Arctic cities face unique challenges in managing their solid waste due to their relatively small size, remote location, extreme and rapidly changing climate, and boom-bust economies. We compare solid waste management practices across Arctic and non-Arctic cities employing the International Standard ISO 37120 Sustainable cities and communities - Indicators for city services and quality of life, published by the International Organization for Standardization in 2018. Generally, Arctic residents produce more waste annually (0.62 tons per capita versus 0.3 tons per capita globally), while seeing lower rates of collection (90% versus 100% in many but not all cities) and recycling relatively little compared to other cities (11% on average versus 20% globally), though there is considerable variation both north and south. In contrast to other areas, economic development does not explain the amount of waste generated by Arctic residents, though city wealth does provide some explanation for solid waste management practices. Most importantly, we found that in the far north, high levels of political participation correlate strongly with better waste management practices. Methodologically, we conclude that ISO 37120 is a useful metric because it is comparable across cities, relatively easy to measure, and offers a growing store of city-level data on waste and sustainability measures that help to explain differences in waste management practices across cities. To improve on existing conditions, Arctic cities should prioritize implementing methods to reduce waste production and increase recycling.
由于规模相对较小、地理位置偏远、极端且快速变化的气候以及繁荣-萧条的经济,北极城市在管理固体废物方面面临着独特的挑战。我们使用国际标准化组织(ISO)2018 年发布的《可持续城市和社区-城市服务和生活质量指标》(International Standard ISO 37120)比较了北极和非北极城市的固体废物管理实践。一般来说,北极居民每年产生的垃圾量更多(人均 0.62 吨,而全球人均 0.3 吨),而收集率较低(90%,而许多城市不是 100%),与其他城市相比,回收相对较少(平均 11%,而全球平均 20%),尽管南北差异很大。与其他地区不同,经济发展并不能解释北极居民产生的垃圾量,尽管城市财富确实为固体废物管理实践提供了一些解释。最重要的是,我们发现,在遥远的北方,较高的政治参与度与更好的废物管理实践密切相关。从方法论上讲,我们得出结论,ISO 37120 是一种有用的指标,因为它在城市之间具有可比性,相对容易衡量,并且提供了越来越多的城市层面的数据,这些数据有助于解释城市之间废物管理实践的差异。为了改善现有状况,北极城市应优先考虑实施减少废物产生和提高回收利用率的方法。
