Study finds that worldwide SO2 emissions rose between 2000-2005 after decade of decline; China, shipping topped growth

Green Car Congress

Global sulfur dioxide (SO 2 ) emissions peaked in the early 1970s and decreased until 2000, with an increase in recent years due to increased emissions in China, international shipping, and developing countries in general, according to a new analysis appearing in the open access journal Atmospheric Chemistry and Physics.

Study concludes abundant shale gas is neither climate hero nor villain; need for targeted GHG reduction policy

Green Car Congress

While natural gas can reduce greenhouse emissions when it is substituted for higher-emission energy sources, abundant shale gas is not likely to substantially alter total emissions without policies targeted at greenhouse gas reduction, according to a new study by two researchers at Duke University. —Newell and Raimi.

Researchers Propose Solar-Driven Biomass Gasification Pathway for Synthetic Fuel Production

Green Car Congress

Researchers at the Norwegian University of Science and Technology (NTNU) are proposing a new process for producing synfuel from biomass using concentrating solar energy as its main energy source. The researchers modeled the production of methanol, which can be used directly as transport fuel or as input for DME and FT-diesel synthesis.

China’s New Breeder Reactors May Produce More Than Just Watts

Cars That Think

China is in the middle of a big buildup of its nuclear-weapon arsenal,” says Frank von Hippel , a physicist and nuclear-policy expert at Princeton University. “My The first step was a 20-MW experimental fast breeder reactor near Beijing, which was begun in 2000 but took many years to complete and connect to the grid.

IEA: improving efficiency of road-freight transport critical to reduce oil-demand growth; three areas of focus

Green Car Congress

Yet the growth in oil demand from trucks has outpaced all other sectors—including passenger cars, aviation, industry and petrochemical feedstocks—since 2000 and contributed 40% to global oil demand growth, a similar contribution as cars.
