Greenhouse Gas Emissions

An artist's impression of California's new high-speed train

When people grumble about how they think the US isn’t as technologically advanced as it should be, they like to bring up bullet trains – Europe and Asia have them, so why doesn’t America? Well, it’s getting one. Work is starting this summer on a high-speed rail line running from San Francisco to Los Angeles, that will carry a passenger train traveling at over 200 mph (322 km/h).  Read More

Researchers at University of Texas at Arlington have developed a novel means of creating m...

Most previous methods of producing methanol from carbon dioxide have involved lots of electricity, high pressures and high temperatures, and used toxic chemicals or rare earth elements like cadmium or tellurium. A team of researchers at the University of Texas at Arlington (UTA) has developed a new method they claim is safer, less expensive, and simpler than current approaches and can be scaled up to an industrial scale to allow some of the CO2 emitted from electrical power plants to be captured and converted into a useful fuel.  Read More

Graduate student Zachary Baer works with a fermentation chamber to separate acetone and bu...

Researchers at the Energy Biosciences Institute (EBI) are generating bio fuels from renewable sources, such as sugar and starch, using a process that could be commercialized in as little as five to ten years. Although the fuels are currently more expensive to produce than those made from petroleum, they contain more energy per gallon than ethanol and the researchers say that, if adopted, could help to cut greenhouse gas emissions from transportation.  Read More

Hestia is a software system that shows building-by-building CO2 emissions

As the old adage goes, knowledge is power. Following this principle, Arizona State University researchers have developed a computer program called Hestia, that is capable of estimating the greenhouse gas emissions of specific roads and even buildings. With its high level level of detail and accuracy, the software can help cities make more precise calculations about their GHG footprint as well as more informed decisions related to carbon mitigation efforts.  Read More

A new material called NOTT-300 could help reduce emissions from coal-fired power plants, s...

Researchers at the University of Nottingham have developed another weapon in the ongoing war to reduce the amount of greenhouse gases emitted from fossil fuel-burning power plants. The researchers have created a new porous material called NOTT-300 that they claim is cheaper and more efficient than existing materials at capturing polluting gases, such as carbon dioxide and sulfur dioxide, from flue gas.  Read More

Newly-developed earplug-sized air samplers are said to offer several advantages over tradi...

The monitoring of air quality can be a tricky business. Gases may be blown into the sampling site from another area, they may leak out of an air sample before it can be analyzed, or the sampling container itself may introduce compounds, emitted through off-gassing. If samples are being gathered in remote areas, it can also be difficult getting bulky equipment to and from the sampling site. Now, scientists from Sandia National Laboratories have announced a tiny new type of air sampler, that addresses these and other challenges.  Read More

In the face of potentially catastrophic effects on global food production, some have proposed drastic solutions to counteract climate change such as reflecting sunlight away from the Earth. A new study from the Carnegie Institution for Science examining the effects of sunshade geoengineering has concluded that such an approach would be more likely to improve food security than threaten it.  Read More

Lab-grown meat offers significant environmental benefits over conventional meat farming te...

As a meat lover, it's been hard not to notice the rise in the price of meat at my local supermarket over the last few years. But it’s not just the cost to consumers that is a major concern; it’s the major role that livestock production plays on climate change. While cultured meat, also known as in vitro meat, lab-grown meat and even Frankenmeat, might not sound that appetizing to many meat lovers, a new study carried out by scientists from Oxford University and the University of Amsterdam says that cultured meat would provide substantial environmental benefits.  Read More

Sauter Carbon Offset Design's Ark Angel LSV

Like its Super Nova and Ocean Empire LSV stablemates, the 78 meter (256 ft) Ark Angel LSV (Life Support Vessel) from Sauter Carbon Offset Design harnesses energy from a variety of renewable sources to achieve up to 100 percent reduction in fuel consumption and greenhouse gas emissions. When using its four 400 kW Daimler Bluetec Turbo Compound DD16 diesel engines, Sauter says that the green megayacht is capable of sailing at 28 knots while still reducing fuel consumption and emissions by 50 percent.  Read More

Tesla has announced a battery recycling program for Europe

When weighing up the impact of electric-vehicles on the environment two factors come to the fore. EV's produce no emissions locally, but depending on where the energy comes from, they can still be producing greenhouse gases back at the power plant ... the so called "long-tailpipe" argument. That's one. The second is batteries – or more specifically, how much energy goes into making them and what to do with the massive battery packs in these cars once they've passed their lifespan. Auto manufacturers building EV infrastructure are taking this second factor into consideration and now EV pioneer Tesla has announced a battery recycling program throughout Europe that will help reduce the carbon footprint of its vehicles.  Read More
