Speaking on behalf of the family, Green said Kalua had lived with asthma for years and had managed the condition well.
He said there was no indication the day would end in tragedy.
“He was asthmatic. And it was a situation that was very well managed all through. And as he was going on his business, he had an attack,” Green said while appealing for prayers from Kenyans during the difficult period.
His death comes as the Nairobi Rivers Commission continues efforts to restore and protect rivers and riparian areas within the capital.
Kioli had been among professionals supporting initiatives to address pollution, environmental degradation and other challenges affecting Nairobi’s waterways.
Why Kalua’s Death Matters
Beyond his role at the Nairobi Rivers Commission, Kalua was widely known in environmental and climate circles.
He served as the executive director of the Green Africa Foundation and also chaired the Kenya Climate Change Working Group.
In those roles, he played a key part in environmental advocacy and climate policy discussions in Kenya.
Kioli played a central role in drafting, advocating for, and implementing major environmental laws and climate action programs in Kenya.
As a member of the National Climate Change Council, he contributed to the development of the Climate Change Act of 2016, Kenya’s flagship climate legislation, as well as multiple National Climate Change Action Plans that guide the country’s response to global warming and environmental degradation.

His influence extended to county governments, where he helped shape laws including the Kitui County Charcoal Management Act, the Kajiado Climate Change Act, and the Narok County Environment Act, alongside more than 10 other policy and legislative frameworks.
Kioli was also one of the most prominent voices in Kenya’s climate civil society movement.
As chairman of the Kenya Climate Change Working Group (KCCWG) since 2009, he brought together environmental organizations, development partners and government agencies to push for stronger climate policies, increased accountability and greater investment in renewable energy and climate resilience.
Under his leadership, the network became a key stakeholder in national climate discussions.
Beyond Kenya, Kioli was actively involved in international climate diplomacy and represented Kenyan civil society in global climate negotiations under the United Nations Framework Convention on Climate Change (UNFCCC).
He participated in major climate conferences including COP22 in Marrakech and COP26 in Glasgow, where he engaged in discussions on climate finance, renewable energy, methane reduction, adaptation, and climate justice.
His impact also extended to research and knowledge generation. He authored publications such as “A Review of Energy Access in Kenya” and “Impacts of Climate Change on Energy Security,” and produced training materials used by climate and energy practitioners.
