“Culture + Climate Change” activity is a cultural program launched by Goethe-Institut China in 2010. As an important component of the activity, “green environmental protection diary” invited every participant to write their low-carbon life diary, so as to let every record becoming the process of self-supervision and reminder. 
Diary design also takes its practical and communicational functions into consideration. The thickness and size of this diary is based on portable rule, and its material is delightful, friendly.Carbon-emission list is designed for easy inquiry. Thumb movie allows users to see the direct relationship between their low-carbon life and the benefits for little trees to grow into big trees. This activity has provided recorders with an interesting writing experience. 
 “文化与气候变迁”（Culture + climate changes）活动是2010年北京德国文化中心·歌德学院（中国）发起的文化项目，开展跨学科的全球探讨，同时开启了环境保护对话的新视角。
绿色环保日记作为“文化与气候变迁”的重要组成部分，邀请每一个参加活动的人带着孩子般善于观察和发现的心，一起来写绿色环保日记，让每一次记录都成为自我督促和提醒的过程，在潜移默化中形成低碳环保的习惯。
环保日记在设计时考虑其实用和传播功能。在实用功能方面，开本薄厚便于携带，图形和材质富有亲和力；传播功能的设计上，碳排放表格信息易于查询，让记录者很清晰知道身边方方面面与生活有关的碳排放指数，拇指电影功能可看到自己低碳生活与小树长成茂盛大树的直接关系，进而能快速感受保护环境、气候变迁和我们的生活息息相关，给记录者提供了一次有趣的书写体验。
