120-city study: 22% reduction in urban traffic emissions in 15 years without quality of life decline is possible

How do you make transport in the world's big cities more climate-friendly without putting too much pressure on people? A model-based study of 120 major cities around the globe now shows how these two major goals can be reconciled. Subject to the condition that the quality of life is not allowed to decline in any of these cities, tailor-made climate policy in transport can reduce greenhouse gas emissions by 22% in 15 years.
