Walk any commercial district of Nairobi today and the change announces itself in steel and glass: certified green towers, rainwater infrastructure, solar pre-wiring as standard. The driver is not aesthetics but finance. Lenders tied to international capital increasingly price environmental performance into project debt, and tenants, particularly global firms, are unwilling to sign ten-year leases in buildings that will age badly on disclosure regimes.
Policy is following the capital. Green building codes are moving from voluntary frameworks to approvals requirements in several African cities, and the developers who treated ESG as compliance paperwork are discovering that the market has repriced their assets. The rebar, as one contractor told us, no longer lies.
