Safaricom's debut green bond was significantly oversubscribed, attracting Sh41.4 billion against a target of Sh15 billion. The telecommunications firm will take up Sh20 billion, which is the maximum allowed in this first tranche, after exercising a Sh5 billion greenshoe option. Green bonds are an investment tool for financing environmentally friendly projects, such as renewable energy and clean transport. In other sustainability efforts, Ibis Styles Nairobi Westlands has launched The Green Room, a fully solar-powered events space to reduce the hotel's carbon footprint. Additionally, Ampersand Energy has launched Africa's first open battery-swap network for third-party electric motorcycle manufacturers in a bid to accelerate electric transportation.
