Volkswagen 2.0 TDI diesel for Euro 6d; SCR twin-dosing

Green Car Congress

With SCR twin dosing technology in the exhaust gas system, the diesel unit now undercuts the Euro 6d emission standard limits while also running quietly and smoothly, according to the company. In 2015, the emissions scandal erupted over the use of defeat devices in Volkswagen engines for MY 2009 through 2015.

Researchers use melamine to create effective, low-cost carbon capture; potential tailpipe application

Green Car Congress

The process for synthesizing the melamine material, published in an open-access paper in the journal Science Advances , could potentially be scaled down to capture emissions from vehicle exhaust or other movable sources of carbon dioxide. The energy savings come from not having to heat the substance to high temperatures.

New fuel-efficient bulk carrier concept design; DNV estimates new tankers, bulkers and container vessels will be up to 30% more energy efficient by 2020 than newbuilds today

Green Car Congress

The Green Dolphin concept design is a five-cargo-hold CSR (Common Structural Rules) double-hull bulk carrier that meets current and future expected air and water emissions regulations. Wash water holding tanks are also included. This reduction level will also be mandated within the Emission Control Areas (ECAs) by 2015.
