Road freight emissions worldwide as of 2020, by vehicle type
Approximately 1.2 billion metric tons of carbon dioxide is produced worldwide by 27 million heavy-duty trucks (HDTs). This accounts for 41 percent of global road freight emissions. In comparison, the fleet of 144 million Light Commercial Vehicles (LCVs) produced roughly half the emissions of HDTs. The global road freight sector is responsible for nine percent of global greenhouse gas emissions.
