从城市大都市碳足迹的原始数据集，我们探讨了国家层面的气候变化承诺和次国家层面的库存之间的相关性。我们问：自愿报告是否允许一个城市的表现优于全国平均水平？承诺中的雄心是否对减少足迹的绩效有影响？长期承诺是否会影响减少足迹的绩效？具有约束力的国家一级承诺（如《京都议定书》下的承诺）是否影响城市一级在减少足迹方面的表现？为了提供答案，我们综合了来自世界各地最大的自愿性次国家承诺和行动库的数据，以减少足迹和温室气体清单，Carbonn平台。超过500个城市向该数据库报告至少一项行动、承诺或库存。我们发现，使用这个数据库的一个子集，也许与直觉相反，具有更雄心勃勃的承诺的城市不一定有更大的减排量。我们的数据还表明，拥有长期自我报告的目标并不能使城市在减少足迹方面表现得更好。据报告，政府和社区的承诺似乎都是如此。最后，积极的一面是，我们的数据确实揭示了对属于承诺遵守《京都议定书》的国家的城市的统计学显著影响，这表明有必要约束国家（和超国家）气候目标。
Drawing from an original dataset of urban metropolitan carbon footprints, we explore the correlations between national level climate change commitments and sub-national level inventories. We ask: Does voluntary reporting allow a city to perform better than national average? Does ambitiousness in commitment have an impact on performance in footprint reduction? Does having long-term commitments affect performance in footprint reduction? Do binding national level commitments (such as those under the Kyoto Protocol) affect performance at the city level in terms of footprint reduction? To provide answers, we synthesize data from the largest repository of voluntary sub-national commitments and actions towards footprint reduction and greenhouse gas inventories from around the world, the Carbonn platform. More than 500 cities report at least one action, commitment or inventory to this database. We find, using a subset of this database, perhaps counter intuitively that cities with more ambitious commitments do not necessarily have steeper reductions in emissions. Our data also suggest that having long-term self-reported goals does not make the cities perform better in terms of footprint reduction. This appears to be true for both government and community commitments reported. Lastly, and positively, our data did reveal a statistically significant effect for cities belonging to countries that had committed to the Kyoto Protocol, suggesting the necessity of binding national (and supranational) climate targets.
