Motor vehicle emissions harm public health and the environment. The ICCT estimates that exposure to vehicle emissions in the year 2005 produced at least 242,000 global early deaths. Emissions of fine particulate matter, ozone-precursors, air toxics and other harmful pollutants also produce environmental damage in the form of crop fertility losses and near-term climate warming.

Designing from scratch: Maximizing aircraft fuel efficiency
Why aren’t we seeing more radically fuel-efficient aircraft, the way we're seeing more efficient cars and trucks? You can get a lot of different answers to that question, depending on who you ask. The result is a series of interviews, which we'll be publishing here over the next few weeks.

Vehicle and fuel standards can dramatically reduce air pollution in Brazil, São Paulo’s air quality data demonstrate
Implementing P-8 (Euro VI-equivalent) standards for trucks and buses might be the most cost-effective way to improve air quality, not just in São Paulo but nationwide. The benefits associated with P-8 standards outweigh their costs by a ratio of 11 to 1.

Subsidy fraud leads to reforms for China’s EV market
Policy adjustments, created largely in response to the high-profile subsidy fraud scandal, mark major reforms for China’s EV market. As an old Chinese saying goes, “A loss may turn out to be a gain.” After being struck by this scandal, China’s EV market may find the right path toward a prosperous future.
