孟买是2021年印度主要城市中公路交通每公里CO2排放量最高的城市,每公里5-6吨。 Mumbai had the highest road traffic CO₂ emissions per kilometer among major Indian cities in 2021, at 5–6 tonnes per km.

根据《科学数据》公布的一项研究,孟买是2021年印度主要城市中公路交通每公里CO2排放量最高的城市。 Mumbai had the highest road traffic CO₂ emissions per kilometer among India’s major cities in 2021, according to a study published in Scientific Data. 这项研究是CHETNA项目的一部分,发现车辆高密度导致排放量达到每公里5-6吨二氧化碳,超过了德里、孟加拉、钦奈、浦那和海得拉巴。 The research, part of the CHETNA project, found that high vehicle density drove emissions to 5–6 tonnes of CO₂ per km, surpassing Delhi, Bengaluru, Chennai, Pune, and Hyderabad. 所有城市的氮氧化物和一氧化碳含量均呈上升趋势,较大型的计量器排放量更高。 All cities showed elevated nitrogen oxides and carbon monoxide levels, with larger metros emitting more. 城市人均CO2排放量每年保持在0.2吨以下。 Per capita CO₂ emissions remained under 0.2 tonnes annually across cities. 该研究使用了500米分辨率数据,并将为未来的城市仪表板提供信息,并计划于2026年2月在孟买举办一次利益攸关方讲习班。 The study used 500-meter resolution data and will inform future city dashboards, with a stakeholder workshop planned in Mumbai in February 2026.
