Ghana’s GAYO takes centre stage with a zero-waste model transforming Africa’s climate future
In a triumphant recognition of community-driven solutions to climate challenges, the Green Africa Youth Organization (GAYO) from Ghana was awarded the prestigious Earthshot Prize in the category of “Clean Our Air” in November 2024. The youth-led, gender-balanced organisation, received the award for its innovative “Zero Waste Model,” a transformative solution that empowers communities, reduces pollution, and promotes circular waste management practices across Africa.
The award was broadcast live across the continent by MultiChoice, Africa’s official broadcast partner of The Earthshot Prize, showcasing the power of African eco-innovation to millions of viewers and reinforcing the platform’s commitment to sustainable development.
A milestone year for African climate innovation
GAYO’s win was part of a landmark year for African sustainability – the first-ever Earthshot Prize ceremony hosted on the continent, in Cape Town in November 2024. The event brought together changemakers from around the world and celebrated African climate leadership on a global stage.
Since its inception, The Earthshot Prize has recognised ten African organisations as finalists, including ABALOBI from South Africa, Reeddi Capsules from Nigeria, Pole Pole Foundation from the Democratic Republic of Congo, Freetown the Treetown from Sierra Leone, and Kenya’s ROAM, Sanergy and d.light. Three African organisations have gone on to win the Prize: GAYO from Ghana, Kenya’s Keep IT Cool and Mukuru Clean Stoves.
Zero waste for cleaner air and stronger communities
GAYO’s “Zero Waste Model” has set a new standard for waste management in Africa, addressing urban waste challenges and their impact on climate change and air quality. With urban expansion driving a surge in waste, the traditional practices of open burning and landfilling have resulted in dangerous greenhouse gas emissions and particle pollution. GAYO’s approach diverts waste from these harmful practices, aiming to reduce greenhouse gas emissions and particle pollution in Ghana by an impressive 70% by 2030.
“Our work in Ghana demonstrates that sustainable waste management isn’t just a possibility -it’s a necessity,” said GAYO co-founder Desmond Alugnoa. “This recognition fuels our commitment to replicating these models across Africa, proving that local solutions can have global impacts.”
Turning waste into work
GAYO’s model is not only an environmental solution but an economic catalyst. The initiative has created over 70 jobs and supported 5,000 people through composting, waste collection, and the production of charcoal briquettes from organic waste. This approach enables communities to transform what was once viewed as trash into products that generate income, fostering a circular economy that empowers individuals and drives local economic growth.
Working alongside local assemblies, environmental organizations, and municipalities, GAYO’s initiatives extend across Ghana and reach into broader regions of Africa. By implementing zero waste practices and promoting knowledge-sharing on sustainable waste management, GAYO aims to influence a continent-wide shift toward environmentally sustainable urban development.
Building climate awareness among Africa’s future leaders
In addition to its practical impact, GAYO is also taking steps to bridge the knowledge gap around climate intervention strategies.
Through Africa’s first comprehensive short course on Carbon Dioxide Removal (CDR) and Solar Radiation Modification (SRM), GAYO seeks to equip Africa’s youth with knowledge essential to participating in global climate conversations. This program is designed for young professionals, climate advocates, and students with backgrounds in science, ensuring that African voices are central in the global dialogue around climate intervention and solutions.
Ernest Ofori, Project Coordinator at GAYO, emphasized the significance of this educational initiative, noting, “In a world grappling with the escalating climate crisis, this knowledge deficit among Africa’s youth, who are the continent’s future leaders and change-makers, presents both a challenge and an opportunity. Our program aims to democratize knowledge on climate interventions and bridge the gap between the Global North and South, ensuring that African perspectives are not just included, but central to the global climate dialogue.”
A model for Africa’s sustainable future
GAYO’s goal to divert 4,000 tonnes of waste by 2030 is supported by its expanding footprint, including ambitions to grow its workforce to 500. Their model has already diverted 170 tonnes of waste and prevented 3.6 tonnes of CO₂ emissions since 2023.
During the Cape Town ceremony, Prince William called Earthshot winners “the game-changers… building the future we all need.” GAYO’s journey is a powerful reflection of that sentiment – and a signal that Africa’s innovation economy is not only emerging but thriving.
As a broadcast partner and Earthshot Global Alliance member, MultiChoice plays a central role in amplifying these stories, connecting solutions to platforms, and supporting the growth of African innovation ecosystems.
“We aim to amplify the climate change message and inspire sustainable solutions through this partnership,” said Calvo Mawela, MultiChoice Group CEO.
GAYO’s work embodies many of the ESG values central to MultiChoice’s sustainability strategy – from the circular economy and pollution reduction to youth empowerment and inclusive job creation. The model also aligns with key Sustainable Development Goals supported by MultiChoice, including SDG 13 (Climate Action), SDG 11 (Sustainable Cities), and SDG 8 (Decent Work).
GAYO’s “Zero Waste Model” continues to grow, setting a powerful example of what can be achieved through innovation, community engagement, and an unyielding commitment to a cleaner, more sustainable future for all.
