Economic and environmental analysis of a Steam Assisted Gravity Drainage (SAGD) facility for oil recovery from Canadian oil sands
Giacchetta, Giancarlo; Leporini, Mariella; Marchetti, … - In: Applied Energy 142 (2015) C, pp. 1-9
decades. Steam-Assisted Gravity Drainage (SAGD) is the most promising approach for recovering heavy and viscous oil resources …. In SAGD, two closely-spaced horizontal wells, one above the other, form a steam-injector and producer pair. The reservoir … emissions from oil sand production by SAGD technology have been compared with values relating to conventional crude oil pathways …

Energy use and greenhouse gas emissions and related improvement options of the broiler chicken meat supply chain
Katajajuuri, Juha-Matti; Grönroos, Juha; Usva, Kirsi - In: International Journal of Sustainable Development 17 (2014) 1, pp. 49-61
Energy consumption and the climate-change impact (i.e., carbon footprint) of a typical Finnish broiler chicken fillet product were studied using a supply-chain integrated life cycle assessment method. All essential production stages from parent stock and production of farming inputs to product...

Achieving Sustainability of the Energy Sector in Canada
Mourougane, Annabelle - Economics Department, Organisation de Coopération et … - 2008
Energy represents a major sustainable-development challenge for Canada. In the short term, labour shortages and infrastructure bottlenecks are likely to hinder energy developments and need to be addressed. In addition, provincial fiscal management could be improved by adopting prudent allocation...

Should Alberta upgrade oil sands bitumen? An integrated life cycle framework to evaluate energy systems investment tradeoffs
Choquette-Levy, Nicolas; MacLean, Heather L.; … - In: Energy Policy 61 (2013) C, pp. 78-87
The inclusion of greenhouse gas (GHG) emissions costs in energy systems investment decision-making requires the development of a framework that accounts for GHG and economic tradeoffs. This paper develops such a framework by integrating partial cost–benefit analysis with life cycle assessment...

Life cycle energy and greenhouse gas emissions from transportation of Canadian oil sands to future markets
Tarnoczi, Tyler - In: Energy Policy 62 (2013) C, pp. 107-117
Oil sands transportation diversification is important for preventing discounted crude pricing. Current life cycle assessment (LCA) models that assess greenhouse gas (GHG) emissions from crude oil transportation are linearly-scale and fail to account for project specific details. This research...

Energy consumption and greenhouse gas emissions in upgrading and refining of Canada's oil sands products
Nimana, Balwinder; Canter, Christina; Kumar, Amit - In: Energy 83 (2015) C, pp. 65-79
A model-FUNNEL-GHG-OS (FUNdamental ENgineering PrinciplEs- based ModeL for Estimation of GreenHouse Gases in the Oil Sands) based on fundamental engineering principles was developed to estimate the specific energy consumption and GHGs (greenhouse gas emissions) for upgrading bitumen to produce...

The role of ‘indirect’ greenhouse gas emissions in tourism: Assessing the hidden carbon impacts from a holiday package tour
Filimonau, Viachaslau; Dickinson, Janet; Robbins, Derek; … - In: Transportation Research Part A: Policy and Practice 54 (2013) C, pp. 78-91
Tourism is a noticeable contributor to global greenhouse gas (GHG) emissions. Existing estimates of tourism’s carbon footprint are however incomplete as they fail to holistically assess the additional, ‘indirect’ carbon requirements. These arise from the non-use phases of a tourism product...

Ecological-economic assessment of farms using multi-input multi-output models: life cycle assessment with multiple paired comparisons
Hayashi, Kiyotada - In: International Journal of Sustainable Development 17 (2014) 1, pp. 9-21
A multi-input multi-output model is developed by extending the life cycle assessment framework for analysing the relationship between agricultural production and environmental impacts. The inputs include farmland and materials such as fertilisers, pesticides and animals. The outputs are of two...

Energy and climate benefits of bioelectricity from low-input short rotation woody crops on agricultural land over a two-year rotation
Njakou Djomo, S.; El Kasmioui, O.; De Groote, T.; … - In: Applied Energy 111 (2013) C, pp. 862-870
Short-rotation woody crops (SRWCs) are a promising means to enhance the EU renewable energy sources while mitigating greenhouse gas (GHG) emissions. However, there are concerns that the GHG mitigation potential of bioelectricity may be nullified due to GHG emissions from direct land use changes...
