德里的空气质量在2024-25年最差,由于天气和排放,Patna排在第二位。 Delhi had worst air quality in 2024–25, with Patna second, due to weather and emissions.

根据CPCB数据,气候趋势2025年的一项研究发现,德里在2024-25年有最高的PM2.5年级和最长的严重空气质量时期,特别是在冬季,而班加罗尔是印度最有弹性的大城市. A 2025 study by Climate Trends, using CPCB data, found Delhi had the highest annual PM2.5 levels and longest severe air quality periods in 2024–25, especially in winter, while Bengaluru was the most resilient major Indian city. 受空气停滞驱使,巴塔在污染严重性中位居第二。 Patna ranked second in pollution severity, driven by stagnant air. 对六个城市的分析显示,低风速和高湿度等天气条件可以使PM2.5增加40%,即使排放量不高,污染也会加剧。 The analysis of six cities showed weather conditions like low wind speeds and high humidity can increase PM2.5 by up to 40%, worsening pollution even without higher emissions. 专家们敦促改革印度的NCAP第三阶段,包括气候调整目标和行动计划,以便更好地应对气候驱动的污染激增。 Experts urge reforms to India’s NCAP Phase-III, including weather-adjusted targets and action plans, to better address climate-driven pollution spikes.
