In December 2018, the Municipal Solid Waste Initiative promoted a workshop hosted by the city of Nairobi, Kenya, to mark the launch of the Sub-Sahara & East Africa City Network. The workshop was a manifestation of the renewed partnership between C40 and CCAC, where 14 cities from both the C40 Sustainable Waste Systems Network and the newly launched CCAC Municipal Solid Waste Initiative Sub-Sahara & East Africa City Network participated.It represented a rare opportunity to bring together city experts from core areas of the global South, to develop in-depth insight and experience sharing on solid waste management topics that are of common interest among participating cities.Stronger relations were established between these cities and a strong momentum was built to work together on key topics that will support the overarching objective of achieving universal collection and safe disposal of municipal solid waste, reducing greenhouse gas emissions linked to this sector.
