New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

Historical analysis shows strong acceleration of plantation development in recent years: 70% of all industrial plantations have been established since 2000 and only 4% of the current plantation area existed in 1990. That number is in my opinion conservative, and consistent with a slight reduction in the rate of peat conversion.

U Chicago, MIT study suggests ongoing use of fossil fuels absent new carbon taxes

Green Car Congress

A paper by a team from the University of Chicago and MIT suggests that technology-driven cost reductions in fossil fuels will lead to the continued use of fossil fuels—oil, gas, and coal—unless governments pass new taxes on carbon emissions. Their analysis is published in the Journal of Economic Perspectives. F of warming.

Engineered E. coli produce styrene from glucose

Green Car Congress

Engineers at Arizona State University have engineered E. The conversion of endogenously synthesized l-phenylalanine to styrene was achieved by the co-expression of phenylalanine ammonia lyase and trans-cinnamate decarboxylase. Candidate isoenzymes for each step were screened from bacterial, yeast, and plant genetic sources.

Getting More Students to Develop Tech That Benefits Society

Cars That Think

Gerald Estrin led the development of the WEIZAC , the first digital electronic computer made in the Middle East, and he helped found the computer science department at the University of California, Los Angeles. At UCLA, she designed one of the first systems for analog-to-digital conversion of electrical activity from the nervous system.

Updated Life Cycle Analysis of Soybean Production and Products Show Environmental Improvements

Green Car Congress

A key objective was to update life cycle inventory (LCI) databases for soybean production and processing as well as conversion into four key soy-derived feedstocks (methyl soyate, soy lube base stock, soy polyol, and soy resin) used in fuel and industrial products. kg (for the 3.36

Researchers propose evaluating alt fuel efficiency based on energy rather than volume; impact of ethanol on vehicle efficiency and GHGs

Green Car Congress

In a policy analysis in the ACS journal Environmental Science & Technology , researchers from the Universities of Cambridge, Exeter and Oxford argue that, due to the increased emphasis on alternative fuels with drastically differing energy densities, vehicle efficiency should be evaluated based on energy rather than volume.
