①Whether it’s the distinctive Shard skyscraper in London or the World Trade Center in New York, modern structures rely on cement and steel. 无论是伦敦与众不同的Shard摩天大楼，还是纽约的世贸中心(World Trade Center)，现代建筑都依赖于水泥和钢材。

②And while those materials may look benign, making each involves chemical processes that throw off tons of carbon dioxide in addition to the energy they consume. 虽然这些材料看起来是无害的，但制造每一种材料都需要进行化学处理，除了消耗能量外，还会释放出大量二氧化碳。

③Construction is responsible for 11% of global carbon emissions, according to a report from C40, a group of leading metropolitan authorities. 根据C40的一份报告，建筑占全球碳排放的11%。 

④Those figures underscore how efforts to rein in greenhouse gases will touch almost every part of the economy. 这些数字突显出，控制温室气体排放的努力将触及经济的几乎所有领域。

⑤After concentrating on the energy industry, policymakers now are scrutinizing buildings as a major source of pollution, prompting companies from steelmaker ThyssenKrupp AG to cement supplier LafargeHolcim Ltd. to look for greener alternatives. 在把注意力集中在能源行业之后，政策制定者现在开始把建筑作为一个主要的污染源来审查，这促使钢铁制造商蒂森克虏伯公司(ThyssenKrupp AG)和水泥供应商LafargeHolcim Ltd.等公司寻找更环保的替代品。
