Study on the Development for Low Global Environmental Burden from the View Point of Engineering and Socio-Science.

即使只有一个国家尽最大努力解决全球范围的环境问题，也是不可能的。对于这一挑战，有必要有可持续发展的概念。东京大学目前与瑞士麻省理工学院ETH有合作研究项目，名称为“全球可持续发展联盟=AGS”，几项联合工作正在进行中。这个研究项目旨在通过提供研究人员交流的旅费来加强这些联合工作的活动，因为为了就每个问题交换意见，面对面的会议似乎是相当重要的。今年，年会在麻省理工学院举行，40多名研究人员出席并召开大会，宣传AGS的精神。除了学术界的研究人员外，工业界的一些成员也为AGS的活动做出了巨大贡献。作为一个突出的主题，对“东京半项目=THP”进行了一些描述。THP的目标是在不牺牲城市的便利性和舒适性的情况下，将东京地区的二氧化碳气体排放量减少一半。从减少二氧化碳气体的角度出发，讨论了什么样的能源系统是最优的，或者什么样的运输方式可以减少排放。还指出，我们的生活方式必须从大生产向可持续发展转变。

It is impossible to solve global scale environmental problems, even if only one nation do its best towards the solution. It is necessary to have the concept of sustainability for this challenge. University of Tokyo currently have cooperative research project with MIT, ETH (Switzerland) under the title of "Alliance for Global Sustainability = AGS", and several joint works are under the operation. This research project is to enhance the activities of these joint works by supply the travel expenses for the exchange of researchers, because it seems quite important to have "face to face" meeting in order to exchange views on each problem. This year, the annual meeting was held in MIT, and more than 40 researchers attended and held general meeting to promote the spirits of AGS. In addition to the researchers from academic field, some members from industrial sector contributed greatly to the activity of AGS. As one of prominent topics, some description is made for "Tokyo Half Project = THP". THP aims to reduce the emission of carbon dioxide gas from Tokyo area into half without sacrificing the convenience and comfort of the city. It was discussed what kind of energy system is optimum from the view point of the reduction of carbon dioxide gas, or what kind of transportation can reduce the emission. It was also pointed out that our life style must be changed from the mass-production to sustainable type.
