• Since taking office, Mosiria has shown quality leadership skills and dedication to environmental conservation, sustainable waste management, and innovative green initiatives, which have significantly transformed Nairobi’s environmental landscape.

On April 4, 2025, Chief Officer of Environment in Nairobi Geoffrey Mosiria and his team shut down an illegal dumping site along Bins Road in Mukuru Kwa Ruben, which had been unlawfully set up beside the road.

During the operation, the team seized several lorries that had been dumping waste at the site and took them to the county yard to serve as evidence when their owners are arraigned in court.

“We shall continue to close down all illegal dumping sites in the city. For us to end illegal dumping in Nairobi, we have to start from the source where the garbage is coming from, the people involved in the illegal dumping, because these are the biggest polluters that we have in the city,” he said.
