South Africa launches its first vehicle emissions study in Johannesburg
The project aims to gather accurate emissions data from vehicles in Johannesburg and the broader Gauteng region. The initiative is part of The Real Urban Emissions (True) Initiative, in partnership with Breathe Cities, and will support evidence-based policies such as clean air zones and stricter emission standards.
Vehicle pollution accounts for more than 75% of nitrogen dioxide emissions in Johannesburg, making it a large contributor to poor air quality. Until now, the city has lacked detailed emissions data on which to base interventions.
Using roadside remote sensing technology, the project will measure tailpipe emissions from more than 100,000 vehicles of various sizes and fuel types. Unlike previous African True campaigns that used mobile 'plume-chasing' methods, this study will use stationary equipment placed along Johannesburg roads.
To kick off the campaign, UJ Peets hosted a training workshop with Opus remote sensing for city officials and local partners, followed by a live demonstration of the technology.
'The True Initiative gives us the real-world data we need to shape impactful policy and deliver cleaner streets,' said Musa Mahlatji, deputy director: air quality management.
UJ Peets project leader Boitemogelo Kwakwa added: 'We're turning data into action and building local expertise in emissions monitoring.'

South Africa launches its first vehicle emissions study in Johannesburg
The City of Johannesburg's environment and infrastructure services department, through its climate change and air quality unit, in collaboration with the University of Johannesburg's process, energy and environment technology station (UJ Peets) and the International Council on Clean Transportation, has launched South Africa's first roadside remote sensing study to assess real-world vehicle emissions.

The Soweto geologist uncovering the Earth's secrets
Tebogo Makhubela, a South African geologist recipient of one of the prestigious National Geographic 2025 Wayfinder Awards, dims the head lamp fixed on his safety helmet as he poses for a portrait inside the The Rising Star cave, in The Cradle of Humankind. In the 1997 action film "Dante's Peak", Pierce Brosnan plays the role of a volcanologist sent to investigate seismic activity beneath a long-dormant volcano. Years after its release, the story inspired South African Tebogo Makhubela to become a geologist, the 35-year-old said. Winner of one of the prestigious National Geographic 2025 Wayfinder awards, Makhubela leads a research team working to uncover ancient clues to human evolution. His turf lies below the surface of the Earth in the limestone caves of South Africa's Cradle of Humankind, a UNESCO World Heritage site about 50 kilometres northwest of Johannesburg. Speaking from inside The Rising Star cave, one of the numerous caves in the area, Makhubela said he and his colleagues have only "scratched the surface" of the site, which dates back five million years. In an unassuming savannah field, hidden under a rocky patch of grass, the cave is where scientists in 2013 discovered Homo naledi, an ancient human relative that lived about 300 000 years ago. "With this cave we've only studied 30 percent... To do the remaining 70 percent we need 20 years minimum," said Makhubela, wearing a dark green overall and a helmet fixed with a torchlight. And with many other caves to study, Makhubela's research isn't close to an end. "I will actually retire before we finish. Hence, I need to train a lot of students to take over from me." Makhubela, who lectures at the University of Johannesburg and supervises four PhD students, hopes more young scientists will join him on his mission -- one he believes is crucial to understanding the history of humankind and its environment. "Geology helps us understand Earth, our planet, how it works, how it was formed, its composition and its processes," he said, sitting on a rock next to his yellow backpack filled with notebooks, pens, measuring instruments and water. His own speciality is geochemistry and geochronology, or more simply, determining the age of fossils and environmental changes over time. One hurdle, he said, is that geology is not well known and some young people would rather "chase what is popular". "Right now we're living in the age of artificial intelligence. (But) you don't have to run and go study computer science or IT because you want to be relevant to the times," said the geologist. "If you're more passionate about natural science, go for it. Because if you do it well, there will be a place for you." Born and raised in Soweto, the sprawling township once home to Nelson Mandela, Makhubela was the first in his family to go to university. His mother never went to school and worked as a street vendor while his father moved away when he was 10, he said. As a bright young student, he was pressured to study engineering and work in South Africa's lucrative gold mining industry. But he decided on another path. "Curiosity inspires me, honestly. I have a lot of questions," he joked, describing what motivates him. And a decade after making that bold decision to forgo a future in mining and pursue his passion in geology, Makhubela is proud of his accomplishments. "I've got a very thriving, fulfilling career, one which is winning me international awards," he said. He's even become a superhero, featuring as a character in a South African comic book and animation series to inspire children about the wonders of science. | AFP

City of Johannesburg takes a stand for clean air
#PauseAndBreathe is more than a one-day activation On Saturday, 28 June, the City of Johannesburg, in collaboration with the pioneering Breathe Cities initiative, hosted the #PauseAndBreathe campaign across the city and with a flagship Hike for the Environment at Kloofendal Nature Reserve in Roodepoort. Even as a cold front gripped Joburg, the sun broke through to warm residents who gathered to pause, breathe and take a collective stand for cleaner air. The Hike for the Environment formed part of Youth Month celebrations and included a guided nature walk, youth-led environmental exhibits and interactive learning experiences. Among the 200 attendees were representatives from Pikitup; student volunteers from the University of Johannesburg; South African Institute of International Affairs air quality youth ambassadors; the Johannesburg Member of the Mayoral Committee (MMC) for Environment; ward councillors; members of the Johannesburg Junior Council; and the Junior MMC for Environment. Attendees showed strong community interest in air quality issues, and the conversation gained momentum online as people shared images and messages using #PauseAndBreathe, #CleanAirJozi and #JoburgCares to amplify the call for immediate action. At 12pm, participants at Kloofendal paused mindfully to show support for clean air for all Joburgers. All music and activity stopped for a brief moment, and breathing coach Marj Murray of Breathwork Africa led a guided breathing exercise. Across the city, residents also joined in, at home with family, at work or outdoors, sharing reflections and photos online. In the lead-up to the day, Johannesburg Executive Mayor Dada Morero said, 'Air pollution is not just a global environmental issue – it's a public health emergency. In Johannesburg, we witness its effects most sharply during the winter months, especially in our most vulnerable communities. As Executive Mayor, I'm committed to mobilising the full resources of the city to take bold, decisive action that will clean our air, protect our health and secure a better quality of life for every resident.' Johannesburg MMC for Environment and Infrastructure Services Jack Sekwaila, who took part in the Kloofendal event, said: 'This day is about accountability – facing the environmental challenges head-on and standing together to come up with solutions that are not only sustainable, but are just, inclusive and empowering. We must work together as residents to phase out harmful practices and adopt cleaner technologies and put people's health first.' Everest mountaineer and expedition leader Sibusiso Vilane supported the campaign and shared on X, 'I fully support the #PauseAndBreathe campaign for #CleanAirJozi. Clean air is essential for all life, everywhere. It is the breath of our existence, foundational to our health, ecological balance and well-being.' The Kloofendal event also served as the official release of a new polling report supported by the City of Johannesburg and Breathe Cities: Defining a Clean Air Zone for Johannesburg. According to the report, 92% of surveyed Joburg residents are concerned about air quality, and 78% of people living with illnesses believe their conditions are linked to the quality of the air they breathe. Johannesburg is one of 14 cities supported by Breathe Cities, a programme delivered by the Clean Air Fund, C40 Cities and Bloomberg Philanthropies to help cities reduce air pollution through data-driven strategies and community collaboration. As part of Breathe Cities, the city has reaffirmed its commitment to implementing air quality solutions and continuing public engagement. #PauseAndBreathe is more than a one-day activation. It marks the start of an ongoing programme of activities and awareness campaigns by the City of Johannesburg to improve air quality and involve residents in long-term change. Three key initiatives are already underway: A new study will identify the main sources of air pollution and highlight which areas of Johannesburg are most exposed. This will help the city design smarter, more focused interventions. South Africa's first real-world vehicle emissions testing campaign begins in July. Focusing on the transport sector, it will assess Joburg's vehicle fleet and identify the types of vehicles and areas responsible for the highest emissions. The findings will inform future policy to reduce transport-related pollution. A health risk assessment will quantify the impact of air pollution on residents. It will provide clearer links between air quality and public health and support stronger actions to protect communities. Residents can learn more about clean air initiatives and how to get involved by following the city's social media pages and official website.
