societies in Japan and abroad is increasingly being tested. Now more than ever, there is a need to strike a balance between environment, economy, and community, and build a sustainable society. However, there is currently no consensus as to the specific form this society should take and what issues and steps need to be addressed to acheive it, making it difficult for companies and citizens to find feasable measures to take. This project proposes we aim for an 'environmentally advanced society', giving it a different emphasis to a 'low-carbon society', and will work with a diverse range of participants, including academics and representatives from NPOs and companies, to come up with a concrete image of this society and the elements comprising it, as well as the measures that need to be taken to realize it. This will be done through workshops and online discussions, and specific, executable proposals will be compiled and released to the public. This process will also be evaluated as a participation-based policy formation process, looking at what kind of deliberative processes occured, what kind of results were produced, and what kind of information and methods proved effective, and the different steps of the process will be summarized to produce a proposal for a participation-based policy formation model program.
