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.

A sneak preview of future stages of Indian emission standards for non-road engines reveals a tractor-sized loophole

In short, it’s welcome news that Indian regulators have set their sights on catching up with best-practice emissions standards for non-road engines. Here’s hoping that in aiming for that goal in 2025 they don’t overlook a simple fix that will bring even more immediate help in solving the persistent air pollution problems facing the country.

Quibbles over the perfect way to measure black carbon emissions from ships are keeping us from commonsense moves to control them

Without regulation, it’s unlikely that the international maritime shipping sector will voluntarily find ways to cut black carbon emissions, despite the climate benefit. Thus, we need to move on from quibbling about the “perfect” measurement method and start debating the opportunities to cut black carbon control emissions. But we must move quickly. Because the Arctic we’re aiming to protect can’t keep its cool much longer.
