Quick and simplified example to illustrate the difference: US car getting 33.5mpg (7.0 l/100km) emitting 126g of CO2 per kilometer. That’s 18g of CO2 per liter of fuel. EU car getting 39.2mpg (6.0 l/100km) emitting 120g of CO2 per kilometer. That’s 20g of CO2 per liter of fuel. It’s been years since I read about this, so I can’t remember the details of how/what it’s measured.
