Main Takeaways

• Internal combustion vehicles – those that run on gasoline and diesel fuel – produce CO₂ and a number of air pollutants.
• Over recent decades, big improvements have been made in reducing vehicle-emission pollution; however, it is still problematic at a global scale.
• Transport accounts for one fifth of CO₂ emissions globally; of this portion the majority comes from road transport (cars, motorcycles, buses, and taxis).
• Rising atmospheric CO₂ from vehicle emissions and other human activities has been driving recent global warming.
• Air pollution from vehicles has health effects like respiratory and cardiovascular diseases, and even an increased risk of getting cancer.
• You can reduce your vehicle pollution by using more sustainable transport options like electric vehicles, ride sharing, walking, bicycles, and public transport.
