This research program will develop methods to measure, quantify and analyze emissions of greenhouse-gases (GHG) in cities. We will directly quantify emissions of carbon-dioxide (CO2), methane (CH4) and nitrous oxide (N2O) at scales of neighborhoods or land-use zones. At those scales, where most planning decisions are made, estimated emissions (from consumption statistics or aggregated by modeling) are associated with large uncertainties. There is a lack of in-situ methods and data to independently validate modelled emissions.

该研究项目将开发测量、量化和分析城市温室气体排放的方法。我们将直接量化二氧化碳（CO2）、甲烷（CH4）和一氧化二氮（N2O）的排放量，以社区或土地利用区域为尺度。在这些尺度上，大多数规划决策都是在这些尺度上做出的，估计的排放量（来自消费统计或通过建模汇总）具有很大的不确定性。目前缺乏能够独立验证模拟排放的原位方法和数据。
