Carbon Dioxide Emission Standards
On June 25, 2013, President Obama announced his plan to introduce carbon dioxide emission standards for electricity generation. This paper proposes an efficiency analysis approach that addresses which emission rates (and standards) would be feasible if the existing generating units adopt best practices. A new efficiency measure is introduced and further decomposed to identify different sources’...
متن کاملEmission of Carbon Dioxide Influenced by Different Water Levels from Soil Incubated Organic Residues
We studied the influence of different organic residues and water levels on decomposition rate and carbon sequestration in soil. Organic residues (rice straw, rice root, cow dung, and poultry litter) including control were tested under moistened and flooding systems. An experiment was laid out as a complete randomized design at 25°C for 120 days. Higher CO₂-C (265.45 mg) emission was observed in...
متن کاملEffects of soil compaction, rain exposure and their interaction on soil carbon dioxide emission
Soils release more carbon, primarily as carbon dioxide (CO2), per annum than current global anthropogenic emissions. Soils emit CO2 through mineralization and decomposition of organic matter and respiration of roots and soil organisms. Given this, the evaluation of the effects of abiotic factors onmicrobial activity is of major importance when considering the mitigation of greenhouse gases emis...
متن کاملTillage, cropping sequence, and nitrogen fertilization effects on dryland soil carbon dioxide emission and carbon content.
Management practices are needed to reduce dryland soil CO(2) emissions and to increase C sequestration. We evaluated the effects of tillage and cropping sequence combinations and N fertilization on dryland crop biomass (stems + leaves) and soil surface CO(2) flux and C content (0- to 120-cm depth) in a Williams loam from May to October, 2006 to 2008, in eastern Montana. Treatments were no-tille...
متن کاملTillage and crop residue effects on soil carbon and carbon dioxide emission in corn-soybean rotations.
Soil C change and CO2 emission due to different tillage systems need to be evaluated to encourage the adoption of conservation practices to sustain soil productivity and protect the environment. We hypothesize that soil C storage and CO2 emission respond to conservation tillage differently from conventional tillage because of their differential effects on soil properties. This study was conduct...
