Recession to bring biggest annual fall in CO2 emissions in 40 yearsSeptember 22nd, 2009 LONDON - The worldwide recession might have sent the financial markets in a tizzy, but reports indicate that it is also likely to bring the biggest annual fall in the world's carbon dioxide (CO2) emissions in 40 years. According to a report by BBC news, the International Energy Agency (IEA) estimates that global CO2 emissions will fall by more than 2 percent during 2009.
Increasing residential and employment density may reduce vehicle travel, fuel use and CO2September 2nd, 2009 WASHINGTON - A new report has determined that increasing population and employment density in metropolitan areas could reduce vehicle travel, energy use, and CO2 emissions from less than 1 percent up to 11 percent by 2050. The report is a new congressionally mandated report from the National Research Council in the US.
Researchers: Texas-sized garbage patch in Pacific Ocean possibly killing marine lifeAugust 27th, 2009 Researchers: Pacific trash possibly killing fishSAN DIEGO — Researchers say a Texas-sized garbage patch in the Pacific Ocean is possibly killing marine life and birds that are ingesting the trash. Scientists at Scripps Institution of Oceanography on Thursday announced findings from an August expedition to the Great Pacific Garbage Patch, about 1,000 miles west of California.
Reject watermelon juice can be valuable source of biofuelAugust 26th, 2009 WASHINGTON - In a new research, scientists have shown that the juice of reject watermelons can be efficiently fermented into ethanol, which means that watermelon juice can be a valuable source of biofuel. The research was conducted by Wayne Fish and a team of researchers at the USDA-Agricultural Research Service's South Central Agricultural Research Laboratory in Lane, Oklahoma, US.
Scientists boost production of biofuel that could replace gasolineAugust 20th, 2009 WASHINGTON - Engineers at Ohio State University, US, have found a way to double the production of the biofuel butanol, which might someday replace gasoline in automobiles. The process improves on the conventional method for brewing butanol in a bacterial fermentation tank.
Developing biofuels as alternative to imported oil may damage water resourcesJune 16th, 2009 WASHINGTON - Scientists at Rice University have warned that the US must be careful that the new emphasis on developing biofuels as an alternative to imported oil takes into account potential damage to the nation's water resources. "The ongoing, rapid growth in biofuels production could have far-reaching environmental and economic repercussions, and it will likely highlight the interdependence and growing tension between energy and water security," according to a report titled "The Water Footprint of Biofuels: A Drink or Drive Issue?"

1 litre of milk can generate 1 kg of CO2May 29th, 2009 WASHINGTON - In a new research, scientists have determined that each litre of milk produced in New Zealand can generate nearly 1kg of greenhouse gases - about 85 percent of it on-farm. According to a report in NZPA (New Zealand Press Association), each litre of milk produced causes the emission of greenhouse gases equivalent to 940g of carbon dioxide, meaning New Zealand's leading diary Fonterra's 15 billion litres of milk would produce nearly 15 million tonnes of carbon.
Reducing gasoline emissions will benefit human healthMay 29th, 2009 WASHINGTON - A new study has shown that shown that a biofuel eliminating even 10-percent of current gasoline pollutant emissions would have a beneficial impact on human health. While the focus of a shift from gasoline to biofuels has been on global warming, such a shift could also impact human health.
Global carbon emissions to increase 40 percent by 2030May 27th, 2009 WASHINGTON - The level of carbon emissions into the Earth's atmosphere will surge nearly 40 percent by 2030 if the governments can't force more limits on pollutants blamed for global warming, a US report said Wednesday. The Energy Information Administration (EIA) projected that energy consumption will increase 44 percent between 2006 and 2030, mainly because of higher demands from the developing world.
New electrical device can turn CO2 into biofuelApril 27th, 2009 WASHINGTON - Researchers in the US have made a new electrical device that could improve fuel cell technology by turning carbon dioxide (CO2) into methane, a potential biofuel. According to a report in ABC News, the technique won't combat global warming directly, since both CO2 and methane are potent greenhouse gases, but it could help store alternative energies such as wind and solar more efficiently.
Biofuel crops can become invasive pests in tropical areasApril 22nd, 2009 WASHINGTON - In a new research, scientists have concluded that biofuel crops proposed for use in the Hawaiian Islands are two to four times more likely to become invasive pests in Hawaii and other tropical areas when compared to a random sample of other introduced plants. The research was done by scientists with the University of Hawaii Pacific Cooperative Studies Unit, who examined the impact of unregulated planting of biofuel crops for their potential invasiveness and raised concerns about their impacts on Hawaii's environment.
Biofuels could hasten climate changeApril 15th, 2009 WASHINGTON - A new study has found that biofuels can hasten climate change, and it will take more than 75 years for the carbon emissions saved through the use of biofuels to compensate for the carbon lost when biofuel plantations are established on forestlands. If the original habitat was peatland, carbon balance would take more than 600 years.
Rich nations should pay for pollution from exports: ChinaMarch 17th, 2009 WASHINGTON - The world's wealthiest nations should be responsible for China's pollution coming from exports, Chinese officials said amid talks with the US on how to combat global warming. China, the world's largest polluter together with the US, has a plan in place to reduce greenhouse gas emissions blamed for global warming even as its economy grows rapidly, said Li Gao, director of China's department of climate change.
Obama sets stage for pollution limits with new reporting ruleMarch 11th, 2009 WASHINGTON - The US will ask companies to report on their greenhouse-gas emissions that are blamed for global warming, setting the stage for government-imposed limits on climate pollution supported by President Barack Obama and long resisted by his predecessor. The Environmental Protection Agency (EPA) Tuesday said it will ask most major polluting firms to submit annual reports on their emissions levels beginning with 2010.
Marine algae most promising bet for green fuelJanuary 4th, 2009 WASHINGTON - Scientists see marine algae as the most promising bet for a green fuel that would help ease the dependence on fossil fuel and power vehicles of the future. Scripps Institution of Oceanography, University of Californa San Diego (UCSD), scientists along with their counterparts from its division of biological sciences are part of an emerging algal biofuel consortium that includes academic collaborators, CleanTECH, public and private partners.
