解决中国污染问题的答案在日本

    东京市政府已经和北京市政府在废物及废水处理领域进行技术交换。东京是世界上规模最大的城市，建有全球技术最先进的污水处理和循环利用系统之一。借助这样的技术，东京在联合国（United Nations）清洁城市榜上的排名从末尾一跃进入了领先者的行列。

    日本第二大城市大阪也希望为中国提供浮式太阳能水净化器。这种设备每天可净化2,400升水，正用于大阪受到污染的运河系统

    虽然近期日本在环保方面并不是毫无问题，但日本的技术专家乐观地认为，日本的其他绿色技术能引起中国的兴趣，比如最近开发的智能城市系统。它有助于促进可持续性规划和发展。就连川崎，这个日本工业迅猛而无节制增长所产生的“肮脏老城”如今也在通过每年一次的生态博览会向全世界推广本地开发的环保技术，而且还建有日本最大的太阳能发电站。

    中国的情况可能不会那么容易发生改观。尽管日本的绿色科技产业可能会得到中国官方的支持，但实际情况可能会证明，中国的国企和地方利益并不像20世纪80年代日本的工业界那么容易对付。尽管存在成本问题，但是归功于持续不断的社会压力，经过长时间的较量，日本工业界最终还是接受了20世纪70年代颁布的《大气污染防治法》所提出的要求。中国存在污染问题，但依然能够赚到利润。因此，如何说服中国采用日本昂贵的污染防治新技术，可能会成为日本面临的又一项任务。（财富中文网）

    Tokyo and Beijing city governments already cooperate through a technical exchange in waste and water management. Tokyo, the biggest city in the world, already has one of the most technologically advanced sewage and recycling systems anywhere. Such technology helped pull Tokyo out of the bottom of a United Nations list for clean cities to a place near the top.

    Japan's second city, Osaka, meanwhile wants to offer up its floating, solar-powered water purifiers that can each clean 2,400 liters per day in its sullied canal system.

    Although Japan's recent environmental record is not without blemish, the country's technocrats are bullish that it can interest China in other green technologies such as its recently developed smart cities that help promote sustainable planning and development. Even Kawasaki, the "dirty old town" product of Japan's spectacular, but unregulated industrial growth, now boasts an annual Eco Fair which promotes its homegrown environmental technologies to the world and is now host to Japan's largest solar power plant.

    Changes in China may not come so easily. The Japanese green tech industry may have official China on its side, but state-owned corporations and local vested interests could prove less tractable than industrial Japan of the '80s. After a long fight, Japanese industry eventually buckled under Japan's clean air acts enacted in the '70s, despite the costs, thanks to persistent social pressure. Persuading a dirty but profitable China to take up Japan's expensive new antipollution technologies may prove another task altogether.
