Long‐term exposure to elevated CO2 and O3 alters aspen foliar chemistry across developmental stages.

05-09-2013 | JJ COUTURE, LM HOLESKI, RL LINDROTH, Plant, Cell & Environment, 2013

Abstract Anthropogenic activities are altering levels of greenhouse gases to the extent that multiple and diverse ecosystem processes are being affected. Two gases that substantially influence forest health are atmospheric carbon dioxide (CO2) and tropospheric ozone (O3). Plant chemistry will ...

Joint CO2 and CH4 accountability for global warming [Sustainability Science]

30-07-2013 | Kirk R. Smith; Manish A. Desai; Jamesine V. Rogers; Richard A. Houghton, Proceedings of the National Academy of Sciences current issue, 2013

We propose a transparent climate debt index incorporating both methane (CH4) and carbon dioxide (CO2) emissions. We develop national historic emissions databases for both greenhouse gases to 2005, justifying 1950 as the starting point for global perspectives. We include CO2 emissions from fossil ...

Energies, Vol. 6, Pages 1250-1265: Development of Specific Rules for the Application of Life Cycle Assessment to Carbon Capture and Storage

04-03-2013 | Strazza, Carlo ; Del Borghi, Adriana ; Gallo, Michela, Energies, 2013

Carbon Capture and Storage (CCS) is a very innovative and promising solution for greenhouse gases (GHG) reduction, i.e., capturing carbon dioxide (CO2) at its source and storing it indefinitely to avoid its release to the atmosphere. This paper investigates a set of key issues in the development ...

Energies, Vol. 6, Pages 1217-1232: The Influence of Allocation on the Carbon Footprint of Electricity Production from Waste Gas, a Case Study for Blast Furnace Gas

01-03-2013 | Messagie, Maarten ; Boureima, Fayçal ; Mertens, Jan ; Sanfelix, Javier ; Macharis, Cathy ; Mierlo, Joeri Van, Energies, 2013

Producing electricity from waste gas is an after treatment for waste gas while recovering the energy content. This paper addresses the methodology to calculate the effect that waste gas energy recovery has on lowering the impact of climate change. Greenhouse gases are emitted while burning the ...

Energies, Vol. 6, Pages 871-883: Environmental Effects of Sewage Sludge Carbonization and Other Treatment Alternatives

07-02-2013 | Wang, Ning-Yi ; Shih, Chun-Hao ; Chiueh, Pei-Te ; Huang, Yu-Fong, Energies, 2013

Carbonization is a newly developed process that converts sewage sludge to biocoal, a type of solid biomass that can partially substitute for coal during power generation. This study presents an assessment of the environmental effects of various sewage sludge treatment processes, including ...

Energies, Vol. 6, Pages 329-350: Sustainability of the Biorefinery Industry for Fuel Production

14-01-2013 | Caldeira-Pires, Armando ; da Luz, Sandra Maria; Palma-Rojas, Silvia ; Rodrigues, Thiago Oliveira; Silverio, Vanessa ..., Energies, 2013

Biofuels have been extensively explored and applied in the Brazilian market. In Brazil, ethanol and biodiesel are produced on an industrial scale. Ethanol is commercialized and used in engines in both the hydrated form (96% °GL) and the anhydrous form, mixed with gasoline at a proportion of ...

Megacities move to track emissions

06-12-2012 | Tollefson, Jeff;, Nature, 2012

Megacities move to track emissions Nature 492, 7427 (2012). http://www.nature.com/doifinder/10.1038/492020a Author: Jeff Tollefson Scientists monitor greenhouse gases in urban areas as a first step to gauging success of climate ...

Energy consumption and greenhouse gas emissions from enzyme and yeast manufacture for corn and cellulosic ethanol production

20-10-2012 | Jennifer B. Dunn, Steffen Mueller, Michael Wang, Jeongwoo Han, Biotechnology Letters, 2012

Enzymes and yeast are important ingredients in the production of ethanol, yet the energy consumption and emissions associated with their production are often excluded from life-cycle analyses of ethanol. We provide new estimates for the energy consumed and greenhouse gases (GHGs) emitted during ...
