Air quality is significantly affected by levels of economic activity and wider patterns of industrial and domestic consumption. Whilst lower air pollution was frequently reported as a short-term consequence of lockdown, less well quantified are the potential longer term improvements in urban air quality that may arise from more sustained shifts in behavioural patterns during the recovery phase and beyond. For example, these may arise from changed commuting modes, office and school times, and continuation of homeworking. Altered air pollution emissions in cities, even if only sustained for a few years, may deliver disproportionately front-loaded benefits. As the UK transitions towards transport electrification and older vehicles leave the fleet, it is in the years immediately following the pandemic that the largest benefits to air quality are likely to be felt. Lower air pollution during the lockdown phase of the pandemic was not surprising, with NO2 falling widely across the UK. More surprising has been the recent divergence between increasing traffic volumes and the rebound in pollution as restrictions on society have lifted. Understanding the mechanisms behind this, and the potential air quality and public health opportunities, lies at the heart of this proposal. This research is ideally conducted at a time once most the significant lockdown restrictions have been lifted and specifically once schools (and their related transport have resumed). It is therefore timed to begin towards the end of 2020. The real-world impacts of this research may be highly significant, allowing an evaluation changing urban emissions regimes.

空气质量受到经济活动水平以及工业和国内消费的更广泛模式的显着影响。尽管经常报告较低的空气污染是锁定的短期后果，但量化较少的是，在恢复阶段及以后行为模式的持续变化可能会持续的持续变化可能导致的城市空气质量的潜在长期改善。例如，这些可能是由于变化的通勤模式，办公室和学校时代以及家庭作业的延续而引起的。城市的空气污染排放的改变，即使仅维持了几年，也可能带来不成比例的前部福利。随着英国向运输电气化和旧车辆的过渡离开舰队，在大流行之后的几年中，可能会感受到最大的空气质量好处。在大流行期间的锁定阶段，空气污染降低并不奇怪，在英国，No 2占据了广泛的趋势。更令人惊讶的是，由于对社会的限制，交通量增加与污染的反弹之间的差异。理解这背后的机制以及潜在的空气质量和公共健康机会，这是该提议的核心。理想情况下，一旦大多数大多数重要的锁定限制都被取消，尤其是学校（及其相关运输恢复），就可以进行这项研究。因此，开始于2020年底开始。这项研究的现实影响可能非常重要，从而允许评估不断变化的城市排放制度。
