Impacts of greenhouse gas mitigation policies on agricultural land
Greenhouse gas (GHG) emissions are widely acknowledged to be responsible for much of the global warming in the past century. A number of approaches have been proposed to mitigate GHG emissions. Since the burning of fossil-based fuels is an important source of GHGs, the policies on GHG-mitigation …

Modelling New Zealand dairy farm systems to design greenhouse gas mitigation strategies
… account for about 17% of the country’s total greenhouse gas (GHG) load. As the nation progresses in its efforts to reduce these emissions, is likely that the dairy industry will face physical constraints and/or financial costs associated with their mitigation. For this study, a non-linear …

Three Essays On The Interaction Between Global Trade And Greenhouse Gas Mitigation Agreements
<p>The role of trade sanctions in enforcing greenhouse gas mitigation agreements is the fundamental theme of the three essays comprising this dissertation. All three essays employ a multi-sector, multi-region computable general equilibrium model, GTAP-AEZ-GHG, documented in Golub et al. (2009) to …

Greenhouse Gas Mitigation and Management Strategies for Methane Reduction from Waste in Victoria, British Columbia, Canada.
AbstractThis study evaluated greenhouse-gas mitigation and management strategies to reduce methane emissions from waste recycling activities in Victoria, British Columbia. Using a mixed-methods approach that included a literature review, material-flow modelling, and stakeholder policy analysis …

Greenhouse gas mitigation cost of energy from biogas : a techno-economic analysis of co-digestion of three types of waste in Cape Town
… reduction potential (ERP) of energy from biogas and related cost. Two project-scale models and a city-scale model were developed. Substrates for project model 1 were organic fraction of municipal solid waste (OFMSW) and primary sludge (PS) from sewage works. Project model 2 considered waste …

Evaluating soil productivity and climate change benefits of woody biochar soil amendments for the US Interior West
… to better understand the controls on biochar's greenhouse gas mitigation potential. The field studies demonstrate that this woody biochar improved soil moisture content but its enhanced capacity to retain water did not alleviate plant water stress when water inputs were low. Similarly, in forest …

Simulating the Impacts of Land-Use Land-Cover Changes on Cropland Carbon Fluxes in the Midwest of the United States
… fluxes is important for carbon management and greenhouse gas mitigation in agriculture. Past studies found that agricultural land-use and land-cover (LULC) changes, such as changes in cropland production technologies, tillage practices, and planted crop species, could have large impacts on …

Geomechanical Stability Analysis for Co2 Sequestration in Carbonate Formation
<p>Geomechanical analysis is one of the fundamental pillars to build up the confidence of geological sequestration of CO2. Large scale CO2 sequestration in deep carbonate formation is a complicated geological process, which will non-reversibly transform the presumed equivalent and stable status of …

Multi-scale analysis of carbon stocks and process indicators in the agro-ecosystem of Canterbury, New Zealand
… landscape has been driven by the clear need for greenhouse gas mitigation strategies in response to global climate change. However, little quantitative information is available about carbon stocks and processes in agro-ecosystems. Better understanding of carbon stocks and processes is of …

Reducing the global footprint in an anesthesia department : a quality improvement project
Volatile anesthetic agents are potent greenhouse gases with high global warming potential (GWP), long atmospheric lifespans, and significant contributions to perioperative emissions. Despite scavenging systems, a significant portion of these agents are released into the environment, with Desflurane …

Carbon dioxide capture by chemical absorption : a solvent comparison study
… light of increasing fears about climate change, greenhouse gas mitigation technologies have assumed growing importance. In the United States, energy related CO₂ emissions accounted for 98% of the total emissions in 2007 with electricity generation accounting for 40% of the total'. Carbon capture …

Optimizing operation of a campus energy system for economic and environmental considerations
… At current grid electricity and natural gas prices, utilization of a cogeneration unit, a form of combined heat and power plant, is less expensive than purchasing equivalent amounts of electric and gas to produce steam, as long as there is sufficient campus demand for the electricity and …

Evaluation study for an ammonia-fed and solid-oxide fuel cell powered trailing suction hopper dredger for Van Oord Offshore Contractors
In the quest to meet the Paris agreement goals, the maritime industry is facing some serious challenges. To reduce the GHG emissions in the industry, many Zero-Emission technologies and clean fuels have been studied. United Nations’ International Maritime Organization has set the goal to reduce the …
