绿色好事
全球现有超过一半人口在城市居住，而这个趋势仍持续上升。我们的城市已消耗全球75%的能源，是造成气候危机的一个重要因素。城市越大，就越容易受高温和豪雨影响。但我们可利用一些原创意念，令城市变得更环保、更宜居。
在哥伦比亚，城市规划师正利用绿色走廊改善空气质素，同时透过社会项目改善麦德林这个曾是贩毒据点的城市的社会氛围。
透过「系列改造」方案让旧住宅楼宇快速廉宜地更新。可持续建筑材料被用以制造备有隔温层和窗户的外墙构件，然后像第二层皮肤一样安装到旧楼宇上。用这个方法，仅在德国，每年就可以翻新650万个住宅。
波兰小镇科宁却在缺乏政府支持下推动能源转型。他们把燃煤发电厂改造为利用生物能源发电，还建成了波兰最大的太阳能发电厂。
印尼的龙目岛曾于数年前经历强烈地震，如今，人们利用以塑胶废料制成的建材兴建新校舍和新住宅。这种轻盈的建材给予人们安全感，同时亦把塑胶废料循环再造。

More than half of the world's population now lives in cities. And the trend is rising. Our cities already consume 75 percent of the energy generated worldwide and thus contribute significantly to the climate crisis. The larger the places become, the more susceptible they tend to be to heat or heavy rain. But there are original ideas we can use to make cities greener and more livable.
In Colombia, urban planners are using green corridors to improve air quality and, at the same time, social projects to improve the social climate in the former drug stronghold of Medellín.
With the "serial renovation" method, older residential buildings can be modernized quickly and inexpensively. Sustainable building materials are used to produce facade components with insulation and windows, which are then screwed onto old buildings like a second skin. Following this method, over six and a half million homes could be renovated each year in Germany alone.
The small Polish town of Konin is initiating the energy turnaround without the help of the Polish government. It is converting its coal-fired power plants to biomass and has now built Poland's largest photovoltaic plant.
On the Indonesian island of Lombok, which was hit by terrible earthquakes a few years ago, new schools and homes are being built from former plastic waste. The lightweight construction gives people more security. At the same time, plastic waste is recycled.
