ONE LEAF+ factsheet:

  • ONE LEAF+ stands for Low Emission-Able Freight. The “+” symbolises the advancement that ONE anticipates from decarbonizing the supply chain.
  • To calculate our customer’s existing emissions, ONE employs the industry-standard Clean Cargo Working Group methodology managed by Smart Freight Centre.
  •  ONE’s biofuel selection criteria is to use only regulation-compliant fuels.
