Cities are key for achieving the 1.5 °C warming limit of the Paris Agreement. However, synthesizing policy insights from the urban literature is a challenge, due to its rapid growth, breadth of topics and relative lack of assessments so far. Here we introduce methods from computational linguistics to build a systematic overview of research on transport, buildings, waste management and urban form. We find that the epistemic core of the mitigation-focused urban literature is currently centered on urban form and emissions accounting, while extensive research into demand-side options remain overlooked, including congestion and parking polices, active travel, and waste management. In the IPCC Special Report on 1.5 °C, and for meeting the target itself, all such city-scale opportunities need to be examined.

城市是实现《巴黎协定》规定的1.5°C升温极限的关键。然而，由于城市文献的快速增长，主题的广度以及迄今为止相对缺乏评估，因此综合城市文献中的政策见解是一个挑战。在这里，我们将介绍计算语言学的方法，以系统地概述交通，建筑，废物管理和城市形态的研究。我们发现，以缓解为重点的城市文献的认识论核心目前集中在城市形态和排放核算上，而对需求方选择的广泛研究仍被忽视，包括拥挤和停车政策，主动出行和废物管理。在IPCC关于1.5°C的特别报告中，为了实现目标本身，需要检查所有此类城市规模的机会。
