Greenhouse Gas Emissions

As part of the push to reduce greenhouse gas emissions produced by burning fossil fuels researchers from the UCLA Henry Samueli School of Engineering and Applied Science have developed a greener way to extract biofuel from bacteria. The team has genetically modified a cyanobacterium to consume carbon dioxide and produce the liquid fuel isobutanol, which holds great potential as a gasoline alternative. As an added bonus that reaction is powered directly by energy from sunlight, through photosynthesis. Read More
“Electric cars should be rewarded for their energy efficiency, not for moving emissions from exhaust pipes to powerstation chimneys” says the UK's Environmental Transport Association (ETA). In a report titled "How to avoid an electric shock - Electric cars: from hype to reality", the ETA has taken a close look at electric-powered vehicles (EVs) and their associated technologies. In what could be a shock to some commuters – and governments - the report states that EVs could potentially speed climate change, rather than reduce it, and might not be as good for the planet as some of the spin suggests. Simply put, it’s not necessarily the cars themselves that will cause the damage, but the way the electricity is generated to power them and how often we drive them. For instance, EVs powered by “green energy” - wind or solar - are obviously superior, but if the electricity comes from coal, hybrids perform better. Read More
California Governor Arnold Schwarzenegger has introduced Vision Industries’ Tyrano semi truck – a hydrogen-powered zero emissions vehicle designed to replace diesel and LNG short haul trucks in California. Vision says the Tyrano is the world’s first “green” heavy duty class 8 truck with zero emissions (zero CO2, zero fossil fuels, zero noise pollution and a zero carbon footprint). What’s more, the company claims the Tyrano is twice as powerful as a conventional diesel-powered vehicle. Read More
Arctic temperatures in the 1990s reached their warmest level of any decade in at least 2,000 years, new research indicates. The study, which incorporates geologic records and computer simulations, provides new evidence that the Arctic would be cooling if not for greenhouse gas emissions that are overpowering natural climate patterns. The international study, led by Northern Arizona University and the National Center for Atmospheric Research (NCAR), will be published in the September 4 edition of Science. Read More
The Riversimple Urban Car, a hydrogen-powered two-seater capable of speeds up to 50mph and of traveling more than 200 miles without refueling, was unveiled in London this week. While the prototype car is itself a welcome development in sustainable travel, the aim of the company behind it is even more ambitious: to completely eliminate the environmental impact of personal transport.

By looking at the environmental impact of passenger transport – whether it be trains, planes or automobiles – beyond the exhaust fumes spewing from its collective tail pipe, researchers in the United States have discovered a significant spike in energy use and greenhouse gas emissions. By taking into account transport support systems – which includes sourcing raw materials, manufacturing, as well as the construction and maintenance of infrastructure – researchers at the University of California hope to provide a more detailed view for transport planners and policy makers. And produce a better outcome for the environment. Read More
Hankook says its new range of low rolling-resistance tires could delivering significant fuel savings and environmental benefits without consumers having to upgrade their car. The silica compound enfren tire achieved a 5.1% saving over conventional steel belt radials in a recent Fuel Economy Challenge using two identical Hyundai i30 SLX CRDi hatches. Read More
We all know we should turn off appliances at the wall to reduce fire risk as well as our carbon emissions, but the truth is most of us can't be bothered or think to flick the switch. The eco-switch could be the answer: it’s a simple and inexpensive energy-saving device that lets you relocate the power point switch to a more convenient spot where you can turn multiple appliances on and off – with the flick of a single switch.
