The World Meteorological Organization (WMO) reports that greenhouse gas concentrations in the atmosphere have hit new highs: CO2 is at 379.1 parts per million (ppm), up 0.53% from 377.1 ppm in 2004; N2O is at 319.2 parts per billion (ppb); and CH4 is a 1,783 ppb. These values are higher than those in pre-industrial times by 35.4%, 18.2% and 154.7%, respectively. After water vapor, carbon dioxide (CO2, methane (CH4) and nitrous oxide (N2O) are respectively the three most prevalent greenhouse gases in the Earth’s atmosphere. The NOAA Annual Greenhouse Gas Index (AGGI) now shows that from 1990 to 2005 the atmospheric radiative forcing by all long-lived greenhouse gases has increased by 21.5%. The AGGI increased by 1.25% from 2004 to 2005.(More...)

The secretariat of the United Nations Framework Convention on Climate Change (UNFCCC) released new data showing an upward trend in greenhouse gas emissions of industrialized countries (Annex I parties to the UNFCCC) in the period 2000–2004. In particular, transport remains a sector where emission reductions are urgently required but seem to be especially difficult to achieve. Emissions from transportation grew by 23.9% from 1990 to 2004. (More...)

HM Treasury (UK) today published the much-anticipated Stern Review Report on the Economics of Climate Change, the most comprehensive review yet carried out on the economics of climate change. The Review estimates that while the cost of stabilization could be 1% of global GDP by 2050, the longer-term costs of a narrow range of effects of unabated climate change would be at least 5% of global GDP. Considering more recent scientific evidence (for example, the risk that greenhouse gases will be released naturally as the permafrost melts), the economic effects on human life and the environment, and approaches to modeling that ensure the impacts that affect poor people are weighted appropriately, the Review estimates that the dangers could be equivalent to 20% of global GDP or more. (More...)

All Member States must seriously tackle greenhouse gas emissions immediately, if the EU-15 is to meet its collective Kyoto target, according to a new report from the European Environment Agency (EEA). (More...)

According to a recent MIT survey, Americans now rank climate change as the country’s most pressing environmental problem—a substantive shift from three years ago, when they ranked climate change sixth out of 10 environmental concerns. The environment continues to rank in the middle of the list of “most important issues facing the US today.? Among 10 environmental problems, almost half the respondents put global warming in first or second place. In 2003, the destruction of ecosystems, water pollution and toxic waste were far higher priorities. (More...)

Sales of hybrids in the US in October rose to 18,784 units, up 10.9% from the 16,934 sold in October 2005. Total light duty vehicle sales in October in the US increased 6.1% from the year prior, with sales of light trucks up 14.8% and sales of passenger cars down 2.9% year-on-year.

In October, hybrids represented 1.54% of the new car market—an increase from the 1.48% share in October 2005, but a decrease from the 1.72% share in September 2006. (More...)

Lower gasoline prices fueled a boom in sales of pickup trucks and SUVs. GM's retail truck sales jumped up 52% year-on-year, led by a doubling of full-size pickup retail sales such as Chevy Silverado and GMC Sierra and a 46% increase in luxury utility retail sales, including the entire Cadillac Escalade lineup.

Sales of the Chevrolet Tahoe full-size SUV more than doubled to 12,181 units in October while sales of its GMC cousin the Yukon also more than doubled to 10,311 units. Combined, the Yukon and Tahoe SUVs alone represented 22,492 units in October, or 1.8% of the market.

Researchers at the University of Illinois at Urbana-Champaign and Virginia Commonwealth University have concluded that the weight gain of Americans since 1960 has resulted in increased fuel consumption. In a paper to appear in the The Engineering Economist, the scientists conclude that each extra pound of body weight in all of today’s vehicles results in an increase in gasoline consumption of more than 39 million gallons each year. As a result, Americans are now pumping an extra 938 million gallons of fuel as a result of the extra weight in vehicles. (More...)


Toyota Motor may extend the Prius into a line of vehicles as the company tries to triple annual US sales of hybrids. (More...)

The Mayor of London, Ken Livingstone, today unveiled the first hybrid double-deck bus in the world and announced plans for a hybrid bus fleet for London. Built by Wrightbus, the double-decker is a series hybrid with a 660-volt lithium-ion battery pack powering two 85kW electric motors. A 1.9-liter Euro-4 diesel engine is the genset. By contrast, a conventional double-deck bus uses a 7-liter engine. The hybrid bus is expected to cut emissions by up to 40%. (More...)

The Enova hybrid drive systems provided for IC Corporation’s new line of hybrid commercial buses will be available with either a charge-depleting (i.e., plug-in hybrid) or charge-sustaining battery technology. The technologies are expected to improve fuel economy up to 100%. (More...)

UOP LLC, a Honeywell company, has established a new business unit dedicated to introducing new technology for processing renewable energy sources in existing or new petroleum refineries worldwide. The Renewable Energy and Chemicals unit will, among other products, focus on the commercial deployment in 2007 of a second-generation synthetic renewable diesel process that uses vegetable oils, greases and certain waste products as feedstock. (More...)

Virent Energy Systems has been awarded a $2-million dollar grant from the US Departments of Agriculture and Energy to develop further its capabilities to convert glycerol, a co-product of biodiesel production, into renewable propylene glycol, a high-value chemical usually made from fossil fuels. Virent is the developer of an aqueous phase reforming (APR) process for the conversion of readily available biomass-generated feedstocks, such as glucose, sucrose, sorbitol and glycerol to carbon neutral hydrogen, fuel gas or value-added chemicals. (More...)
