A global competition has been launched, inviting architects to propose innovative solutions that tackle urban density and climate change in different parts of the world. Pictured here, a past entry for the city of Paris. La Ville multi-strate  (The Multi-Layered City), a concept by Jacques Ferrier Architectures, Chartier Dalix Architectes, SLA Paysagistes is a project spanning the belt road and thus connecting Paris and its suburbs.

如果你把一个成功的城市实验，来自世界各地的19个城市和19个具有可持续性意识的市长结合起来，你会得到什么？改造城市是一项全球性倡议，邀请建筑师通过创造性地重新想象我们城市中被忽视的部分，探索应对气候变化和城市密度挑战的不同方法。

这是一场前所未有的国际竞争，旨在“刺激可持续发展，并庆祝应对环境和城市挑战的创新解决方案”，它背后的组织者解释说，C40是一个致力于应对气候变化的世界特大城市网络。该项目最初的迭代项目“改造巴黎”是两年前在法国首都策划的，取得了惊人而鼓舞人心的成果；因此，C40将该项目推广到世界各地更多的城市中心，感觉很自然。

参加比赛的城市包括奥克兰、开普敦、芝加哥、休斯顿、迪拜、利马、马德里、墨西哥城、米兰、蒙特雷、奥斯陆、巴黎、波特兰、基多、雷克雅未克、里约热内卢、萨尔瓦多、旧金山和温哥华。建筑师已被邀请提交他们的兴趣，设计，想法和创新的解决方案，为选定的一些预先确定的地点在这些城市。

最后一份名单将从这些提交的文件中选出，这将为每一个未充分利用的网站提出最终的中标方案。这不是理论上的竞争；事实上，参与的团队将竞争购买或租赁网站，并实施他们的项目。

认为是地方性的，全球性的，是21世纪的心态.巴黎市长兼C40主席安妮·希达尔戈(AnneHidalgo)说，通过发起这场全球竞争，我们让这一理念非常具体地庆祝了应对环境挑战的最具活力的创新解决方案。“城市的改造将为城市的可持续发展设定新的标准，还有谁比我们的公民更能想象城市的未来呢？”我相信，这些获奖的项目将给我们所有人带来惊喜，并带来我们今天无法想象的创新。

总冠军将于2019年年初公布。结果是什么呢？主办方说，这场比赛将成为世界各地城市的典范，展示城市与企业之间的联盟如何塑造未来，实现更健康、更环保和经济上可行的城市发展。
