This metric is based on the Global Reporting Initiative (GRI) G4 Guidelines. It covers one of the requirements of Indicator G4-EN25 - 'Weight of transported, imported, exported, or treated waste deemed hazardous under the terms of the Basel Convention (2) Annex I, II, III, and VIII, and percentage of transported waste shipped internationally'.

​Hazardous waste management is a key area of concern for many stakeholders. Improper transport of dangerous wastes, particularly to countries that lack the infrastructure and national regulations to handle such waste, can pose harm to both human health and the environment. In addition, poor management of hazardous waste creates liabilities associated with non-compliance with national and international regulations, as well as potential damage to reputation.


To calculate the percentage of hazardous waste shipped internationally -G4-EN25-b:

  • Identify the total weight of hazardous waste transported across international borders.
  • Calculate the percentage, using the total hazardous waste handles (see G4-EN25-a) as the 100% base line.
