Safaricom tapped KSh20 billion via its inaugural green notes programme, issued under a KSh40 billion medium‑term note framework, after exercising a KSh5 billion greenshoe option.

The proceeds are dedicated to renewable‑energy projects, energy‑efficiency upgrades and power‑management initiatives across the network.

By the end of the financial year ending March 2026, Safaricom had installed solar systems at 2,028 sites, up from 1,432 the previous year, representing 35.7 % of its network locations.

An additional 596 sites were converted to solar power during FY2026, and the operator now targets 3,000 solar‑powered sites by March 2027 and 5,000 by 2030.

Fuel consumption fell to 10.08 million litres of diesel in FY2026, costing roughly KSh2.3 billion, a reduction of about 390,000 litres from the prior year.

Despite the solar expansion, combined Scope 1 and Scope 2 emissions rose 9.1 % to 56,354 tonnes CO₂‑e in FY2026, up from 51,638 tonnes the year before.

The 2026 Sustainable Business Report valued the company’s net environmental impact at KSh6.43 billion, up from KSh2.1 billion the previous year, reflecting the economic cost of its emissions and resource use.
