Geoffrey Mosiria Removed ,Nairobi’s Environment Office

By Samson Mwangi

In 18th November 2025, Geoffrey Mosiria was removed from his position as Nairobi’s Environment Chief Officer during a county leadership reshuffle. The move, announced at City Hall, was made to reorganize county operations after concerns arose about his confrontational enforcement approach.

Geoffrey Mosiria was the Chief Officer for Environment in Nairobi County and, therefore, was at the heart of environmental management and enforcement in the city. He worked day in, day out, to keep Nairobi clean, orderly, and environmentally safe to live in. As the officer charged with enforcing environmental laws, Mosiria conducted random inspections across the city to ensure that businesses, hotels, eateries, and street food vendors dispose of waste correctly. When individuals or establishments violate these regulations, he spearheads crackdowns on them to bring them to book. This included arresting those who throw waste on the wrong side of the law or operate in unhygienic conditions, enabling the improvement of health and cleanliness within the city's spaces.

Apart from waste management, Mosiria also played a major role in addressing noise pollution, one of Nairobi's persistent challenges. He often responds to cases where clubs, events, or businesses create excessively loud noise and disturb nearby communities. Through on-site interventions, he ordered offenders to lower their volume and, in certain cases, stop operations entirely until compliance is attained. His work also involves the protection of public assets like dustbins placed across the Central Business District. Several times, he had personally apprehended individuals caught vandalizing or stealing these facilities, showing how hands-on he is in protecting city infrastructure.

Overall, Geoffrey Mosiria's role from the perspective of an Environment Chief Officer reflected a mix of enforcement, public safety, and city management. His actions focused on making Nairobi cleaner, safer, and better-organized, and he emphasized accountability just as much as the protection of shared public spaces.
