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.

Cities driving diesel out of the European car market

European governments have strong incentives to discourage diesel technology and national governments could face fines for failing to meet ambient air quality standards for NOx. As a result, several cities are moving fast to phase out diesel cars, which account for 80% of all NOx emissions from vehicles in Europe.

Shell game? Debating real-world fuel consumption trends for heavy-duty vehicles in Europe

The EU is about to propose new standards to limit CO2 emissions from heavy-duty vehicles. Some manufacturers are still trying to persuade policy makers that regs aren't necessary because truck fuel-efficiency really is improving significantly on its own. Don't be fooled; on average, it isn't.
