DHL Aviation, the in-house airline of DHL Express, is launching a new optional GoGreen Plus service for its air cargo product. From June, it will allow customers to reduce (‘inset’) the carbon emissions associated with their cargo using sustainable aviation fuel (SAF). They can also tailor the CO2 reduction they want to achieve and the amount of SAF they use. SAF is produced from waste oils and can provide greenhouse gas emission reductions of up to 80% over its lifecycle compared with the conventional jet fuel it replaces.
