Offset travel between Chicago and Tampa Bay for as little as a latte Partners with Conservation International, Sustainable Travel International to support reforestation and renewable energy projects CHICAGO, April 22 /PRNewswire-FirstCall/ -- United Airlines today launched a carbon offset program designed to give customers the opportunity to help protect the environment by supporting renewable energy and reforestation projects. This program complements United's existing efforts to...

Singapore scientists announced they have discovered a way to convert carbon dioxide into clean-burning methanol through a procedure that takes less energy than earlier efforts.The Institute of Bioengineering and Nanotechnology scientists made known Thursday they took non-toxic organocatalysts to formulate ethanol, a biofuel used as industrial feedstock.Released in a statement, the institute said the team, headed by Yugen Zhang, utilized N-heterocyclic carbenes, or NHCs, an organocatalyst in...

Emissions of greenhouse gases in the United States rose 1.4 percent in 2007 compared with 2006, according to a report released Wednesday by the U.S. Environmental Protection Agency (EPA).Total emissions of six main greenhouse gases in 2007 were equivalent to 7,150 million metric tons of carbon dioxide, the report said. These gases include methane, carbon dioxide, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride.According to the report, U.S. emissions of these gases...

Increasing levels of carbon dioxide in the atmosphere are a concern to many environmentalists who research global warming.The lack of atmospheric carbon dioxide (CO2) concentration, however, actually limits the growth of plants and their aquatic relatives, microalgae.For plants and microalgae, CO2 is vital to growth. It fuels their photosynthesis process that, along with sunlight, manufactures sugars required for growth.CO2 is present in such a limiting concentration that microalgae and some...

U.N. delegates discussed on Tuesday targeting several new industrial chemicals for inclusion in a climate treaty to succeed the 1997 Kyoto Protocol, which expires in 2012.  Scientists caution that these new synthetic compounds are powerful greenhouse gases that in large quantities could contribute substantially to global warming.  "In terms of the impact these new gases will have over the next decade, it is not that significant," said Steve Sawyer, executive director of the...

A tiny microbe can take electricity and directly convert carbon dioxide and water to methane, producing a portable energy source with a potentially neutral carbon footprint, according to a team of Penn State engineers."We were studying making hydrogen in microbial electrolysis cells and we kept getting all this methane," said Bruce E. Logan, Kappe Professor of Environmental Engineering, Penn State. "We may now understand why."Methanogenic microorganisms do produce methane...

SILVER SPRING, Md. and NEW YORK, March 30 /PRNewswire-USNewswire/ -- Carbonfund.org's Tensas National Wildlife Refuge Reforestation Project in Louisiana has become the first reforestation carbon offset project in North America to achieve dual validation by the Rainforest Alliance to the Voluntary Carbon Standard (VCS) as well as the Climate, Community & Biodiversity (CCB) Standards with Gold Distinction. Over 600,000 metric tons of carbon dioxide emissions will be sequestered from the...

The benefits to animals of omega 3 fatty acids in fish oils have been well documented "“ helping the heart and circulatory system, improving meat quality and reducing methane emissions.These last two benefits may only apply to cows but lowering emissions is important for the environment, as methane given off by farm animals is a major contribution to greenhouse gas levels. Today (Monday 30 March) researchers from University College Dublin reported that by including 2% fish oil in the diet...
