Emissions from the transportation sector are notably high in Johannesburg. As part of this transport network project, we examined emissions from Lanseria International Airport, specifically analyzing VOC levels and criteria pollutants on the tarmac, along the runway, at refueling points, and inside buildings. Subsequently, mitigation strategies were implemented based on findings, resulting in reduced emission levels during subsequent assessment campaigns.

Their ongoing plans involve extending this study to assess emissions from other modes of transportation, such as metrobus services, taxi rank associations, and minibus services. Additionally, we aim to assess the air quality in schools and its potential health impact on students.

Country Profile (South Africa): Opportunity Score 7.4 (Medium): Annual average PM2.5 levels are more than 4 times the WHO guideline. There is no public PM2.5 data produced by the government, but there is a national ambient air quality standard for PM2.5.
