The International Day of Climate Action, observed annually on 24 October, reminds us of the global urgency to address the climate crisis and safeguard the planet for future generations. The 2025 theme, ‘Climate solutions through science and innovation’ highlights the essential role that research and technology play in advancing sustainability.

The National Science and Technology Forum (NSTF) joined the global community in commemorating this day by recognising one of South Africa’s award-winning scientists whose work drives sustainable progress. Professor Nobanathi Wendy Maxakato, recipient of the 2025 NSTF-TIA (Technology Innovation Agency) Green Economy Award in the prestigious NSTF-South32 Awards, known as the ‘Science Oscars’ of South Africa, is known for her groundbreaking research in chemistry and green technologies that directly address climate change.
On the occasion, Professor Maxakato said:
“Climate change is one of the most urgent challenges of our time. Through chemistry and sustainable science, we can develop innovative solutions that protect the planet while improving the lives of people in vulnerable communities.”
Prof Maxakato is a Distinguished Professor of Chemistry at the University of Johannesburg (UJ), recognised for her pioneering research in nanomaterials, catalysis, and green chemistry. Her work focuses on developing environmentally friendly catalytic materials for clean energy production, pollution control, and sustainable industrial applications.
Her academic journey reflects a steadfast commitment to scientific excellence. She earned her BSc and BSc Honours in Chemistry from the University of the Free State, followed by an MSc and PhD in Chemistry from University of the Witwatersrand , where she specialised in advanced materials for environmental and catalytic applications. Her research excellence and leadership have since established her as a prominent figure in sustainable materials science, positioning SA as a contributor to global environmental innovation.
At UJ, Prof Maxakato leads a research group focused on synthesising nanostructured catalysts that promote cleaner energy technologies and reduce industrial waste. Her projects contribute directly to the United Nations (UN) Sustainable Development Goals, particularly SDG 7: Affordable and Clean Energy and SDG 13: Climate Action.
Prof Maxakato’s contributions to science have earned her multiple accolades. This year she received the NSTF-TIA Green Economy Award, recognising her outstanding leadership in developing scientific research capacity and mentoring the next generation of chemists, especially women, in STEM fields (science, technology, engineering and mathematics.)
“I am truly humbled and honoured for this recognition. It reminds me that all the late nights, experiments and challenges experienced were worth it. I have always been passionate about science and technology because I was curious to know what happens when you mix the solutions in the lab, and I wanted to make new discoveries. This recognition shows me that curiosity and hard work do pay off. This will motivate me and my research team to work even harder,” Maxakato said.
Her scholarly impact includes numerous peer-reviewed publications, international conference presentations, and collaborative research projects with global scientists focused on renewable energy and environmental remediation. Her mentorship has empowered emerging researchers to pursue studies that address both national and global sustainability goals.
Climate action and the role of science
The Intergovernmental Panel on Climate Change (IPCC) makes clear that limiting global warming to 1.5°C requires unprecedented changes across all sectors. Science and technology are central to this transformation. Through research into clean energy systems, carbon capture technologies, and eco-friendly materials, scientists like Prof Maxakato are helping to build the foundation for a resilient and sustainable future.
Observing the International Day of Climate Action, the NSTF celebrated Prof Maxakato, a scientist whose work embodies innovation, sustainability and hope. Her pioneering research continues to influence climate-focused scientific advances and inspire a generation dedicated to safeguarding the Earth through knowledge and action.
The NSTF remains committed to promoting collaboration between researchers, policymakers, and industry to advance climate solutions that address both environmental and social needs.
