All variants of the new motor should meet the tough Euro 7 emissions standards

Volvo continues to chase better fuel economy with the development of a new three-cylinder engine, which will sit alongside the Swedish brand's Drive-E four-cylinder motors in its lineup.  Read More

New research suggests that it takes just 10 years for CO2 emissions to have maximum effect...

Any given CO2 emission will have its maximum warming effect just 10 years later, new research from the Carnegie Institution for Science shows. The Institute of Physics (IOP) says this research, published in full on the web today, has "dispelled a common misconception" that the warming effects of CO2 emissions aren't felt for decades.  Read More

A study carried out at MIT suggests that altering the quantities of materials in cement mi...

As one of our most relied upon construction materials, concrete makes a significant contribution to our overall carbon emissions. Calcium-based substances are heated at high temperatures to form the cement, a process that produces carbon dioxide. But by slightly altering the quantities of materials used, scientists from MIT have uncovered a new method of cement mixing that could reduce these emissions by more than half.  Read More

An aluminum piston (left) and one of the new steel pistons (right)

In 1936, Mercedes-Benz became the first company in the world to launch a diesel passenger car – the 260D. Over the years, diesel automobiles became renowned for their efficiency and fuel economy. Now, the manufacturer is building on that success with the introduction of high-tech steel pistons.  Read More

The UCR NOx-Out device replaces the muffler on an existing gas mower

Gas-powered lawnmowers are notorious polluters. According to the US Environmental Protection Agency, running a new gas mower for one hour produces as much air pollution as would be generated by 11 typical automobiles being driven for the same amount of time. Switching to an electric or reel mower is certainly one option, but for those applications where it's gotta be gasoline, a team of engineering students from the University of California, Riverside are developing another: an attachment that they claim reduces noxious emissions by over 90 percent.  Read More

Researchers at Princeton University have converted CO2 into formic acid by using an electr...

Rising atmospheric CO2 levels can generally be tackled in three ways: developing alternative energy sources with lower emissions; carbon capture and storage (CCS); and capturing carbon and repurposing it. Researchers at Princeton University are claiming to have developed a technique that ticks two of these three boxes by using solar power to convert CO2 into formic acid.  Read More

Ford's Lightweight Concept vehicle based on the Fusion weighs less than a Fiesta

At NAIAS in January, Ford showed the world its new lightweight F-150 truck, which slashed 700 lb (318 kg) from its predecessor's weight to improve handling and fuel economy. Now the automaker has taken the weight-saving techniques from the F-150 and applied them to a new Lightweight Concept vehicle based on a Ford Fusion sedan.  Read More

EcoCAR 3 tasks students with updating the iconic Chevrolet Camaro muscle car into a hybrid...

For the past 26 years, the US Department of Energy (DOE), in partnership with the North American auto industry, has sponsored Advanced Vehicle Technology Competitions (AVTCs) to provide the next generation of automotive engineers with a practical learning experience. The previous EcoCAR Challenge saw students convert and massage GM Malibus into super-efficient models, and this time for EcoCAR 3, teams are tasked with updating the iconic Chevrolet Camaro muscle car into a hybrid-electric vehicle.  Read More

New research by Sintef scientists has found that refrigeration technology may reduce cost ...

For years carbon capture and storage (CCS) has been considered a costly but necessary step in reducing emissions and protecting our environment. New research by Scandinavian research organization Sintef has found that refrigeration technology may reduce costs by up to 30 percent, increasing the potential for faster implementation.  Read More

The team observed reductions in emissions of NOx, particulate matter and greenhouse gases ...

The EPA has identified pollution from ships as a contributing factor to respiratory problems and premature deaths suffered by residents of the US and Canada. As such, it is in the process of implementing stricter emissions standards for ships operating within 200 miles (321.9 km) of shore with the aim of significantly reducing emissions by the year 2020. In a development that could play into these environmental initiatives, the SeaChange Group, a US-based start-up that converts agricultural by-products into clean-burning fuel, has been awarded a patent for an eco-hybrid fuel technology shown to reduce NOx, particulate matter and greenhouse gas emissions.  Read More
