Helios Towers reports assured Scope 1 and 2 emissions and a Scope 3 inventory that includes purchased goods, but its total emissions rose from 517,025 to 548,576 tCO2e in 2025, and diesel generators remain its largest energy source. Its only target is intensity-based and self-set, and the company says it would allow absolute emissions to rise by about 22% on 2020.
