Topics / Clean Air

The world's transportation fleet—passenger cars and light trucks, heavy trucks and buses, motorcycles and scooters and tuk-tuks, farm tractors and construction equipment, ships and planes—is a massive source of outdoor air pollution, especially in urban areas. The effects of long-term exposure to fine particulates, nitrogen oxides, hydrocarbons, carbon monoxide, air toxics and other pollutants contained in vehicle exhaust include lung cancer, heart disease, stroke, asthma, stunted lung growth in children, and other harmful outcomes. And in some cases, as with the black carbon that is a component of particulate emissions, these pollutants also contribute to short-term climate warming.

ICCT's Clean Air Program advises on strategies to address the public health and near-term climate impacts of outdoor air pollution from transportation. We develop technical underpinnings for the design and implementation of emission control policies to mitigate those impacts at the international, national, and city scales. These policies can include national vehicle emission standards, fuel-quality standards to limit the sulfur content of diesel and petrol, compliance and enforcement programs to ensure that standards are met in practice, vehicle scrappage and repair programs, and other types of initiatives, such as establishment of low-emission zones.
